Introduction

Congratulations on purchasing the Presenter, Silicon Graphics’ 1024 x 768 full-color, ﬂat-panel monitor with stereo speakers and overhead projection capability.

This guide assumes that the hardware adapter board for the Presenter is installed in your workstation. If it is not, install it ﬁrst, following the instructions in the manual that comes with the adapter board.

Chapter 1 explains how to set up the Presenter as a monitor for your workstation and how to use it on the Silicon Graphics® customized Dukane® overhead projector. You can use the Presenter with either the Dukane 28A681 or 28A682 projectors.

Chapter 2 contains troubleshooting and product support information. It also explains how to clean the Presenter, and how to pack it for shipping.

Chapter 3 provides technical speciﬁcations and regulatory information.

Appendix A provides technical information on liquid crystal display technology.

Chapter 1

1. Setting Up and Using the Presenter Monitor

This chapter explains how to set up Presenter as a monitor for your workstation, and how to use it on the customized Dukane overhead projector to project images on a screen.

Before using Presenter, make sure the Presenter adapter board has been installed in your workstation.

Caution: Your Presenter monitor is designed to function at maximum

performance and reliability with the Dukane Overhead Projector. If you use another projector, cooling of the display, stable mounting, and brightness of the projected image will all be compromised. A bright overhead projector without proper cooling of the display may cause permanent damage to Presenter.

Setting Up the Presenter Monitor

To set up Presenter with the workstation, follow these steps.

1. Unpack the Presenter monitor.

Note: Don’t be concerned that the name on the Presenter monitor is

“Indy Presenter.” With the Presenter adapter board installed, the Indy

Presenter works on other workstations.

■ Lift the Presenter monitor and the external cables from the box. It’s

a good idea to save the original shipping materials in the event that you need to return it for service.

■ Remove Presenter from the plastic bag.

Chapter 1: Setting Up and Using the Presenter Monitor

2. Remove the protective ﬁlm from the screen, being careful not to get ﬁngerprints on the coated-glass surface.

The display is made of glass, coated with optical ﬁlms and is the most expensive component in the Presenter. A sharp instrument such as a pen can scratch the surface. Striking the surface with a hard object can break the glass.

3. Tilt the base of the Presenter to form a stand, as shown in Figure 1-1, and place it on a ﬂat surface.

Note: You can leave your CRT monitor connected to the workstation while

using the Presenter.

Speakers

Figure 1-1 Front View of the Presenter

You are now ready to connect the Presenter monitor’s external cables.

Setting Up the Presenter Monitor

Connecting the Cables

If the Presenter board is not already installed in your workstation, install it now, referring to the installation manual that comes with it.

To use the Presenter monitor, you must connect two cables:

• the interface cable (the one with identical ﬂat connectors at each end)

• the power cable

Note: You do not need to turn off the workstation before connecting the

cables.

Chapter 1: Setting Up and Using the Presenter Monitor

Follow these steps to connect the cables.

1. Connect the interface cable to the Presenter. It’s important that you connect the interface cable before the power cable.

The connectors on the cable and on the Presenter have an elongated “D” shape. Make sure the “D” shapes match each other.

■ Connect either end of the interface cable to the connector on base of

the Presenter, as shown in Figure 1-2.

■ Connect the other end of the interface cable to the Presenter adapter

I/O port on your workstation. If necessary, refer to the installation manual that comes with the Presenter board.

To workstation

Figure 1-2 Connecting the Interface Cable to the Presenter

Setting Up the Presenter Monitor

2. Connect the power cable to the Presenter and then to an electrical

outlet, as shown in Figure 1-3. (Figure 1-3 shows the power cable for the U.S.A. The power cable for your country may look different.)

■ Connect the socket end to the power connector on the base of the

Presenter.

■ Connect the other end to a three-pronged grounded electrical wall

outlet or power strip.

Note: The power supply for the Presenter is auto-ranging. With the

appropriate power cable or adapter for your country, you can plug the Presenter into almost any power source (50-60 Hz, 110/220 VAC).

To workstation

Figure 1-3 Connecting the Power Cable

You are now ready to use the Presenter monitor.

Chapter 1: Setting Up and Using the Presenter Monitor

Turning on the Presenter

The Presenter has no power switch. If your workstation and CRT monitor are on when you connect the Presenter, you start the Presenter from the Monitor Control Panel. See “Starting Presenter With the Monitor Control Panel” below.

If your workstation is off when you connect Presenter, turning on the workstation automatically turns on Presenter. The display takes about a minute to warm up, so the image may appear dim at ﬁrst.

If there is no image on the Presenter, make sure the external cables are connected correctly, as described in “Connecting the Cables” on page 3. Then go to Chapter 2, “Troubleshooting” for help in solving the problem.

Note: If you have a high resolution (1280 x1024 pixels) CRT monitor

connected to the workstation and you connect the Presenter, the CRT monitor is set to 1024 x 768 pixels. Therefore icons at the extreme edges of your screen may not be visible. To remedy this, move the icons away from the edges of the screen before turning on the Presenter. If you disconnect the Presenter and wish to return your CRT monitor to its default resolution, type the following from a UNIX shell:

su /etc/killall Xsgi

If the workstation is on and Presenter is disconnected, see “Restarting the Presenter Monitor” on page 7.

Starting Presenter With the Monitor Control Panel

If your workstation and CRT monitor were already on when you connected Presenter, follow these steps to start it:

1. On the CRT monitor, open the Monitor Panel in either of the following ways:

• From the Find menu in the Toolchest, choose “Control Panels,” and double-click the monpanel icon.

Turning on the Presenter

• From a UNIX shell, enter:

monpanel

2. When the Monitor Control Panel appears, click Turn on Presenter or

Restart Presenter.

If you have a root password set, enter it when prompted, and click the OK button.

If your CRT monitor is 1024 x 768 pixels, you see a message that turning on the Presenter stops all running applications. Close any applications for which you may lose data.

3. When you are ready for applications to be stopped, click Continue to

turn on Presenter.

For more information on using the Monitor Control Panel for the Presenter, see the reference page (man page). From a shell window, type:

man monpanel

Restarting the Presenter Monitor

If the workstation is on and Presenter is disconnected, you can reconnect it and restart it from the Monitor Control Panel on the CRT monitor. See the steps below. Note that restarting the Presenter resets the backlight and bit mode to their original settings, that is, nearly full backlight and 12-bit mode.

If you have no CRT monitor attached there are two ways you can restart Presenter:

• Reconnect Presenter and restart the workstation.

• If you are on a network, use the Monitor Control Panel to restart the

Presenter. From another system on the network, log in to your system remotely, and type monpanel -restart at the shell prompt.

Follow these steps to restart Presenter:

1. Open the Monitor Panel in either of the following ways:

■ From the Find menu in the Toolchest, choose “Control Panels” and

double-click the monpanel icon.

Chapter 1: Setting Up and Using the Presenter Monitor

■ From a UNIX shell, enter:

monpanel

2. When the Monitor Control Panel appears, click Restart Presenter.

Turning Off the Presenter

The Presenter turns off automatically when you turn off the workstation.

If you have a CRT monitor connected to your workstation, you can disconnect the Presenter’s interface and power cables instead of powering off the workstation. To restart the Presenter, connect the interface cable and then the power cable. Then open the Monitor Control Panel on the CRT monitor by choosing “Control Panels” from the Find menu in the Toolchest and double-click the monpanel icon. Then click Restart Presenter.

Note: It’s important when you reconnect the Presenter’s cables that you

connect the interface cable ﬁrst and then the power cable. Connecting them in the reverse order results in a distorted image.

If no CRT monitor is connected to the workstation, you can disconnect the Presenter’s interface and power cables instead of powering off the workstation. To restart the Presenter, reboot your workstation after connecting the interface cable and the power cable.

If you are not planning to use the Presenter for a few hours, it’s a good idea to disconnect it. Leaving the display on for long periods of time shortens the life of the display’s backlight.

Setting Up the Presenter on the Dukane Customized Projector

Caution: The Presenter is designed to function at maximum performance

and reliability with the Dukane Overhead Projector. If you use it with another projector, cooling of the display, stable mounting, and brightness of the projected image will all be compromised. A bright overhead projector

without proper cooling of the display may cause permanent damage to the Presenter.

Setting Up the Presenter on the Dukane Customized Projector

Follow these steps to set up the Presenter with the Silicon Graphics customized Dukane Overhead Projector. You can use the Presenter with either the Dukane 28A681 or 28A682 projector. However the audio capability on the Dukane 28A682 is not supported on the Presenter.

1. Remove the overhead projector from its carrying case.

2. Raise the arm to its upright position, using the illustration on the

overhead projector as a guide.

3. Lock the arm in place with the locking knob. See Figure 1-4.

4. Rotate the lens mechanism and raise the mirror, as shown in Figure 1-4.

5. Turn on the overhead projector. Note that it takes about a minute to warm up. An initial bright ﬂash followed by a dark interval before the brightness increases is normal.

6. Choose the projector lens appropriate for your task.

■ If you are projecting over a distance of more than 6 feet, you

probably won’t want to use the projector’s wide-angle lens with Presenter. Rotate the wide-angle lens away from the standard lens.

■ If you are projecting a larger image from a short distance, use the

wide-angle lens.

7. If the power cable and interface cable are not already attached to Presenter 1280 and to your workstation, connect them now. (See “Connecting the Cables” on page 3 if necessary.)

8. If Presenter is not already on, turn it on or restart it in either of the following ways:

■ If you have a CRT monitor attached, open the Monitor Control

Panel. From the Find menu int he Toolchest, choose “Control Panels” and double-click the monpanel icon. Click Turn On or Restart.

■ Or press and release the power button on the front of the

workstation to turn on the Presenter and the workstation.

Setting Up the Presenter on the Dukane Customized Projector

9. Remove the backlight panel from Presenter.

■ Place it face down on a ﬂat surface.

■ Press in the latches on either side of the panel and tilt it up and

remove it. See Figure 1-5. This automatically turns off the Presenter’s backlight.

Caution: Do not place Presenter with the backlight panel attached on

an overhead projector that is turned on. This causes overheating, and will damage Presenter.

Latches

Figure 1-5 Removing the Backlight Panel

10. Carefully place the backlight panel on a surface where it will not get

damaged or scratched. Scratches will not affect performance, but if they are large enough, you will see them through the display. Do not touch the coated-glass surface of the display with your hands or with any instrument. Even a pen tip can scratch the surface.

Chapter 1: Setting Up and Using the Presenter Monitor

11. Place the Presenter face down on the surface of the overhead projector so that only the back of the Presenter is visible, and slide it under the two clips on the projector to secure it. See Figure 1-6. Make sure the backlight

panel has been removed ﬁrst.

■ Slide the Presenter under the two clips on the projector.

■ Rotate the base of the Presenter down so it is out of your way.

Figure 1-6 Placing the Presenter on the Overhead Projector

12. Open the ﬁle for the image on the Presenter that you wish to project.

If the image does not project properly, check that the Presenter is face down on the projector’s surface, and that the backlight panel has been removed. For additional help, go to Chapter 2, “Troubleshooting.”

If you think the problem might be with the Dukane overhead projector, refer to its manual.

13. When you are ﬁnished with your presentation, turn off the overhead projector, and replace the backlight panel, as shown in Figure 1-7.

Setting Up the Presenter on the Dukane Customized Projector

Caution: Make sure you turn the projector off before replacing the

backlight panel. Having both light sources on at the same time can permanently damage the display.

■ Tilt the backlight panel and insert the lower edge into the slots on

the Presenter.

■ Lower the panel over the Presenter, aligning the two catches.

■ Press down lightly until you hear a click as the catches engage.

It takes a few minutes for the backlight to reach full brightness again.

2. To adjust the brightness of the display, move the slider.

Note: For more information on using the Monitor Control Panel for the

Presenter, see the reference page (man page). From a shell window, enter:

man monpanel

Switching to 15-Bit Color Mode

The default color mode on the Presenter is 12-bit. In this mode, some smooth shaded images appear banded. If you wish to decrease this banding, you can do so by switching to 15-bit mode. In that mode, however, some colors ﬂicker. So you may want to switch back and forth, depending on the types of images you are viewing.

To switch between 12-bit and 15-bit mode, use the Monitor Control Panel. Follow these steps:

1. Open the Monitor Panel in either of the following ways:

■ From the Find menu in the Toolchest, choose “Control Panels” and

double-click the monpanel icon.

■ From a UNIX shell, enter:

monpanel

2. Click 15-bit mode.

Note: The resolution of 1024 x 768 pixels is ﬁxed and cannot be changed.

Only the color resolution can be changed.

Adjusting the Brightness

Adjusting the Volume and Tone of the Speakers

The Presenter stereo speakers are designed to work with the standard speaker on your workstation. You adjust the volume and tone of the Presenter speakers through the Audio Panel and the Presenter Audio Panel under the Options menu of the Audio Panel.

Follow these steps to adjust the volume and tone:

1. Open the Audio Panel in either of the following ways:

■ From the Desktop menu in the Toolchest, choose “Audio Control.”

■ From a UNIX shell, enter:

apanel

2. From the Options menu on the Audio Panel, choose “Presenter Audio.”

3. Adjust the tone and volume by using the Speaker controls on the

Presenter Audio panel.

While the Presenter Audio panel is open, you can use the workstation’s front panel volume controls. Or you can adjust the volume of the Presenter speakers independently of the workstation speakers by selecting “Output Sliders Independent” from the Audio Panel Options menu.

4. To mute the Presenter speakers, click the Mute button on the Presenter

Audio Panel.

For further information on the Audio Panel:

• Select “On-line Books” from the Help menu in the Toolchest. Choose

Media Tools User’s Guide and search for “Audio Panel.”

• From a shell window, enter:

man apanel

to see the reference page (man page).

Chapter 1: Setting Up and Using the Presenter Monitor

Using Headphones

If you use headphones, you probably want to mute the Presenter stereo speakers temporarily. Follow these steps to do this:

1. Open the Audio Panel in either of the following ways:

■ From the Desktop menu in the Toolchest, choose “Audio Control.”

■ From a UNIX shell, enter:

apanel

2. Select “Presenter Audio” from the Options menu.

3. Click Mute on the Presenter Audio panel to mute the Presenter speakers.

Tip: Note that clicking the Mute button on the main Audio Panel mutes

only the workstation speakers, and not the Presenter speakers.

Using a Screen Saver

Do not disable your workstation’s screen saver program when using the Presenter. As with any CRT monitor, leaving an image up without a screen saver for a long time may burn the image into the display.

If you are not planning to use the Presenter monitor for a few hours, it’s a good idea to disconnect it. Leaving the display on for a long time shortens the life of the display’s backlight lamps.

Chapter 2

2. Troubleshooting

This chapter contains information on solving problems that you may encounter when using Presenter.

If you think there may be a problem with your Presenter, read the following sections to help isolate and solve it. If the problem persists after following these suggestions, call your service provider.

Problems with the Presenter Monitor

The suggestions in the following sections will help you isolate the problem.

No Image

1. Check that the power cable is connected securely to the Presenter and

to a working wall outlet or power strip.

2. Check that the interface cable is connected securely to the Presenter and

to the correct connector on the rear of the workstation. (See “Connecting the Cables” on page 3.)

3. Make sure that the workstation is turned on. There is no On/Off switch

on the Presenter. If the cables are connected correctly, the Presenter turns on automatically when you turn on the workstation. The Presenter takes about a minute to warm up to full brightness.

4. If you recently installed the Presenter board in your workstation, the

board may not be installed correctly, or it may be installed in the wrong slot. Follow the instructions in the installation manual that came with the board to make sure the hardware is installed correctly.

Chapter 2: Troubleshooting

5. If Presenter was not connected to the workstation via the interface cable when the workstation was turned on, connect the interface cable. Connect Presenter’s power cable to a working wall outlet. Then, if you have a CRT monitor connected, use the Monitor Control Panel to restart the Presenter:

■ From the Find menu in the Toolchest, choose “Control Panels.”

■ Double-click the monpanel icon.

If you have no CRT attached, restart the workstation. Or if you are on a network, log in to your system remotely, and type monpanel -restart at the shell prompt.

6. If you are using Presenter as a desktop monitor, (that is, you are not using it on an overhead projector), check that the backlight panel is fully seated. Full contact is required to turn on the backlight.

7. Try restarting the workstation.

Image Is Too Light or Too Dark

1. Flat panel displays take about a minute to warm up after being turned on. Until the Presenter has warmed up, the image may appear faded or dim.

2. Flat panel displays look different when viewed from different angles. If you view from above, the display appears dark. If you view from below, the display appears light.

The display is best viewed from slightly above straight on. Tilt the display base forward or back to ﬁnd the best view.

Image Is Distorted

When you connect the Presenter, if the image is distorted it may be because you connected the power cable before the interface cable. Remove the cables from the Presenter. Connect the interface cable ﬁrst and then the power cable. Then reboot your workstation.

Problems with the Presenter Monitor

Backlight Stays on When Back Panel is Removed

Occasionally, after you remove the backlight panel on the Presenter, the backlight stays on, and the image is reversed.

There is a magnetic reed switch located on the back side of the Presenter in the middle of the backlight slot. If this switch is stuck, tap it lightly to break it free.

Screen is White

If the screen is white, the Presenter hardware needs to be reset. To do this, unplug the power cord from the Presenter while the workstation is on, and then plug it back in. If there is a CRT monitor connected to your workstation, restart the Presenter from the Monitor Control Panel. (See “Restarting the Presenter Monitor” on page 7.) Or if you are on a network, log in to your system remotely, and type monpanel -restart at the shell prompt.

Vertical Streaks Above or Below Edges of Windows

If you have several windows open on the screen and you are using the Presenter as a desktop monitor, you may see faint vertical streaks above or below the left or right edges of a window. Or you may see a light band across the bottom edge of the screen below a window.

This is caused by crosstalk between transistors in the panel, and is normal in liquid crystal display technology. The faint streaks do not detract from the functionality of the display. You can minimize them by rearranging the windows, choosing a different background, or adjusting the brightness of the display to about 90% of maximum through the Monitor Control Panel.

If the streaks become so bright as to detract when using the Presenter on an overhead projector, contact your service provider about a solution to the problem.

Chapter 2: Troubleshooting

Icons at the Edges of the Screen Not Visible

When you switch from a high resolution (1280 x 1024 pixels) CRT monitor to the Presenter, icons that were on the upper and right edges of the screen may disappear. This is because the CRT monitor changes to 1024 x 768 pixels. There are two ways to ﬁx this:

1. Move the icons away from the edges of the screen on your CRT monitor before connecting the Presenter.

2. Or unplug the Presenter power cable, and from a shell window on your CRT monitor, type the following:

su /etc/killall Xsgi

This returns the CRT monitor to 1280 x 1024 pixels. Then move the icons away from the edges of the screen. Reconnect the Presenter’s power cable, and restart the Presenter from the Monitor Control Panel. (See “Restarting the Presenter Monitor” on page 7.)

No Sound From the Stereo Speakers

1. If the Presenter board kit for your workstation included a short, black, audio cable, check that the small, black audio cable is installed correctly. If necessary, see the manual that comes with the Presenter board for your workstation.

2. The stereo speakers may have been muted in order to use headphones. To turn on the speakers, choose “Control Panels” from the Find menu in the Toolchest and double-click the apanel icon. Select “Presenter Audio” from the Options menu. If the Mute button on the Presenter Audio panel is activated, click on it to turn on the speakers.

Problems with the Dukane Overhead Projector

The suggestions in the following section will help you isolate the problem. For more information on the Dukane projector, see the manual that comes with it.

No Image on the Overhead Projector or Image Is Reversed

1. Check that the overhead projector is turned on and glowing brightly.

The overhead projector takes about a minute to warm up. (Refer to the manual that comes with the projector.)

2. Check that the Presenter is placed face down on the overhead projector.

3. Make sure that the Presenter’s backlight panel has been removed.

4. The bulb in the Dukane overhead projector may be burned out. The

bulb is a long-life bulb, but usually needs replacing after 750 hours of use.

Radio and Television Interference

The equipment described in this guide generates and uses radio frequency energy. If it is not installed and used in accordance with the instructions in this guide, it can cause radio and television interference.

This equipment has been tested and complies with the limits for a Class A computing device in accordance with the speciﬁcations in Part 15 of FCC rules. These speciﬁcations are designed to provide reasonable protection against such interference in an industrial or ofﬁce installation. However, there is no guarantee that the interference will not occur in a particular installation. This system is not certiﬁed for home use.

You can determine whether your system is causing interference by turning it off. If the interference stops, it was probably caused by the workstation or one of the peripherals. To tell if the interference is caused by one of the peripherals, try disconnecting one peripheral at a time to see if the interference stops. If it does, that peripheral is the cause of the interference.

If your workstation does cause interference to radio or television reception, try to correct the interference by using one or more of the following suggestions:

• Turn the television or radio antenna until the interference stops.

• Move the workstation to one side or the other of the radio or television.

• Move the workstation farther away from the radio or television.

• Plug the workstation into an outlet that is on a different circuit from the

radio or television. (That is, make certain the workstation and the radio or television are on circuits controlled by different circuit breakers or fuses.)

Electrostatic Discharge

Silicon Graphics designs and tests its products to be immune to effects of electrostatic discharge (ESD). ESD is a source of electromagnetic interference and can cause problems ranging from data errors and lockups to permanent component damage.

Chapter 3: Maintenance, Technical Specifications and Regulatory Information

It is important that while you are operating your workstation you keep all the covers and doors, including the plastics, in place. The shielded cables that came with the system and its peripherals should be installed correctly, with all thumbscrews fastened securely.

An ESD wrist strap is included with some products, such as memory and graphics upgrades. The wrist strap is used when installing these upgrades to prevent the ﬂow of static electricity, and it should protect your system from ESD damage.

Shielded Cables

The workstation is FCC-compliant under test conditions that include the use of shielded cables between the workstation and its peripherals. Your workstation and any peripherals you purchase from Silicon Graphics have shielded cables. Shielded cables reduce the possibility of interference with radio, television, and other devices. If you use any cables that are not from Silicon Graphics, make sure they are shielded. Telephone cables do not need to be shielded.

The monitor cable supplied with your system uses additional ﬁltering molded into the cable jacket to reduce radio frequency interference. Always use the cable supplied with your system. If your monitor cable becomes damaged, a replacement cable should be obtained from Silicon Graphics.

Product Safety

Caution: The power cord is used as a disconnect device. The socket outlet must be installed near the equipment and must be easily accessible.

Achtung: Die Netzzuleitung dient als Trennvorrichtung. Die Steckdose sollte sich nahe am Gerät beﬁnden und leicht zugänglich sein.

Appendix A

A. Liquid Crystal Display (LCD) Technology

This section contains technical information on liquid crystal display technology.

The key component in the Indy Presenter is the active matrix display module. It is composed of twisted nematic liquid crystal material, sandwiched between two sheets of glass, activated by electronic switches deposited on the inner surface of the glass. The electronic switches vary the voltage applied to the liquid crystal and thus change its transparency.

Vertical stripes of alternating red (R), green (G), and blue (B) colored ﬁlters made of organic dyes are located on the front glass plate, under a transparent indium tin oxide electrode. The intersection of each of these colored stripes with an active electronic element forms a subpixel of that color.

The electronic switches on the back glass are known as thin ﬁlm transistors (TFTs) and are addressed in an x-y matrix from integrated circuit drivers. These drivers, bonded to ﬂexible circuits by tape automated bonding (TAB) techniques, are located around the display edges in the plane of the glass package. Conductive thermoplastic adhesive strips connect the TAB tapes and the electrodes on the TFT glass panel. The assembly is held together by a stamped metal bezel.

A backlight assembly behind the display glass consists of an acrylic light pipe, plastic diffuser, and cold cathode ﬂuorescent (CCF) tubes. Four tubes, two at the top and two along the bottom, produce a bright image with high color saturation.

In Silicon Graphics, Inc.’s implementation, the acrylic light pipe is attached to a rear door that is removable by the user, so the display can be used with

Appendix A: Liquid Crystal Display (LCD) Technology

an overhead projector. When the door is removed, a switch opens that disables the CCF tubes and reverses the data stream to the display, causing the image to be ﬂipped right to left. The display can therefore be placed face down, instead of back down, on the projector stage. This is important because it places the color ﬁlter layer between the powerful projector beam and the somewhat light-sensitive TFT plate.

In operation, the TFT devices activate subpixel elements in the display by causing a voltage potential across selected portions of the liquid crystal material. These elements are used as variable shutters to control the intensity of white light coming from the CCF panel and reaching the red, green, or blue ﬁlters. Combinations of these subpixel elements produce a full pixel (RGB triad) of the proper hue, saturation, and brightness much like a cathode ray tube (CRT).

Differences Between LCD and CRT Technology

If you are accustomed to using a CRT monitor, you will notice that the Presenter’s ﬂat panel display is remarkably different.

One of the most noticeable differences is the crispness of text. A CRT pixel is formed by a beam of electrons that scans across the screen. Thus pixels “bloom” at the fuzzy edge of the electron beam and smear into each other as the beam moves. The Presenter’s pixels are formed by a combination of light valve and color ﬁlter that produces an extremely crisp edge for each subpixel. You can actually see these red, green and blue subpixels when using the Presenter in Overhead Projector mode if you stand very close to the projector screen.

Another difference is the lack of distortion in the image displayed by the Presenter. There are two reasons a CRT cannot achieve this: the physics of creating glass tubes makes it almost impossible to make them ﬂat, and the magnetics of controlling an electron beam makes it almost impossible to get straight lines everywhere on the CRT.

A third difference is the lack of ﬂicker on the Presenter ’s ﬂat panel. CRTs ﬂicker because the electron beam can only be in one place at a time. Thus each pixel on a CRT is being driven only about a millionth of the time. The phosphor has a “persistence” that causes it to emit light over a little longer period, but it still ﬂickers. In the Presenter’s ﬂat panel, all pixels are being

Quality

driven all the time. Thus the pixels that are not changing in value look perfectly stable.

A fourth difference, which actually works in the CRT’s favor, is the electrical phenomenon of crosstalk between the pixels on a ﬂat panel. In a ﬂat panel, whole columns of pixels are powered from the same electronic source. That source bus is a very thin line that hides in the space between the pixels. The result is that with some displayed images, the pixels above or below the image do not receive enough electrons and thus appear lighter than they should. In the worst case, you may see faint vertical streaks on the display. You will probably see them only if you have a solid background and are using the Presenter as a desktop monitor. The streaks are normal in LCD technology. If they become so bright as to always detract from the display’s performance, however, contact your service provider about a solution to the problem.

The resolution of the Indy Presenter is 1024 x 768 pixels. Therefore your display has 1024 x RGB x 768, or 2,259,296, subpixels — all in an area equivalent to 2.5 times that of a 6-inch silicon wafer. Current technology is not capable of producing a 100% defect-free active matrix display at reasonable costs, although yields are improving steadily. Your Presenter may exhibit a small number of isolated subpixel dropouts, which have been individually screened to make certain they are in unobtrusive locations.

Backlight Brightness

The output of a ﬂuorescent lamp strongly depends on the minimum bulb wall temperature, because this temperature determines the mercury vapor pressure inside the lamp. The colder the temperature, the more mercury condenses on the inside of the bulb, resulting in decreased light output. At 25°C, the light output is at approximately 80% of its optimum temperature, but at 10°C, the light output could easily degrade to 30% of its maximum. Therefore it takes about one minute for the lamps to warm up to full brightness from a cold start.
