2.3 DDC SIGNALS (VESA DDC1/2B)

This monitor is equipped with VESA DDC 1/2B according to VESA DISPLAY DATA

CHANNEL STANDARD V. 1.0 Rev.1 (tt.mm.199j)

It transmits the EDID-file as a continuous data stream, clocked by V-SYNC (DDC 1); the

controller may increase the Vert. frequency to 25 kHz max. for improved transmission rate.

As an alternative, it sends the EDID-file upon request by the host-system (Read EDID,

Device A0h Start address 00h) in an I2C compatible format (DDC 2).

The monitor has installed a 10kΩ pull-up on the SCL-line (pin 15 of 15-pin

VGA-connector).

It is applied to check the deflection linearity And for pin-cushion correction Full screen definition pattern of 8vert. Bars 0.8MHz to 4.8MHz.

Contains eight full screen vertical bars of definition lines in the frequency ranges 0.8,

1.8,2.8,3.0,3.2,3.4,3.8,and 4.8 MHz This checks the bandwidth of the video or luminance amplifier in black and white or color TV as well as the resolution of monitor and video recorders The vertical bars are white, yellow, cyan, green, magenta, red, blue, and black. The luminance content depends on the TV system selected and is automatically correct after the user makes the selection. The color bar pattern in fact provides sufficient information for a good overall check on color performance. This includes the checks on burst keying, sub-carrier regeneration, RGB amplifiers, the delay color versus B/W signal and saturation check Check the bandwidth , linearity , sensitivity , and AGC of the chroma amplifiers in color video recorders . This combined test pattern is divided into the following four horizontal segments:

-Horizontal 100% white bar covering 1/16 field for exact level adjustment

-Eight bars of resolution of which

2.8-3.0-3.2-3.4MHz are used to align the high-pass filter for a maximum resolution in VCR bandwidth

-The next part of the pattern contains eight steps of decreasing linear levels of saturation of 100%to 0% to check the chroma amplifier linearity and color AGC circuitry. For example, if the chroma writing current is too high, color will be visible in the last bar where no color should be seen normally

-The bottom section consists of black horizontal bar with a moving white field to check moving pictures on video recorders

2.8.1.1 Teletext Teletext is an optional function, therefore only the set of the teletext system can receive the teletext broadcast. Teletext is a free service broadcast by most TV stations which gives up-to-the-minute information on news, weather, television programs, stock prices and many other topics. The teletext decoder of this TV can support the SIMPLE, TOP and FASTEXT systems. SIMPLE (standard teletext) consists of a number of pages which are selected by directly entering the corresponding page number. TOP and FASTEXT are more modern methods allowing quick and easy selection of teletext information.

Switch ON/ OFF

Press the TEXT

button to switch the teletext. The initial page or last page appears on the screen. Two page numbers, TV station name, date and time are displayed on the screen headline. The first page number indicates your selection, while the second shows the current page displayed. Press the TEXT

or TV/AV/PC button to switch off teletext. The previous mode reappears.

SIMPLE text Page selection

1. Enter the desired page number as a three-digit number with the NUMBER buttons. If you press

a wrong number during selection, you must complete the three-digit number and then reenter the correct page number.

2. The ↑ / ↓ button can be used to select the previous or next page.

Programming a color button in LIST mode

If the TV is in SIMPLE text, TOP text or FASTEXT mode, press the “MODE ” button to switch to LIST mode. Four teletext page numbers of your choice can be colored and easily selected by pressing the corresponding colored button on the remote control handset.

1. Press a colored button.

2. Using the NUMBER buttons to select the page you wish to program.

3. Press the button. Then the selected page is stored as the selected page number with blinking

once. From now on, you can select this page with the same colored button.

4. The three other colored buttons are programmed in the way.

TOP text

The User’s Guide displays four fields-red, green, yellow and blue at the bottom of the screen. The yellow field denotes the next group and blue field indicates the next block.

Block/ group/ page selection

1. With the blue button you, can progress from block to block.

2. Use the yellow button to proceed to the next group with automatic overflow to the next block.

3. With the green button, you can proceed to the next existing page with automatic overflow to the

next group. (Alternatively the ↑ button can be used.)

4. The red button permits you to return to the previous selection. (Alternatively the ↓ button can be

used.)

Direct page selection

In the SIMPLE teletext mode, you can select a page by using the NUMBER buttons in TOP mode to enter the three-digit number.

FASTEXT

The teletext pages are color coded along the bottom of the screen and are selected by pressing the corresponding colored button.

Page selection

1. Press the “INDEX ” button to select the index page.

2. You can select the pages which are color coded along the bottom line with the same colored

buttons.

3. Corresponding to the SIMPLE teletext mode, you can select a page by entering its three-digit

page number with the NUMNER buttons in FASTEXT mode.

4. The ↑ / ↓ button can be used to select the previous or next page.
