5. FAQ
Q: While installing on my PC
, my computer loses the Vertical Sync.
A:
Please check your monitor’s specifications. Some monitors connect the DDC
signal to ground: Which causes the BIOS not to detect your monitor. Therefore, causing your MVGA
-NVG11A/P /AL/AT/PT not to receive any data or refresh
rates.
Q:
The image on my monitor keeps on flickering and the driver can't
change the refresh-rate.
A:
The problem is due to a failed DDC monitor detection. To fix the problem:
1. Chick the right button of mouse in desktop them choose ‘Properties’.
2. Select ‘Settings’ tab
3. Click ‘Advanced Properties’
4. Select ‘Monitor’ tab
5. Click ‘Change’
6. Select ‘
Show All Devices’ and choose your monitor type.
If your mo
nitor
type is not listed, please select one that is similar as possible.
Q: How do I change the resolution, color, and refresh-
rate on my
Windows 98SE system?
A:
Open the ‘
My Computer’ folder and select the ‘Control Panel’ icon.
Double-click on ‘Display
’ icon, then select ‘
Settings
’ tab, and then choose
Color Palette colors’ to change the
color
values. Adjusting ‘Screen area’ to
change the Resolution (screen image size). From the same tab click-
on
Advanced… ’ to access the Refresh-rate.
Q: How do I change the resolution, color, and refresh-
rate on my
Windows NT system?
A:
The procedure is basically the same as the Windows 98SE system. Except that you must select ‘Test’ then click ‘OK’, so that the changes can take affect.

Q: TV-
OUT is grayed out on my TV-OUT capable
MVGA-
NVG11A/P
/AL/AT/PT. How can I fix it?
A:
1. The MVGA-NVG11A/P/AL/AT/PT needs to see real 75 ohms AV input.
However, not all TVs have this, and some have a switch labeled ‘Terminate’ next to the AV inputs to turn the 75 ohms off to allow more than one TV to be connected. If you are having this problem, especially with a smaller or
portable TV, then try another TV to see if this is a problem, or check for a ‘Terminate’ switch.
2. According to motherboard vendor this may als
o be caused a problem by motherboards using a linear voltage regulator that does not supply enough voltage to the
MVGA-NVG11A/P
/AL/AT/PT, and therefore there is not
enough voltage to maintain TV-OUT.
Q: My MVGA-NVG11A/P
/AT/AL/AT/PT keeps on locking up. How can I fix
it?
A:
1.
Are you over clocking either
MVGA-
NVG11A/P/AL/AT/PT or your
processor? If you are, try clocking back to normal, leaving the case lids off and under clocking and see if it fixes the problem. If it does, you need more cooling.
2. Have you assigned an IRQ to VGA in your BIOS? If not, do so.
3.
Have you got an IRQ conflict with
MVGA-
NVG11A/P/AL/AT/PT and another card? The only device that can have the same IRQ is the ‘IRQ Holder for PCI Steering’. If so, try moving the card to another slot (in
particular avoid the first PCI slot as this frequently is forced to share an IRQ with the AGP slot) or assigning a different IRQ to that slot in the BIOS.
4. Are you running a virus checker in the background? Try disabling it.
5. Try inst
alling the latest AGP drivers for your motherboard chipset if you
haven't got an Intel motherboard.
6.
If you have an ‘AGP Driving Control’ setting in your BIOS, try switching it
to ‘BA’ or another value instead of ‘Auto’.
7.
If you have a VIA chipset,
try enabling AGP4X. We have chosen to disable the AGP sideband transfer because there have been various system instability problems due to issues in the design of some motherboards.
Q: The system will hang up when I play 3D game in Win98SE system.
A:
1.
Start Þ ProgramsÞ AccessoriesÞ
System Tools

2.
ToolsÞ
DirectX Diagnostic Tool
Þ Display
3. Disable ‘Direct3D Acceleration’ to try.

Q:
When I install the 5.xx series of drives Windows 9x locks up at the
bootup screen. How can I fix it?
A:
Make sure your
MVGA-NVG11A/P/AL/AT/PT is not sharing an IRQ with any other devices. If you find that it is, try either moving the device into another PCI slot, or reassigning the PCI IRQs in the BIOS. In particular, the first PCI slot is frequently forced to share an IRQ with the AGP slot.
Q:
If I set the
MVGA-NVG11A/P
/AL/AT/PT as the primary card in the
BIOS, my secondary PCI video card is not detected. How can I fix it?
A:
Check in your C:
\CONFIG.SYS file to see if you are loading EMM3
86.EXE. If
you are, remove the line.
Q: Games stutter with my MVGA-
NVG11A/P/AL/AT/PT. How can I fix it?
A:
1.
Go into the System Control Panel, then click on Device Manager, and then find your CD/DVD
-ROM drive(s) and hard drive(s). Go into each one, c
lick
on Settings and check DMA. This enables UltraDMA.
2. Make sure that Video BIOS shadowing is disabled in your BIOS.
3.
Make sure that your
MVGA-NVG11A/P
/AL/AT/PT card is not sharing any
