Release 343 Graphics Drivers for Windows - Version 344.75 RN-W34475-02v01

Known Product Limitations

1280 × 1024 @ 60 Hz not Available on BenQ FP241W Monitors

Even though the monitor EDID lists 1280 × 1024 @ 60 Hz, the screen turns blank when

using an HDMI connection. This is an issue with the monitor and not the NVIDIA driver.

Because of this issue with the monitor, the NVIDIA driver blocks the problem mode (1280

1024 @ 60 Hz) and makes it unavailable.

GeForce 6 and 7 Series Cards Cannot Output Interlaced

Signals in SLI Mode [251457]

 Problem

Rendering problems and instability occur when outputting interlaced modes (480i,

576i and 1080i) over the Y Pr Pb component and DVI outputs.

 Explanation

This is a hardware limitation in SLI mode only and cannot be fixed via a driver update.

 Resolution

Due to this issue, starting in driver version 162.18 in Windows XP, the driver will

automatically disable SLI mode when using the 480i, 576i and 1080i modes over all

connectors on the GeForce 6 and 7 series GPUs.

To re-enable SLI mode, you must choose a non-interlaced output mode and reboot

your computer.

• GeForce 8 series GPUs do not have this hardware limitation and you can output all

HDTV interlaced and progressive scan outputs in SLI mode.

• The 480p, 576p, 720p, and 1080p progressive scan modes do not have this issue in

SLI mode and are not affected by this change.

Image Sharpening Control not Available with GeForce 8

Series and Later GPUs

With GeForce 8 Series and later graphics cards, the Image sharpening slider on the

NVIDIA Control Panel-> Display->Adjust Desktop Color Settings page is grayed out.

This control is intentionally disabled because image sharpening is not supported on

GeForce 8 series and later GPUs.

Display Output Selection not Available on “Bridgeless” SLI

On graphics cards that can operate in SLI mode without the SLI connector (such as the

GeForce 6600), you cannot select which monitor to display the output. On the SLI display

property page, the option box to select the output display is not available.
