GeForce2 Go incorrectly identifies native panel resolution

[Deipotent]

I have a DELL Inspiron 8100 laptop with BIOS A15 which originally came with an ATI Radeon 7500 64MB video card. Just as the 3 year warranty was about to run out this card went wrong, and was replaced by an ATI Mobility Radeon 9000 64MB card (as DELL no longer had any 7500 cards). Recently, this card appears to have gone wrong with the screen having lots of red flickering dots over the screen.

I have just purchased an nVidia GeForce2 Go 32MB card (part 04D597) to replace it, and after installing, the problem with the red flickering dots has disappeared, but the card incorrectly identifies the display panel as having a native resolution of 1400x1050, instead of 1600x1200. This results in display corruption on 200 pixels on the right-hand side, and 150 pixels on the bottom.

I have read that there can be some incompatibility problems with laptop video cards and certain display panels.

Is there any way I can fix this problem and get the card to correctly identify the panel as 1600x1200 ?

What LCD panel do you have? What driver versions have you tried?

Running NERD with a working driver (needs to be older one probably) should tell you the correct model.

In the meantime you could try the Dell SEC3255 fix here.

I have the Samsung Panel, and the DP/N is KR-02R290-39792-2AG-019T.

The problem is not driver related as the problem occurs during POST.

Just read the SEC3255 fix thread which looks promising. It looks like it will still have the problems during POST and boot, but should allow me to select 1600x1200 when in Windows.

OK, like Bill said, you'll have to use the Enhancer tool to make the suitable alterations to handle the SEC3255 [samsung UltraSharp LCD Panel] to the stock INF for your particular driver version. You'll then have to reinstall your Nvidia driver again, using this "modded" INF file instead of the stock version from Nvidia to apply the fix (you copy it into the folder where you have unpacked the drivers files, overwriting the old INF). Hope that helps. :)
