Windows 7: W7 Misidentify Native Resolution

W7 Misidentify Native Resolution

(If this has already been solved, please send me a link. Thanks!)

Okay, I've seen this problem discussed all over the Web in various forms.

My problem is that Windows 7 is incorrectly identifying the native resolution of my 22" wide screen, 16:10 monitor.

I have a NVIDIA GeForce 9500 GT and a Sceptre X22WG-1080p 16:10 LCD with a high resolution of 1680 x 1050. It was running perfectly on Vista 64-bit. I upgraded to 64-bit Windows 7, and Windows 7 insists my native resolution is 1920 x 1080. I am using a DVI to DVI cable, the same I used with Vista. When I set the resolution to 1680 x 1050, which I can do through Windows 7 settings, the screen shrinks and is bordered by black bars on either side.

I have the most up-to-date drivers from NVIDIA ( 191.07_desktop_win7_winvista_64bit_english_whql ), however this does not correct the problem. I've also used the NVIDIA control panel to change the resolution to 1680 x 1050, but I get the small screen with black bars on the sides.

I've manually installed the older Vista NVIDIA drivers, but this does not fix it either. I also tried uninstalling the monitor to see if Windows 7 would find it and properly identify it.

Over on the the NVIDIA forums (which are down at the moment) they may have found a patch. You have to modify the .inf file in the driver setup files.

In order to do so, you have to write in the four hex numbers of your monitor EDID. I have my EDID information, but I'm not sure how to fid the hex numbers. Here's the info. Any help would be appreciated.

Any help or suggestions would be greatly appreciated. Thanks!

EDIT: Oh, but I should also say that I'm concerned that Monitor Asset manager says my native res is 1920x1080 as well. My 22" Sceptre definitely has a native of 1680x1050. What's going on here?

Thanks for the link. Someone on here just posted new drivers for NVIDIA that are hot off the press. The Windows 7 64-bit one worked perfectly for me!

TechConnect Magazine - Nvidia delivers the OpenCL-ready GeForce 195.39 beta driver

Hopefully everyone else experiencing NVIDIA/Windows 7 widescreen problems will have the same results I did.

Check device manager for the driver date/version of video card. Which is it?

Why can't you select 1680x1050? Is it missing or what is stopping you?

Try changing the refresh rate to 60 Hz first in advanced settings, monitor tab. Then see if higher resolutions are available.

If you are still having problems, check out solution somewhere in the middle of this thread.
