Cannot select 1920x1080 resolution anymore!

Hi everybody,

A few days ago, I bought a new system (Core i7 930 / nVidia GTS-250 1GB Twin Frozr / Acer S24HL display, 1 SSD hard disk and 2 normal hard disks). After (quickly) installing Windows 7, all went well and I started to work/play with my new toy.

The SSD disk was connected as the last disk, which resulted in Windows 7 being installed on the SSD, and an additional 100Mb being reserved on the first disk (Samsung non-SSD) by Windows. Still no problems. I've done a bit of work, and enjoyed playing some games in 1920x1080 resolution. I wanted Windows to be completely installed on the SSD, however.

When I booted my machine yesterday, I noticed that my resolution had changed - wanting to install anyway, I didn't take any notice of it, switched the hard drives and reinstalled Windows 7.

Since then, I haven't been able to select any resolution over 1600x1200 (which looks crap on a HD screen unfortunately). When I want to change my resolution, Windows tells me I have a "generic non-pnp display", and doesn't allow me to go over 1600x1200.

Here's some stuff I tried/noticed:
- The monitor is connected via a simple VGA cable, but I doubt that's the problem, since it was working fine for two whole days.
- I've installed/updated the drivers for my motherboard, my graphics card, but not my display (Acer doesn't have any Windows 7 drivers for this screen).
- The Microsoft site tells me that my screen is 100% compatible, and that no additional drivers are needed.
- I've found countless articles on the internet by people who faced the same problem: I even used PowerStrip to create my own driver (which didn't work, Windows wouldn't recognize the driver).
- I've tried going into the device manager, deleting the display adapter, but Windows insists it can only find the generic non-pnp screen.

I'm at a loss as to what I should try next - if anybody can help me out with this problem, I'd appreciate it very much!

Thanks in advance,

Marlon

I know of this article which explains how to fix the problem with a Intel graphics card. After finding the DTD with MonInfo, go to where it explains how to fix problems via the registry. It should be easy enough to do it from their if your video card allows you to put in custom DTDs. Also, make sure the registry values are actually for a DTD, and not just have "..dtd..." in the name. Hope this helps. It solved my issue with my video card.

Thanks Petey7, but after reading the article you mentioned I'm afraid I have some doubts, since my chipset doesn't match the ones listed.

Welcome to Seven Forums. Have you tried going into control panel>nvidia control Panel>select change resolution>add resolution>check mark the add resolutions not exposed by display>click the creste custom resolution set to 1920>1080 refresh rate 60 hz>color depth 32 test it and see if it works.

Thefabe - you've just saved my day

I didn't even realise this was possible, but after checking and adding the resolution as you described, my monitor works like a charm at 1920x1080!

Thank you very much!
