Win7 x64 Screen Resolution stuck @ 1600x1200

Hi people,

I've used x64 version of build 6801 and 6936 of Win7 and both of them worked fine for my daily works. Yesterday, I upgraded from build 6936 to the newly released 7000 build and afterwards I'm having problem with the resolution of my secondary monitor attached to my notebooks external display port. It worked fine with both of the older builds with the resolution 1680x1050, which is the recommended resolution for the monitor. I've had a problem with build 6801, however I could solve it by changing the monitor driver to a custom one I made using Rivatuner. This time nothing I've done has worked, so I would be happy if you can help me by sharing your experience.

I've tried following configurations with my Win7 build 7000 x64 and my NVIDIA Geforce Go 7600 display adapter:

1. Installed drivers from WindowsUpdate (with Antivirus software turned off), tried to change resolution, stuck at 1600x1200.

2. Changed monitor driver to a custom made with the resolution 1680x1050 defined, stuck at 1600x1200.

3. Installed 185.20 drivers from NVIDIA, using different monitor drivers, stuck at 1600x1200.

4. Edited registry keys at HKLM\System\Currentcontrolset\Control\Video with 1680x1050 resolution at refresh rate 60. Can see the resolution in Screen Resolution menu but when trying to apply it, stuck at 1600x1200.

5. Uninstalled all display drivers and installed drivers from NVIDIA and/or WinUpdate, stuck at 1600x1200.

6. Tried to create custom resolutions with unchecked "Hide modes that the monitor cannot display, tried to test the custom resolution of 1680x1050, it worked in older builds, but in build 7000, it even don't tries to test (no screen flickering) and gives "Custom Mode Failed" error, stuck at 1600x1200.

7. Create custom resolution with advanced settings and all timing options, same custom mode failed message without screen flickering, stuck at 1600x1200.

8. Installing older version display drivers from NVIDIA 170 and 180 series drivers, stuck at 1600x1200.

Anyone experiencing the same problem? Anyone knows what else to do? Since I've experienced the same problem with 6801 build and could get over it by changing the monitor driver, it is now strange, why this solution even not works for this build. Anyway, any help would be appericiated..

Thanks in advance!

I have not tried a clean install. I restored the backuped 6936 version and will try the update after installing 180.70 drivers from nvidia. Last time, before upgrade, 185.20 drivers were installed. I have read in some forums that 185.20 drivers have caused problems with already stable systems, so it is worth to try the upgrade again with another driver already installed.

At last, I have my backup handy, if the same happens again. And this time, I backuped also the registry keys under HKLM\SYSTEM\CURRENTCONTROLSET\CONTROL\VIDEO and will try to write them to registry if the same problem happens again after upgrade. I will write down the results I get after all this..

Updates (not so really):

- Made a clean install of Win7 bulid 7000 x64. No program installations made to be sure, just the updates from Windows Update and all not found drivers. Tried the 1680x1050 resolution with the driver came from Windows Update, no luck, still max resolution 1600x1200.

- Made a clean install (not again, just restored the clean backed up install with Acronis True Image Home ), installed 181.20 drivers from Nvidia, no luck, still max resolution 1600x1200.

- Made a clean install (restore to be honest), installed 185.20 drivers from Nvidia, no luck, still max resolution 1600x1200.

- In every condition, I also changed the monitor driver to a custom made, which has worked in Vista, and in builds 6801 and 6936, no luck, still max resolution 1600x1200.

Giving up on build 7000. There is a problem whether with the display driver system or monitor driver. (actually also changed the monitor driver files, with the ones in 6936, no luck, still max resolution 1600x1200.)

ANybody else having such an issue? Wanna share experiences, opinions? All comments very welcome!

Nobody using a Notebook with an NVIDIA Geforce Go display adapter and an LCD Monitor within a dual view extended desktop configuration and having the same issue with Win7 beta build 7000 x64??

 

After some search with google, it seems like, the resolution problem will stay as pain with dual or single monitors in systems using NVIDIA cards.

So, it make sense to know for all, if NVIDIA graphic card users with or without secondary monitor experiencing the problem about the screen resolution and not being able to use the native resolution of their monitors.

In all cases and all seems to be possible solutions, I've had no luck and the highest resolution I could get was 1600x1200. NVIDIA's control panel gives "custom mode test failed" error without even testing the resolution, if you try to test a custom resolution.

Shame that this problem wasn't part of the older builds and now with the public beta there it is..

PS: For the ones, that use older builds with succesfully native solutions of their monitors, please don't think that the upgrade will be ok without a problem, this has been done before and it ends in the same way!

OK people,

Since I feel to be the one that has done the most "test configurations" for this problem, I want to share another one with you. In the begin of this thread, I wrote a long article about what I've all done to solve the resolution problem with Win7 build 7000. Shortly after that, I have had a chance to test it in another configuration. The story follows:

My old configuration, with which I couldn't get above 1600x1200 resolution in Win7 build 7000 x64 was like that: Toshiba Satellite A100-912, Intel T7400 2.16 CPU, 3GB DDR2 RAM, Intel PM945 Chipset, NVidia Geforce Go 7600. And this configuration was not able to set the native resolution of my secondary monitor (1680x1050) with Win7 build 7000 x64 but the resolution could be set within the builds 6936 and 6801 (both x64).

The new configuration was like that: Samsung NP-R560, Intel T9400 2.53 CPU, 4GB DDR3 RAM, Intel PM45 Chipset, Nvidia Geforce 9600M GT. First I was afraid to install build 7000 directly as clean install, so I installed 6936 x64 and get the resolution working as I did in the old configuration. Afterwards and after making a whole backup of the working system, I upgraded to build 7000 x64. And guess what, the resolution was set without doing anything. The native resolution 1680x1050 was there in front of me.

Conclusion:

1. The problem may be related to the NVIDIA drivers. With Geforce Go 7600, I've used various drivers from laptopvideo2go website to get the resolution, but all failed even doing the test at the custom resolution management area in Nvidia control panel. BUT I haven't tested it with the drivers released from Nvidia for notebooks (179.28) since my old graphic adapter was not supported in the original inf and I tested the system before the offical release of these drivers. So, please be free to modify the inf of the nvidia's official driver for notebooks (179.28) and try to set the resolution and get back here with the results.

2. The problem may be related to the chipset. Since my old configuration was a PM945 chipset, which is pretty old, the resolution problem may be related to the chipset drivers or the chipset itself (the 945 chipset couldn't even address 4Gb RAM together). The new PM45 chipset may be the solution for this problem.

3. The system configuration or the codecs may be the real problem. Not every hardware works with every other one in totally peaceful and successful ways. Or even the codec related installations or the codec packages itself can be the cause of such problems.

What's next?

Waiting for your comments and possible configurations and test results. Please share them all..
