Windows 7 Resolution problem with Win 7

[YaPaY]

Hello,

My Card is 9800 GT and my LCD TV is Toshiba AV500.

In XP:

I'm adding a custom resolution 1360*768 and timing CLS. (progressive 60hz). Almost every game work 1360*768 with 1:1 Pixel mapping and Great Quality. There is not any problem, everything works very well

In Windows 7:

I'm adding a custom resolution 1360*768 and timing CLS. (progressive 60hz). There is not any problem with my LCD TV. 1:1 Pixel mapping ok, I can use my LCD Tv as regular PC monitor, I can watch HD films with 1:1 Pixel mapping with 1360*768.

Life is very well, since the games.

About 5 months, I'm trying to fix this stupid problem. In Windows 7, when I start any fullscreen game (doesn't matter) with 1360*768 I can play only in window mode. If I click the maximize button there is always an error message "this resolution not supported by bla bla"

or,

I'm changing the resolution of game to 1360x768 and some games wants to restart itself. After restart the games converting resolution except 1360*768 and without 1360*768 the games seems blurry, aliasing, darker or worse. (no 1:1 pixelmapping)

But,

related game working in XP with fullscreen without any window, with 1360*768 and 1:1 Pixel mapping.

What is the difference Windows Xp and Windows 7. I have many many drivers already tried, I changed my TV's EDID information, I did many many tricks. I'm getting crazy. Please help, How can I fix this problem without XP install.

Thank you very much for your help and sorry for my poor English.

It seems like you are experiencing difficulty with running games in fullscreen mode at a custom resolution of 1360x768 on Windows 7 compared to your experience on Windows XP. This issue might stem from differences in how Windows XP and Windows 7 handle graphics and display settings. Here are some possible reasons for the differences you are encountering between Windows XP and Windows 7: 1. Graphics Driver Compatibility: Windows 7 may have different driver requirements or compatibility issues with your graphics card compared to Windows XP. Make sure you have the latest graphics drivers installed for your NVIDIA GeForce 9800 GT that are compatible with Windows 7. 2. DirectX Version: Games on Windows 7 might require a different version of DirectX compared to Windows XP. Ensure that your DirectX version is up to date and compatible with the games you are trying to run. 3. Resolution Handling: Windows 7 might handle custom resolutions differently than Windows XP. The error message you are receiving when trying to go fullscreen could indicate that the game does not properly recognize or support the resolution you are setting. 4. Compatibility Mode: Try running the games in compatibility mode. Right-click on the game's executable file, go to Properties, and then to the Compatibility tab. Here you can set the compatibility mode to Windows XP and see if that helps. 5. Refresh Rate Settings: Check the refresh rate settings for your custom resolution in Windows 7. Make sure the refresh rate matches the specifications of your Toshiba AV500 TV. 6. EDID Information: You mentioned that you have modified your TV's EDID information. Ensure that the modified information is correctly recognized by Windows 7 and the games you are trying to run. Since you have tried many drivers and tricks without success, here are a few more steps you could consider: - Check Game Settings: Some games have specific settings related to resolution and display. Make sure you have checked the in-game settings to see if there are options that could be affecting the display behavior. - System Restore Point: If this issue started occurring after a specific update or change, you can try restoring your system to a point where the games were working correctly. - Graphics Settings: Experiment with different graphics settings within the games to see if adjusting options like anti-aliasing, brightness, or contrast helps improve the display quality. These are some general troubleshooting steps to help identify the difference between Windows XP and Windows 7 in handling custom resolutions for games. If the issue persists, you may need to consider reaching out to the game developers or seeking assistance from a tech support specialist.
