It seems like you are facing an issue with your screen resolution settings on Windows 7 Ultimate 64-bit with your ASUS P5KPL-CM system. The black border appearing when you set the resolution below 1280x1024 and the full-screen issue in games are common issues that can be resolved through proper configuration settings. Here are some steps you can take to address these problems: 1. Check Graphics Driver Settings: - Confirm that you have the latest NVIDIA drivers installed. You mentioned version 190.62, but it's good practice to double-check if there are any newer versions available. - Open the NVIDIA Control Panel to ensure that the driver settings are correctly configured. Sometimes, certain options might be hidden or need to be enabled. 2. Adjust Scaling Options: - Since you mentioned the "NVIDIA flat scaling option," it's possible that the scaling settings are affecting the display. Look for options related to scaling and display settings in the NVIDIA Control Panel. - If the "Flat scaling" option is not available in the Control Panel, you can try adjusting other scaling options to see if that resolves the issue. 3. Monitor Settings: - Check the settings on your Samsung SyncMaster 732NW monitor. Ensure that the monitor is set to the correct input source and resolution matching the Windows settings. - Verify that the refresh rate is correctly set. While 75Hz might help with the full-screen issue, it's essential to ensure that all settings are synchronized. 4. Game Settings: - Within the game settings, look for display options that relate to resolution and scaling. Adjust these settings to match your monitor's resolution. - Some games have specific display settings that might override the system settings. Make sure to check and adjust these accordingly. 5. Compatibility Mode: - You can also try running games in compatibility mode. Right-click on the game's shortcut or executable, go to Properties, and under the Compatibility tab, check the box for "Run this program in compatibility mode for" and select an earlier version of Windows to see if that helps. If after trying these steps you still encounter issues, feel free to provide more details or screenshots of your NVIDIA Control Panel settings for further assistance.
