This is from the Nvidia Control Panel Help:
1. From the NVIDIA Control Panel navigation tree pane, under Display, click Adjust desktop size and position to open the associated page.
2. Click the image that represents your flat panel display, or non-HD digital display connected to the HDMI, DisplayPort, or DVI connector.
3. Select Do not scale, then click Apply.
I'm able to follow steps 1 and 2. However, step 3 is not even displayed as an option for me. I'm using WinXP 32-bit SP3. My Nvidia Control Panel version is 2.8.254.08. Do any of you see step 3?
