Calling all Nvidia video card owners!
Posted: 21 Nov 2006, 18:31
Hi everyone,
If you own a Nvidia video card and a widescreen monitor, I'd like to know if you've been able to get the "Fixed aspect ratio scaling" or "Do not scale" ("Centered output" in the classic control panel) options in the Nvidia control panel to work for you?
If you could post the following details your assistance would be greatly appreciated.
Video Card: Brand and model...
Driver: Version...
Operating System: Operating System, Service Pack, etc...
Monitor: Brand and model...
Fixed Aspect Ratio Scaling: Working / Not working...
Do Not Scale: Working / Not working...
I'd like to back from those of you who have, and haven't, got this working. In other words I'd like this thread to be an informal database of combinations that do and don't work.
Thanks!

My details:
Video Card: Nvidia 7600GT
Driver: WHQL 93.71 - 169.21
Operating System: Windows XP Professional, Service Pack 2
Monitor: Samsung 940BW
Fixed Aspect Ratio Scaling: Not working *
Do Not Scale: Not working *
* When I select either "Fixed aspect ratio scaling" or "Do not scale", then click "Apply", the aspect ratio of the picture on the monitor becomes distorted (i.e. expanded horizontally and / or contracted vertically). See photo (the settings in this photo are 800x600 and "Do not scale"). If I check the information section of the monitor's OSD, it says the resolution is 1280x1024.
From what I can tell, instead of drawing the lower resolution (i.e. 800x600) in the centre of the native resolution (i.e. 1440x900) and then outputting this to the monitor, the driver is drawing the lower resolution in the centre of 1280x1024. This is then scaled by the monitor itself to fit its native resolution (i.e. 1440x900), which results in the distortion.
To demonstrate...
In example photo A I've drawn a 800x600 red square in the centre of a 1440x900 image, then resized it to fit the original photo.
In example photo B I've drawn a 800x600 red square in the centre of a 1280x1024 image, then resized it to 1440x900, then resized it to fit the original photo.
You'll notice that in example photo A the red square doesn't match the picture on the monitor, where as in example photo B it matches it perfectly.
My assumption here is that this problem is caused by a bug in Nvidia's driver that occurs when using it in combination with a widescreen LCD monitor that supports a resolution with a greater number of pixels than the native resolution (i.e. where the native resolution is not the "maximum" resolution). My monitor has a native resolution of 1440x900 (1296000 pixels), but supports a maximum resolution of 1280x1024 (1310720 pixels).
