Typing/generating display inf files to force refresh rates
Posted: Mon May 10, 2010 2:42 am
I'm trying to force windows (win7) think that there isn't available any refresh rate above 60 Hz.
Right now the display is not being detected deliberately because I need it to be that way, so it's using a generic non-pnp monitor inf file. But the native resolution of the display was missed at the nvidia control panel. It seems to be a frequent problem with win7 and I found at internet that a new inf file with the resolution I needed can be generated with powerstrip. It worked like a charm, so now I'm on the 'inf path' for solutions to problems with the display.
So, let's say that I want windows think that, for example, only two resolutions, both at 60Hz, are available and, as a result, only those two resolutions are listed at the nvidia control panel. In other words, I want to find a way to tell windows explicitly which are the resolutions available and their refresh rates.
Can it be done with an inf file? Do I need first to delete or cancel somehow the resolutions that are actually available? Are they stored at the windows register? Any resource with an explanation of the sintax of those inf files?
By the way, are there any alternative solutions?
