The monitor should be listed as Generic PnP Monitor or Generic Non-PnP Monitor. Then use CRU to add the resolutions again. If the monitor is Non-PnP, download CRU 1.0.1 to edit it.Did this, was recognised as Generic PnP Monitor, rebooted, applied CRU settings, rebooted again. Games still not use the Detailed resolution refresh rate. They default to 100Hz (why 100Hz? because of the first entry in the Detailed resolutions?) and GPU still applies scaling (only for the 100Hz, 125Hz and 150Hz it doesn't apply any scaling).

I don't see why using detailed resolutions would affect other resolutions.This is how I've setup CRU now, all the resolutions that require 123Hz+ are in Detailed resolution list (except for the first as this defines the default resolution, which is 1600x1200@100Hz my default for desktop) : (08-24-2013 09:02 PM)ToastyX Wrote: There shouldn't be any refresh rates other than the ones you add.There aren't any other than the ones listed by CRU (including the Established resolutions and their respective refresh rates) edit: When having 1024x768@150Hz in Detailed resolutions and having 1024x768@120Hz in Standard resolutions it will not force 120Hz in games. When having 1024x768@120Hz in Standard resolutions only it does not force 120Hz in games either. So it seems I was wrong in the first place about Standard resolutions forcing refresh rates, sorry about that. I guess 100Hz and 120Hz are enabled for 1024x768 because of the 1600x1200@100Hz first Detailed resolutions entry? And that's why it defaults to 100Hz for those lower resolutions? edit2: I tried removing the 1600x1200@100Hz as first entry, adding it to the Standard resolution list, and having 800x600@160Hz as the first entry in Detailed resolutions now, so the highest refresh rate is listed first. This still does not force refresh rates for the lower resolutions, it keeps defaulting to 100Hz and applying scaling, it seems it keeps my desktop resolution 1600x1200@100Hz and centers the picture when I run a game (where I can't select a refresh rate) at 1024x768. I wonder how to solve this? If at all possible with CRU? edit3: After setting my desktop resolution to 1920x1440@85Hz just for fun, then running a game in 1024x768 it does use 150Hz and no scaling?!?!?!?!? After further testing it seems that when my desktop resolution is using a refresh rate that >= 100Hz, it uses 100Hz and applies scaling, anything < 100Hz it will use the refresh rate as listed in CRU and does not apply scaling. After testing the above while I re-added 1600x1200@100Hz as the first entry in Detailed resolutions it always uses 100Hz and applies scaling when launching a game in 1024x768... Is this really a driver bug then? I'm lost now edit4: This seems to be the cause for my scaling problem: (08-24-2013 09:02 PM)ToastyX Wrote: Usually GPU scaling will apply to any resolution that's not listed in the EDID regardless of that setting.My question on this regard: is there a way around this? Or I just have to find a way to force any resolution to always use its maximum refresh rate. |
