ATI scaling issue greyed out options.

[AbRASiON]

Hi all.

I'm trying to run BF3 in 1920x1080 on my 30" Dell (2560x1600) I would like the black bars to appears.
I'm using the displayport cable and I've done a fair bit of googling.
This thread doesn't help.

The option is under "Digital Flat-Panel" section of the drivers and it's called "Image Scaling" - it has options for "Enable GPU scaling" "maintain aspect ratio" "scale image to full panel size" and finally "use centered timings" - these are greyed out when I'm at 2560x1600 (windows)
Even if I drop to the desired in game resolution in Windows (1080) it still shows without black bars and the 3 sections are greyed out.

I've done some process mon hunting around and discovered this section
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Configuration\DEL4065PH5NY13N274L_0C_07DB_1E^25AE45A8C91AB212A6A8734E4B8D52C3\00\00
(obviously "DEL4065PH5NY13N274L_0C_07DB_1E^25AE45A8C91AB212A6A8734E4B8D52C3" is unique(

There's a DWORD in there which is set to "4" for scaling - which is the one I want - but I believe scaling just turns itself off when not in low resolutions :/
Infact the only way to turn scaling to mainain aspect ratio is to drop to 1280x960 but then it forgets when I go back
(Registry key stays correct at 4 - it's no longer changable :/ however it's 4 - doesn't work though)


Is there a solution to this? It's bloody annoying and frankly, poor design. I want to ALWAYS remember my maintain aspect ratio settings, or configure per resolution. I don't think this has good enoguh controls for me to configure it properly.

I've put enough keywords in this that google might find it, I was tempted to post to AMD / ATI forums but I just can't be bothered, I'm not holding my breath. Worth a shot here though, appreciate your time guys

- thanks

For what it's worth, I have to be in non-native resolution for the option to select scaling methods to not be greyed out.

I seem to recall the option stopped working for me once, and after clean uninstalling and reinstalling the drivers for a different reason it started working again. You might want to try that, using some program that cleans out all the registry entries or finding and deleting the Catalyst registry entry in HKLM\SYSTEM\CurrentControlSet\Control\Video before reinstalling drivers.


Or try disconnecting and reconnecting your monitor while Windows is running, forces it to reassess your monitor and sometimes clears up stupid stuff like that.

I'm having this issue. I think it was due to a recent upgrade to Catalyst 11.11. This guy over at Tom's seems to be having it as well:
