Hi all,


since I purchased my Samsung ATIV 8 notebook (870Z5E-X04DE, no touch panel) I've never been able to see all the usual options in CCC.


Especially the "My Digital Flatpanels" and the included scaling options are sorely missed. Until shortly, when I was still using a 16:9 screen (Samsung 2494HM), this was really something I could overlook. But since I've purchased a 21:9 Ultra-Wide (LG 34UM95-P), I can't ignore this issue any longer. The new screen doesn't seem to be the culprit, since this occurred already with the old one and there's no scaling/stretching in Windows when I lower the resolution.


Example (Mad Max):


While the screenshots maintain the correct aspect ratio and resolution (1920x1440), the in-game depiction on my screen looks like this (sorry for bad quality, I just took this with my phone)



As you can see, the resolution is stretched to panel size and, IMHO, looks quite horrible. The framerate tanks as well (~20 fps). But when I switch it to windowed mode and scale to the correct aspect ratio, it is easily playable (~50 fps). The mode the screen uses is 1:1.


I've tried so far:

-The proprietary Samsung drivers (latest version)

-Official AMD driver (via automatic and manual selection), multiple versions (14.4 to recent)

-Leshcat's Catalyst (12.x to recent)


All of these Driver installations were preceded by CCCleaner and DDU in safe mode. Even a OS reinstall and a new HDMI cable didn't help at all. Windows is up to date, no red flags in the device manager:

I've now been using ATI/AMD GPU hardware for nearly 25 years and never had an error this persistent/hard to diagnose. Has anybody a solution for this?


Thank you very much for your help.
