Also:
1 - Stop and Disable service: AMD External events utility
2 - Ensure that the Windows advanced display option is enable: "hide modes that is monitor cannot display"
That indeed helped! Thank you very much, would have never found this service thing!!!
Unfortunately retroArch still wont work as it should. I've tried a lot of different options but never get the switchres to work properly (i have the needed super resolutions installed, no worries).
So what happens is this; if i try the video driver "gl" or "d3d12" it stays in the menu in 480i but then when i launch a game it only shows this tiny strip (see screenshot). This also happens when i use the "rgui" which i would prefer to the x-thing.
if i set the video driver to d3d9, d3d10, d3d11 it also works on the crt but stimply stays in 480i and doesnt swtich the resolution like for intance groovymame would. I think im really close now soo please help! if anybody knows the issue.
EDIT: ok, the problem was i didnt set the aspect ratio to custom, no i got 480i all over but not the real switch res but hope will figure that out too soon
so if anybody knows on what to set
custom_viewport_height
custom_viewport_width
correctly, help would be appreciated! if i set it to 640x480 the games use just this resolution but dont switch to super res.
