Trying to get setup using RSR on new graphics card, XFX Radeon RX 7600, but native display is detected as 1920 X 1080, so unable to use RSR to upscale graphics to 2160p for my display which is a Sony Bravia 4K LED television. I can play games such as FarCry 5 with the graphics at 3840 X 2160 @60Hz, I just apparently can't do it using RSR upscaling. Tried creating a custom resolution within Adrenalin but it keeps telling me my settings are incompatible with my display. Per the user manual I have for the TV which shows a diagram of a PC connected via HDMI to port 4 on the television that is what I am using. Per the specifications listed in the user manual for the TV all 4 HDMI ports support the same resolutions, including 3840 X 2160 at 60Hz, although there is a note which reades "YCbCr 4:2:0 / 8bit only." Tonight I purchased a HDMI 2.0 cable to confirm I wasn't using an outdated one.
Why is the native resolution being reported as 1920 X 1080 when I'm using a display capable of 4K, and is there any setting in the software that I can change to correct this? Would my custom resolution idea even help, and how would I set that up in a way that it wouldn't be rejected by the Adrenaline software? Is there any difference between the 4 ports on the back of the card, and is there a user manual available anywhere which identifies any possible difference between the ports on the back of the card?
Have Adrenalin 23.7.2 installed, and Windows shows the TV as a generic pnp monitor. Tried changing the latter to generic television but it immediately changes back, even in safe mode. Looking again at the 4 ports on the back of the card only 1 is HDMI, and that is all I can use with this TV. Exact model number of TV is XBR-55X810C.
