But I cannot get any resolution higher than 3840x2160
I'm not able to create a custom resoultion of 7680x4320
On the TV I selected 8k resolution as well
I contacted AMD customer service ant they redirected me to the producer of the graphic card. The last message was to try another monitor, like the 8k monitors are hanging in trees
I tried CRU, I patched the graphic card with your amd patch, reset, and restart64
but I still donțt get the 7680p
What should I do to get 7680x4320 resolution as all the devices that I used are advertised that support this resolution?

DisplayPort 1.4 is limited to 1080 MHz pixel clock at 8 bpc and 1440 MHz pixel clock at 6 bpc. Anything higher requires Display Stream Compression (DSC), which the RX 480 doesn't support. In theory, setting the pixel format in the Radeon software to YCbCr 4:2:2 should allow 30 Hz to work, but I'm not sure how that translates when using active adapters. For YCbCr/RGB 4:4:4, the CTA-861 timing for 7680x4320 @ 30 Hz is 1188 MHz, so you would need to reduce that. "Automatic (PC)" will bring it down to 1030.42 MHz. Do not use the patcher. You will have to add a DisplayID extension block to add a custom 7680x4320 resolution.
