This is my first time using an AMD gpu so i've had some issues with it.. but managed to get things stable.. with some mild OC (AMD Adrenaline app) .... and was able to play FH5 for a period of time.
.
I was getting black screen issues on some game so i reinstalled the driver (23.11.1).. and I got this ..

Also, Windows menus looks blurry/washed out.

I went into the LG menu and changed the input to PC ..nothing changed

I've updated the TV software and ran all the diagnostics available on the LG website…I also went into the AMD software a tried everything from changing colour depth to pixel format

Note that I faced the same screen and changed the HDMI input (on the TV) and it was resolved .. but this time all HDMI.. give the same result... There was a brief moment when I used the HDMI behind the TV (never used it before ) and it gave a clear picture.. but there was an LG message on screen about HD settings and soon I pressed ok .. back came the pixelated mess...

Finally I brought another TV 4k 60Hz.. to at least see whether the TV or PC issue.. the second TV gave the same results..

On The device manager it says generic monitor.. so not sure if that has anything to do with it...

I'm not sure what to do next.. so your help will be appreciated

Here are some things you can try to troubleshoot the problem:

1. Check the HDMI cable:

Make sure you're using a high-quality HDMI cable that is compatible with your TV and graphics card. A damaged or low-quality cable can cause problems with the display, including blurriness and pixelation.

2. Try a different HDMI port:

If you're using an HDMI port on your TV that is not directly connected to the motherboard, try using a different port. Some TVs have HDMI ports that are designed for specific devices, such as game consoles or Blu-ray players.

3. Update your drivers:

Make sure you have the latest drivers installed for your AMD Radeon RX 7800 XT graphics card. You can download the latest drivers from AMD's website.

4. Disable any overclocking:

If you have overclocked your AMD Radeon RX 7800 XT graphics card, try disabling the overclocking to see if that resolves the problem. Overclocking can sometimes cause stability issues with the display.

5. Change the display scaling:

In Windows, go to Settings > System > Display. Under "Scale," try changing the percentage to something other than 100%. This can sometimes help to fix blurry or pixelated text.

6. Try a different monitor:

If you have another monitor available, try connecting your PC to that monitor to see if the problem persists. If the problem does not occur with a different monitor, then the issue is likely with your TV.

7. Contact AMD support:

If you have tried all of the above troubleshooting steps and the problem persists, then you may need to contact AMD support for further assistance.

Here are some additional tips:

1. Make sure that your TV is set to the correct input mode.
2. The input mode should be set to "PC" or "DVI."
3. Try resetting your TV to factory settings.
4. This can sometimes fix problems with the display.
5. Make sure that your TV's firmware is up to date.
6. You can check for firmware updates on the TV manufacturer's website.

I hope this helps!
