Hi, I would just like to share with everyone the solution that I have found for the black screen/no signal problem with the Radeon RX 480 video card. This might not work for everyone but it worked for me. The problem resided in the card over heating so I removed the heat sink and fan and replaced the thermal paste on the GPU and also changed the thermal pads on the memory chips. This made a drastic difference even when the card is idle. I also increased the idle and max temps to help cool off the GPU. No I can finally enjoy gaming in Forza Horizon 5 without getting black screened. I hope that this helps someone else , god knows that it's a frustrating problem. BTW this will void your warranty if you still have one. You do this at your own risk!!! Happy gaming all!
