RX 5700 XT GAMING OC 8G (2.0) resolution lock at 640x 480p with hdmi.
I bought a video card 3 days ago, installed it, it boot. Installed the drivers and everything worked fine.I use TV like monitor. In the program from amd in the display, you can see your connection adapter, I have hdmi (amd radeon rx 5700 xt). But after rebooting the PC, the video card sets the resolution lock at 640x 480p. And now the display is ddc display-dvi-d (amd radeon rx 5700 xt). After uninstalling the driver using DDU, I have no signal from hdmi. More problems: There is no image of the BIOS loading. There is no image of loading windows. There is no signal and after that the account and desktop are already loaded.
And after all, i can't see image from monitor only no signal. Now i need reinstall windows with clean install and then video card give signal.
I use Adrenalin 2020 Edition 20.11.1 Optional and Adrenalin 2020 Edition 20.9.1 Recommended (WHQL) same result.
On gtx 1060 3g everything works good and no problems.

Please don't write like "try dp port", my tv don't have display port. If gpu have hdmi port why he not work well?
