ASRock B450M Steel Legend DP isn't connecting properly, but HDMI functions correctly.
You're experiencing issues with the DisplayPort (DP) on your motherboard despite having a working HDMI connection. The problem seems to be specific to the DP interface on your board. Have you checked the motherboard documentation for any known DP compatibility issues or firmware updates? Also, ensure the GPU is properly seated and try connecting it to a different port if possible.
It looks like the problem resolved after updating Windows, which is unusual because the POST wasn’t showing issues before.
It might have been an earlier Windows update issue or a registry error. I’m not sure what all the updates do regarding resets or similar changes, but it seems to be resolved now. You could try creating a restore point just in case.
