Check if the display shows no signal via DisplayPort, yet works with HDMI.
You've recently switched your GPU and experienced display issues. The monitor seems to work intermittently, and you're trying different cables. Consider checking the cable connections carefully, ensuring they're secure. Also, verify that your monitor's settings match the GPU's specifications—especially the DP version 1.2. If problems persist, try a different HDMI source or consult the manufacturer for compatibility guidance.
It seems the display port worked fine with the RX570. The issue might have been with the cable, which you assumed was outdated.
It seems related to the GPU. A brief search online and a look at a Reddit thread confirm DP works backward across versions, with 2.1 supporting 1.2 and 1.4, and vice versa. It could involve the DP port on the GPU. One person advises disconnecting everything temporarily.
