AW2720HFA, 239.76Hz highest rate, goes black
Around 3 months ago I bought this monitor and it worked fine. But when I tried to enable 143.98Hz the screen kept on going black randomly for a few seconds. Luckily, this has stopped. But when I try to enable 239.76Hz (the highest refresh rate the monitor can do) the monitor just goes completely black, but it is still turned on. When I turn it back to 143.98Hz on my second monitor, the AW2720HFA goes back to normal. This is really annoying, so does anyone know how to fix this?

Try with a DP connection and see if you still get the issue.

It uses a HDMI cable that is plugged into my GPU (rtx 3080)

According to the manual it comes with a DP cable: DP cable
I would check the box, it should be in there. If it's missing that document shows how to contact Dell about missing components.
