Acer Predator XB321HK, reboot loop, and after cycling through red green blue

Patrik1

Hi,

My Acer Predator XB321HK monitor suddenly got stuck in a reboot loop.

After disconnecting power cable and holding power in for 30+ seconds as recommended to power cycle it it's now stuck in some test mode after reconnecting power and starting it up.

It keeps, cycling between red green and blue colors full screen. I can't seem to get out of it even after full power cycle again.

Tried connecting it to a couple of different computers, both PC and Mac, using both HDMI and DP. No difference.

Any help appreciated

Hi @Patrik1,

Monitor self test,

1. Power OFF the unit.
2. Unplug all the cables.
3. Press and hold the power button for 30 seconds.
4. Turn ON the unit and check.​
