XB271HU only blue color displayed when refresh rate 60Hz and down

Hi

I've got a problem with my Predator XB271HU monitor.

Only the blue component of the image on the screen is displayed when the refresh rate is at or below 60Hz.

So when I started my pc this morning I've noticed the monitor splash screen/motherboard splash screen and everything was just blue (image seems fine but red and green are not there). But once windows started the screen was working fine.

Then I tried my Switch that is connected through HDMI and everything was blue (and black...) there too.

I had a hard time pinpointing what was causing this, because it works fine only in Windows: when I unplugged all cables save the power cord I have this problem with the On Screen Display too.

Then I thought of the refreshrate, and indeed when I change it in Windows 10 if I set it at 60Hz or below, only the blue color is displayed, but above 60Hz (85Hz, 100Hz, ..., 144Hz) the monitor works flawlessly.

I have tried another power cable, reseting the monitor via the OSD, but to no avail.

What are my other options?

Hi Placo,

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.
