Hello,

I bought the AW2721D 2 weeks ago.

I noticed that the screen randomly looses the image, suddenly the screen goes black (but the screen power is ON). The backlight of the screen stays on. The complete sequence is 

Image OK with backlight ON -> No image with backlight ON (you can see it because of IPS glow), and the OSD is not appearing using buttons on the monitor;

When it's happening, the screen does not respond, it's impossible to use the buttons on the monitor to display the OSD to change input or display informations for example.

The only way to get the image back is to turn off the screen, and turn it on again.

I've been experiencing this on:
- Windows 10 1440p (240hz) using a DisplayPort cable while gaming
- MacOS BigSur 1440p (144hz) using HDMI cable while working

The firmware on my screen says it's M0B101.

Do I have a defective unit ? My friend who bought the same screen at the same time on the same reseller (amazon.fr) does not have this issue.

I doubt that the power cord is the reason this is happening because the backlight stays on. Any loss of power would translate in no power at all (no backlight) for a short amount of time. This is not the case for me.
