Dell AW2721D: monitor drops the image, black screen randomly happening
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: 1. Image OK with backlight ON 2. 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.
