2 days ago I bought ed322QR monitor which works fine with both PS4 and my Dell laptop via HDMI. However, when I connect it to my Huawei Matebook 13 laptop it doesn't work. There's this dongle (Huawei Matedock) which I use for both Dell and Huawie laptops - HDMI for screen, USB receiver for mouse and headset are plugged there all the time and I just switch it between laptops. It works fine for Dell but doesn't for Huawei.
When connected to Huawei, monitor turns on, shows "no signal", turns off, turns on "shows no singal", turns off and so on (autodetection of source is turned off). When I go to display setting on my laptop it shows ed322QR there, if I extend screens I'm able to move windows to the other screen, also sound tries to go through screen as it's visible in sound settings. All drivers on laptop are up to date, same goes for Windows. I have another monitor at home (Dell) and it works perfectly fine with both laptops using the same dongle and same HDMI cable.
Anyone has any ideas how to fix it?
Thanks very much in advance!
