Hello everyone! I have a problem connecting my Macbook Air and this monitor, I use a Mini DisplayPort - DisplayPort cable. The laptop recognises the monitor, but it shows a black screen and the words "no signal". I then connected the laptop to another monitor (with the same cable) and everything worked. To test the functionality of the new monitor, I connected another laptop (HP Elite) via DisplayPort cable. Does anyone have an idea how I can solve the problem? Many thanks in advance!
