Is this monitor suitable for my setup? I'm looking for a monitor for home office, very rarely amateur photo editing but no gaming, 21:9, still have IPS, HDMI connection (already have HP USB C docking station) and 34xx * 1440p resolution selected. But I don't know the brand at all. Has anyone here already had experience?

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!

Hello together Unfortunately, I can't manage to set the full resolution on my two Lenovo notebooks (T470s and V330-15IKB). More than the current 2560 x 1440 is not possible via UHD HDMI 1.4 cable, although according to the Intel graphics card 620 HD and 620 UHD this should be possible. Unfortunately, the notebooks do not have a Displayport connection. I have already installed the latest graphics drivers from February 2020. With this resolution, everything is much too big and uncomfortable for the eyes. What else can I do? Thank you for your support.
