Hello,
I’ve recently bought an ultrawide monitor (Huawei MateView GT 34 - 34”, 3440x1440, 165hz) and I have a problem connecting it to my graphic card.
I have an old Gigabyte R9 280x, that has 1 dvi port, 1 hdmi port (1.4a up to 2560x1440 with 60hz) and 2 miniDP (1.2 up to 4k). So, in order to have the maximum resolution i bought a MiniDP to Hdmi adapter (it support up to 4k@30hz. Product link: https://www.hama.com/00200332/hama-video-adapter-mini-displayport-plug-hdmi-socket-ultra-hd-4k ) and connected through an hdmi cable (i know that i’ll get only 100hz this way, but I didn’t find a good miniDP to DP cable right now).
The problem is that, even that i connected the monitor to the graphic card through adapter, i still get only 2560x1440@60hz max resolution no matter what i do. Can you give me some suggestion what can i do?
Many thanks
Ps. I tested the HDMI cable with my laptop that has a 2.0 HDMI and connected it to the monitor and i get 3440x1440@100hz, so the cable is not the problem

No, no, no. Try to avoid using video adapters with active signal conversion, when possible.
Your monitor has DisplayPort input. Use miniDP to DisplayPort cable.

If you can't get miniDP to DP cable, then get miniDP to DP adapter plus regular DP-DP cable.
