I have  lenovo ideapad z510 with both Linux and Windows. On both can't make the monitor work at WQHD. On the Linux I can't get it above 2560x1100, on the windows it is running at 2560x1300. With either running at 2560x1440 causes the monitor to display black screen. The HDMI cable is https://www.expertstommel-shop.de/TV-Audio/Fernseher/TV-Zubehoer/TV-Zubehoer/HDMI-Kabel/Hama-00056526-HDMI-Kabel-1-5-m-HDMI-Type-A-Standard-Anthrazit.html . I have tried updating the drivers to no success. It seems to me all the components should work - I think my laptop should support it, the cable seems fine, the monitor according to the specs should be fine. Yet I can't get it to work at WQHD. Any ideas what might be causing this?

    Edit managed to convince it to do 2560x1350 when I set it to 50hz on the linux but still not 1440

    Interestingly enough if i put it on 2560x1390 50Hz the monitor freaks out - every few frames the monitor essentially restarts
