    find "bottleneck" for screen resolution

    Hi, I've an somewhat unusual problem. According to specs my current onboard gpu supports up to 2560x1440 px screen resolution, but only for the HDMI port (Asus H170-Pro), DVI is limited to 1920px. My monitor supports up to 2560x1440px too - but only via DVI-D (Dell U2713HM) and HDMI is limited to 1920px

    I managed to find a HDMI to DVI cable thats supposed to support up to 4K (Amazon Basics so it shouldn't be scam) but still Ubuntu only offers me a max resolution of 1920x1080. So obviously someone is "lying" about their capability - is there any way to find out where the bottleneck is? Can I somehow see what capabilities the different devices are reporting? Or do you see any other chance to get this unusual setup to work at max resolution?

    Actually is via Dual LINK DVI or DisplayPort only.

    True - but are there single Link cables supporting 4k resolution? I was under the impression that everything higher than 1920 has to be Dual Link...
