I hear you. It happens both with the intel driver and with the standard 'modesetting' driver. Quite a few people appear to have this problem from what I could glean out there. I understand the reluctance at this layer to look into this, but it is a fairly common problem, and I get the impression wherever I see this reported that there is no-one even trying.
I am not blaming anyone here. I was simply hoping for a bit more help than passing this off as some other group's issue. I have probably already spent 12h+ with many attempts to bypass this, trying different monitors, modelines, looking for newer intel driver versions, switching to and fro between the intel and the standard driver, overriding edid info, different HDMI cables, different kernel versions (as far as I could get them). I have run out of ideas and lost *a lot* of sleep. Thanks. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1793837 Title: xorg gives low resolution on HDMI port Status in linux package in Ubuntu: Confirmed Bug description: This is a Zotac CI547 box. It has to video outputs: one HDMI and one DisplayPort. The HDMI port appears as DP-1 in the logs, the DisplayPort as DP-2. The hardware is Intel HD 620 and is allegedly able to run two displays simultaneously at 4K. I have one WQHD monitor (=2560x1440) and I get that full resolution over the DisplayPort. However, I would like to also get that resolution over the HDMI port (in order to connect two identical monitors), but over HDMI I only get 1024x768. Updating the kernel to the latest 4.18.8 using UKUU made no difference.
