Cant get resolution over 1920x1080 with intel HD graphics 630

[AGama5]

Hi. I have a lenovo ThinkVision Pro2840m monitor (4K) and can't get it to display over 1920x1080. I'm using a "High Speed" labeled HDMI to HDMI cable, latest 630 graphic drivers installed, etc. Attached log from Intel's Utility.

I would try a better quality HDMI cable, preferably one that is HDMI 2.0-compliant.

Thanks for your reply. I already have a HDMI cable that is supposedly 2.0. Link below

The HDMI connector on your motherboard supports only a very basic HDMI 1.4 connection. You should, in theory, be able to get a 4K@30Hz connection, but that's at best and the stars align. If they've implemented it properly on this motherboard, there should be a DisplayPort 1.2 connection available through the USB-C connector on the backplane. This would be capable of supporting 4K @ 60 Hz if it has been implemented properly. You would need a good USB-C-to-HDMI dongle to achieve this.
