Monitor just arrived today. It is supposed to support up to 2560×1440 resolution, but it only displays low resolution (1920×1080), and xrandr shows that as the only available resolution.

It is connected to a BeeLink S-13 mini via HDMI cable (supplied with the BeeLink, which has only HDMI graphics ports). The BeeLink graphics does resolutions up to 3840 × 2160 (per product info). The BeeLink is a new machine. It is running OpenSuSE Leap 15.5.

How do I get this monitor to display full resolution?

    Which CB272U model do you have? There should be a bunch more letters after the U, or give us the first ten digits of your S/N. I believe they have all supported 2560x1440, but at different refresh rates. The N-150 CPU should handle 4K@60Hz, so dual 1440P should be within it's specs. Are you sure you have OpenSuSE set to allow the higher resolutions?

    Thanks for the reply. The letters are Ebmiiprx.

    Don't know about OpenSuSE settings - I'm used to it just discovering whatever hardware & display resolutions there are, and using the highest available. But all of them are either VGA or DVI connections. The BeeLink is the first machine I've had that is only HDMI.

    I'll see what I can find on Linux graphics settings. Also think I have a machine or two that have HDMI connectors (NVidia GPU cards…), so I can try with those.

    Refresh rate is not a big deal for me. I don't do gaming or video, so 60 Hz or even less is fine.
