Does the LG Dualup monitor (28MQ780) work with Manjaro?

I am looking to buy this monitor, but I am concerned if the native SDQHD (2560 × 2880) resolution would work with my ThinkPad X1 Yoga (second gen) running Manjaro Linux.

Hi @pariahkite,

I do not see the it would have any problems. I have two LG monitors, 1 HDMI and 1 DVI, both running at 2560x1080 resolution.

As long as your computer has the necessary outputs for the monitor(s) and they’re working, I don’t see a problem.

Hope this helps!

Edit:

You don’t have to take my word for it, though. Here it is on the Xda-developers website:

https://www.xda-developers.com/lg-dualup-monitor-available-699-99/

So I’d say it’s safe. As long as your PC has the necessary outputs, of course.
