I have been using this monitor for a few months now and absolutely love it. I am interested in putting it on an adjustable arm mount that clamps to my desk. Is this possible and if so, what arm mounts is/isn't it compatible with?

Asked by: HanB
Yes. I have 2 of these monitors on Ergotron LX Desk Monitor Arms. They are easy to mount and hold up well. That said, I have one monitor on a big, corner style desk which requires the arm to be fully extended and I notice the monitor shakes a little when I'm aggressively typing ;) Otherwise, for standard use, it works great.

Can I set quad screen and assign hdmi 1 to the screen 1, hdmi 2 to the screen 2 ? Works that way?

Asked by: Josias
I apologize, but no; according to the chart on page 25 of your owner’s manual, it is not possible to use both HDMI ports, at the same time, for the Picture By Picture (PBP) functions.
