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&rsquo;s manual, it is not possible to use both HDMI ports, at the same time, for the Picture By Picture (PBP) functions.
