The other LG I've had which were 1440 just had problems you would not want to deal with.

My overall favorite is the LG 31 inch 4k. Does not overwhelm when sitting looking at things on the display, it fits nicely.

Thanks so much for posting an explicit "this works" for a monitor. I'm replacing a failing 30" Cinema Display and I have learned that many decent monitors have issues with the Mac Pro (late 2013), such as not coming back from Sleep, etc. Delighted to find your experience shared. Thanks!

Side note: the LG 31" digital cinema monitor is a true DCI 4K resolution (4096 x 2160) but I believe the Mac Pro cannot display any screen beyond UHD (3840 x 2160). Can you shed any light on that issue? I'm interested in being able to do the DCI 4K but it's not a deal-breaker at the moment.

it pretty small but does full 4k.
