UP2715K, Mac Pro, Strange split screen
Hi I'm running a Dell UP2715K on a Mac Pro (Sierra) through 2x Displayport, usually in 5K mode (2560x1440 HiDPI). Some of the software I'm using doesn't support retina mode though so in those cases I usually switch to normal 2560x1440 (non-retina). This used to work without issues, but now all of a sudden I'm getting a glitch when I do this. With ANY non-retina resolution that's 2560x1440 or smaller the monitor gets split in half and the left side has black borders and is scaled down while the right half is displayed correctly. See picture below. Anyone got an idea what the cause might be?

Unknown if the culprit is the Apple operating system, Apple drivers, or the UP2715K. Reset the UP2715K.
* Turn the UP2715K and the Mac Pro off
* Disconnect EVERY cable (including power cable) from the UP2715K
* Press and hold in the UP2715K power button for 10 seconds
* Reconnect all cabling
* Turn the UP2715K on, then the Mac Pro
* Once on the Apple OS desktop, restart the Mac Pro
* Retest. If the issue is still present, ask the Apple users on their Forum if they have seen the issue
