I just got a Dell 43' 4K monitor, P4317Q. On my Mac Pro, it shows 3,840x2,160 resolution. But on the monitor, it shows only 2160p. The text on the monitor is not sharp either. Previously, I had a Philips 40' 4K monitor. It showed 3,840x2,160 on both sides.

Nov 19, 2017 No, it's a DisplayPort feature. It's called MST. You either need displays with a DisplayPort output or an MST Hub. Bandwidth is limited to the normal amount so it's not possible with email protected displays on DisplayPort 1.2 and you can only connect two of them to a DisplayPort 1.3/1.4 output. Lower refresh rate or resolution displays can have more connected, so you can do three.
What should I do to increase the resolution on the Dell monitor? I use a DisplayPort to mini-DisplayPort cable to connect them. I switched to a HDMI cable and the problem is still the same.
My Mac Pro also connects to 2 Dell 1,920x1,200 monitors. These two monitors have worked fine. Any pointer on how to fix the 4K monitor problems would be greatly appreciated.
