4K monitor with 2013 macpro

[rueyloon]

Hello, what’s the current support for 60hz 4K on the macpro? I bought one when the 2013 just came out but it only supported 24hz so I returned it. Also what’s the best size for native 4K so the words won’t be too tiny? Thanks

I have a Dell P2715Q connected via mDP-->DP and it supports 60Hz on any resolution. I use the display default, which is 4K half (HiDPI that looks like 1920x1080) and I like the size of text and UI elements.
Edit: I believe for native 4K at least 32-34 inch.

I'm using a Dell 2415Q running at 3840 x 2160 @ 60Hz.

It's 24" and i feel this is a good sizing giving me retina resolution and everything feels just right.
Text an icons are about the same size as hd (1920x 1080) on a standard 24" screen (just a lot sharper).

The Mac Pro 6,1 should support 4K 60Hz back in 2013, just not the boot screen. If you boot the Mac with a 4K 60Hz monitor connected, then it may suck at black screen. But if you connect the monitor after the Mac boot to desktop, there should be no problem at all.

And Apple updated the firmware for Mac Pro 6,1 some time ago to make it support 4K 60Hz boot screen. It should be pretty flawless to run with 4K 60Hz screen now.

For screen size. If you want to run at native resolution. I personally suggest a 40” (110 PPI) display or above. For your reference, the 27” ACD has 109 PPI. Anything has higher pixel density will start to look very small in native resolution at normal distance. In fact, even on 27” ACD, I am not comfortable with the native text size. I have 20/20 eyesight, can read the text without issue, but has a tendency to sit closer and closer because everything is a bit small. I never have this problem when used the 1920x1200 94 PPI 24” ACD (or my current 82 PPI CHG90).

For HiDPI resolution, 27” 5k may be fine, because the extra pixels make everything a lot sharper, eventually, easier to read. But for non HiPDI, I really won’t suggest anything go beyond 110 PPI. However, this is very personal at the end. If possible, you better to go a computer store, and have a look and then decide what’s the max PPI you can accept without HiDPI.
