Mac OS X does not show that clearly, but the Sharp OSD showed DisplayPort: MST.ītw. I checked in the Berlin Apple Store, and it looks like the Mac Pro is driving the Sharp PN-K321 using said MultiStream. At 60Hz - 30Hz everything is a bit laggy, the opposite of “snappy” … :-/
The logical choice is exactly as retina iPhone, iPad or Mac to draw all UI elements twice as large. At 1:1 of the native resolution everything is forbidably small. Yes, the display has exactly two times the regular pixels of a 24″ display. The hidpi resolution is only 1920 x 1080, correct? Is the native resolution too small to read text or adequately see the UI elements? Would editing code at that res be blinding? Looks like 4th gen Intel graphic should be capable on the hardware level to support 4k 60Hz: Please let me know of your setup goes, and in case of I can post screenshots, too. That reminds me also: My plan was also to play with this timing to see if I could get at least some 35MHz refresh for now by adjusting the timing closer to 300 MHz, but as this required a reboot, doesn’t work cycle I gave up on that for now, … The 300Mhz mode of the two does not work here, only the 267.75 MHz one (click on the eye icon for detailed timing info).
I just remember there where two 3840×2160 entires which are named: 1080p (NTSC) (HiDPI). Thanks.īut you are at 3840×2160, just not HiDPI? Let’s hope Apple will support the Dell LCDs soon without any hackery. It only comes up with “Not activated - invalid?” Will have another look then. I tried SwitchResx but I cannot get it into HiDPI mode with 3840×2160. Hmm… I have access to a mid-2012 rMBP 15″, too. Needless to say that the lack of proper 4K support on latest Macs and HiDPI without tricks is really a bit disappointing. PS: you could try not enabling DisayPort 1.2 in the display menu, or vice versa, …
The NVidia and Intel driver may behave different though, …įor HiDPI I used the demo version of SwitchResX to trick OS X into the 2x scaling HiDPI more. Well, I have a 15″ with NVIDIA GeForce GT 650M, the 13″ only has Intel “Iris” graphics, … Though I think at least via the HDMI port 30Hz at 3840-by-2160 should be possible on your machine, too … Working on a late-2013 rMBP 13″ here.Ĭan you elaborate on what you did exactly so I might have a chance to get the same results?! :-) I got mine yesterday and cannot quite get it to work at an acceptable resolution.

PS: 16:9 really is annoying for work, 16:10 should be the standard for Pro work, and cinema is more like 21:9 anyway, …
However, on these, and even the later Retina MacBook Pro it only runs the full 4k resolution at 30 Hz. Even my not so recent mid-2012 Retina MacBook Pro. Just a quick note: The affordable, and color accurate 24″ 4K display from Dell (UP2414Q) does work on recent Macs.
