Bought this for my up and coming Mac Pro which won't be here for another couple months. Works on my late 2013 13" rMBP at 3840x21 Bought this for my up and coming Mac Pro which won't be here for another couple months. Works on my late 2013 13" rMBP at 3840x2160x30Hz as advertised, but also shocked that my Mid 2011 27-inch iMac, not advertised as able, is actually driving it at this same full resolution & refresh rate (with AMD Radeon HD 6970M 1024 MB) using the DisplayPort cable that came with the display. Slightly slow and jumpy, but the resolution is full and legit. Text looks better when display installed upside down as the subpixel text rendering expects the pixels to be divided R-G-B and this monitor has it reversed, B-G-R. Until OS X supports B-G-R natively, the included stand allows upside down mounting and then simply rotate it 180 degrees in system preferences. …

Absolutely the best overpriced item I have ever bought. The colors are brilliant and come as close to my prints on my Epson photo Absolutely the best overpriced item I have ever bought. The colors are brilliant and come as close to my prints on my Epson photo printer as no other display I've used before. It definitively beats any Apple display (including "Retinas"). Mounting and setup was a breeze. This is an absolute must have for anyone willing to spend the extra buck as an early adopter of new technology. I have also found the price Apple sells this item at to be decently competitive. …

2 X 4K on Haswell/Nvidia rMBP!!!
Just installed TWO Dell UP3214Q on a late 15" 2013 rMBP with discrete Nvidia GeForce 650m. Let's remember the Dell 4K, which has t Just installed TWO Dell UP3214Q on a late 15" 2013 rMBP with discrete Nvidia GeForce 650m. Let's remember the Dell 4K, which has the same IZGO screen.
DisplayPort 1.2 can be enabled on the Dell OSD.
On MacOS X Mavericks, the rMBP runs it's screen at full res @ 60Hz, the 2 4K monitors at full res but only @ 30Hz.
In Windows 8.1 in bootcamp, the rMBP runs it's screen at full res @ 60Hz, the 2 4K monitors at full res @ 30Hz refresh if DisplayPort 1.2 is disabled, but can only run it's screen and ONE of the 4k at full res AND 60Hz with DP1.2 enabled.
INTERRESTINGLY, if you "SOFT disconnect" the rMBP own screen it will then drive both 4K monitors at full res AND 60 Hz, WOW!!!
There you have it. The late 2013 runs 2x 4k screens at full res. …

Worked for almost two hours, then died.
I need an ultra-high res monitor that can rotate to vertical (portrait) so decided to try this one because Apple sells it for use I need an ultra-high res monitor that can rotate to vertical (portrait) so decided to try this one because Apple sells it for use with my new MacPro. Got it up and running horizontally (landscape) and used it for about two hours over a couple of days. Then decided to try it in portrait orientation as this is how I plan to use it most often. Set the screen on my Mac to 90 degrees then, carefully, smoothly, with no bumps or jarring, turned the monitor 90 degrees. Within five seconds the screen went blank and the green "power" light went out. I could not revive the monitor no mater what I tried (or Sharp tech support suggested). I did not have the monitor in an enclosure, just on top of a desk, so no chance there was overheating from poor airflow. The power cord was also plugged into a high quality surge protector. There is a slight hum when the monitor power switch is on, so I know power is getting to the monitor. I am exchanging it for the same model in the hope it was just a bad unit, but if the next one gives me a problem I will give up on it. I'm down for two weeks due to having to send this one back and wait for a replacement unit to be sent! I also hate that the stand only allows horizontal OR vertical mounting. The stand should be designed to allow users to rotate it 90 degrees as needed — not either/or. Also note that Apple told me I will not be able to use the monitor in its highest resolution until Yosemite is released sometime this Fall (wish I had known that prior to purchasing). Sharp sells a similar monitor with a multi-touch screen so one would think they would be more robust. It is a large monitor so it's a big, bulky package to try and get back in its packaging, tape up, and haul back to a UPS site. All-in-all a big hassle and inconvenience for a one-person business like mine to deal with. I wish Apple manufactured a monitor of equivalent resolution and size. I would have purchased it instead. …

Best Monitors that I have Owned
I ordered the new Mac Pro with two of these monitors. When I first turned them on I found that I had more real estate than ever be I ordered the new Mac Pro with two of these monitors. When I first turned them on I found that I had more real estate than ever before. These are razor sharp monitors. Yes, they perform wonderfully with my epson printer. Previously the gold standard monitors were my older 30" cinema displays. These new thunderbolt monitors, made by Sharp, are simply far superior. My Macbook Pro (Late 2013) also drives both monitors. Hot-swapping is a breeze. Just unplug one or both monitors. I often do this when I want to steal away them from my Mac Pro and use them with my laptop. Two of these monitors cost almost as much as my Mac Pro but their performance and real estate is well worth the price. These are beautifully crafted displays with stands that allow raising (quite high or very low) as well as tilting. Again... back to the 4K real estate. I have so much room to work now that it makes me hesitate to use any display system that is smaller. Now what will I do with my old Mac Pro and Apple Cinema displays? Thanks Apple. Your equipment is simply the best on the planet! …

Could be better
The first one I received failed after 2 weeks of use. A permanent vertical blue line on the left side of the screen showed up on The first one I received failed after 2 weeks of use. A permanent vertical blue line on the left side of the screen showed up on all inputs.
The picture, when working is great. This monitor has a lot of functionality of TV, but is missing a remote.
I don't know what Sharp was thinking not including a remote for this monitor since it has multiple inputs and a built-in speaker.
A remote for controlling switching of inputs, volume, menu, and on/off would be extremely helpful, especially if you have this monitor mounted on wall. …

Display Port - HDMI
- Asked by Scott B from Arlington
You can run a Thunderbolt cable to the Sharp 4k display (up to 3) or to an Apple 27" Monitor (up to You can run a Thunderbolt cable to the Sharp 4k display (up to 3) or to an Apple 27" Monitor (up to 6). You'll notice the the Mini Display Port connector looks the same as the Thunderbolt cable. I have read that the cables are not backwards compatible (you can't use a mini display port cable with a thunderbolt i/o). This leaves the HDMI free. You will need to purchase a Thunderbolt cable if you do't have one already as the only thing included in the box with the Mac Pro is the power cable.
