1.0 out of 5 stars Doesn't really work at 4K 60Hz
Reviewed in the United States on March 1, 2014
Verified Purchase
This monitor ships in a broken state, and customers are left to hope that Sharp eventually ships a BIOS update to fix it.

The core problem is that the monitor is limited to 4K 30Hz with an ordinary DisplayLink signal. To achieve 4K 60Hz, the monitor's "Multi-Stream" (MST) feature must be enabled by going through its on-screen menus. The menu navigation experience is absolutely awful, with buttons hidden behind the panel and laid out in a counterintuitive arrangement.

When MST is enabled with the PC running, you can get into 4K 60Hz mode. However, I have yet to find an NVIDIA or AMD video card combination which enable this monitor to boot up at 4K 60Hz. Rather, you need to constantly be using the monitor's awful menu system to switch in and out of MST mode when booting to continue using the monitor.

What's worse, often the monitor loses sync when a screen-saver kicks in, requiring going through a reboot to get out of MST mode.

Maybe some day, Sharp will ship a BIOS update that fixes this problem. Until them STAY AWAY -- this monitor is unusable for its stated purpose of serving as a 4K monitor.

There is a giant discussion thread of users expressing these same woes here: [...]

2.0 out of 5 stars I want to love this monitor
Reviewed in the United States on August 26, 2013
Verified Purchase
Since this piece of hardware was announced, I was anxiously awaiting its release. The resolution and physical dimensions are great so I really wanted to love it. After a living with it for only a few months though, a major issue has become apparent. This monitor has the WORST problem with image burn in that I have ever seen. On an all black screen, you can clearly see the outlines of where application windows had previously been and make out the ghosts of text.

For approximately the last 5 years, my setup had been 2x Dell 30" 3008WFP monitors. I replaced one of those monitors with the PN-K321. The Dell screen, which has seen a similar workload and for a much longer period of time, has no problems.

I find the ghosting to be extremely distracting in my day-to-day work where I typically work with a full-screen, black-background window on the monitor. The problem is disappoint to say the least and, at this price point, unforgivable.

4.0 out of 5 stars Once you go 4k its hard to go back
Reviewed in the United States on May 10, 2015

I have two of these Sharp PN-K321 4k monitors along with a Dell 2407 HD monitor on my Windows 8.1 system. I'm using an Nvidia Quado K2200 video card to drive the 3 monitors I'm finding that they all work together fairly well. My video card seems to only be able to drive one of the K321's in MST mode to get the full 60P refresh rate. The other 321 is running at 30P (display port 1.2 SST mode) and the HD monitor is running at 60P. Current affordable video cards don't have the horsepower to run a pair of 4k monitors plus a 3rd or 4th monitor all at 60P. A M6000 might do it, but I'm not spending $4000 on a video card.

Let me state that I'm NOT running games or anything else that requires really fast video performance. Mostly light duty CAD work (in terms of video) and big spreadsheets.

I see that a previous reviewer stated that his monitor would get weird in MST mode. I find my system boots up and stays in MST/60P mode on the one K321 ok. About 10 seconds after the desktop appears on a boot up the screens all blank out for about 10 seconds while it appears my video card is trying to figure things out. Then all is fine. It did not do that when I had both of the K321's in SST/30P mode. I'm guessing this is more of a quirk of display port 1.2 in MST mode than the monitor.

I second the reviews that state the interface buttons on the side suck. Really hard to know what your doing, they should be on the front.

I'll also state that my second K321 seems to make a noticeable buzzing sound. The power supply brick is under the table, so its not coming from that. It seems to be coming from the back of the monitor. In a quiet room its noticeable, but with any ambient noise its noticeability fades away. My first K321 is perfectly quiet.

If you have the need and money to be an early adopter of 4k then I highly recommend this monitor. However it may be best to wait for the next generation of video cards and the next version of this monitor with HDMI 2.0.

5.0 out of 5 stars Ruined me for other displays
Reviewed in the United States on May 2, 2014
Bought this with the new (late 2013) Mac Pro and I'm ruined for other displays. Took a bit of fiddling to enable HiDPI on Mac OS X 10.9.2 (`sudo defaults write /Library/Preferences/com.apple.windowserver.plist DisplayResolutionEnabled -bool true`), and with the monitor's on-screen interface to enable 60 Hz, but once that was done, this is the best monitor I've ever used by far.

Edit: Mac OS X 10.9.3 fixed the HiDPI issue -- five Retina settings are now available in System Preferences with no Terminal futzing required.

1.0 out of 5 stars Dead pixel and inferior part used
Reviewed in the United States on April 14, 2014
Verified Purchase
I can't believe Sharp would ship this $3k monitor with dead pixels. This is totally unacceptable!
One of the base mounting screws head snapped off during initial assembly. I didn't even get a chance to tighten it and it just snapped. I couldn't even get the rest of the screw out of the mounting hole. Not sure what kind of screws Sharp had qualified, whatever it was, it was way too soft.

Although the image was great, and playing back 4k @ 60Hz worked out well (much better than Sony and Samsung 4K TVs without jumping frames), the poor quality control and poor material used calls for a 1 star.

5.0 out of 5 stars Pixel perfect quality and vivid colors
Reviewed in the United States on April 8, 2014
I've owned these monitors for about a month now and it took a lot of tweaking to get them working at 60hz. Once I was able to run 60hz on both monitors flawlessly their true quality finally showed. Currently there's not much 4k support unless you're running the developer beta version of mac osx or windows 8. I had to wait until my mac pro arrived to finally utilize these monitors. Anything other than a mac running developer osx or windows 8 with very good and current graphics drivers won't deliver the full experience at the moment.
