Summary: 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.
Excerpt: I have a new MacPro custom built 8 core. I use my new Sharp PNK 321 monitor for business, editing and all general purpose tasks.I do not believe there is a more clear quality monitor available in the market today. Love the quick wake up, perfection in color quality and ultimate sharpness. The monitor is bright and I do not like being away from the computer, it is that good!The monitor worked out of the box, but at week 5 it quite.
Pros: Best Available4k Awesome, Great picture quality, Large Viewing Area, Reliable Performance, Thoughtful Power Consumpt, Ultimate Sharpness, Very Responsive
Summary: 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.
Summary: 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.
Summary: 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.
Summary: 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.
Excerpt: I primarily use the PNK321 for photo & video editing of NEF files generated from multiple Nikon D800 36 megapixel bodies. With file sizes ranging from 15MB JPEG to 50MP NEF, I selected 2) PNK321 monitors to replace 2) 30" Apple Cinema monitors. The detail of the monitor is truly stunning - that is the strongest asset of this monitor. It is the most detail of any monitor i have seen. Engineering is a "C" compared with the Cinemas.
Pros: 2 Watts Channel Audio, 2 Wpc Audio Is Handy, Attractive Design, Bright, Easily Calibrated, Ideal For Apple Mac Pro, Striking Contrast, Stunning Detail, Thunderbolt Connection
Cons: All Plastic Design, Delicate, Generic Design, Hard Buttons On Side, Led Temp 96 Degrees F, No Match To Apple Design, Substandard Base Support, Windows Only Software
Excerpt: I bought this monitor to turn my new 15 inch MacBook Pro Retina into a desktop via HDMI. The 4K images are awesome. Resolution, color depth, angle viewing, all are perfect. Of course HDMI 1.4 is limited to 30 frames per second at 4K. But I don't detect unacceptable choppiness in the videos. It is easy to spot up-converted 4K videos from native 4K videos, as any freeze-frame quickly discloses. Converted frames are fuzzy, even though the videos look sharp in motion.
Summary: 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.
