Pretty disappointing: Looks terrible next to an iMac Retina 27" (even when running DisplayPort 1.2 at 60hz)

Summary: I had heard this monitor was a little flaky and lot expensive but that it offered excellent picture quality. I'm going to say that only two of three of these claims is correct: the picture quality is only mediocre (though I can confirm that the price is high and the monitor is a bit flaky). I connected this monitor to my iMac 27" retina using DisplayPort 1.2 (60hz) and immediately discovered two unpleasant things: a.
Excerpt: This is a high-DPI display, so you'll need capable hardware including a GPU with support for 60Hz 4K displays over Display Port, as well as software with good high-DPI support. Apple's Retina MacBook Pro and Mac Pro are perfect for this, as the density is similar to that of Apple's retina displays and Apple even lists this monitor as one of the explicitly supported 4K external displays.
Pros: Easy To Set Up, Easy To Use, Fantastic Image Quality, Great Color
Cons: Brightness Hard To Adjust, Gets Warm During Use
Terrible light bleed, cheaply made, unreliable, bad on both Windows and Mac, poor warranty terms

Summary: Windows 8 doesn't handle this resolution well. (Some items too tiny to read, others big and blocky--just a mess.) Mac OS (Mavericks and Yosemite) handles it gorgeously--but this monitor is not well compatible with the new Mac Pro: it fails to wake from sleep frequently, or fails to power on (says there's no signal), requiring me to force-restart the Mac and essentially crash my computer along with all open documents.
Love the pixel density but other issues prevent it from being a usable monitor.

Summary: Software is buggy, multi tile layout prevents me from using this monitor the way I intended. Sometimes computer won't resume from sleep if this monitor is plugged in. Came with dead pixels. Ordered an Asus monitor and have been much happier.
Summary: The picture is lovely - you can read the other reviews for details. However, this monitor presents problems for Mac users who wish to use it at 60Hz. You may find yourself stuck at 30Hz for one of two reasons. Thunderbolt 2 / DisplayPort 1.2 requirement: The display requires DisplayPort 1.2 for 60Hz use, otherwise it will run at 30Hz. If your Mac has Thunderbolt 2 ports, you then must enable DisplayPort 1.2 support in the monitor's menus to use it at 60Hz.
Don't waste your time buying and returning it later.

Summary: I don't know why Dell sells this "product". It's a prototype, not a product. I was looking for hi-dpi monitor, because I just can't look at anything else after Retina display of my laptop. Unfortunately I can say nothing good about it. 1. The backlight bleeding is terrible. You'll see it coming from all four corners of the monitor with any dark image displayed. Worst part - tech support confirmed that "it's within manufacturers guidelines". 2. Color temp.
Very nice and sharp. Some major caveats before using this with Windows, especially with Photoshop.

Summary: This monitor is a BIG step up from any older 23-24" monitor in terms of sharpness and contrast. You'll very quickly notice reduced eye strain, especially when reading text and working with precise controls in software. Unfortunately through no real fault of the monitor or manufacturer, this is still an "early adopter" purchase for sure, if you're reading this when Windows 8.1 is still current.
Summary: I bought this monitor about a week ago and it was great while it lasted. Unfortunately, I bought it used and perhaps as a result of that poor choice the left-hand side of the monitor's backlight went bad. At first it was a green cloudy discoloration - not unlike the discoloration one would find in cheap CRT monitors that required degaussing.
Summary: A very, very nice monitor. I'm using it with my late '13 Mac Pro and installation went very smoothly... 4K looks fantastic! I'd already downloaded and installed a couple of drivers from Dell's website, so all I needed to do was enable DisplayPort 1.2 on the monitor itself (so it would sync at 60 Hz) and it was a go! In my opinion this is a well made and great performing monitor.
