Excerpt: I have had this monitor for several weeks and find that it is just as good as the ASUS 32in 4K monitor except that it offers the opportunity to have Adobe RGB in addition to sRGB.Only reason for 4 stars is that I could not deal with the colors out of the box. However, once I calibrated it with the X-rite i1Display Pro, it matches the adjacent iMac 27 exactly.
Summary: 4K UHD is a brand new territory for high end monitors. For its first iteration intended for professional use, Dell has delivered a monitor that's both sharp and accurate. Pros: -- UHD Resolution really does make a difference. If you own Apple products, it's similar to the difference between a regular display and that of a Retina. Everything isn't just sharper but simply smoother and pleasing to look at.
Summary: I just got this a few days ago, and I got it to work on a 2014 MacPro right out of the box. The picture quality is exactly as advertised. I got it to work at 5-hz using the trick mentioned on the Apple user support , i.e. enabling DisplayPort 1.2. Sharpness is amazing. However, the USB ports do not work and DELL support is extremely unfriendly: standard answer, we don't support Apple.
Summary: This monitor brings a whole new sense to visualizing the work on a computer. The sheer size of the monitor can be almost overwhelming for the typical computing experience. It would work amazingly well for graphic design or for those jobs requiring in-depth clarity. The monitor turns on quickly The screen is antiglare. The image is in HD and to be honest watching a movie on this screen is almost worth the price alone.
Summary: The documentation that came with the product is fine, clear and well-written. The picture on this monitor is clear, bright and beautiful. I have not had any problems with it failing to wake up from sleep mode. I'm not a PC gamer so I can't comment on that aspect. I have used the monitor with photo editing software and I am very happy with the look and performance. If any issues arise, I will update this review.
Summary: Great monitor, and works flawlessly with Mac Pro late 2013. Currently running at 60hz using bundled cable. Make sure you change the setting on the monitor to support DP 1.2 which is not the default. Colors are vivid and very accurate. I am not using it for gaming but the response rate is slower than other cheaper 4K displays. It is pricey but well worth it.
