Sometimes you have to unplug the power cord, and reattach it to the screen to start from display port
Affordable screen for those who are looking for high resolution. Works well in both OSX and Windows, however, have OSX horse lengths better scaling.
Colors and viewing angles are good, however, I feel that a modern 1440p screen is marginally better at the front.
The USB hub is unfortunately a step back from previous Dell monitors because it does not have any contacts p. Otherwise, the terminals are good and also the foot.
Owned screen approximately 1 year. Chose this screen after it and its smaller cousin received generally good reviews all over the place. Judging by the specs and reviews, this is in my opinion the best buy right now in terms of 4K IPS variants.
+ Sharp, good viewing angles, good color. No frills, but the basics supplies.
+ Just ok menu system with keys well spaced. No trouble.
+ 3x USB 3.0. Should all screens have today.
+ Height adjustable. Should also all screens have today.
- HDMI 1.4. Want to run 4k60hz (you would otherwise), it is thus DisplayPort apply.
- A bit rickety / plasticky. Directly mounted from the box on the desk tipped a few degrees, had to coax a little to get the panel horizontal. But now it has been guided by straight.
- The screen has a couple of times suddenly refused to find the signal on the MDP and DP ports. After some googling, it appears that the problem is common / name with the model and solved by unplugging the power cord and put it in again.
* I run this in 4K 60hz with Intel HD Graphics 5500, ie the second latest generation CPU. (The computer is a Dell XPS13 9343 (2015)). It's a bit sluggish at times when doing graphics-intensive grejjer in full screen (not games, usually Windows) Lesson learned: It is hard to push 4K at 60Hz even with Fairly new Intel chip.
The screen is what I expected, no more no less. I expected a good screen, and the screen delivers on all points that are important. Therefore, good grades.
Looking for a 4K IPS so check even on ViewSonic VP2780-4K.
Have two! One at work and one at home.
Why 4k? When you understand that the higher the resolution is not the same thing as "small icons" without having to run the scaling to really see the benefits: Smoother fonts, prettier pictures, etc.
Driving them for 6 months and have not experienced any problems.
Windows 10: Works well, when you learned that you have to restart your computer when you change the scaling (otherwise everything is completely blurred / blurred).
OSX: Works well.
Linux: Not tested.
