Input Lag?
I was reading a review and they mentioned that there was what appeared to be input when scrolling through text. One thing to keep in mind is that many times, the “artifacts” that people experience with 4K monitors are a result of the graphics system/card on their PC not being able to keep up, even if they are able to “address” the 4K resolution of the monitor. Keep in mind that a 4K monitor has 4X the number of pixels to deal with vs. a 1080p monitor. People that want high frame rates and 4K have to shell out for expensive graphics cards. If you just want one of these monitors as a replacement for (4) 1080p monitors as a work productivity monitor (and don't need the higher frame rates) a lesser capable graphics card/subsystem will suffice.
Outstanding monitor
The monitor I received is outstanding. I agree with the other reviewer in that if you don't have a video card that can drive this monitor properly you will not get its full potential. If you see ghosting or blur or any other performance issue, first check your video card and ensure it can drive the monitor properly. It's most likely your equipment, and not the monitor if you have issues.
Verified Purchase
Great, but ghosting and responsiveness issues
No discernible flicker, brightness uniformity is decent, the main problem is the responsiveness/input lag. When scrolling the previous frame's text (especially bolded, larger fonts) is visible for a fraction of a second. When watching videos the screen sometimes won't update quickly enough and you'll get a momentary jagged line across the video display. If you try to play games, you'll get this, thick, red-green shadow/outline following all moving objects/characters. I never intended to use this monitor for gaming, but the issues with text scrolling were unexpected. I'm considering returning it.
