I have to give this a 1/5 because I received it with a dead pixel cluster

Either they're dead pixels or there's something stuck in the material inside

Dead pixels galore

This panel is actually pretty awesome; there were no dead pixels, and 4k was beautiful

Screen had scrapes, screen had a cluster of 10+ dead pixels in the middle, screen had what looked like a hair inside the screen

However, the one I received this time was malfunctioning, it had dead pixels and the right side of the screen has a ‘red overlay’

No dead pixels, out of the box colors are great, menu screens are a bit awkward with the joystick on the rear, but manageable

I exchanged it, and the second one had a couple/few dead pixels again, in the same far upper right corner.

No dead pixels

I will update this comment later.(What amazed me most is they both have dead pixels, great job Samsung!

Now a days I do understand that due to the insane number of pixels and the microscopic size that a few (3-6) pixels will be dead and the display still passes QA tests.

Bought the first one and it had a blotchy spot that could be seen off-center, and it also had a couple dead pixels in the far upper right corner.

I've searched and been unable to find any dead pixels

Good looking monitor, but lots of dead pixels

No dead pixels

No dead pixels on arrival

Quality Issue: No dead pixels, but one of the two monitors I received cannot display UHD at 60hz as advertised.

Being as this is the first 4k monitor I have ever purchase, I was sure to check for bad or dead pixels once I received them

Constant strobing and flickering, dead pixels, and overall very poor image quality which no amount of tweaking would fix

So I think I'm just going to return it, don't want to get a third one with dead pixels.

This monitor arrived a week ago and I just noticed a bunch of dead pixels on left corner

Already have dead pixels

n’t have any issues with it and no dead pixels it does put out 4K at 60hz with my Xbox

and there's a horizontal dead pixel line

Quite distracting when there is a large clump of dead pixels directly in the middle of the screen

No dead pixels, out of the box colors are great, menu screens are a bit awkward with the joystick on the rear, but manageable

Arrived with a single dead pixel, Because of this they are given 2 stars

Trust me, if you have even one dead pixel, it's a pain, because you're going to look at that one dead pixel all the time.

The monitor looks fantastic and had no dead pixels out of the box

Dead pixels galore

Had a dead pixel area, not only a pixel

No noticeable dead pixels....surprisingly.

Monitor has developed a nice cluster of dead pixels after three months of light gaming use

Had to do some driver updates on my pc and did some color tests and calibration tests online (google 4k monitor tests) - checking for dead pixels and all sorts of stuff

Out of all these Samsung screens, there is NOT ONE DEAD OR STUCK PIXEL!!!

No dead pixels, great price(during the holidays).

I'm rating them 4 instead of 5 stars as both have a cluster of a few dead pixels

For the sale price I am very happy, but did have a dead pixel and light bleed

Has an even larger dead pixel cluster that is impossible to ignore

Each one had dead pixels or dirty screen defects

Not a single dead pixel and works great in the office

Great QC on the last one I received though, no bad/dead pixels there!2

no missing pixel no turning off then back on

Of course the pixels are as crisp as it can be

It appears a horizontal line of dead pixels after 5 days of use

mediocre not worth the money, came with a few dead pixels and colors are not vibrant at all

I did not return the monitor due to a dead pixel, On a 4K monitor it is hardly noticable but is still unacceptable

Manufacturer not catching one monitor with one bad pixel and one dead pixel, and then another one with one bad pixel and a 2-3 pixel cluster that was dead.

I was deeply saddened by the late arrival as well as the dead pixels and fuzzy appearance at QHD res.

The picture looks amazing like expected, and it's great with backwards compatibility for 1080 P
