It's fine. The picture, the colors, the detail is great! The anti reflection is fantastic! However, there are competing brands with a lower msrp that look just as good and offer some nice features that this one dies not. Most importantly, a dual mode where one could increase the refresh rate while lowering the resolution. This is a common feature with high end gaming monitors that there is no excuse for one this expensive to not have.
I'd say if you want a great 4k picture and don't care about super high refresh rate and play in a bright room, wait for a sale and get it. This would be a good buy a $1,000. I recommend it to no one at $1900.00.
BTW Samsung needs to stop cheaping out on their pack in DP cables. 3' is not long enough!
