Awesome product! Very very very great value for the money! =)

Though it was a "used for 6 months" item, it comes like new, without dead pixels, or something wrong. Price was a great reason to buy and a great opportunity for me even in a Country with abusive taxes (Brazil). I like the image quality. It's amazing. Obviously because it is a 4k monitor. Before it, I had a Full HD "IPS monitor". So I can say: even being a "TN monitor", the colors are incredible. The presets are satisfactory. But if you have some experience, or curiosity, you could calibrate it like I did. The auto upscaling function seems very convenient. Because you do not have many contents in 4K resolution on web. But for gamers it is amazing, because there are not many rigs that can run 4k games with ease. I did some tests with Assassin's Creed Revelations with 4K native and with 4K upscaling (playing at 1k and the monitor doing the rest). Some friends I show it said that in native 4K AC Revelations seems, visually, like AC4 Blackflag. I did these tests with AA and without AA in both options (native and upscaling). Tests with the upscaling function reduce satisfactorily some needs of a high AA. But tests with the 4K native reduce much more, hehe. I did some tests with my cousin's Xbox One consoles and friends (I will do with my friend's PS4 too). They played many hours with my 4k monitor and they said some games had better visual gain than others, but every game had a gain on Xbox One (played in Full HD upscaled by the 4K monitor. Xbox One do not show 4K option on its configuration). I dislike, like almost 100% of the people who bought this monitor, the base panel. It seems fragile. But if you take care, I know you will, it is not a problem for the price you pay for this monitor. Even a price of a new one is cheap (except in Brazil), considering that you will have a incredible image. So you could not require something better than this. I have navigating on the web and saw that the biggest difference between Samsung's 4K from ASUS's 4K monitor is the stand. On ASUS you pay a bit more for a "better suitable stand" and VESA mount. The ASUS's stand turn 180°, and have a better "tilt" angle. The quality of the image is the same. The functionality I cannot say because I do not have this one. I recommend this item for those who do not use or need VESA mount, great tilt and stand that turn 180°. And for those that want save a few bucks. Another thing to say is that the characters are very little because the resolution. For me it's not a problem. If it is a problem for you, change the size of the letters on your OS and everything will be all right. That's all! I think... Oh! I forgot to say that i would to buy another 4K monitor, for sure, if I had a computer capable to handle two monitors, but i don't have, so... I can only recommend to you. It really value the money.Read full review
