Great "Monitor" for Computer Use
|Posted .I went through a good number of screens before I found this one, including many purpose built computer monitors to no avail. I tried UHD and QHD, nothing I tried felt like a significant upgrade from my old LG 27" 1080p screens that I had three of in a triple screen setup. I was working with a good deal of real estate already, so I wanted something that could provide more. I tried out a few 27" 4K screens, everything was too small. I tried some 1440p screens, I wasn't impressed. I tried out an LG 4K IPS TV and I couldn't seem to find a happy place with the color settings. Then, I decide to try out this Samsung 40" 4K... and IT'S AMAZING! Of all the screens I tried (at least 6) this one has the best color reproduction and clarity with my Windows 10 system. I am running it from my ASUS Dual GTX1060 and it achieves 60Hz which is fine for me since I don't do a lot of gaming, mostly production. 40" is a really nice size for running 4K on your PC, a lot of real estate and the pixel density is great. The HDR mode on this TV give a very nice depth to your picture and the contrast is also very very good on this VA panel. I absolutely love the voice control remote, it's simple and now I don't like using the other remotes in my house because this one has spoiled me with it's ease of use and the button feel. Even the way this screen looks when it's off, that is to say the aesthetics, is great... it's a good looking TV both on and around the screen, looks very high end as compared to many other screens at comparable prices. I cannot recommend this screen enough for computer use, but of course it's excellent as a smart TV too. I just wanted to review it as a computer screen first and foremost because that will be my primary use of this 4K TV. There are some excellent reviews of the model on YouTube, in fact watching the review a friend of mine did on this TV is what made me decide to give it try, glad I did because I don't think I could go back to using anything under 40" @ 4K. Try it out, see what you think if you want a great screen for productivity... gamers might want something over 60Hz, but games still look amazing on this screen and are very playable @ 60Hz for me personally.

Great entry-level 4k HDR set
|Posted .Upgraded from a Samsung 32" 1080p (2015). I like the increased contrast and color quality. Seeing as most UHD blu-Ray players are at least as expensive as this set, I am holding out on 4k content. So far I have enjoyed screen sharing with my Samsung Galaxy Note 4. Hulu and Youtube look great! For anyone looking to start exploring 4k and all it has to offer, this TV is a great fit. I use my old Samsung remote from the aforementioned 2015 set. I did not like the smart remote.

Nice TV!!!
|Posted .My first smart tv. Easy to set up. Good picture. Bought a Samsung sound bar to go with it. Remote control sound button confusing until I figured out toggle. Optical cable - remove white protectors first. All the things I learned by trial and error with this tv are more common place now. Beats the heck out of my 15 year old 20 inch tv!

Great picture, great sound
|Posted .My previous unit (another brand) was affected by lightning and I needed to buy another. Prices are down considerably from a few years ago for the same size set. Each of my other 2 TVs are 4K smart units, and have excellent pictures. This new one is no exception, and the big plus point for me is the sound. Partly because I spent many years in the broadcast radio industry listening through very good studio speakers, and partly because I'm now an older American (hearing not as sharp as years ago) I find the listening very enjoyable; I did not have to go into settings and fiddle with the treble and bass settings. Straight from the factory it sounds just right !!! Almost forgot to mention the small, easy to use remote.

In love with my 4K TV.
|Posted .There are many TV sizes and since I have relocated many times over the years I wanted something that could be easily carried in such event. TV is well built, stands out and has many cool features. It auto updates and let you organize your favorite APPS in the main screen. To date I have no cable and am using the TV with online streaming hooked up straight to WiFi. So far great experience.

The TV functions better than anticipated
|Posted .I purchased this TV to double as a computer monitor. I live and work out of a travel trailer camper. Being limited on space the flatscreen TV meets my requirements. Being 4K I am able to turn the resolution up to limit any pixelation when connected to my computer. I am very happy with my purchase.

A great flat screen tv
|Posted .This Samsung TV has great color. It was the largest model that would fit perfectly in a wood entertainment cabinet we wanted to continue using. It was very easy to set up and hook to our U-verse system. Price seemed reasonable.

Q: Questionwhat is the difference between hdr pro and regular hdr?
Asked by henry.
- A:Answer I went to this link and both appears to be a split mirror image of each other for most features. The website (http://www.displayspecifications.com/en/) link below gives a side by side comparison: http://www.displayspecifications.com/en/comparison/d05f1b642 I was told by the BestBuy audio tech that HDR is simulated in theUN40KU6300FXZA model which is more that 2 years old now, and while the UN40MU6300FXZA model is full HDR. In addtion the UN40MU6300FXZA seems to have more premium audio sound capacity. Hope this help you in making a good purchase decision.

Q: QuestionI like this TV but have audio question. I raise volume level into the 70's range but still not loud enough. Is there a way I can resolve this issue? Or is there a manufacturer's defect?
Asked by Anonymous.
- A:Answer I had the same problem. In the Sound settings you have a choice of 3 or 4 options. I’m not looking at the tv right now, but they are something like loud, standard and mmaximize. We changed it from standard to maximize or something along those lines and that completely solved the problem.
