We purchased this 55" to replace the 52" Samsung that was in the living room (an early gift to the family). The colors are dynamic and very clear. Setup was quick and easy and we were up and rolling within 5 minutes. We love the Samsung TVs and will have them in the family for many, many years. As a side note, there was nothing wrong with the 52" (a little over two years old). We simply wanted to upgrade the main TV and now the 52" is in our bedroom!

This television has a great picture that is bright and good depth of color. The remote control and user interface on the television are super simple and it does everything needed. The user interface is very snappy and doesn't normally lag. My only complaint so far is that the TV doesn't come with the four screws needed to use the VESA mount. The VESA mount I purchased had the right screws except they were too long, I had to use a hacksaw to shorten the mounting screws. VESA mounting screws sould be included with the TV.

This TV has a great picture and several features. Got a great deal on it during the holidays. Replaced my old Plasma which was about 9-10 years old and the picture quality is such an upgrade. The smart hub is easiy to use and offers great features for streaming shows/movies and other content from any device.

This TV i just bought is amazing!! All of the setup was painless. My parents are getting older and they are not up to par with technology and this TV is very user friendly! My mom has no issues with going on the internet and also looking up any tv shows or movies. I would recommend this TV to anyone! GREAT JOB SAMSUNG!!!

We just bought this TV and love the picture quality, the ease of use of the remote, the user-friendly guide, and everything about this TV. I am so excited to have this although feel a little guilty that I put this in my bedroom versus the family room for everyone to enjoy!

I had purchased the 55" Class KU630D 4K UHD TV back in 2016. Since the day it was purchased, have had not one single problem with this TV. The color is still excellent, the sound is wonderful, anything can be plugged into this TV with no problem. Bluetooth settings are very easy to use and pairs with all my other devices. Love that one remote does everything. And on top of all that, it is so simple to go online with the browser that is already built in. Originally purchased this Samsung TV to replace a 55" Sony TV that one day without warning just shut off and would not come back on no matter what I tried. Sony's customer support was absolutely no help at all and told me I'd just have to buy a new TV. That TV was only 3 years old! And one month past the warranty date. So, didn't want to go that route again, & decided to purchase a 55" Samsung TV instead. Best purchase I have ever made. When this Samsung TV finally goes out, I will be purchasing another Samsung.

Picture is fine until light goes down and then TV gets dark and you have to change modes. Also, who builds a TV where when the indication light is lit, the TV if OFF? That's backwards! TV off, light off is what makes sense. Lastly, the TV doesn't shut off with the cable remote so you have to use both to turn the set on and off which is annoying. All in all a good tv for the price but a few design issues would have made it much better

This high resolution 4K device has exceeded my expectations for picture quality and audio performance. The remote device is adequate but needs a number pad aside from the on-screen one. The wall mount is excellent with tilt feature and secure fastening to stud and wall board for stability. Good choice for me at a good price.

This is the second 40" 4K Samsung I have purchased. I picked this one up for my daughter and she loves it. The image quality is amazing, it is easy to use, and the quality is what we have come to expect from Samsung. I will be picking up another one of these for my home office in the near future.

Pros: The picture quality seems to be nearly as good as tv's costing much more. The styling of the case is very classy looking. Nice thin black edges and no chrome or other distractions. The initial set up is quite easy, and it connects to HDMI, WIFI, or LAN inputs without any problems. The remote works well, and after some practice seems quite intuitive. Cons: There's a long series of steps to access picture and sound menus. The menus cover a large part of the screen so it's impossible to continue watching while adjustments are being made. Some settings are difficult to understand or over complicated. The controls on the tv are very difficult to use. Hope I never lose or damage the remote! There is only one component input. Switching from a VHS player to a DVD player, requires physical changes at the input cable connections.
