Rated 5 out of 5 by from An exceptional TV all round. This is an attractively designed TV for any home or office, with intuitive usage features for all. Set up is very simple and quick, almost plug and play, just adjust the language and it does seem to do the rest.

Rated 5 out of 5 by from Super smart for the money This tv offers a lot at great value price. It has so many functions available to you but is easy to set up and use. Links to you broadband system so you can see pics/video form your phone, pc etc. Super high quality screen image is displayed all the time. Used Netflixs to stream 4k videos and found the quality of picture superb. I have chosen to connect digital sound using the optical audio output to a sound box to listen to the tv but the tone and quality from the tvs own speakers is good. Visually the tv is very contemporary in design with minimal frame around the screen and will suit all types of room. Recommend to all.

Rated 5 out of 5 by from Excellent Great picture and features, very easy to set up and connect to WiFi. Would like to see a downloadable App to assist in setting up all the picture options.

Rated 5 out of 5 by from Great value 4K HDR TV This is a great TV. The picture quality on HD channels, Amazon Video & Netflix is amazing and sound is good for such a slimline TV. No All4 or My5 apps yet, but they are coming soon. The TV looks great too - far more impressive than competitor products of a similar price range. There is just one niggle - scheduled recording to USB doesn't seem to work following last week's software update, but I'm hoping the next update will fix this.

Rated 4 out of 5 by from Great TV let down smart hub faults. A great design TV with a very high quality picture, only let down by faults in its smart hub which Samsung support cannot put right after 2 resets. If you turn the TV off you have to reset the smart hub every time to put right the ITV hub and the same with youtube if you signed in using the app. It would get 5 stars if these faults where put right

Rated 4 out of 5 by from A very good TV picture and sound - assembly was a challenge and the Smart Hub seems to be lacking The 4K TV resolution is a significant step forward over the older HD standard. The KU6400 uses this feature to good effect and produces an outstanding picture quality. The KU6400 also comes with a good selection of signal input options and the built in FreeSAT also works well. One of my reasons for choosing this Samsung TV was due to the effective "Smart Hub" that was already being experienced on an earlier Samsung TV but the Smart Hub version on the KU6400 was disappointing when compared to the earlier version. Fixing the stand to the TV was also a challenge as some of the holes, for the screws supplied, had not been drilled. Overall the TV is a definite improvement over its replacement.
