      Rated 3 out of 5 by from Great TV if only all it's features actually worked. Would be 5 star all the way if Samsung would sort out the software bugs. The ITV Hub player does not work and I lose the local channels (BBC1, ITV, C4) every day meaning that I have to run a re-tune daily. I don't believe it's a signal problem as the channels are available on their source numbers e.g BBC1 on 959 is always present. I would recommend looking for a manufacturer where all the functions work.

      Rated 1 out of 5 by from Cheap at half the price. Great picture quality and was great value for a device with built in satelite tuner. When got home however, upgrading from an old SD freeview skybox to this device yielded poorer SD picture quality than the 10 year old skybox. Switching to HD was better but of course not all regular channels are available in HD. Recording live tv to memory stick does not work if the tv is left in standby so you have to leave the tv switched on all the time if you wish to record something. The recordings however are good quality. Even after several firmware updates, TV frequently loses its freeview channel list and needs to rescan, causing you to miss some of your program while it scans. Turned on today and now it no longer detects any satelite signal and its 2 and a bit years old. This is the second worst tv i have owned. The worst was an older samsung who's mainboard failed after about 100 hours viewing.

      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.

      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.
