Samsung UE49MU6400


Samsung MU6400 series review: Sometimes you don't need to spend a fortune to get a good TV. This is one of the best TVs around £500.

Clean, sharp picture ; Good colours ; Nice design ; Good software ; Low input lag

HDR performance not hugely impactful ; Blacks are a little grey

For around £500, you’ll struggle to find better than Samsung’s UE49MU6400.

Good colour and sound


Our first move to larger screen. Picture quality noticably better. Sound improved by adding sound bar. For me all the features too complicated and easy to cause a problem which then takes some time to rectify

Great design and features


I upgraded from a Sony 4k TV and whilst the picture and sound quality isn't much better, the speed of the User Interface is... significantly. It may not matter to most people who have a Sky or other digital box connected, but the navigation is much...
