Samsung UE55MU6100 reviewSamsung UE55MU6100 review
The Samsung 55MU6100 gives you a big screen for little money - around 750 or less, which is extremely good value for a 55-inch TV. The MU6100 may be a budget TV, but it's a 4K model, HDR-compatible, with superb Smart TV. Watch out for the slow 50Hz refresh rate when watching sport, but otherwise consider this to be one of the great bargains of 2017.

LG OLED55B7V reviewLG OLED55B7V review
The LG OLED55B7V is an outstanding buy. OLED display technology gives you the best possible picture quality, and the B7 is the most affordable OLED TV in LG's 2017 range. It's super-stylish too too, with its blade-thin screen. It has superior audio and excellent Smart TV. The only issue is the price, but we expect this to fall.

Sony KD-55XE8596 reviewSony KD-55XE8596 review
The Sony KD-55XE8596 is a mid-range 55-inch TV with 4K HDR support. The slim aluminium frame and silver slate stand with neat cable management are attractive, and the TV comes with the benefit of Android Smart TV too. Picture quality isn't a match for Sony's more expensive models, and we feel the price ought to be lower to reflect that.

LG G6 reviewLG G6 review
The LG G6 is a premium metal-and-glass phone with a huge 5.7 inch HDR screen. Dual rear cameras, water resistance, Android 7 and a fingerprint sensor complete the package, but we're not sure why it's quite so expensive.

Sony KD-55XE9305 reviewSony KD-55XE9305 review
Sony's 55-inch XE9305B is a high-end LED TV that uses Sony's Slim Backlight Drive to generate impressive HDR images. Equipped with a 3-way audio system, it sounds as good as it looks. Factor in its slim good looks and Android Smart TV, and it's an all-round impressive TV. But the hefty price tag puts it out of range of most buyers, and there are smarter ways to spend your money.
