Home cinema

It depends on how far you sit from the screen. Our 55 vs 65-inch guide puts a 55-inch TV at around 2.5 metres and says a 65-inch may feel more natural from 3 metres. Measure the wall too: the guide suggests a 55-inch where the space is under 140 cm wide.

It fits if it covers your TV's VESA pattern, weight and screen size. The One For All WM4661 takes VESA 100 x 100 to 600 x 400 up to 60 kg, and the Sanus VMF720 takes 32 to 55-inch TVs up to 25 kg. The 55-inch Samsung U8000H uses VESA 200 x 200; the 65-inch QN70H uses 400 x 300 and weighs 21.3 kg with its stand.

Not always. The Samsung B450F and the JBL Bar 1000MK2 come with a wireless subwoofer. The Samsung B400F has woofers built into the bar, and the JBL Bar 300MK2 is an all-in-one with no separate subwoofer to place, power or hide.

Usually by HDMI ARC or eARC, which carries the sound on one cable, or by optical. The Samsung B450F and the Majority Bowfell Halo use HDMI ARC or optical; the Sonos Ray uses optical and works with your TV remote through its IR receiver. The Samsung bars and the Bowfell Halo also take Bluetooth for music from a phone.

Yes. The Samsung U8000H, M70H and QN70H have a built-in DVB-T2 tuner for aerial channels such as Saorview, and the QN70H adds a satellite tuner. Samsung sets run apps on Tizen and LG sets on webOS, and the LG NANO NU85 lists RTÉ Player and Virgin Media Player.

It shows the TV's energy class on an A to G scale and its energy use in kWh per 1,000 hours, with a separate class for HDR pictures. A QR code opens the model's entry in the official EU database. The 55-inch Samsung U8000H, for example, is class F and uses 77 kWh per 1,000 hours for standard pictures.
