Which One Suits You?
LG C6 55" OLED AI 4K HDR Smart TV 2026 (OLED55C64LA)
Best overall
Who It Suits
Film fans and gamers who want a top-quality OLED picture, smooth 165Hz gaming and a slick smart system, without paying flagship money.
Who Should Not Buy
Anyone watching mostly in a very sunny room, or anyone who wants HDR10+ for Prime Video, which this TV does not support.
Pros
Superb OLED picture with natural, accurate colour
Excellent gaming features, with four HDMI 2.1 ports and up to 165Hz
Easy-to-use webOS with all the main catch-up and streaming apps
Cons
Glossy screen can reflect light in very bright rooms
No HDR10+, which only affects some Prime Video content
What Owners Say
Early verified buyer ratings at Currys are very positive, but the sample is still small because this is a 2026 model. Expert testers noted reflections from the glossy screen in bright rooms and some banding in smooth grey areas.
Sony Bravia 8 II 55" QD-OLED 4K HDR AI Smart TV (K55XR8M25BP)
Best for films and sound
Who It Suits
Film lovers who want accurate, cinematic picture quality and strong built-in sound without needing to add a soundbar straight away.
Who Should Not Buy
Gamers with several consoles, as only two ports support 4K at 120Hz, anyone with a very bright, sunny room, or anyone wanting the most picture for their money.
Pros
Superbly balanced, natural picture with deep blacks
Excellent built-in sound for a TV
Google TV with Dolby Vision and IMAX Enhanced support
Cons
Costs more than the other picks in this comparison
Only two ports support 4K at 120Hz, which matters if you own several consoles
What Owners Say
Verified buyer ratings at two major retailers are high across several hundred ratings. Expert testers say its main weakness is value, as its high price puts it behind some rivals on performance for the money.
TCL C7L 55" SQD-Mini LED 4K HDR Smart Google TV (55C7L-UK)
Best Value
Who It Suits
Families and gamers who want a bright, vivid picture for the money, especially in rooms that get a lot of daylight.
Who Should Not Buy
Film fans who watch mostly in the dark and want perfect blacks, or anyone who likes high volume without adding a soundbar.
Pros
Very bright, vivid picture that suits sunny rooms
Supports both Dolby Vision and HDR10+
Strong gaming performance with up to 144Hz
Cons
Built-in sound can strain at higher volumes
Standard-definition channels can look soft
What Owners Say
Verified buyer ratings at Currys are high across a good-sized sample. The main weakness, sound that strains at higher volumes, comes from expert testers rather than owners.

What To Look For
OLED or Mini LED: OLED screens light each pixel individually, so blacks are perfectly deep and pictures look superb in a dim room. Mini LED uses thousands of tiny backlights behind the screen, so it can go brighter, which helps in sunny rooms, but very dark scenes can show a faint glow around bright objects.
Check the model code: Some TVs are sold under slightly different names or codes at different shops, and the same range can come in more than one version. Always check the model code matches before you buy.
HDR formats: HDR makes highlights brighter and colours richer. Dolby Vision is used by Netflix and Disney+, while HDR10+ is used by Prime Video. A TV that supports both covers the most content.
Gaming: For a PS5 or Xbox Series X, look for HDMI 2.1, 120Hz and VRR (variable refresh rate, which stops jerky or torn pictures). All three picks have these, but the Sony has only two ports that support them, so check that is enough for your consoles.
Sound: Slim TVs have limited room for speakers, so a soundbar can be a worthwhile upgrade if you want fuller, more cinematic sound. The Sony is the exception here, as expert testers rate its built-in sound unusually highly.
Screen burn: OLED screens can retain faint marks if the same static logo is shown for many hours every day. Modern OLEDs have protection features, and it rarely affects normal mixed viewing.
Running costs: All TVs use noticeably more electricity in HDR and bright picture modes. Using the eco or standard picture mode for everyday viewing keeps costs down.
Safety: A 55-inch TV is heavy enough to cause serious injury if it tips. Use the anti-tip strap or a wall bracket rated for the TV's weight, especially if you have young children.

Frequently Asked Questions
Is OLED or Mini LED better for a bright room?
Mini LED is usually better for a very bright room because it can go brighter. OLED still looks good in normal daytime lighting, but reflections can show on glossy screens when sunlight hits them directly.
How far should I sit from a 55-inch TV?
Around 1.5 to 2.5 metres works well for most rooms. Closer distances suit films and gaming, while further back is more relaxed for everyday viewing.
Do I need a soundbar with a 55-inch TV?
Not for everyday viewing. A soundbar can be a worthwhile upgrade for films and sport, because slim TVs have little room for large speakers. Of our picks, the Sony sounds best on its own.
Is a 55-inch TV good for PS5 and Xbox?
Yes, as long as it has HDMI 2.1 and 120Hz. All three of our picks do, though the Sony has only two ports that support this. In the independent expert assessments we used, the LG C6 rated strongest of the three for gaming.
Will an OLED TV get screen burn?
It is unlikely with normal mixed viewing. The risk rises if you leave the same static image, such as a news ticker or game menu, on screen for hours every day.
