Best 55-inch OLED TVs in 2026

At 55 inches the C6 is the OLED most people should start with. It delivers what makes OLED special, with true black, no glow around subtitles and wide viewing angles, and it pairs that with the best gaming connections of any TV in this size.

LG's UK product page lists four HDMI inputs that all handle 4K at 120Hz, with variable refresh rate up to 165Hz, auto low latency mode and quick media switching. HDMI 2 doubles as the eARC port for a soundbar. NVIDIA G-Sync and AMD FreeSync are both supported, so a gaming PC works as well as a console.

LG reserves its brighter tandem panel for the 77 and 83-inch C6; the 55-inch uses the familiar OLED EX type. That means it should be a touch less punchy in HDR than the G6, but it is still a good fit for most living rooms, especially in the evening.

HDR support covers Dolby Vision, HDR10 and HLG, but not HDR10+. Sound is a 40W 2.2-channel system with Dolby Atmos, fine for everyday TV. In the US the same set is sold as the OLED55C6PUA.

The B6 is LG's entry-level OLED, and at 55 inches it is the most affordable way to get OLED picture quality from a major brand. It uses a standard WOLED panel and the less powerful Alpha 8 processor, but it keeps the perfect blacks and wide viewing angles that make OLED so good for films.

LG's UK page confirms four HDMI inputs that all support 4K 120Hz, VRR, ALLM and eARC (on HDMI 2), plus NVIDIA G-Sync and AMD FreeSync compatibility. That is unusually generous at this price and makes it a strong partner for a PS5 or Xbox Series X. The limit is 120Hz rather than the C6's 165Hz, which only matters for PC gaming.

The trade-off is brightness. LG puts the B6 below the C6, with the Alpha 8 processor and no Brightness Booster, so HDR highlights should have less sparkle and it will suit a dim room better than a sunny one. In the evening the gap matters much less.

The built-in 20W sound is basic, so budget for a soundbar if you can. In the US it is sold as the OLED55B6GUA.

The G6 is LG's premium OLED, and unlike the C6 it uses LG's brightest panel at 55 inches too. LG describes the G6 range as using its Primary RGB Tandem Panel 2.0, aimed at higher brightness and more vivid colour than the C6.

Connectivity matches the C6: LG's UK page lists four HDMI inputs with 4K 120Hz, VRR up to 165Hz, ALLM and QMS, with eARC on HDMI 2. The sound system is upgraded to 60W across 4.2 channels, and the panel is only 27.2mm deep, so it sits almost flat on the wall.

The UK model ending in LW is the wall-mount version. Versions without a stand come with LG's Zero Gap wall bracket instead, so check the listing if you want to stand it on furniture.

Is it worth the premium over a C6? If you watch in daylight, or simply want the best LG picture in a smaller room, yes. In a dim lounge the C6 gets you most of the way for much less. In the US it is sold as the OLED55G6WUA.

The S90H is Samsung's mainstream OLED for 2026 and the natural rival to the LG C6. Its big practical advantage is Samsung's Glare Free anti-reflection finish, which cuts down reflections from lamps and windows more than a typical glossy OLED screen.

Samsung's spec sheet, as reproduced by Euronics Ireland, gives every size from 42 to 83 inches a 100Hz native panel with VRR up to 165Hz, and all four HDMI inputs accept 4K at 165Hz with eARC. The 55-inch and larger sizes get Samsung's OLED HDR+ engine and FreeSync Premium Pro, as well as NVIDIA G-Sync compatibility. Sound is a 40W 2.1-channel system with Dolby Atmos.

There are two things to know. First, Samsung does not support Dolby Vision; you get HDR10+ instead, and Dolby Vision content falls back to standard HDR10. Second, Samsung uses different OLED panel types across the S90H range and does not say which one each size gets, so check the listing for the size you buy.

Samsung promises seven years of Tizen upgrades. In the US the 55-inch is sold as the QN55S90HAE.

Sony's Bravia 8 II launched in 2025 and remains Sony's flagship OLED in late 2026. It uses a QD-OLED panel combined with Sony's XR processing, and it is aimed squarely at people who care most about film and drama.

Sony tunes the picture for natural colour and skin tones, and the XR Processor is designed to handle lower-quality sources such as broadcast TV well. Sony's Acoustic Surface Audio+ vibrates the screen itself to produce sound, rated at 50W, which puts voices right where faces are.

Gaming is the weaker side. Sony's spec sheet confirms VRR only on HDMI 3 and 4, and one of those is the eARC port. If you use a soundbar, that leaves one fully featured input for a console. 4K 120Hz, ALLM and Dolby Vision are supported, but there is no HDR10+.

The 55-inch is 34mm deep and weighs 17.2kg without its stand, so it is thicker and heavier than the LG and Samsung sets here. The set came out in 2025, so check prices carefully; it is often discounted. In the US it is sold as the K-55XR80M2.

Panasonic's Z95B is the 55-inch OLED to choose if you do not want a soundbar. Panasonic's UK page confirms the Primary RGB Tandem panel, the HCX Pro AI MK II processor and the 360 Soundscape Pro sound system with Dolby Atmos, which includes upward-firing drivers and a forward-facing speaker bar built into the TV.

It is one of very few TVs that supports both Dolby Vision IQ and HDR10+ Adaptive, so whichever format a streaming service uses, the TV can make use of it, and both formats can adjust the picture to the light in your room. Panasonic tunes it for an accurate, cinematic picture.

For gaming, the European spec sheet labels HDMI 1 and 2 as 4K 144Hz inputs, with eARC on HDMI 2, so as with Sony you have one fully featured port spare if a soundbar is connected. VRR, ALLM, FreeSync Premium and G-Sync are supported.

The speaker bar makes it taller than other 55-inch OLEDs (764mm without the stand) and heavier, at 19kg. The Fire TV interface includes Freely in the UK. It launched in 2025 and remains Panasonic's flagship OLED.

Philips' OLED811 is the most complete mid-range OLED on paper. TP Vision says the 55-inch uses an OLED EX panel with a claimed 2,500-nit peak, runs at up to 165Hz and has four HDMI 2.1 inputs, so it matches the LG C6 for gaming. It also supports every major HDR format, including Dolby Vision 2 Max and HDR10+, something neither LG nor Samsung can say.

The headline feature is Ambilight: LEDs on three sides of the TV project colours from the picture onto your wall. It makes the screen feel bigger and reduces eye strain in a dark room. AmbiScape can also sync up to four smart lights.

The 70W 2.2-channel speaker system is more powerful than most rivals at this size. The weak point is the software. TitanOS covers the main streaming apps, but its app store is smaller than Google TV's, so check your must-have services before buying, or plan to add a streaming stick.

The 55-inch was the first OLED811 size to launch, in June 2026. Coolblue lists it at 14.9kg without the stand and 39mm deep.
