LG OLED55C6 55 inch OLED TV at a glance
Top tip: putting the TV on a cabinet? The 55" sits on a single central stand measuring 470 mm wide × 230 mm deep, so it fits plenty of existing units — just check yours is at least 230 mm deep. The screen itself is 1,222 mm wide. Prefer it on the wall? See the Vogel’s mounts above.

The Jennings Verdict — LG OLED55C6
LG’s best C-series yet
The Alpha 11 AI Gen3 processor from the flagship G6 brings brighter, more precise pictures than any C-series before it.
Great from every seat
Self-lit pixels with UL-certified Perfect Black and Perfect Colour — the picture holds up from any angle in the room.
A gamer’s favourite
Four HDMI 2.1 ports, 4K@120Hz for PS5 and Xbox, up to 165Hz for PC, with G-Sync and FreeSync Premium.
Easy to place
A compact central stand (470 × 230 mm) means it fits most TV units, and on the wall it’s just 45.1 mm deep.
Add a soundbar for films
Like most slim TVs, the built-in speakers are basic — a Sonos soundbar connects over eARC for Dolby Atmos.
5-year warranty included
Year 1 with LG and years 2–5 with Domestic & General — and we register it for you. On demo in Fleet.
Flagship processing, for the first time
For the first time, the C-series gets LG’s most powerful processor — the same Alpha 11 AI Gen3 chip as the flagship G6. It analyses everything you watch in real time for brighter highlights, more precise colour and smoother gradation than the outgoing C5.
Perfect Black, Perfect Colour
Over 8.3 million self-lit pixels each control their own light, so blacks are absolute and contrast is effectively infinite. LG’s Perfect Black and Perfect Colour are independently certified by UL, and the picture keeps its depth and accuracy from any angle.
webOS 2026 smart TV
Netflix, Prime Video, Disney+, Apple TV+, BBC iPlayer, ITVX and more are built in, controlled by the AI Magic Remote with voice control. webOS Re:New provides software upgrades for up to five years — and LG’s smart platform has won AVForums’ Editor’s Choice for eight years running.
Built for gaming
Four HDMI 2.1 ports with 4K@120Hz for PS5 and Xbox Series X, VRR up to 165Hz for PC, NVIDIA G-Sync and AMD FreeSync Premium, a 0.1ms response time and Dolby Vision gaming.
Slim OLED evo design
At just 45.1 mm deep, the OLED55C6 sits neatly on its stand or almost flush on the wall. Our own installers can wall-mount it, hide the cables and set everything up for your room.
Enhance your TV sound with a soundbar
Like most slim TVs, the C6’s built-in sound is basic. A Sonos soundbar gives you clearer vocals with Speech Enhancement, richer bass and Dolby Atmos for films. The Beam Gen 2, Beam Ultra and Arc Ultra each connect to the TV’s eARC HDMI port with one cable and work with your TV remote. You can add a Sonos Sub Mini or Sub 4 later for deeper bass.

Questions about the OLED55C6
Is 55 inches the right size for my room?
55" suits viewing from roughly 2 to 3 metres — the distance in most UK living rooms. If you sit further back, the 65" C6 may suit you better; come and compare sizes in our Fleet showroom. Read our TV size guide.
Is the LG C6 good for gaming?
Yes — it’s one of the best gaming TVs you can buy. All four HDMI 2.1 ports support 4K@120Hz from PS5 and Xbox Series X, with VRR up to 165Hz from a PC, NVIDIA G-Sync, AMD FreeSync Premium, a 0.1ms response time and Dolby Vision gaming.
What’s the difference between the LG C6 and G6?
The G6 is LG’s flagship OLED, with a brighter panel and a gallery design made to sit flush on the wall. The C6 now shares the G6’s Alpha 11 AI Gen3 processor, so it gets much closer than previous C-series TVs, for less. Come and compare them in our Fleet showroom.
How big is the stand — will it fit my TV unit?
The OLED55C6 sits on a single central stand measuring 470 mm wide and 230 mm deep, so your unit needs a flat top at least that size. The TV itself is 1,222 mm wide. If your unit is too small, wall-mounting (VESA 300 × 200) is the easy answer.
Can the OLED55C6 be wall-mounted?
Yes. It uses a VESA 300 × 200mm fixing and weighs 14.1kg without the stand, so it suits the Vogel’s mounts above. Our own team can wall-mount it, hide the cables and set it up for you.
What warranty does it come with?
The OLED55C6 comes with a 5-year warranty: LG covers year 1, and Domestic & General cover years 2–5 — we register it for you. 5-year warranty details.
Do you deliver, and can I see it first?
We offer free local delivery around Fleet and nearby towns including Farnborough, Camberley, Farnham, Aldershot and Yateley. The C6 series is on demo in our Fleet showroom at 185 Fleet Road, GU51 3BL — walk in, or book a time.
