The LG OLED evo C4 is the OLED most people should buy. A brighter evo panel, the lowest input lag we measured at 5.8 ms and four full HDMI 2.1 ports make it the rare TV that does film, sport and gaming equally well. Here is exactly what it does, and where it stops short.
LG has built more OLED TVs than anyone, and the C-series is the model that defines the mainstream OLED every year. The C4 (the 55-inch is the OLED55C4) is the 2024 evolution, and it is the best version yet for the money. It does not chase a single headline spec; instead it gets the whole balance right, which is precisely why it tops our ranking. Across two weeks on the bench it never gave us a reason to dock it, and at £1,199 for the 55-inch it is the easiest OLED to recommend without caveats.

The verdict from Idris Bello, home cinema and TV tester
Our best overall pick. The LG C4 is the OLED most people should buy: a brighter evo panel that hit 1,065 nits on a 10% window in our tests, four 48 Gbps HDMI 2.1 ports, and class-leading 5.8 ms input lag at 120 Hz. It does film, sport and gaming equally well, and at £1,199 for the 55-inch it is the easiest OLED to recommend without caveats.
Perfect blacks, punchy highlights and motion so clean that 24 fps film and 120 fps gaming both look right.

The C4 is the right TV if you want one set that does everything well. It is the all-rounder: bright enough for a normally lit living room at 1,065 nits, fast enough for any console at 5.8 ms of input lag, accurate enough for film, and equipped with four 48 Gbps HDMI 2.1 ports so you can connect a PS5, an Xbox Series X, a PC and a soundbar at once without juggling cables. It comes in 42, 48, 55, 65, 77 and 83-inch sizes, so it scales from a desk to a home cinema wall. For roughly 90 percent of buyers, this is the OLED to get.
It is less essential if you have a specific, narrow priority. If you only watch films in a blacked-out room and never game, the Sony BRAVIA 8 edges it on pure accuracy. If you want the brightest possible HDR, the Panasonic Z95A hits 1,460 nits against the C4 1,065. And if your budget is tighter, the LG B4 gives you the same OLED blacks for £450 less. But none of those is a flaw in the C4; they are simply cases where a specialist beats a generalist.
On the bench the C4 reached 1,065 nits on a 10% window in Filmmaker Mode, around 20 percent brighter than the older C3 and a meaningful step up for HDR. Full-screen white sat near 230 nits, typical for OLED, so it is the highlights that benefit most. Colour coverage measured 98.5 percent of DCI-P3, and out-of-the-box accuracy in Filmmaker Mode was excellent, with a greyscale Delta E comfortably under 3, the point below which errors are invisible to the eye. Black level is, as with every OLED here, a true zero, giving effectively infinite contrast. In a dark room the picture is genuinely cinematic; in a normal living room with the lights on, the evo panel has enough punch to keep HDR looking like HDR.
OLED near-instant pixel response means motion is naturally clean, and the C4 a9 Gen 7 processor handles 24 fps film cadence without judder and upscales 1080p sources cleanly. The panel runs at a native 120 Hz and accepts up to 144 Hz from a PC. Across fast sport and panning shots there was no smearing, and the optional motion smoothing can be dialled down or off to keep films looking like films.
This is where the C4 pulls clear. We measured 5.8 ms of input lag at 1080p/120Hz, the lowest of all six TVs on test. It carries four full 48 Gbps HDMI 2.1 ports (every input, not just two), supports 4K at up to 144 Hz, and runs VRR including Nvidia G-Sync and AMD FreeSync Premium plus ALLM. The webOS Game Optimiser overlay lets you change settings without leaving the game. For a household with a PS5, an Xbox Series X and a gaming PC, the C4 is the most capable OLED you can buy at this price.
The C4 runs webOS 24, which is fast and well organised, if busier with recommendations than it used to be. The built-in 2.2-channel, 40 W speaker system is fine for everyday TV but, as with most OLEDs, a soundbar is a worthwhile upgrade for films. It supports Dolby Vision and Dolby Atmos, plus eARC to pass lossless audio to a soundbar.
There is little to criticise, but two things are worth flagging. The pedestal stand can wobble slightly if you knock the set, and the C4 has no built-in satellite tuner (it uses the standard terrestrial tuner plus apps). Neither affects the picture, and both are minor next to what the C4 gets right. It is also not the brightest OLED here, so for a very bright, sunlit room the Panasonic Z95A or a Mini-LED would cope better.
The C4 is best for the buyer who wants one TV to do everything: film, sport, streaming and serious multi-console gaming, in a normal living room, at a sensible price. If that is you, stop here. If you have a narrower priority, see the BRAVIA 8 for film, the Z95A for brightness, or the B4 for budget.
It is the best gaming OLED in this comparison. It has four full 48 Gbps HDMI 2.1 ports, a 144 Hz refresh rate, VRR including G-Sync and FreeSync Premium, and we measured 5.8 ms of input lag at 1080p/120Hz, the lowest figure of the six TVs we tested. The webOS Game Optimiser overlay also lets you tweak settings quickly without leaving the game.
We measured 1,065 nits on a 10% window in Filmmaker Mode, a clear step up from the older C3 and bright enough for a normally lit living room. It is not as bright as a Mini-LED or the flagship Panasonic Z95A at 1,460 nits, but for a dark or dimmable room it has plenty of HDR punch.
The C4 comes in 42, 48, 55, 65, 77 and 83-inch sizes. The 55-inch we tested suits a viewing distance of around 1.8 to 2.2 m and is the sweet spot for most UK living rooms. The 42 and 48-inch models are excellent as a large gaming monitor or for a small room or desk.
The C4 is our best overall pick because it wins on balance rather than on any single number. It pairs a bright 1,065 nit evo panel with the lowest input lag on test at 5.8 ms, four 48 Gbps HDMI 2.1 ports, Dolby Vision support and class-leading 98.5 percent DCI-P3 colour, and it has no weakness that matters for most homes. At £1,199 for the 55-inch it represents the strongest blend of picture, gaming and value of any OLED we tested. If you want a single set that does everything well, this is it.
