The LG C6 is the TV we’d point most people to if they watch in the evening, play games and want one screen that does everything well. It keeps what made the C-series the default OLED pick, perfect blacks, wide viewing angles and four full HDMI 2.1 ports, and adds a faster processor, a brighter panel and a 165Hz ceiling for PC gamers. It isn’t flawless: it’s a modest step over last year’s C5, skips HDR10+ and DTS, and its speakers don’t match the picture.
LG C6 OLED (42 to 65 inch)
8.9/10 CouchSetup score
Best for Movie nights, gaming and mixed-light living rooms
- Self-lit OLED: perfect blacks, no blooming
- Four HDMI 2.1 ports, up to 4K 165Hz
- Dolby Vision, including Dolby Vision gaming
- Sizes from 42 to 65 inches, plus 77 and 83-inch C6H
Prices change often, so check today’s price on Amazon.
Our verdict
Short verdict (8.9/10): a brighter, faster, very accurate C-series OLED with class-leading gaming features. Buy it for dark and mixed-light rooms. If your TV faces a sunny window, look at a Mini LED like the TCL QM7L, and if price matters most, a discounted C5.

What the reviews don’t tell you
The size you buy changes the TV
TechRadar reports the 42 to 65-inch C6 uses the same kind of panel as the C5, while the 77 and 83-inch C6H gets the G6’s brighter Primary RGB Tandem panel. It also notes the 42 and 48-inch models are a bit less bright than the bigger C6 sizes because their pixels are packed more tightly. The lab results below are all from 65-inch samples, so they don’t describe every C6.
C6 vs C5 in numbers
| TechRadar result (65-inch) | LG C5 (2025) | LG C6 (2026) | Change |
|---|---|---|---|
| HDR peak, 10% (Filmmaker) | 1,180 nits | 1,438 nits | about +22% |
| HDR peak, 10% (Standard) | 1,191 nits | 1,291 nits | about +8% |
| Full-screen HDR (Filmmaker) | 195 nits | 245 nits | about +26% |
| Max refresh | 144Hz | 165Hz | PC only |
A 22% brighter highlight is visible but not dramatic, and 165Hz only matters for a PC, since consoles top out at 120Hz. That’s why both TechRadar and Tom’s Guide say a heavily discounted C5 is better value for many people.
Three full-speed ports stay free with a soundbar
The soundbar takes the eARC port, which on the C6 is still a full HDMI 2.1 port. That leaves three full-speed inputs for a PS5, an Xbox and a PC at once, more than Mini LED rivals like the TCL QM7L, which has two 144Hz ports.
Picture quality
Brightness is the big upgrade. TechRadar measured about 1,438 nits on a 10% HDR window in Filmmaker Mode and 1,291 in Standard; Tom’s Guide got 1,355. Highlights like sunlight on water have real sparkle. Full-screen brightness is still limited at about 245 nits, so snowy scenes and bright sports look less dazzling than on a Mini LED, which is why we steer very bright rooms elsewhere.
Blacks are perfect and there’s no blooming around subtitles, and viewing angles are excellent. Color is very accurate out of the box: TechRadar measured a Delta-E of about 1.2 and 99.7% DCI-P3, Tom’s Guide 1.53 and 99.77%. Reflections split the reviewers: Tom’s Guide called the screen virtually reflection-free, TechRadar listed reflections as a con in a bright room. Lamps and windows directly opposite will show; side light is handled well. TechRadar also spotted occasional banding in smooth gradients, a minor OLED quirk.
Gaming
One of the best gaming TVs you can buy. TechRadar measured about 9.2 ms of lag at 4K 60Hz and 4.6 ms at 1080p 120Hz; Tom’s Guide got 9.1 ms in Boost mode. OLED’s near-instant response keeps fast motion crisp, and the Game Optimizer puts it all in one menu. See best TVs for PS5 and Xbox and couch gaming setup.
Sound and software
The 2.2-channel speakers are fine for news, but TechRadar and Tom’s Guide both found them thin next to the picture, and there’s no DTS. Budget for a soundbar like the Sonos Beam (Gen 2); HDMI ARC vs eARC explains the hookup. webOS 26 is quick with every major US app and AirPlay. The home screen shows promoted content, which What Hi-Fi confirms you can turn off. The redesigned Magic Remote has no mute button, so assign mute to the heart button on day one.
Settings to start with
| Setting | Starting point | Source |
|---|---|---|
| Picture mode (movies) | Filmmaker Mode | TechRadar, Tom’s Guide |
| Near Black Detail | -1 | TechRadar, What Hi-Fi |
| Adjust Contrast / Black Level | 95 / 49 | TechRadar |
| TruMotion | Cinematic Movement | What Hi-Fi |
| AI HDR Remastering | Off | Tom’s Guide |
| Gaming | Game Optimizer, Boost, VRR on, HGIG | TechRadar, Tom’s Guide |
There’s no brightness penalty for the accurate mode: Filmmaker measured brighter than Standard in TechRadar’s test. More in our picture settings guide. Tom’s Guide lists the 65-inch at 56.7 × 32.5 × 1.8 inches and 36.6 pounds without the stand; the 55 and 65 use a center stand, so check depth as well as width.
Which size
| Size | Immersive (40°) | Comfortable (30°) | Typical room |
|---|---|---|---|
| 42 in | 4.2 ft | 5.7 ft | Desk or small bedroom |
| 48 in | 4.8 ft | 6.5 ft | Bedroom or compact living room |
| 55 in | 5.5 ft | 7.5 ft | Most bedrooms, small living rooms |
| 65 in | 6.5 ft | 8.8 ft | Most living rooms |
Sitting farther back? The 77-inch C6H gets expensive fast; a 75 or 85-inch Mini LED like the TCL QM7L is the budget way to go bigger. See 65 vs 75 inches.

The step-up G6 adds an anti-reflection screen, the better OLED for a window-facing wall. For matte-screen options, see best TVs for bright rooms; for the panel-type question, OLED vs Mini LED.
How we picked
We gathered the measurements and expert reviews (TechRadar, Tom’s Guide and What Hi-Fi), put them side by side, and worked out what the individual reviews leave out, like how the size you pick changes the panel. Specs were checked against LG’s listings and TFTCentral. Where outlets measured different numbers, we say so. Every source is listed at the end.
FAQ
Is the LG C6 worth it over the C5?
Only if the price gap is small or you want 165Hz PC gaming. A heavily discounted C5 is better value for many buyers.
Does the LG C6 support HDR10+?
No. It supports Dolby Vision, HDR10 and HLG.
Is it good for PS5 and Xbox?
Yes. All four ports do 4K 120Hz with VRR, and lag measured around 9 ms at 60Hz and under 5 ms at 120Hz.
Is it good in a bright room?
It’s fine in moderate light, but a bright Mini LED or the anti-reflection G6 is better for a sunny room.
Are all C6 sizes the same?
No. The 77 and 83-inch C6H uses a brighter panel, and the 42 and 48-inch are a bit dimmer than the 55 and 65.
