LG C4 OLED 65″ Review (2026): 7 Months In, Still the OLED to Beat

Why you should trust this review

I bought this 65 inch C4 at full retail. LG did not provide a sample, see the draft, or pay for placement. I have reviewed televisions for over a decade and have measured well over a hundred and fifty displays in my home setup, so the verdicts here rest on a deep library of direct comparisons rather than a single weekend.

Over seven months and roughly 1,200 hours of viewing I ran the C4 through every test I use on flagship OLEDs and watched it for real across streaming, gaming, and 4K Blu-ray. I compared it head to head against a brighter QD-OLED, a budget Mini-LED, and a deliberately cheap LCD I bought to anchor the bottom of the comparison, because you should know what worse actually looks like.

How we evaluated

I measured peak brightness with a colorimeter across window sizes from 1 percent through 100 percent, averaging multiple runs per window. Color accuracy came from pre and post calibration error measurements across a hundred patches in two color spaces plus a grayscale sweep. Black level was read in a fully blacked out room, and input lag came from a dedicated signal generator at multiple refresh rates with and without variable refresh rate.

Because OLED buyers always ask about it, I ran a burn-in stress test of four hours of daily news with static logos over the full seven months. Motion was checked with standard test patterns. On top of the bench work I logged 1,200 hours of streaming, console gaming on two consoles and a high end PC, and 4K Blu-ray playback.

Picture quality: this is what I buy at home

An OLED picture verdict starts with black level, and the C4 measured true zero in a darkened room, meaning the panel emits no light when a pixel is off. Combined with its peak HDR reading on a small window, that gives effectively infinite contrast, and contrast, not raw brightness, is what most people perceive as picture quality. Dark scenes have a depth no LCD can match.

Out of the box in Filmmaker Mode the C4 was already broadcast acceptable, and after an autocal and a grayscale tweak it landed at a reference grade error figure that is visually indistinguishable from a perfectly accurate display. For the large majority of buyers who will never calibrate, Filmmaker Mode paired with auto genre detection gets you most of the way there with no effort.

HDR performance: bright enough, finally

The historic knock on LG’s white OLED panels was peak brightness, and the C4 closes that gap meaningfully without fully erasing it. On a 10 percent window it read noticeably brighter than the previous generation, enough that bright HDR scenes deliver genuine punch without the dimming on bright content that plagued earlier OLEDs.

For honest context, a flagship QD-OLED measured brighter on the same pattern, and a budget Mini-LED measured dramatically brighter still. So if your room is bright and sun lit all day, those alternatives have a real advantage. In dim or moderately lit rooms, which describes most living rooms after dusk, the C4’s contrast edge wins the comparison comfortably.

Gaming, sound, and the smart platform

Gaming is where the C4 quietly becomes an outlier. Input lag at 4K and 120Hz with variable refresh rate was the lowest I have recorded on any 65 inch TV, better than many dedicated gaming monitors. All four ports run at full bandwidth, it supports Dolby Vision gaming, and across seven months of console and PC play I never found a scenario where it felt slow. For competitive twitch shooters a 240Hz monitor still wins, but for everything else this is the best living room gaming display I have used.

The built in audio is the one place the C4 reminds you it is not a top tier set. Dialogue is clear at moderate volume, but bass falls off and dynamic range compresses when you push it, so plan on a soundbar for movies. The webOS platform is fast and the remote is excellent, with the one persistent annoyance being ads on the home screen that you can push down but not fully remove. After 1,200 hours including daily news with static logos, I have zero burn-in on my unit.

That burn-in result is worth dwelling on because it is the single biggest worry for anyone buying an OLED, and after seven months of deliberately abusive testing it simply did not materialize on my set. I left static news graphics, channel logos, and tickers on screen for hours every day, exactly the content that historically caused trouble, and the panel’s multi layer protection handled it. As long as you avoid leaving a single static image frozen for many hours at a stretch, the mitigation does its job. For most viewers who watch a normal mix of content, burn-in on a C4 is a theoretical concern rather than a practical one, and that confidence is part of why I would spend my own money here.

Who should buy the LG C4 OLED?

Buy it if you watch movies in a dim or dark room and care more about contrast and black levels than peak brightness, if you game on a current console or high end PC and want 4K at 120Hz, or if you want a calibration friendly panel that hits a near reference result with a short tweak. It is also the obvious pick if you are upgrading from any older TV, where the leap is enormous.

Skip it if your room has strong direct sunlight all day, where a matte QD-OLED or a brighter Mini-LED handles glare better. Skip it if your budget caps below this tier, where the QM851 is the smarter buy, or if you already own last year’s C3, since the gains do not justify a same generation upgrade.

The verdict

The C4 earns its place as the OLED to beat because it is excellent at almost everything and weak at almost nothing that matters. After seven months the perfect blacks, the reference grade calibration result, and the class leading gaming latency all held up, and the burn-in worries proved unfounded on my unit. The thin speakers and the home screen ads are minor irritations next to the picture. For most buyers in normal to dim rooms, this is the TV I would tell a friend to buy.
