LG C5 OLED Review: The OLED Everyone Should Buy First

The LG C5 OLED sits at number two on our Best TVs list with a 9.3, and after five straight generations of the C-series being the TV reviewers reach for first, this year's model gives the least reason yet to look anywhere else. Buy it if you want OLED's perfect blacks and best-in-class gaming performance without paying gallery-series prices. Skip it only if your room fights you with bright, uncontrollable ambient light — in which case the brighter LG G5 earns its premium.

What it actually is

The C5 is the mainstream expression of LG's OLED technology — the version built to be bought by the largest number of people, not the version built to set records. Its 4th-generation OLED evo panel delivers a real, measurable brightness increase over the outgoing C4, which matters because brightness has historically been OLED's one soft spot next to Mini-LED and QLED sets. That extra headroom means HDR highlights land with more punch and the C5 holds up better in rooms with some daytime light than any previous C-series TV.

The quieter upgrade is the Alpha 9 Gen8 processor's AI-driven upscaling. Most people don't watch native 4K content most of the time — they watch 1080p and sub-1080p streams that get upscaled on the fly, and that's exactly where the C5's processing shows up as a real difference rather than a spec-sheet number. Add four HDMI 2.1 ports, 144Hz refresh, 0.1ms response time, VRR, and ALLM, and the C5 covers both the cinephile and the console/PC gamer without asking either to compromise. It spans 42 to 83 inches, and at roughly $1,300-1,400 for the 55-inch — often discounted under $1,200 — it undercuts Samsung's S90D and Sony's A80L while matching or beating their picture quality in most rooms.

In use

Reviewers who've tested the C5 alongside its predecessors and rivals are unusually unanimous. Tom's Guide didn't hedge: "The LG C5 OLED is the best TV of 2026. So good, it forced me to reconsider what OLEDs can do — gorgeous, colorful picture quality and powerful 4K upscaling," and the outlet went on to name it their overall TV of the year. RTINGS, which has tracked the C-series since its debut, framed the C5 as the continuation of an established pattern rather than a one-off win: "The C5 continues the C-series legacy as the OLED most people should buy. LG's C Series OLEDs have become some of the most popular OLEDs on the market since 2016."

Wirecutter's framing is the most useful for a buyer trying to decide between this and something pricier: "For most people, the LG C5 Series provides a great-looking picture for a more reasonable price than the competition — terrific picture quality and tons of useful features." That's the whole thesis of the C5 in one sentence — it isn't chasing the best possible TV, it's chasing the best TV for the most people, and by most accounts it's still winning that race.

On the gaming side, Tom's Guide's measured numbers back up the marketing: "An impressively low lag time of 9.2ms in tests and up to 144Hz refresh rate makes it the best gaming TV we've tested." A new anti-glare coating also reduces reflections without introducing the graininess that made earlier matte attempts look worse in bright rooms than the reflections they were solving for.

Where it shines

• Best-in-class gaming feature set. Four HDMI 2.1 ports, 144Hz, 0.1ms response, VRR, and ALLM handle next-gen consoles and high-refresh PC gaming without asking you to pick between a "gaming TV" and a "movie TV."
• AI upscaling that actually matters day to day. Most viewing is streamed, sub-4K content — the Alpha 9 Gen8 processor's real-time upscaling is the upgrade that shows up every single evening, not just during a demo reel.
• The best price-to-performance ratio in the OLED class. Undercutting Samsung's S90D and Sony's A80L on price while matching or beating their picture quality is a rare combination, and it's the reason the C5 keeps landing on "best TV" lists rather than just "best OLED" lists.

The trade-offs — who should skip it

The C5 is the right call for the vast majority of living rooms, but the honest exceptions are specific:

• Your room has real, uncontrollable ambient light. The C5's brightness gains are real but not unlimited. If you're watching in a sun-drenched room with no blinds, the LG G5 OLED — LG's gallery-series flagship, 20-30% brighter — genuinely earns its higher price where the C5 would wash out.
• You want the flattest possible wall-mount install. The G5's flush-mount gallery design sits perfectly flat against a wall; the C5's design is good but not built for that specific aesthetic.
• You care more about color-processing philosophy than raw specs. Buyers chasing Sony's cinema-first picture processing over LG's brighter, gaming-forward approach should look elsewhere on the list.

How it compares

The C5 sits directly below the Sony Bravia 9 at rank one on Gavler's Best TVs list — a Mini-LED flagship that trades OLED's perfect blacks for Sony's professional-grade color calibration and higher peak brightness. That's a genuinely different technology bet, not just a step up in price. Within LG's own lineup, the LG G5 OLED at rank three is the closer comparison: same Alpha 9 Gen8 processor and identical 144Hz gaming suite, but a 20-30% brighter gallery panel and flush-mount design for roughly $1,100 more. For most buyers deciding between the two, the question is simply how much ambient light their room actually has — and for most rooms, the answer doesn't justify the G5's premium.

The Gavler verdict

A 9.3, driven by near-unanimous reviewer praise — RTINGS, Tom's Guide, and Wirecutter all independently landed on the C5 as the OLED most people should buy, and Tom's Guide went further, naming it TV of the year. The brightness gains close a real gap with pricier competitors, the AI upscaling is a genuine day-to-day upgrade, and the gaming feature set remains the class of the field. Buy it unless your room is unusually bright — in which case the LG G5 is the honest upgrade, not a marketing one.

Common Questions

Is the LG C5 OLED worth it in 2026?

Yes, for the overwhelming majority of buyers. It ranks second on Gavler's Best TVs list with a 9.3, and reviewers across the board — Tom's Guide, RTINGS, Wirecutter — call it the default OLED recommendation. The 4th-gen evo panel closes much of the brightness gap with pricier flagships, the AI upscaling meaningfully improves streaming content, and the gaming feature set is best-in-class. Only buyers with very bright rooms need to look elsewhere.

Should I buy the LG C5 or spend more on the LG G5?

Buy the C5 unless your room has significant ambient light you can't control with curtains or blinds. The G5's gallery-series panel is roughly 20-30% brighter and its flush-mount design looks better on a wall, but it costs nearly twice as much for a brightness advantage most living rooms don't need. For anyone watching TV in a normally-lit or dim room, the C5 delivers effectively the same picture for hundreds less.

Is the LG C5 good for gaming?

It's one of the best gaming TVs available at any price. Four HDMI 2.1 ports, 144Hz refresh, 0.1ms response time, VRR, and ALLM cover every current console and PC gaming need. Tom's Guide measured input lag at 9.2ms in testing — among the lowest of any OLED reviewed — so competitive players aren't giving anything up by choosing a TV that also does everything else well.

What size LG C5 should I buy?

The C5 spans 42 to 83 inches, and the 55-inch and 65-inch sizes are where most buyers land for typical living rooms, frequently discounted below list price. The panel technology and feature set are identical across sizes, so the decision comes down to room size and seating distance rather than picture-quality trade-offs.
