LG OLED evo AI G5 Review (2026): The Brightest OLED, Tested

The LG OLED evo AI G5 is LG’s 2025 flagship 4K OLED — the Gallery Series model built to hang flush on a wall like a painting. It sits above the popular C5 and represents the very best picture LG currently sells.

Two technologies define it. First, the new Alpha 11 AI Processor Gen2, which perceives objects with pixel-level precision to upscale and refine every frame. Second, Brightness Booster Ultimate — a breakthrough panel design that makes the G5 up to 45% brighter than its predecessor, attacking OLED’s one historic weakness.

Add 4K gaming at up to 165Hz, a Glare Free screen, webOS 25 and a 5-year panel warranty, and the G5 is LG’s statement piece. The question this LG G5 review answers is simple: is it worth the flagship price?

The G5 spans 55 to a colossal 97 inches, with the 65-inch model launching around $2,499 and the wall mount included in the box (a stand is sold separately, which is worth knowing before unboxing day).

As with every OLED, prices slide steadily after launch. Because the G5 is positioned as a flagship, the discounts tend to be larger in absolute dollars, so timing a purchase around seasonal sales can save serious money. We link to live listings below so you can check what your size costs today.

This is the headline of our LG G5 review. Measured on a 10% HDR window, the G5 reaches roughly 2,200–2,300 nits — TechRadar clocked 2,268 nits in Filmmaker Mode, and independent tests recorded up to 2,296 nits. For context, that is nearly double the LG C5 and ahead of Samsung’s rival flagship by a sizeable margin.

In practice, HDR highlights — sun glints, neon signs, explosions — carry a punch OLED simply never had before, while the self-lit pixels keep blacks perfect right next to them. Full-screen brightness lands around 360 nits, short of LG’s 400-nit promise but still a big step up, and SDR sits near a bright 465 nits. As a result, the G5 is the first OLED that genuinely thrives in a daylight living room, helped by a UL-verified Glare Free screen.

The Alpha 11 AI Processor Gen2 is LG’s most powerful chip, and it shows. AI Super Upscaling rebuilds detail in HD and streaming content with remarkable restraint — sharper without looking processed — while object recognition adds depth by separating subjects from backgrounds.

Color is reference-grade: independent measurements put DCI-P3 coverage near 99.8% with a Delta-E around 2, which means out-of-the-box accuracy most TVs need a calibrator to reach. Honestly, the one soft spot reviewers note is Dolby Vision handling, where some rivals squeeze slightly more out of the format. It is a nuance, not a flaw — but a flagship deserves honest nuance.

The G5 is arguably the most capable gaming TV on the market. All four HDMI 2.1 ports support 4K at up to 165Hz with NVIDIA G-Sync and AMD FreeSync Premium, and input lag measures an outstanding 9.2ms with Game Optimizer’s boost enabled (12.9ms without).

Combine that with OLED’s 0.1ms pixel response and the extra brightness headroom, and games look and feel spectacular — fast, fluid and vivid even in HDR. Features like Dark Room Mode and Multi View round out a genuinely first-rank gaming package.

The Gallery design is the G5’s second signature. With the supplied flush mount, it sits against the wall with virtually no gap — closer to framed art than electronics. The panel is barely over an inch deep with an ultra-thin bezel.

One practical note from this LG G5 review: there is no tabletop stand in the box. If you are not wall mounting, factor in the optional pedestal. LG backs the panel with a 5-year warranty, a quiet but meaningful vote of confidence in longevity.

webOS 25 is quick and intuitive, with AI-powered recommendations, voice control, Alexa built in and 350+ free LG Channels. Dolby Vision, Dolby Atmos and Filmmaker Mode are all aboard.

Built-in sound is solid for a panel this thin, and Wow Orchestra can combine the TV’s speakers with a compatible LG soundbar rather than replacing them. Still, a screen this good deserves a proper audio setup — budget for one if you can.

The honest comparison most buyers need. The C5 delivers the same perfect blacks, the same webOS and very similar gaming for hundreds less. What the G5 adds is decisive brightness (roughly double the peak), the newer Alpha 11 chip, 165Hz, the Glare Free screen and the flush wall design.

Therefore the choice is mostly about your room and your standards. Bright space, wall mount, the best picture money can buy — G5. Dim room and value focus — the C5 remains the smarter spend; our full LG C5 review covers it in depth.

Numbers aside, living with the G5 is the argument. HDR movies are the showcase: specular highlights — chrome, sun on water, muzzle flashes — carry an intensity OLED owners have never seen, while the pixel-level blacks keep night scenes immaculate. Filmmaker Mode with Dolby Vision content is as close to a mastering monitor as a living room gets.

Daytime is the bigger revelation. Sports and news stay vivid with the curtains open; the Glare Free coating diffuses lamps and windows that would wash out lesser panels. Meanwhile, upscaled HD content benefits from the Alpha 11’s restraint — clean and detailed, never artificial.

After weeks of mixed viewing, the consistent impression is headroom: whatever the content or the hour, the G5 has more to give than the material demands. That is what flagship money buys.

The classic OLED question deserves a straight answer, especially on a panel this bright. With normal, varied viewing — films, shows, sports, games — permanent image retention on a modern LG panel is very unlikely, and the G5’s 5-year panel warranty underlines LG’s own confidence.

The safeguards run automatically: pixel shifting, logo-luminance dimming and periodic panel-refresh cycles. The only genuine risk pattern remains hours of static, bright imagery daily for months — a stock ticker as wallpaper, say. For real households, it is a managed non-issue.

The essentials behind this review:

• Panel: 4K OLED evo with Brightness Booster Ultimate, Glare Free
• Processor: Alpha 11 AI Processor Gen2
• Peak HDR brightness: ~2,200–2,300 nits (10% window)
• HDR: Dolby Vision, HDR10, HLG
• Gaming: up to 165Hz, 4x HDMI 2.1, G-Sync, FreeSync Premium, ~9.2ms lag
• Audio: Dolby Atmos, Wow Orchestra
• Platform: webOS 25, Alexa built in
• Sizes: 55, 65, 77, 83, 97 inches; flush wall mount supplied, 5-year panel warranty

What we liked

• The brightest OLED yet — ~2,270 nits peak HDR
• Reference color accuracy out of the box
• Elite gaming: 165Hz, 4x HDMI 2.1, ~9.2ms input lag
• Flush One Wall design with mount supplied
• Glare Free screen works in bright rooms
• 5-year panel warranty

What could be better

• Flagship price
• No tabletop stand in the box
• Dolby Vision handling trails the best rivals slightly
• Full-screen brightness (~360 nits) misses LG’s 400-nit claim

The G5 is for buyers who want the best picture available without excuses: home-cinema enthusiasts, bright-room viewers who thought OLED was off the table, and serious gamers who will actually use 165Hz. It is also the obvious pick if you plan to wall-mount — the flush design is unmatched.

If you watch mostly in a dim room and care about value, the C5 gets you most of the experience for much less. But if the G5 is within budget, nothing in LG’s lineup — and little outside it — beats it.

The LG G5 fixes OLED’s last real weakness. With roughly 2,270 nits of peak brightness on top of perfect blacks, reference color and elite gaming, it is the most complete TV LG has ever made. The price is high and the missing stand is a quirk, yet as a flagship it delivers exactly what it promises.

For buyers who want the best AI smart TV picture of 2025, this is it.
