The 30-Second Version

The LG G5 is the brightest OLED we've tested, and it delivers stunning picture quality in any lighting. Movie performance is basically flawless, and gaming is excellent with 120Hz and VRR. If you can afford it, this is a top-tier TV, but budget shoppers might wince at the price.

Overview

The LG G5 is LG's 2025 flagship OLED, and it's all about brightness. With the new Alpha 11 AI processor and Brightness Booster Ultimate, this thing hits up to 1000 nits, a huge leap for an OLED. It's designed to look fantastic even in a sun-drenched living room, a rare feat for self-lit pixels. And you still get those perfect black levels and infinite contrast we all love.

The 55-inch model we tested lands in the top percentile for picture quality and connectivity. You get four HDMI 2.1 ports, every HDR format worth caring about, and a 5-year panel warranty that's genuinely reassuring. webOS is fine but just average, the only area where it doesn't excel. If you're after reference-level movie watching and responsive gaming, this thing absolutely delivers.

Performance

Performance-wise, the G5 is a knockout for movies, scoring 98.9 out of 100 in our database. The combination of perfect blacks and that 1000-nit peak brightness makes HDR content look jaw-dropping. Sports score a 94 thanks to excellent motion handling and wide viewing angles. Gaming is a treat with 120Hz, G-SYNC, and FreeSync support. The only low point is the built-in audio; the 4.2-channel setup is decent for casual use, but at this price, you'll want a soundbar to match the visual spectacle. It's no surprise this TV lands in the 92nd percentile for picture quality, the absolute best right now for movie fans.

Value & Pricing

The G5 doesn't come cheap. Prices vary by $781 across vendors, ranging from $1700 to $2481. You're paying a premium for that OLED quality and brightness upgrade. It's worth it if you want the best picture and a future-proof TV, but budget-conscious buyers can find incredible Mini-LED sets for less. If you're sold, shop around because that spread can save you real money.

vs Competition

Against the competition, the LG G5 holds its own with OLED's inherent advantages. The Sony BRAVIA 9 and Hisense U8 can punch brighter, so if your room is a glass box, those Mini-LEDs might edge out. But once the lights go down, the G5's perfect blacks and pixel-precise contrast make it the superior cinema display. The Samsung QN900F is 8K and eye-wateringly expensive, but at 55 inches, you won't see the extra detail from a normal couch. The TCL QM8K is the value king, but the G5 still wins on pure picture refinement. For mixed lighting and movie nights, this is the sweet spot.

Common Questions

Q: Does the LG G5 support Dolby Vision gaming at 4K 120Hz?

Yes, it handles Dolby Vision gaming at 4K 120Hz across all four HDMI 2.1 ports, so you're set for Xbox Series X or a high-end PC.

Q: How is the glare handling in bright rooms?

The new panel and anti-reflective coating are excellent, and it's one of the few OLEDs that stays watchable with sunlight hitting the screen.

Q: Is the OLED panel durable for long-term use?

LG backs it with a 5-year panel warranty that covers burn-in, and the OLED Care+ features automatically run pixel maintenance to extend the display's life.

Who Should Skip This

If you mainly watch cable news with static logos or leave the TV on all day as background noise, you might still stress about burn-in despite the warranty. If you're on a tight budget, the Hisense U8 delivers fantastic brightness and color for nearly half the price. And if you don't need all those HDMI 2.1 ports, a cheaper model like the Roku Pro Series will handle casual streaming just fine.

Verdict

If you're a cinephile or a serious gamer and you've been holding out for an OLED that can fight glare, the G5 is your TV. It's also great for anyone who hates the panel lottery of LCDs. But if you just want a big, bright screen for casual streaming, you can spend way less and still be happy.
