LG OLED The TVs have consistently ranked among the best-selling and best-performing TVs over the past few years, combining a full range of smart and gaming features with superior picture quality, usually at a lower price than LG's OLED competitors.
LG's line of OLED TVs has impressed me throughout 2025. LG C5 five stars and a demotion LG B5 four and a half stars. LG G5Meanwhile, it received a five-star rating from TechRadar senior editor Al Griffin.
But throughout the entire period of parallel testing of various combinations of TVs over the course of a year, I never installed all three LG OLED displays next to each other, playing the same content – that's how it was until now.
Brightness
The biggest difference between LG's three OLED screens is their brightness. When we measured them, the G5's peak brightness was 2,268 nits, the C5's was 1,180 nits, and the B5's was 688 nits. Unsurprisingly, when we compared the three TVs, the G5 had the brightest highlights, and bright scenes like snow looked the brightest on the G5. The C5 still had good looks, while the B5 looked a little dull in comparison.
The G5's measured full-screen brightness in our measurements was also the highest of the three at 331 nits, with the C5 coming in at 199 nits and the B5 coming in at 172 nits. Consequently, content like sports, where full-screen brightness is important, looked the most impressive on the G5, while the C5 and B5 were closer than expected. Despite the difference in brightness, all three TVs had problems with mirror reflections due to their glossy screens, which is something to keep in mind if you're watching TV in a brightly lit room.
Color

Color reproduction on all three OLED displays is excellent. I'm watching The Sound of Musiceach screen showed a market scene with red and yellow fruits and vegetables. The G5 had the richest and boldest colors, but surprisingly I found the C5 to be very close. It was almost as bright as the G5, conveying the same vibrancy of the reds and yellows, as well as the green grass of the fields and trees throughout the film. The B5's colors weren't as vibrant as the other two, but they still looked accurate and vibrant.
Switch to MaskThe G5 was again the most powerful. Musk's yellow suit looked the brightest and most colorful on the G5, but again, the C5 showcased rich yet natural colors that easily competed. B5 again had great color, but it didn't look as vibrant as the other two.
In terms of color accuracy, the G5 and C5's colors looked the most natural, and skin tones looked consistently true-to-life. I found that the B5 had good accuracy overall, but there was a green tint that affected some scenes, such as at the beginning of the movie. The Sound of Music. The G5 and C5 easily capture the different greens and browns of the grass, while the grass on the B5 looks more uniform.
Contrast and viewing in a dark room
All three of LG's OLED displays delivered powerful contrast, delivering deep, inky blacks in high-contrast scenes with lamps set against dark walls and hallways. Dark City. The G5 had the strongest contrast due to its higher peak brightness, but both the C5 and G5 weren't far behind.
Due to the low overall brightness level, Batman It turned out to be an interesting test of these TVs under dark room viewing conditions. When Batman was investigating the crime scene at Mayor Mitchell's house, I noticed that the deep black on the G5 took on a grayer hue, but looked more accurate on the C5 and B5. Of the three, I found the C5 to be the most accurate, displaying high-contrast scenes as well as I'd expect.
Gaming Features
All three LG OLEDs earned a spot in TechRadar's rankings. best gaming tvs list. Each has four HDMI ports and supports 4K 120 Hz (and up to 144 Hz for C5 and up to 165 Hz for G5), AMD FreeSync and Nvidia G-Sync, HGiG, ALLM and Dolby Vision. Each also features 9.2ms input lag and features LG's Game Optimizer with customizable gaming settings. I tested Battlefield V on all three, and everything worked smoothly on each.
All three sets support webOS 25 and a number of its artificial intelligence features, such as AI Concierge and AI Search for content discovery. They also support the new AI Sound Wizard, which allows you to create your own sound profile using prompts, similar to the AI ​​Picture Wizard. However, thanks to the more advanced Alpha 11 processor, the G5 provides more AI upgrades, including Brightness Booster Ultimate and full 11.1.2-channel upmixing in AI Sound Pro mode (which I ended up using). Both the C5 and B5 boast AI upgrades, but the B5 doesn't have AI Sound Pro.
The G5 and C5 certainly benefit from the AI ​​Sound Pro mode, which added more precision and immersion during my testing, especially during the Batmobile chase. Batman. The B5's audio is a weak point, and while it's good for everyday viewing, it doesn't match the picture quality for movies.
Which LG OLED TV should you buy?
Which LG OLED is best for you will depend on your budget, although you're unlikely to be disappointed with any of them. For the money, however, the LG C5 is a better choice overall. It has good brightness, more than enough smart and gaming features, and picture quality approaches the G5.
For the 55-inch models, you'll pay $1,899 / £1,799 / AU$3,299 for the G5, $1,199 / £1,299 / AU$2,899 for the C5, and $899 / £1,099 / AU$1,799 for the B5. If you're looking for the best value TV of the three, the C5 is the one for you.
