LG’s OLED TVs are often among the best TVs I test each year, and 2026 has been no different. Both the LG G6 and LG C6 earned full five-star ratings in my reviews, while the LG B6 also earned four-and-a-half, proving itself to be a fantastic affordable option.

On paper, all three of these TVs share a lot of the same features, especially for gaming, and they all scored highly for their picture quality, but how do they compare alongside one another in a real-world setting? I conducted this same test last year with the LG G5, C5 and B5 and in that instance, the LG C5 was my top pick, with the best balance of price and performance.

I’ve already compared the G6 and B6 this year, but now that I have access to all three TVs at the same time, I couldn’t wait to do a real world comparison between the three. The C6 has a new built-in processor (the same Alpha 11 AI Gen 3 the G6 uses), the B6 I tested hit new brightness heights and the G6 delivers even more impressive colors than its predecessor. All three still have big shoes to fill, so let’s see how they compare.

A quick note: I’m using the LG B6E here — a more affordable version of the LG B6 that I used for my review. While there is a price difference, LG has told me they are fundamentally the same TV; the B6E is missing some remaster features and has a plainer back panel, but still has important features such as Dolby Vision and the same gaming features.

Colors

The best OLED TVs often produce rich, vibrant colors that add real depth to a picture, and all three of these 2026 OLED TVs do the same across the board. Watching The Super Mario Galaxy Movie, the colors rendered on all three screens are stunning. The red and green of Mario and Luigi’s hats and overalls are both punchy and lifelike on each TV, and in this scenario, there’s not a lot to choose between them.

Any time the Lumas are on screen, there’s gorgeous visual pop with seriously bold colors on all three TVs, but this is where differences started to show. While there was a nice vibrancy on all three TVs, the G6 demonstrated the richest and brightest colors thanks to its higher peak brightness (more on that in the brightness section). I was surprised, however, at just how close to the G6’s colors were to those of the C6. The Lumas had the same color depth and luminosity (pun intended) on both.

Switching to another colorful movie in Speed Racer, all three TVs again accurately delivered super-saturated, vivid colors throughout the movie. The bright decor of the Racer home, with its orange and blue walls, really explodes on screen and again, the G6’s brightness gives its colors the most outright impact. Clothing, such as Speed’s blue shirt and Pops Racer’s red and orange shirts, are vibrant with plenty of visual punch.
