If you think OLED technology has hit a plateau in terms of picture quality and color accuracy, the LG C6 might change your mind. The updated OLED panel delivers a brighter picture than its predecessor, along with a few menu tweaks to help you get the most out of your new TV.

Also: LG C6 vs. LG C5: Which flagship OLED should you buy?

I spent the past week putting the TV through its paces, including a suite of color, contrast, and brightness tests, and the performance was mostly impressive. Mostly. Let me break down why.

The LG C6 OLED TV is a respectable refresh of the brand's flagship model, featuring dedicated picture modes for live sports and gaming, Dolby Vision HDR, and Dolby Atmos virtual surround sound.

The slick, streamlined design hides a lot of cutting-edge tech that LG managed to cram into the main housing behind the incredibly slim ¼-inch-thick screen. The redesigned processor utilizes machine learning algorithms for automatic picture and sound processing tailored to your space, as well as manual fine-tuning for cine- and audiophiles who prefer to have total control over how their TV looks and sounds.

With seven preset picture modes to choose from, you can quickly change settings to suit your favorite media. Or if you prefer manual picture calibration, the advanced settings let you adjust everything from contrast ratios and white balance to RGB fine-tuning and gamma levels.
