There's a lot to like about 4K OLED TV technology. Seen as the worthy successor to plasma TVs, 4K OLED TVs offer many of the same attributes—rich, deep black levels, accurate colors, and nearly unlimited viewing angles—but with the slim profiles and high energy efficiency you get with LED LCD TVs.

LG's 4K OLED sets now top our TV Ratings in several of the larger TV size categories. (LG is the only company selling 4K OLED sets in the U.S. We've been waiting for other companies to offer their own OLED TV models, but that hasn't happened yet.)

LG is bullish on OLED, charging ahead for 2016 with eight new OLED TV models in the B6, C6, E6, and G6 series. All will be full-featured sets that support both HDR10 and Dolby Vision high dynamic range (HDR) technologies. They also support a wider range of colors than many basic sets, and include the company's webOS 3.0 smart TV platform with access to a number of streaming services.

Prices start at $4,000 for both curved- and flat-screen 55-inch sets and climb to $8,000 for the 65-inch model in the flagship G6 series. The price for the 77-inch OLED77G6P hasn't yet been announced.

4K OLED TV Tops Our Ratings

So just how good are OLED TVs? We just finished evaluating the 55-inch LG OLED55E6P, $4,000, an E6-series 4K TV that as of early June is the highest-scoring model in our TV Ratings. The television is pricey, but we think it will be one of the best TVs you can buy this year. It has outstanding HD and UHD picture quality and very good sound. And the vignetting issue we saw with last year's OLED TVs seems to be gone.

More details on the LG 4K OLED TV lineup for 2016:

OLEDB6P (flat screens) and OLEDC6P (curved screens)
These are LG's basic OLEDs for 2016. The C6 model has 3D and a curved screen, while the B6-series models have flat screens and no 3D.
Prices: $4,000 for the 55-inch models and $6,000 for 65-inch sets.

Available in 55- and 65-inch screen sizes, the E6-series sets are step-up models that are ultra-thin and sport a "picture-on-glass" design with barely any bezel around the edge of the screen. The TV comes with a Harman Kardon-designed sound-bar-style speaker system along the bottom of the screen, which in this series is flat, not curved.
Prices: As of early June, LG is running a promotion on this set, so the 55-inch model is priced at $4,000, and the 65-incher is $6,000—that's $1,000 off the usual cost.

OLEDG6P Signature Series
The G6 models represent LG's flagship 4K OLED TVs for 2016. There's a 65-inch model (OLED65G6P) that sells for $8,000, and later this year it will be joined by the 77-inch OLED77G6P. This model has a flat screen and the picture-on-glass design, but its Harman Kardon-designed sound bar speaker is a bit more powerful, and it's housed in the TV's base, which also contains all the set's connections. One interesting feature is that for wall mounting, the base rotates up behind the TV, with a second row of speakers facing out toward viewers.
