If you were among the many viewers who just couldn’t quite make out what was going on in the battle scenes of “Game of Thrones” a week or so back, you still have time to upgrade to a new 4K TV before the whole saga comes to a close. Here are the best performing sets that CNET has reviewed over the last year.

LG OLEDB8P series

CNET rating: 4.5 stars out of 5 (outstanding)

The cost: $2,500–$3,299

The good: The LG B8 has spectacular image quality, second only to LG’s more-expensive OLED TVs among models we’ve tested. It delivers perfect black levels, superb uniformity, wide viewing angles, accurate color and a great bright-room picture. Its striking design features a super-slim panel.

The bad: It can’t get as bright as competing LCD TVs.

The bottom line: LG’s entry-level OLED TV doesn’t compromise picture quality.

TCL 6 series (2018 Roku TV)

CNET rating: 4.5 stars out of 5 (outstanding)

The cost: $820

The good: The relatively affordable TCL 6 series has excellent overall image quality, with deep black levels, very good brightness, rich contrast and accurate color. Its Roku smart TV platform is the best available, with a simple interface and extensive streaming app support. The TV handles both HDR10 and Dolby Vision high dynamic range sources.

The bad: Brightness and video processing fall short of some more expensive TVs.

The bottom line: With superb picture quality that rivals TVs costing twice as much, TCL’s 6 series is the best TV value we’ve ever reviewed.

LG OLEDC8P series

CNET rating: 4.5 stars out of 5 (outstanding)

The cost: $2,797–$3,499

The good: The LG C8 is the best performing TV we’ve tested to date. It delivers perfect black levels, wide viewing angles, accurate color and a great bright-room picture. Uniformity and video-processing options are slightly better than last year. Its striking design features a super-slim panel.

The bad: The C8 is expensive. It can’t get as bright as competing LCD TVs.

The bottom line: LG’s C8 OLED TV sets the standard against which all high-end TVs will be judged.

LG OLEDC9PUA series

CNET rating: 4 stars out of 5 (excellent)

The cost: $3,500

The good: The LG C9 OLED TV has better image quality than any television we’ve ever tested. It delivers perfect black levels, wide viewing angles, superb uniformity, accurate color and a great bright-room picture. Video processing is slightly better than last year. It adds HDMI 2.1 features and support for Amazon Alexa and Apple AirPlay 2. Its striking design features a super slim panel.

The bad: The C9 is expensive, and 2018 OLED TVs perform almost as well for much less money. It can’t get as bright as competing LCD TVs.

The bottom line: If you want the best TV picture quality and are willing to pay for it, the LG C9 should be the first 2019 TV on your list.
