![]() ![]() The C8 measured the best gamma of the three after calibration, coming closest to my BT1886 target, which might explain the difference. In Chapter 7 the shadowy machinery behind Thor looked a bit lighter on the E7 and the Sony compared to the C8. The three OLED sets looked almost identical in most scenes, but I did notice slight differences in shadow detail. Brighter scenes in Asgard levelled the playing field between the TVs more evenly later on. The dark scenes, such as Thor's initial confrontation with Surtur in the beginning or the lights against the dark screen at the beginning of Chapter 7, for example, exhibited the OLEDs' advantage well. The 2018 C8 didn't look any better overall than the 2017 OLED models, the Sony A1E and the LG E7.Ĭomparing the Thor: Ragnarok 1080p Blu-ray between the six TVs, the OLEDs showed their typically perfect black levels in the letterbox bars and correspondingly darker shadows, which improved contrast and impact over the LCDs. As usual OLED dominated in a demanding home-theater environment. Overall C8 is very slightly better than 2017 OLED TVs, but they all deserve a picture quality score of "10".Ĭlick the image at the right to see the picture settings used in the review and to read more about how this TV's picture controls worked during calibration.ĭim lighting: This category was an unfair fight between the three OLED TVs and the three less-expensive LCDs. ![]() The impact of LG's Alpha 9 processor is minor, but LG added the ability to tweak some settings (such as HDR remastering), as well as including black frame insertion (which isn't worth the trade-offs in my view). Video processing is excellent but still falls short of some TVs' motion resolution. Off-angle was better than any LCD, and uniformity superior to any OLED we've tested at CNET - including the 2017 models in this comparison. It evinced perfect black levels and best-in-class contrast, as well as superb color accuracy. With both HD and 4K HDR sources, in bright rooms and dark, the LG C8 delivered the best picture I've ever tested. See the picture quality section below for more details.Ĭlick the image above for CNET's picture setting recommendations and other details. LG also added black frame insertion to all of its 2018 OLED TVs, including the B8. The company claims the chip improves noise reduction, sharpness, contrast and color (the latter with superior color mapping). ![]() LG's 2018 OLED TVs have the same light output and color gamut capabilities as 2017 models, so the biggest picture quality difference is that the 2018 TVs (aside from the B8, due later this year) get LG's new Alpha 9 processor. That's why OLED and plasma are known as "emissive" and LED LCD are called "transmissive" displays, and a big reason why OLED's picture quality is so good. LCD relies on a backlight shining through a liquid crystal panel to create the picture, while each individual sub-pixel is responsible for creating illumination on OLED and plasma screens. OLED's basic tech is closer to late, lamented plasma than to the LED LCD (QLED, quantum dot or otherwise) technology used in the vast majority of today's TVs. ![]()
