However, PCworld today wrote that, even in 2017, the LG new 4K TV UJ6300, UJ6500, UJ7700, UJ8000, the real resolution is only 2.8K.
This problem they attacked a year ago, however, editors bought a new TV and neighbors of non-LG 4K TV put a contrast, found that playing 2160P resolution standard video, LG display quality is to almost mean .
The problem lies in the sub-pixel arrangement, LG is using the standard RGB array on the OLED, horizontal pixels 3840, RGB three-color area consistent. LCD TVs use the RGBW arrangement, and the purpose of introducing white is to increase the brightness.
In the RGBW arrangement, white does not participate in the color rendering, so it is sacrificed by 1/4. The horizontal actual pixels are only 2880, in other words, only 2.8K.
PCworld suggests that if you don’t basically touch 4K’s media resources, then LG’s pseudo-4K LCD TVs will be purchased. Conversely, consider carefully.
