A person familiar with the matter said that the 4K resolution of LG LCD TV is actually a lie. Some people have confirmed that the real resolution is actually only 2.8K.
LG is the second-largest manufacturer of TV sets worldwide, and unlike Samsung, it is brave to deploy large-size OLEDs. However, PCworld wrote today that even in 2017, LG's new 4K TV UJ6300, UJ6500, UJ7700, UJ8000, the real resolution is actually only 2.8K.
This problem they attacked a year ago, however, the editor bought a new TV and the neighbor's non-LG 4K TV put a contrast, found that playing standard video of 2160P resolution, LG showed the picture quality is almost meaning .
The problem lies in the sub-pixel arrangement. LG uses a standard RGB arrangement on the OLED, and the horizontal pixel 3840 has the same RGB three-color area. The LCD TV uses an RGBW arrangement, and the purpose of introducing white is to increase the brightness.
In the RGBW arrangement, white does not participate in color representation, so it sacrifices 1/4, and the actual horizontal pixel is only 2880, in other words, only 2.8K.
Xiaobian suggested that if you basically do not touch the media resources above 4K resolution, then LG's pseudo 4K LCD TV will be bought casually, and vice versa.
