Almost all televisions use a form of semi-glossy coating, which is the worst type of non-matte coating since semi-glossy coatings make black looked greyish, and displays look washed out under bright lighting. Some semi-glossy coatings are worse than others, and the 43X750F's coating is one of the least desirable types of semi-glossy coatings, especially since this panel is not very bright. The first photo is of the 43X750F with my ceiling light turned on, and with 140cdm/2 display brightness. Here it is with the ceiling light on and maximum brightness of 272cdm/2:
Photo of the Sony with my bias lights (3x LIFX BR30's set to 4000k and maximum brightness) and 140cdm/2 display brightness (17/50 menu brightness) versus the ceiling light:
Bias lighting (lights placed behind a display) is highly recommended since the 43X750F is not very bright, and because its semi-glossy coating makes it look washed out under bright lighting.
