Very good but with reservations on some points.
I've printed the complete doc (380 pages!), much more practical than going through the screen help, especially since each page has 3 or 4 indexes that link to other pages.1/ The image is clean with the antenna in 1920p. For the same channel with the TV box connected in HDMI (obligatory), the colours are bad, passed by the corrector of tint to correct (not completely).Not yet had time to go in the advanced parameters of correction of image, a true factory with gas (gammas, separated RGB, blacks, etc...) 2/ Why the TV passes in 4K in box TV? that smoothes the faces, kind Grévin museum, and not means of deactivating to return to 2K (1920p). It updates the signal automatically, so TV by antenna is much more beautiful.3/ A good point for movies in 4K with filmmaker, when even made qq retouches videos (sharpness, light, contrast) everything is at full 90
4/ The files (audio, video) supported, it's a DISASTER!!! in audio, no DTS, just Dolby (AC3,E-AAC...), obliged to go through a converter (DTS to AC3) in the PC for 4K movies downloaded on the PC which are in DTS at 90%.5/ Subtitles: Unicode(UTF8) not supported, again forced to go through a converter (UniConverter) on the PC to put a supported format:".srt , .sub , .txt "6/ In 2020 (TV release date), the formatting in .NTFS absent, pitiful! I had to format HDD and USB keys in exFAT .-----------------------------------------------------------------------------------Less important: the remote control could be backlit at this price, especially when you're watching in complete darkness. The buttons are too close together, you press buttons next to them if you're not careful, but no big fingers. ---------------------------Thanks for reading...maybe not to the end.
