I traded for a 7 year old LG LED 55". Switching to the new TCL 75" absolutely no problem. Watching from about 2.5 - 3m away, I got used to the screen size in no time. FullHD signal reception is the bare minimum for a 75", otherwise you'll see a bit of 'dicing at a worse signal source: ) better to play only very high quality FULLHD or 4k. The picture with Full Array Local Dimming (128 dimming zones) is definitely noticeable. As proof, if you, for example. on youtube you can watch a video designed mainly for OLED TVs, where mostly on the black background there is some object etc., you can see a very big difference compared to the usual local dimming of LED screens. The image is excellent in any lighting conditions. The Onkyo 2.1 sound with Dolby Atmos support is a cut above, somewhere else in fact, than a regular TV with ordinary sound. with sound. Those who can salt up the volume up a bit at home in the living room, don't hesitate at all. Switching from LG WebOS to TCL Google TV 12 (formerly Android TV), also no problem at all. But you need to play with it a bit, unlike webOS. If you require absolute speed of system control instead of the classic one, you can activate the developer mode, in which you disable the three options for window transition animation + max. 2 running processes in the background. Other specialties that you won't read anywhere are:
-- When you turn off the integrated microphone on the TV down next to the power button, the yellow LED on the TV then lights up in the TV on state and there is no way to turn it off, but it is a small thing that does not disturb or you can leave the microphone on and you are done.
-- If you want to use the handsfree with integrated microphone on the TV, you need to enable handsfree in your google account in the TV settings, but this option is only available if EN language is set in the TV system, but then again google voice recognition can't recognize Czech phrases anywhere in any app or system, you say ok google Křemílek a Vochomůrka and it finds absolute nonsense, so you can't search much in Czech, and if you have CZ language set in TV, so handsfree with integrated microphone can't be used, but again voice recognition when searching when you click on microphone icon in youtube and other apps or via button on controller is on point.
-- I've spent the most time testing different video players and the best sound and picture and speed and simplicity is the built-in (pre-installed) Media Player(media center), it can also do Dolby Atmos, but it has a major drawback, it doesn't adjust subtitles(color + position) and it doesn't even take over from the subtitle settings in the TV system, which I consider a mistake, so you have subtitles in the picture even if there is a black bar under the picture, where they should be by default, which other players (Kodi, Nova video player, Just player, etc. ) can automatically. And it also can't play some avi formats, however I only play from a flash drive and only mkv or mp4 so it doesn't matter. You can't play from the net with it either, but I don't use that either. I don't really recommend VLC, because it eats up system resources unnecessarily and sometimes my movie playback was a bit slow. Just player doesn't eat anything, it has subtitles under the picture (it takes the color from the system settings), it's fast simple, it can do Dolby Atmos, but it also can't do avi, and the menu for selecting from the disc is terrible. KODI's a bit of a system hog, too. Finally, I use Nova video player (but it doesn't support Dolby Atmos) for subtitled movies and the default Media player for dubbing.
-- In the picture menu, I consider the "Cinema mode" option as the ideal choice for everything -- I turned off the intelligent audio playback according to the conditions around the TV and the sound source, it didn't seem very good when I tried different shows, movies, songs, etc.
- On the other hand, I left Smart Playback on
-- I've turned on the "My apps only" option in the google account settings on the TV to better optimize it so that google doesn't keep cramming its stuff in and when I need to download something or check for new updates from google play etc. so I turn the option off, download/update what I need once in a while and turn on my apps only (in "my apps only" mode voice search via the controller doesn't work, but directly in apps via the microphone icon it does)
