Isn’t a full HD resolution ( 1920 x 1080 ) almost four times less pixels than 4K ( 3840 x 2160 )? I think I understand that a higher bit depth gives me more information per pixel, resulting in for instance less banding, but I still expected my 1080p 10-bit video files to look very soft and literally low-res.
There is still some upscaling going on in the TV.
It would have to upscale, otherwise it would have to leave some pixels blank.
You mean, it stretches out the image to fit the 42 inch screen?
The other person told you the same thing, but basically for every one pixel, it will generate four pixels that are exactly the same as that one pixel would be.
It turns a one by one array into a two by two array.
There’s probably also some tech wizardry going on on the processor in the TV itself that is built in by the manufacturer.
