Which TV has a built-in browser that supports the maximum number of video standards?

Question

Browsers

You need a TV with a diagonal of 50 ", capable of launching a browser out of the box and playing the maximum video formats from the web, and also not beeping after half an hour, as some TVs do when they run out of buffer / ram or something else that limits the size of the video being warmed up;
I am also considering a flashing or, if the TV is suddenly a pure android ... - then point it with your finger)
Thank you
