Picture in picture mode Smart TV?

I wouldn't ask here now if I haven't looked anywhere myself.

to the question:

is there still a TV or Smart TV that has picture in picture mode on board?

I'll explain that in more detail.

and I want to gamble on one half & watch a Twitch stream on the other half or watch a YouTube video.

best 4K should have the TV.

moreover. I had a television 8 or 9 years ago, but it could only do a FullHD & 'could only show different channels on the screen in TV programs, I think a plasma was that…

Thank you in advance for your help.

Unfortunately there's no television or the hardware was not yet supported so that the manufacturers did not continue to produce it

so I don't know, but no
