Having just gone through this...it's a lot harder than you think.

Current gen TVs have specs that garden variety connect a computer can't supply over HDMI. You need HDMI 2.1 with FRL to hit it. So you climb onto google, discover yes there are minipc that can do that...except only the new ones...the "AI" ones that cost you an arm and a leg. Also they need fast DDR5 memory which is great fun right now. And the more affordable ones are AMD so no quicksync.

So you think lets maybe do a USBC dongle to an existing device, only to discover that they require different firmware (!) on the dongle depending on whether you're using a mac or a windows PC [0]. And then you realize you actually need a cable capable of 48gbps and none of the ones lying around are labelled so you have to buy a new one just in case. And after you've done all that you still don't know why its connecting at 120hz not 144hz per TV specs. And then the whole media encoding circus starts...

I can 100% understand why people just type in wifi password and call it a day. The average consumer is not up for flashing firmware onto dongles to watch their big brother series.
