Ok maybe choosing an input and perhaps volume control and an off switch - but even that's more than I'd like it to have.
Samsung TV's in particular I find very puzzling. Why does it insist on changing modes? Why does it need to log me into a Samsung account? Why can't it find it's own upgrades? Why on earth does it slow down and need rebooted after using some "apps"? Why on earth does it have "apps"? And dear deity in a lulzbucket - why does it put red splodges everywhere?
And that's one of the countless reasons why I don't buy and use any device titled "Smart" or has unique features similar to them. They can range from smart-TV's, smart-watches, smart-thermostats, smart-clocks to... smart water? Anything. (Sorry, advertisers tracking me, that I won't ever buy stuff that'll help you infringe my privacy even more.)
If you are just going to use it as a panel, they are pretty good! Even the cheaper 8-bit panels are quite tasty, as long as you don't pretend to get HDR out of them.
It's just the "smart" part that is more than a bit silly. I've got mine setup with a Chromecast as it's default gateway, so the "smart" can only do a whole lot of nothing.
After many factory resets and jiggling with settings, reinstalling drivers and all sorts of unnecessary fun I finally have 4k on PC working again
Half the video modes have gone though, HDR+ no longer works (no big loss on this panel) and the YouTube app is knacked beyond belief - but none of that matters for my useage.
PS4 and XB1 now default in "game" mode for some strange reason (it never did this before) and the annoying red blobs have (so far) not turned up.
I was <that> close to taking the silly thing outside and putting some nice 9mm holes in it.
