Do 4K TV's run at 1440 and 1080 for gaming?

When I had my first 1080 TV, it would support 720 and 480 based on what I plugged in, and it still made everything look way more awesome on my previous TVs. I understand native resolution means the maximum resolution, i.e. the resolution is was meant to be used in, but I often hear people say, games and movies will look like crap on a 4K if not in its native resolution, yet in my minimal experience, my TV's and Monitors did just fine doing any resolution under native as long as it was 16:9. My native QHD monitor, it looks like a normal 1080 screen when I lower the resolution, and if I force QHD+, I do notice less detail but its still looks fine.

I was wondering if these 4KTV's are made to do 1080 or 1440, or just any other 16:9 resolutions, or does everything just get upscaled to 4K?!? And if you choose one of those options, does the TV still fit the screen without making it 4k?!?

Like if a Steam Machine/HTPC like device was plugged in a monitor it could run at 1440, what would happen if plugged into a 4KTV?!? I was assuming it just does what it would do with a console, and just upscale the 1080 to 2160, except the graphics card doesn't really have a set resolution, or does it?!?

When you use it, if you're using it for a computer, you can always edit the resolution in 'Screen Resolution' so it will run it. So yes, it does allow lower resolutions.

yes they support lower resolutions. TVs can support more lower resolutions than computer monitors.

Sweet, yeah I'm looking at getting a 4K for awhile now, but originally was just gonna be for movies, but realized you needed 4K gear. I figured since I don't want One S or PS4 Pro, if I did get one, I could just use my little LAN box on it. I guess I should have known people just talking crap on internet, people probably didn't even have a new TV.
