Can you play games at 1080p and 2k on a 4k television?

Games from what, a PC? What television? Details :)

Sure you can.  However it will depend on how your TV down scales to lower resolutions.

Yes, from a PC to television. No idea which 4k TV to get at the moment. but I was just trying to figure out if this could be done with certain sets. @Digikid1 seems to think it can, but I will have to look at a few televisions first. The other thing I need it to do is play in full screen because I want to upgrade to a 55" screen. I think I might go with an LG television this time as the input lagg on them seem good across most of their televisions..

Would there be anything bad I need to lookout for on a television I'm want to use for a PC? Cheers!

I don't see any reason unless we have a serious regression about TV features. Never owned a 4K TV but all FullHD TV I owned was able to play games at lower resolutions (even 640x480) keeping fullscreen display (sometimes at cost of different frequency).

I hope Redrizla you post your impressions once you see some decent 4K footage or gameplay and compare to 1080p. It's quite staggering and once you convert you will wonder what the hell you were doing with 1080p content.

 :D 

@Shadowmask72 - Yes and I'll be honest about it. I haven't actually seen what games are like in 4k, I've just listened to other people saying you can't tell the difference on a 42" Tv at 1080p. I have seen some 4k films though and can tell the difference, so I am starting to wonder now..

Problem then is, can I get by with a Geforce 1080  :/

@RattyUK - I've got a 1080p monitor that runs at 144hz and it was great when I could actually sit in front of it without any problem. Now my back starts to ache and I can't get a decent pair of glasses without the monitor hurting my eyes. Now decided on an armchair and Tv for gaming, rather then hunched over my desk looking at a 27" monitor..

All that smoking can't be good for you either. Anyhow blues man were always better than reds. Then they made those really fine ones in a golden brown packet which I swore by back in the day.

Up until 2 or 3 weeks ago, a 1080 was the best card on the market. Dude, people have been using way older and worse graphics cards to run 4k content for YEARS already. A friend of mine still runs two GTX760's in SLi and uses plenty of 4k content. If you don't know if you can run it, then maybe you shouldn't buy it without doing more research for yourself...
