All monitors have input lag, and TV's generally have a much higher input lag - the best / lowest input lag TV's are some specific Sony models, and they already have 18 ms input lag in Game mode.
This is also why many gamer monitors are still TN panels, TN has the lowest input lag of all LCD tech.
This 'tidbit' of information is widely documented in pretty much every decent monitor and TV review.
Look if you post questions regarding sensible advice you can't just 'skip' the price argument. Of course it is a good idea to have a look at the current state of the market and recent developments, and base your choice on that. If you just want to throw a crapload of cash at something, you don't need advice. You need a salesman. Nobody is telling anyone not to buy stuff, but what I am saying is that buying into 4K at this point is an expensive hobby that will see significant price reduction in the coming year, and that single GPU still can't run 4K comfortably. So is it a smart buy? No.
If you feel it is something you want that's fine, but don't tell yourself it is the best choice to make right now because it really isn't. In the same vein nobody would recommend you to go quad SLI two years ago just so you could run 4K, yet I am sure there are people that have done so.
And I am telling you that idc what your information says.
Gaming in 4k looks amazing..
Sounds like more of the "The human eye can't see more than 30 fps" nonsense to me..
Looks amazing, runs like a charm..
Smart buys? lol..
Those exist? People who have expendable cash, upgrade when they feel like it.
All this talk about "smart buys" is a bit silly to me..
There are no smart buys, you just buy when you want too, when you feel like it..
Significant reduction in prices are already here.
My 4k 50" costed me exactly what my 1080p 50" costed me..
The prices have come down a ton..
You keep waiting, I'l stay at the edge of gaming technology, where I like to be.
Which by the way has me currently gaming in 4k, in games like Metro 2033 and star citizen.
Takes two of my cards though.
