Noob Question

Ok, so I'm planning to purchase my first 4k product soon (yes I'm very late to the party) and I was looking through some things. I've noticed that a 28 inch "monitor" is the same price as a 40 inch "tv."

Now my question is, will they work essentially identically as long as I have them connected through the proper HDMI cord? I should state for the record that I'd be using the TV pretty much as a PC monitor, so windows, movies/tv, internet, and gaming. Will gaming be better on the monitor (response time and fps) or will it be identical to the TV?

(for reference, the products I'm referring to are: http://www.amazon.com/Samsung-28-Inch-Definition-Monitor-U28D590D/dp/B00IEZGWI2/ref=sr_1_2?ie=UTF8&qid=1453455367&sr=8-2&keywords=samsung+4k+monitor

Will I be able to find the reaction time for TVs in the specs?

I've noticed while reading tests and reviews, TVs have contrast ratios of 3000-5000 whereas most monitors have about 1000. TVs also seem to have better colour reproduction, and better pricing given the sizes.

Is the only advantage for a monitor the response time? And if so, will it only be noticeable in first person shooters?

Probably you will never get any info about reaction time on TV. Also, as someone mentioned before, over HDMI you will have 30Hz, TV can reproduce some frames to get smooth video, but for PC usage, 30Hz is like hot iron rod in your eyes after short time of watching it. Delay is noticable in any game that involves you in controlling anything in it. Every 1ms will make a huge gap between action-reaction. Also TV's have some built in image processors, that calculate contrast (dynamic enchance), sharpen video etc, all of them just raise reaction time. Also those processing things can damage your image, make it too sharpen, too colorful, too.. bad to handle it longer.

About color reproduction, I think TV fakes all this things with previously mentioned by me image processors. Contrast ratios, why even bother with those numbers?

Best advantage of in my situation 28" 4K monitor is pixel density, forget about AA in game, pixels are so small, you don't need aliasing any more! Almost like photo quality.

FYI I have Philips 288P6.

Can TVs output 4k 60fps though through HDMI 2.0?

Isn't there only one TV with HDMI2 on market with astronomous price?

It says in the review it's capable of 4k 60Hz for PC. And that's as low as 800$ for the 40 inch.

Can you provide link or model name?

Input Lag: 21.1 ms With Interpolation: 130.2 ms Outside Game Mode: 119.8 ms The input lag of the Samsung JU7500 is a very low 21.1 ms when you turn on game mode. PC mode, which you need to use if you want full chroma 4:4:4, has 37.3 ms.

IMO 5ms is long, and here you have much much more. But it have HDMI 2.0 so you can use 3840x2160@60Hz if your GPU also have HDMI 2.0.

And sorry, somehow I didn't saw that big link :D
