Monitors/TVs - High refresh rates

Hi Guys,

I know, yet another thread about high refresh rates, but currently I am confused by few facts, which embrace this topic, so let's start...

I would open this threads with a few opening questions:

Question No.1 - TV vs. Monitor panels - despite monitor technologies, is there (in terms of functions) any difference between, let's say 120Hz panel in the conventional gaming monitor (again, ignoring the "gaming" functions/features) and 120Hz panel (directly refresh rate of the panel itself, not marketing between-frame simulation) ?

Let's make it more interesting and let's focus it towards 4k panels, so 4k 40" monitor, like
http://www.tftcentral.co.uk/reviews/philips_bdm4065uc.htm
and some 4k TV with 100/120Hz panel, as an example
http://www.hdtvtest.co.uk/news/tx50cx700b-201506054122.htm

I always thought, there are well known limitations - interface bandwith (which means barely HDMI 2.0 and DP 1.2 with no problems for 4k@60fps) and actual capabilities of the HW to be able to push enough of frames

So, let's imagine we have in some particular game 40fps, will I find an image more fluid on the TV with 100/120Hz panel even if it at low fps and TV has at least about 50% higher input lag ?

Question No.2 - Do/Must every panel with particular refresh rate have exactly at least the response time value as from the recent table from tftcentral's article about OC of monitors?

Refresh Rate (Hz) Refresh Interval (ms)
60 16.66
75 13.33
100 10.00
120 8.33
144 6.94
165 6.06
200 5.00

Does Refresh Interval states for Response time (G2G) ? Or is the Refresh rate and interval something different than the Response time ?

So, what I am trying to find out, how do the user benefit from the high refresh rate panels (and what are their possible added values), when the fps is not high enough ?

But now and recently, I have got in a tiny fight with one of my "community" colleagues, where my choice has gone to the Philips monitor and his choice (as the example of better and cheaper choice) was Panasonic mentioned above, and after reading amazing posts by you, guys here

I have come to seek for more wisdom in this field and to be honest, I had problems fully understanding explanations in that thread.

At the end, if you would be as a person of an interest and you would get these two recommendations (as you want something bigger, than 32" 1440p display), what would be your pick ? Do you think, that TV would be better "bang for the buck" ?

Thank you all for your answers. 😉
 
Since no one else has answered, here's as much as I know:

1) A 120Hz TV should work at 120Hz just the same as a monitor. You just have to be sure that the TV can actually accept a 120Hz input from a PC. No current 4k displays will accept a 120Hz input, because that requires DisplayPort 1.3

2) Refresh interval and response time are different. The refresh interval is how often the monitor tries to change the colour of a pixel. The response time is how long it takes for the pixels to actually change to the new colour.

High refresh rate is beneficial because a) it reduces sample-and-hold motion blur (which accounts for the majority of motion blur in modern monitors), and b) it reduces latency (because each frame has to wait for up to a whole refresh interval before being displayed). If you're comparing 40fps on a 60Hz vs. 120Hz monitor, then only b) is applicable.
