you can think 'but thats inhumanly fast, you wont notice it' but in reality, this is _very_ noticeable in games like counter-strike where hand-eye coordination, speed and pinpoint accuracy are key. if you play such games a lot then you will feel it if the latency goes above 1ms.
It’s gotta be the most commonly mixed up things I’ve seen in the last twenty years as an enthusiast.
the part of feeling the difference in response times, that's true though, but I must say, the experience is a bit dated ^^ i see more high resolution monitors have generally quite slow response times.
<1ms was from CRT times :D which was my main counter-striker days. I do find noticable 'lag' still on TV vs. monitor though but i've only tested on HD (1080p) - own only 1 4k monitor and my own age-induced-latency by now far exceeds my display's latency :D
I still use CRTs :) However more than input lag, for me its motion. Which is driven by panel response times and I just cant stand even the best modern OLEDs for motion unless its 240hz and up.

Yeah you likely will to be honest. Most even average monitors will be single digit, 1-2ms maybe at most. Depending upon TV model, game mode may only get you to low double digits. High end panels should get you to pretty low single digits though, like 4-5ms.
Rtings basically gives you a number that represents average lag without screen tearing. If you measure at the top of your screen and/or tolerate tearing then the numbers get significantly smaller, and a lot of screens can in fact beat 1ms.
