m17 R3, 4K panel, 25ms response time measured how?

Well I mean it’s pretty noticeable if you had a 45ms response time because I use my OLED C9 with my X51 R3 and the GTX 1660Ti.

25ms isn’t that bad, but for gaming the colors and contrast are far better but the refresh rate and the response times are slower.

4K 60Hz > 1080p 300 or 144Hz If your a Graphics designer

4K 60 < 1080p 300 or 144Hz if your a Gamer.

But is it 25ms black to white response time or 25ms grey to grey response time? ANd would there be noticeable motion blur or ghosting when playing csgo.

But will csgo be playable on the 4k option, will there be motion blur or ghosting in fastaction movies or games? And will a crosshair in games appear fast enough on the screen to where I point it, so that I shoot exactly to where the crosshair points if I were doing a flick shot would the crosshair appear fast enough to where I flicked for me to be see if the crosshair is on target to shoot and be accurate?

You won’t notice it in games or movies but I’d opt for the 1080p 144hz option.

Is input lag bad on it or its far better than the 25ms response time?

The 144hz option is the best for gaming for its 7ms response time over the 4 60Hz.
