1 ms response time native vs non native

[WICKEDRANGER]

Hello, I bought an Acer XF250Q 240 hertz monitor with A 1 MS RESPONSE TIME  AT NATIVE 1080P (1920X1080). My question is if I have 400x400 resolution or lower like 300x300 at 240 hertz with my 1 ms response feature vs. my native resolution of 240-hertz 1ms response feature at 1080p, would there be a delay because I went non-native?  Also, it's advertised at 1ms response so does the response change even though it's a 1ms response monitor when I go non-native? thanks!!!

Response time is a measurement of how quickly the LCD itself can switch between two states, and it's independent of what image you give it. If there's any input lag, it's from the image scaler having to need to do scaling.

so does changing the resolution of 400x 400 at 240 hertz affect me in a negative way at all then? I didn't get your statement @M.Yurizaki

To answer your original question: no, resolution does not affect response time.

 

To augment that answer: using a non-native resolution may introduce input lag, but it likely won't be noticeable.
