[Monitor] Response times specifications GtG MRPT

Hello there,

I'm looking to buy a new monitor, currently looking at the "Optix MAG274QRF-QD" and the "Optix MAG275R", the question that goes through my mind while I look for screens is that seems that every RAPID IPS screen has 1ms GtG while normal IPS screens got just 1ms.

So I'm wondering if the non rapid panels allow for a 1ms MRPT while rapid pannels only allow for 1ms GtG, but that indeed would make the "rapid" panels less rapid so it makes no sense..

Do you know if there's a way to compare response time MSI monitors in MRPT measurement?

EDIT: Looks like in the spanish version of the website of the "Optix MAG274QRF-QD" they say it has 1ms MRPT, but they said nothing about it in the english version:

Now the question is if the english version of the web has missing info or the spanish version wrong info...

I don't know about the difference between GTG and MRPT, but hardware unboxed does monitor reviews, and has pretty solid info regarding response times, and cumulative picture error from things like transition overshoot and slow transitions. The MAG274QRF-QD has some of the best response with low error.

MRPT = also known as MPRT Moving Picture Response Time (how quick it can refresh the actual Pixels from motion)
GTG = Grey To Grey how fast they can turn from grey to black and back to grey

there just 2 ways to measure the response time.

Tr + Tf is the hard one for any screen and is the newer one that is from Black to White and Back to Black and is always much slower usually between 8-40ms so that screen is on the faster side.
