The manufacturers do not stop launching specifications of gaming monitors, that if contrast, that if pixel pitch, that if curvatures… To the point that the common user does not understand what they are talking about and at best, the average gamer will have heard terms like GTG or MPRT to assess the speed of the monitor. For some time now, the first part has been discontinued to focus on the second, therefore, today we will know in depth what MPRT is.
To measure whether a monitor is really faster than another for gaming there are a number of factors that must be measured onsite, but this exposes manufacturers to a comparison where they do not want to participate and which is only used in the corresponding reviews.
Until recently, they provided a value that was very controversial and that we will deal with in another article such as GTG, but currently the trend has moved towards another parameter that is more representative and “faithful” to reality.
MPRT: A Better Way to Measure Response Time
This parameter is born as an acronym for Motion Picture Response Time and as its translation treasures, it refers to the response time of a moving image, or more technically said, it is the time in which a pixel is visible . Here the theory is basic: the slower the response time, the more blur of the movement of an image we will have on the screen.
This is very important for gaming monitors, where images are succeeding each other at higher refresh rates and therefore more refreshments are performed at the same time on the screen.
We can check the effect in the BLUR Busters motion tests .
If the response time is very high and the FPS rate on the screen is also high, what we will have is precisely some movement changes that will leave a kind of trail in the worst of them or a lack of sharpness in the least.
This is caused by the fact that MPRT is clearly limited by the duration of the update cycle of each panel and by the frametime .
Therefore, manufacturers use MPRT to the detriment of GTG, because the former measures the time that this blur / blur or trail lasts.
The MPRT unwritten rule
There is a rule that you will not see in any technical document, whitepaper or similar, since it is something that the professionals of the panels have always commented on and the professional players have ended up accepting.
This rule states that the MPRT of the monitor has to be at least 4 times less than the rendering time of the graphics card for everything to flow as it should. This rule takes into account the input lag of the panel in general terms, since everything accompanies adding rendering time and change on the screen.
So, on a monitor with 1 ms of MPRT, the minimum rendering time of the graphics card must be 4 ms, or what is the same, 240 FPS. Therefore, panels with such hertz are usually 0.5 ms today, achieving better results than those of 1 ms.
Likewise, MPRT is not the only value that we will have to look to buy a gaming monitor, most of the timming of both the panel and the pixel matrix are not specified , so we will have to look at the corresponding reviews that treasure them in order to make us an idea of which monitor is better.
