This new MPRT indicator test is based on works of Josip Reponj & RTINGs, plus enhancements by Blur Busters with an optional multi-row version optimized for end users. As the graphics scrolls sideways, display motion blur from persistence will thicken vertical lines to overlap each other.

Instructions: Your MPRT is the pair of vertical bars that touches edge-to-edge without overlap or gap. If all lines has a gap, please increase Pixels Per Sec.

MPRT stands for Moving Picture Response Time. MPRT is also known as display persistence. It is covered in many scientific papers on Google Scholar. Also, MPRT is not the same thing as GtG. As seen in the GtG versus MPRT FAQ, GtG is the pixel transition time, while MPRT is pixel visibility time. MPRT can still create a lot of display motion blur even if GtG pixel response is instant 0ms. MPRT is generally a more accurate representation of visible motion blur blur (see Eye Tracking Motion Blur Animation demo). For the scientifically ideal instant-response sample-and-hold display, MPRT is exactly equal to the time period of one refresh cycle.

When GtG is zeroed out, MPRT is pixel visibility time of a frame. Thus, MPRT is pulsewidth on a strobed display (assumes squarewave impulsing, framerate=Hz), and MPRT is frametime on a sample & hold display (assumes GtG=0). See comparision diagram of MPRT on sample & hold dislay versus strobed display. An impulsed display is simulated by TestUFO Black Frames Insertion Animation), to see how flicker can shorten pixel visibility time, and thus reduce display motion blur. For more information about display persistence, see Blur Busters Law.

• The slower the motion, it is easier to track, for measuring MPRTs via eye tracking or camera tracking (pursuit camera).
• The faster the motion, it is harder to track, but becomes possible to see visible differences between smaller MPRTs.
• Adjusting your browser zoom setting is acceptable to make testing easier, but avoid zooming too big, or zooming smaller than 1:1 pixel mapping.
• The higher resolution the display is (4K and up), the longer faster-moving (in pixels/sec) stays onscreen, and becomes easier to measure lower MPRTs.
• Higher resolutions amplify the visible clarity difference between static resolution and motion resolution.
• This is why higher resolutions demand higher refresh rates and lower MPRTs, thanks to the Vicious Cycle Effect.
• Some motion blur reduction technologies (e.g. ULMB2) advertise a "1440Hz equivalence" = 1/1440sec MPRT.
• A refresh rate equivalence is the inverse of MPRT, and is generically called a Motion Clarity Ratio (MCR), equal to 1000 divided by MPRT to denote a "simulated refresh rate" for eye-tracking of moving objects. This will not fix stroboscopic effects caused by finite refresh rates & finite frame rates, especially for stationary-eye situations on motion content scrolling past your vision gaze.
