Monitor pixel tester
For more accurate measurements, do both black/white and inverse white/black tests, and average the results. This motion test is incompatible with frame-interpolating displays. However, this motion test will not work with frame-interpolation. Note: This motion test is compatible with impulse-driving. This test allows you to measure the actual correct representative number as seen by the human eye, which may sometimes be lower than advertised numbers. It represents the same perceived display motion blur as an ideal sample-and-hold display refreshing at a Hz matching the MCR value. Techniques such as frame-interpolation and impulse-driving (scanning backlights, strobing) frequently combine toĬreate higher Motion Clarity Ratios (MCR). To represent an equivalence to a refresh rate. Similiar terms are sometimes used by TV manufacturers ("Clear Motion Ratio", "Motion Clarity Index", etc.) Motion Clarity Ratio (MCR) is equal to 1000 divided by MPRT. For more information about display persistence, see Blur Busters Law. However, the more scientific term is Moving Picture Response Time (MPRT) found in science papers on Google Scholar. MPRT is also known in some industry circles as "persistence". square-wave strobe backlight), MPRT is exactly equal to strobe flash length. For the scientifically ideal instant-response sample-and-hold display, MPRT is exactly equal to the time period of one refresh cycle.įor the scientifically ideal impulse-driven display (e.g. MPRT is a more accurate representation of visible motion blur blur (see Eye Tracking Motion Blur Animation demo). MPRT can still create a lot of display motion blur even if pixel response (GtG) is instant. GtG is the pixel transition time, while MPRT is pixel visibility time. Moving Picture Response Time (MPRT) is display persistence. A different animation is TestUFO: GtG versus MPRT.
