MPRT, GtG and overdrive describe connected but different parts of monitor motion. MPRT tracks visible persistence, GtG measures pixel transitions, and overdrive pushes those transitions faster while risking halos when the voltage is too aggressive.
Monitor response is not a single number because visible motion is made from several behaviours. Pixel transitions, frame persistence and the voltage boost used by overdrive can each improve one artefact while introducing another.
MPRT, GtG and overdrive describe connected but different parts of monitor motion. MPRT tracks visible persistence, GtG measures pixel transitions, and overdrive pushes those transitions faster while risking halos when the voltage is too aggressive. The Lenovo Legion 27Q-10 lists 0.5ms MPRT on a 240Hz IPS panel, so use motion tests rather than comparing one label with another measurement method.
When an object moves across a sample-and-hold screen, each frame remains visible until the next refresh. If your eyes track that object, the persistence can make the moving edge look soft. Higher refresh shortens the time each frame is held. At 240Hz, a new refresh is possible every 4.17ms, compared with 8.33ms at 120Hz.
That is only one contributor. A pixel also has to move from one shade to another. If it arrives slowly, an object may leave a dark or coloured trail. Finally, the display's backlight behaviour can change how long the moving image remains visibly persistent. A useful diagnosis identifies which of these is visible before changing a control.
Moving picture response time, or MPRT, describes visible persistence in motion. It can involve a timed or strobing backlight mode, so its value is influenced by more than the liquid-crystal pixel transition. The Legion's 0.5ms MPRT rating belongs to that type of measurement.
Grey-to-grey, or GtG, describes how a pixel changes from one grey shade to another. Different shade pairs can move at different speeds, so one advertised result may represent a selected fast transition rather than every transition a panel performs. MPRT and GtG both relate to motion clarity, but they are not interchangeable stopwatches. The obvious answer, choosing the lower number without reading the label, is therefore wrong.
Overdrive applies extra voltage to encourage pixels to reach the next shade faster. A moderate setting can reduce ordinary ghosting. An aggressive setting can push past the intended shade, creating a pale edge, dark rim or inverse shadow behind a moving object. That overshoot can be more distracting than the original trailing.
Do not set overdrive from a static desktop image. Use a high-contrast edge in a familiar game, pan at a repeatable pace and compare the normal setting with one step above and below. Repeat at a high and lower frame rate. A mode that looks good near the monitor maximum can show obvious halos when the game falls well below it.
Tearing is not a response-time artefact. It occurs when a new GPU frame appears during the display's scan of the previous one, often as a horizontal discontinuity. Adaptive sync addresses that timing relationship on a suitable system. For that task, the Legion offers VESA Adaptive Sync alongside AMD FreeSync Premium and NVIDIA G-SYNC Compatible, helping a compatible display follow uneven frame delivery.
Configure resolution, refresh and sync before deciding whether response is the problem. Use a direct connection, select 2560x1440 and the intended refresh, then enable sync in the display and driver menus. A poor connection or a disabled sync option can make motion look wrong for reasons overdrive cannot solve.
Choose one scene with white signage against a dark wall, another with a bright object crossing a sky, and a third with ordinary gameplay. Record the refresh mode, fps range, sync status and overdrive level. Look for dark smearing, inverse halos and whole-frame tears separately. This record prevents a setting that helped one game from becoming a misleading default for everything else.
Use a persistence-reduction mode only after the basic configuration is stable. It may increase perceived clarity in a high-fps title, but check brightness and comfort over a full session. A setting that is technically sharper but too dim or tiring is not the best setting for daily use.
The Legion's QHD 240Hz IPS combination gives a high-refresh platform for motion tuning. Its 0.5ms MPRT figure is one useful point in that platform. The product also has inputs and stand adjustment that help establish the correct connection and viewing position. Gaming monitors should be compared on their measured and usable motion behaviour rather than an isolated headline.
Response testing is easiest when the display is at a comfortable height, the cable connection is stable and the same game scene can be revisited. A monitor arm or cable choice does not change pixel speed, but it can remove the accidental movement and connection uncertainty that make an image comparison hard. Review monitor accessories only after the panel settings themselves are understood.
Record the fps range alongside every response observation. A setting that looks controlled near 220fps may reveal overshoot when a demanding scene falls to 100fps, because the monitor has more time between updates. This is why an ordinary match is a stronger test than a synthetic clip. The aim is not to win an isolated motion test; it is to retain clear edges through the performance range that the PC produces in real use.
One final check is comfort. A persistence-reduction setting may make test motion look sharper yet reduce brightness or introduce a feeling of flicker for some viewers. Play a complete session before treating the setting as a permanent improvement.
Write down the selected mode once the test is complete. That small record turns a successful comparison into a configuration you can restore after later experiments.
No. MPRT describes visible moving-image persistence, while GtG describes a pixel change between selected grey shades.
No. It can introduce overshoot halos. Use the lowest setting that clears distracting trailing in your normal fps range.
It helps timing between GPU frames and refresh. Ghosting and overshoot are primarily pixel-response and overdrive issues.
Pixel behaviour and overdrive artefacts can become more or less visible as refresh and frame delivery change.
Ready to tune motion without treating every artefact as the same problem? Test persistence, pixel response and frame timing separately, then keep the setting that remains clean in play.
