Response specifications often look contradictory because they measure different events. MPRT versus GtG response time becomes clear once picture persistence and pixel-transition speed are separated.

Quick Answer

MPRT measures picture persistence; GtG measures pixel transitions. A 0.5ms MPRT claim can coexist with slower 1ms to 6ms GtG transitions because these two methods describe different parts of display behaviour.

🕒 What MPRT measures

Moving Picture Response Time estimates how long a moving image remains visible to the eye. Shorter persistence can make a tracking target look clearer. It is often connected to refresh behaviour and may use a test method that differs from a pixel transition chart.

The Legion 27-2c is specified with 0.5ms MPRT and a 280Hz mode. That tells you it is aimed at motion clarity, but it does not state that every shade changes in 0.5ms. Compare high-refresh gaming monitors with the measurement labels in mind.

🔄 What GtG measures

Grey-to-grey timing concerns how quickly a pixel moves between two shades. Slow dark transitions can create a trailing smear even where a panel has a strong MPRT figure. Overdrive can improve some transitions, but too much can introduce inverse ghosting.

🧪 Use visible tests to choose

Watch a familiar high-contrast motion scene at the refresh rate you will actually use. Look for dark trails, bright halos and uneven movement. The gaming monitor category is a useful shopping starting point, but the useful setting is the one that looks clean in your game rather than the smallest number on a box.

Test the two artefacts separately

Use a dark object moving over a mid-grey background to look for a slow dark trail, then use a high-contrast edge to look for a bright halo. The first can point to slower dark transitions; the second often appears when overdrive pushes a pixel beyond its intended value. A single response number cannot predict both effects because the test methods describe different behaviour.

At 280Hz, a new refresh begins roughly every 3.57ms, so timing is tight, but MPRT and GtG should not be treated as interchangeable labels. The Legion 27-2c lists 0.5ms MPRT, which is a motion-persistence measure. Choose a response setting by what you can see in your own games: retain clear moving edges without replacing one trail with a brighter, more distracting one. The gaming monitor category helps compare panels after that test rather than before it.

Match the test to the game you play

Competitive shooters make brief, high-contrast targets and rapid turns the useful test. A dark adventure game instead reveals whether shadow detail and slow near-black changes are distracting. Use one representative scene for each type of game rather than treating a synthetic UFO animation as the final answer. Synthetic tests are excellent for revealing an artefact, but a setting that looks perfect there can feel too aggressive in an actual match.

Keep the same viewing distance and room light while comparing settings. Bright daylight can hide dark trails; a very dim room can make small colour changes look larger than they do in normal use. It also helps to leave a setting in place for a full round before judging it. The eye adapts quickly, so switching back and forth every few seconds can turn an ordinary difference into an apparent problem.

This process gives the advertised measurements their proper role. MPRT explains why a motion-focused mode can look crisp, and GtG explains why particular shade changes can still misbehave. Neither number chooses the response setting for you. The successful result is the one with readable movement, controlled contrast and no obvious bright overshoot in the content that occupies most of your time.

Frequently Asked Questions

Is MPRT more important than GtG

Neither replaces the other. MPRT helps describe persistence, while GtG helps explain pixel-transition artefacts.

Can overdrive improve GtG

It can improve some transitions. Test it carefully because extreme overdrive can create bright overshoot.

Does higher refresh remove slow transitions

No. It shortens refresh intervals but cannot make every pixel transition instantly faster.
