0.5ms MPRT vs 1ms to 4ms GtG Response

A response-time label only makes sense when you know what it measures. MPRT describes how long moving imagery remains visibly persistent, while grey-to-grey timing tracks a pixel changing between shades.

Quick Answer

0.5ms MPRT cannot be compared directly with 1ms to 4ms GtG. MPRT describes visible persistence of a moving image, often with backlight timing involved, while GtG measures pixel transitions that vary by shade and overdrive level. The Lenovo Legion 27Q-10 lists a 0.5ms MPRT rating, which should be read as one part of motion behaviour rather than a universal pixel-time claim.

🔍 What MPRT describes

Sample-and-hold displays keep a frame visible until the next refresh. When your eyes follow a moving object, that persistence can make the object appear softer. MPRT measures the visible persistence of moving imagery and can involve a strobing or timed-backlight mode that reduces the period each frame remains visible.

That can improve perceived clarity in a suitable high-fps test, but it may involve brightness, flicker or synchronisation trade-offs. MPRT therefore is not a direct stopwatch for every pixel transition.

⚙️ What GtG describes

Grey-to-grey timing measures a pixel changing from one grey shade to another under chosen conditions. Panels do not move through every shade at one identical speed. A quoted 1ms result may describe a fast selected transition, while a slower transition can occur elsewhere on the same panel.

Overdrive is often used to accelerate pixel changes. Too little can leave trailing; too much can overshoot and create a bright or dark halo. The best setting is the one that looks clean in the fps range you use, not automatically the maximum menu position.

🧪 Test what you can see

Use a game scene with a clear high-contrast edge and pan the camera at a repeatable speed. Look for a dark smear, then look separately for an inverse bright outline. Repeat at a high and a lower frame rate because overdrive behaviour can look different as refresh conditions change.

For setup tools and suitable cables, review monitor accessories. The accessory itself does not determine response, but a correct connection and stable configuration make the test meaningful.

Use gaming monitor comparisons to keep the response-time test connected to the panel and refresh range you are considering. A useful extra check is to test a light object over a dark background and a dark object over a light one; different pixel transitions can expose different trails. Keep the same game, camera movement and brightness while comparing settings so the conclusion comes from the response behaviour rather than a changed scene.

Frequently Asked Questions

Is 0.5ms MPRT faster than 1ms GtG?

They measure different behaviour, so they cannot be ranked directly. Read the method before comparing the number.

Does maximum overdrive always reduce blur?

It may reduce one kind of trailing while adding overshoot halos. Test it with moving content at your normal frame rate.

Does higher refresh help motion clarity?

It can reduce frame persistence by showing new images more often. Pixel behaviour and settings still matter.
