Motion Clarity Test

Test monitor motion clarity, ghosting and refresh rate online for free. Compare 60Hz vs 144Hz vs 240Hz smoothness, then tune Overdrive and moving text readability.

Gaming Test

Pro motion clarity for 240Hz+ play

Default speed is 960 px/s with a black high-contrast canvas, tuned for FPS camera pans, 1ms GTG panels, and Overdrive calibration.

Visual: KTC mecha sprite
Focus: high refresh advantage
Target: upgrade from 60Hz to high refresh

Refresh Rate Comparison

Compare a selectable high-refresh row against 60 FPS, 30 FPS, and 15 FPS motion rows at the same speed to see smoothness, stepping, and pursuit tracking differences.

High refresh row

Custom refresh rate FPS FPS

Waiting for demo. The 60 FPS row should look smoother and easier to track, while 30 FPS and 15 FPS rows should step more visibly.

Ghosting & Overdrive Test

Run a sharp moving object across black, gray, and white backgrounds, then classify the trail you see to tune response time and Overdrive.

Background

Speed 800 px/s

Observed trail

Estimated screen refresh rate: detecting. Use the background switch to check black-to-gray and gray-to-white transitions. Bright reverse trails usually mean Overdrive is too high.

Gaming Overdrive Guide

Open the monitor OSD menu and find Overdrive or OD.
Move through Off, Low, Middle, and High while watching the moving edge.
Choose the highest setting with the shortest trail and no bright inverse ghosting.
KTC M27 series baseline: Middle balances speed and overshoot.

Moving Text Test

Find the fastest scrolling text speed you can still read cleanly. This approximates your motion readability threshold.

Font size

Speed 600 px/s

Current text speed: 600 px/s. Raise the speed until the sentence is no longer cleanly readable; that point is your motion readability threshold.

Pair motion clarity testing with grayscale, dead-pixel, and backlight checks before you decide whether the issue is motion tuning, panel uniformity, or the source chain.

Grayscale Gradient

Grayscale Gradient Test

Compare 8-bit vs 10-bit grayscale smoothness, inspect color banding, and check 0%-10% shadow detail online.

Pixel Checker

Dead Pixel Checker

Cycle pure black, white, red, green, and blue screens to inspect dead, stuck, or dim pixels before daily use.

Backlight Bleed Test

Use a fullscreen neutral gray panel to inspect corner glow, edge brightening, and uneven backlight distribution.

What is Motion Blur and Why Does it Matter?

MPRT vs GtG: What's the Difference?

MPRT describes how long a moving image remains visible on screen, while GtG measures pixel transition time between gray levels. Both affect perceived blur.

How Refresh Rate Affects Gaming Performance

Higher refresh rates reduce frame hold time, so target movement and camera pans feel smoother and easier to track beyond the simple feeling of smoothness.
