Blur Busters UFO Motion Tests with ghosting test, 30fps vs 60fps, 120hz vs 144hz vs 240hz, PWM test, motion blur test, judder test, benchmarks, and more.

This refresh rate test is designed to accurately measure your refresh rate of your display in Hertz (Hz). Wait at least 30 seconds for an accurate measurement. For best results, close other applications & other browser tabs first.

This screen compares frame rates with vertical scrolling. If using a 120Hz monitor, then 120fps is automatically included (30fps vs 60fps vs 120fps) in supported browsers.

This test simulates the FreeSync variable refresh rate (VRR) technology. FreeSync eliminate stutters by varying the refresh rate to exactly match a fluctuating frame rate. This FreeSync emulation uses interpolation techniques to emulate the look the smoothly variable refresh rate on AMD FreeSync displays, with seamless transitions between ...

This new MPRT indicator test is based on works of Josip Reponj & RTINGs, plus enhancements by Blur Busters with an optional multi-row version optimized for end users. As the graphics scrolls sideways, display motion blur from persistence will thicken vertical lines to overlap each other.
