What Is My Refresh Rate? 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 …

This is a popular TestUFO demo seen at conventions and trade shows. As seen at CES and DisplayWeek! Large frame rate differences (4x+) are more human visible with faster pixel …

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.

If camera exposure can't be raised, decrease camera ISO and/or reduce monitor brightness, to make camera do longer exposures. If you see only 1 or 2 white squares in your photo, try again.

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 variable refresh rate technologies including G-SYNC, FreeSync, VESA AdaptiveSync, HDMI 2.1 VRR, and others. Variable refresh rates (VRR) eliminate stutters of …

This emulates a G-SYNC variable refresh rate display via software interpolation. Also, see TestUFO G-SYNC Demo. These animations are accurate only in a stutter-free web browser. …

Hardware-based backlight strobing, often found in gaming monitors, such as ULMB, DyAc, ELMB, PureXP, etc. Hardware-based or software-based black frame insertion, including this demo.

This test simulates the G-SYNC variable refresh rate (VRR) technology. G-SYNC eliminate stutters by varying the refresh rate to exactly match a fluctuating frame rate.
