How long is one frame at 360 Hz?

2.78 ms: 1000 ms divided by 360. Each frame stays on screen that long before the next replaces it.

How much motion blur does 360 Hz give?

On an unstrobed panel, an edge moving at 1920 pixels a second smears about 5.3 px: 2.78 ms times 1920 px/s divided by 1000. At 960 pixels a second it is 2.7 px. Pixel response and strobing change what you see, and a browser cannot measure them.

How do I check that my screen is really running at 360 Hz?

Run the refresh rate test. It times frames for ten seconds in the browser and reports the rate the screen is running at and the panel rate it matches.

Does Windows Dynamic Refresh Rate work at 360 Hz?

Microsoft says DRR requires a display that supports VRR and a refresh rate of at least 120 Hz, and that Windows 10 does not support it.

Refresh rates/360 Hz

360 Hz Each frame up for 2.78 ms.

A frame is up for under three milliseconds, so how fast the pixels themselves change becomes a large share of what the eye sees, and no browser test can measure that.

Frame interval and motion blur

Frame interval: 2.78 ms; 1000 / 360
Pattern speed: 1,920 px/s; 5.33 px a frame
Blur of a moving edge: 5.3 px; 2.78 ms x 1,920 px/s / 1000

The speed is the one the motion tests use at this rate: 960 pixels a second below 240 Hz and 1920 from 240 Hz, so each frame moves at least four pixels. The blur is what an unstrobed panel shows when your eye follows the edge. Pixel response time, overdrive and backlight strobing change what you see, and no browser test can measure them. The motion blur explainer has every rate at one speed.

The refresh rate test times frames for ten seconds and reports the rate your screen is running at. A reading of 360 Hz means the screen is running at 360 Hz now. A lower reading on a monitor sold at 360 Hz usually means a setting, a cable, battery power or a second monitor is holding it back: see is my monitor really 144 Hz and laptop stuck at 60 Hz on battery.

The frame pacing test shows whether frames arrive evenly at that rate, and the monitor motion test moves a pattern at 1,920 px/s so you can see the blur for yourself.

What applies at 360 Hz

VESA's AdaptiveSync Display logo carries the maximum frame rate a monitor reaches in Adaptive-Sync operation. VESA: "Values in the logo will include 144, 165, 240, 360, etc."

Windows 11 can lower the rate when you are not gaming or scrolling, called Dynamic Refresh Rate. Microsoft: "DRR requires that a display supports VRR and a refresh rate of at least 120 Hz", and "Windows 10 does not support Dynamic Refresh Rate (DRR)."

On Windows 11 the rate is chosen in Settings > System > Display > Advanced display settings, next to Choose a refresh rate.

What a browser cannot tell you

Response time, input lag, the panel type and the range of a variable refresh rate are not visible to a web page. The refresh rate test measures the fixed rate the browser sees. The variable refresh rate explainer covers what that leaves out.
