    About the 144hz test

    Updated

    Buying a 144Hz monitor doesn't mean it runs at 144Hz. Many ship set to 60Hz, and the wrong cable or port can cap them there. This test measures the rate your screen is actually refreshing at by timing every frame the browser draws, and shows the nearest standard rate. If it reads 60, the steps below and our 144Hz guide walk you through the usual fixes.

    How to use it

    1. Close other tabs and apps and keep this tab in front.
    2. Wait about five seconds for the reading to settle.
    3. If it shows 60 Hz, set the refresh rate in your display settings and check your cable.
    4. Measure again to confirm the change took effect.

    Frequently asked questions

    Why does my 144Hz monitor show 60Hz?

    The most common causes are the Windows or macOS refresh rate setting, an older HDMI cable or port, or a desktop monitor plugged into the motherboard instead of the graphics card.

    Is DisplayPort or HDMI better for 144Hz?

    DisplayPort works on almost every high refresh monitor. HDMI works too, but older HDMI ports and cables often can't carry 144Hz at higher resolutions, so try DisplayPort if you're stuck at 60.

    Does this test 165Hz and 240Hz monitors?

    Yes. It measures whatever rate your screen runs at and shows the nearest standard rate, including 120, 165, 240 and 360 Hz.
