Frequently Asked Questions
How do I check my monitor refresh rate? +
Run the refresh rate test in the browser tab on the monitor you want to inspect. Keep the tab focused and compare the measured frame delivery against your operating system display setting.
Why does my 144 Hz monitor show 60 Hz? +
Common causes are the OS set to 60 Hz, the wrong cable or port, mirrored displays, battery saving mode, browser throttling, or hardware acceleration being disabled.
Can a browser test prove exact gaming refresh rate? +
It can confirm practical frame delivery in the browser, but games can behave differently. Use it as a quick settings and cable check, then verify in your GPU panel or game settings.
