FAQs
How do I test why my 144Hz monitor is not showing 144Hz? +
Select the expected refresh rate in the OS, run the refresh-rate test, and compare a direct certified cable path without adapters or docks.
Can a cable hide 144Hz? +
Yes. Low-bandwidth or uncertified cables can cap available refresh modes, especially through adapters or docks.
Should I buy a new monitor if 144Hz is missing? +
Not before checking OS settings, the display input, direct cable path, and another source. Missing 144Hz is often a cable or setting issue.
