the display appears to skip frames at higher refresh rates
If the live test passes, the investigation can usually move away from total hardware failure and toward the affected app, permissions, routing or configuration.
Try the simple causes first
- 1
Run the relevant DeviceOK display test in full screen and separate what is visually observed from what the browser can measure.
- 2
Confirm the operating system is using the display's native resolution and intended refresh rate.
- 3
Reconnect the display cable and verify the correct input/port.
Work through the problem in order
- 1
Run the relevant DeviceOK display test in full screen and separate what is visually observed from what the browser can measure.
- 2
Confirm the operating system is using the display's native resolution and intended refresh rate.
- 3
Reconnect the display cable and verify the correct input/port.
- 4
Compare another cable, port, or device if practical.
- 5
Reset unusual monitor picture-processing settings before deeper troubleshooting.
- 6
For persistent physical panel defects, use the manufacturer's warranty/support criteria rather than relying only on a browser test.
If the display passes the DeviceOK test, prioritize the affected application, permissions, routing, or configuration before assuming the hardware is dead.
If the display also fails in DeviceOK and another trusted app, broaden the diagnosis to connection, OS settings, drivers/firmware, and then possible hardware failure.
