Questions people ask
How does the diagnosis work?
Your description, panel type and any readings you include are sent to an AI model with instructions limited to display problems. It suggests the likely cause, which ScreenCheck Pro test confirms it, and what to try. It can be wrong; confirm with the suggested test before returning a monitor.
