Acer Monitor White Screen Problem – Any Solutions?

My Acer monitor randomly turns entirely white—sometimes during boot-up, sometimes after being used. No flicker, just a plain white screen.

Attempts:

Rearranging cables
Inspecting ports (HDMI, DP, etc.)
Testing with another PC (same phenomenon)
Is this a hardware malfunction, or is there an adjustment? Anyone else encountered this?
