Use & limitations

Before connecting or buying

Confirm the exact model and revision on the product label or purchase record. A nearby name, laptop GPU or different memory edition may have different connectors. Review the source linked in the result and the cable’s actual certification marking.

Firmware, drivers, operating-system settings, cable condition and monitor-menu settings can affect actual use. A supported connection does not guarantee the same game FPS. If the result is unknown, do not treat it as proof that a purchase will work or that the hardware is incompatible.

Screen tests and manual values

The visual tests show patterns for you to inspect. They do not repair pixels or diagnose a fault automatically. Stop a pattern if it is uncomfortable to view. Manual mode compares the numbers you enter; a green manual result verifies the arithmetic conditions, not the accuracy of those numbers.

Corrections and reuse

We aim to make sources and limitations clear. Product information can change or be incomplete. Corrections should identify the exact product and a manufacturer source. External specifications and dataset licences remain governed by their respective owners; see the data links on the home page.
