How we check

Two levels of product information

The broad name index helps you find older and less common products. Its GPU records come from DBGPU and its display records from Linux Hardware Project EDID. EDID entries can be monitors, televisions or panels; a vendor code may differ from the retail brand. These records alone never produce a green compatibility result.

For automatic comparisons, we research exact board connectors and native monitor modes in manufacturer specifications and manuals. Some graphics-card output rates come from the GPU maker’s architecture documentation and are matched to separately checked board sockets. A generic “RTX 4060” name is not silently substituted for a particular partner card.

How a cable is compared

We look for a matching physical connector, a manufacturer-listed native mode and enough checked capacity at both ends and in the cable. Exact pixel clocks are used where available. Where an older input cannot use compression, covering that input’s entire specified capacity can establish support without inventing a clock.

A conservative capacity bound can confirm a lower setting without proving that higher settings are impossible. Missing clocks on a compression-capable input remain unconfirmed. We show yellow only for a supported lower mode with a demonstrated input, cable or output limit.

Scope and updates

The current comparison covers one monitor connected directly to a desktop card, using RGB 8-bit SDR. HDR, variable refresh, DSC, adapters, docks, multi-monitor sharing and game FPS need separate evidence. Fullscreen tests do not measure response time or colour accuracy. Source links appear with the result so you can inspect the basis yourself.

Index imports are normalized and deduplicated. Product facts are reviewed separately; a new name does not automatically become a checked mode. If a manual revision, SKU or regional configuration differs, use the specifications for the product you actually own.
