Cable Tools
Interactive tools to help you pick, identify, and validate a video connection: the Cable Selector
Guide finds the right cable or adapter for two devices, the Connector Identifier works out which port
you have, the Video Bandwidth Calculator checks whether a given HDMI or DisplayPort version (and
cable) can carry the resolution and refresh rate you want, and the Max Resolution Finder answers the
reverse question — what is the best mode the hardware you already own can drive.
Cable Selector Guide
Choose your source device and your display, and the guide shows the recommended cable, adapter,
or converter — with caveats like audio not crossing DVI.
Open the Guide
Connector Identifier
Answer a few questions about your connector's shape and pins and we'll identify it —
HDMI, DisplayPort, DVI, USB-C, VGA, and more — with a picture and where to learn more.
Identify a Connector
Max Resolution & Refresh Finder
Pick the port and cable you already have and see the highest resolution and refresh rate they
can carry — plus which end is the bottleneck.
Find My Maximum
Signal Reach Advisor
Say what you are running and how far it has to go, and get the cable type that covers the
distance — passive, active, optical, or an extender.
Check My Run
Device Port Lookup
What ports a PS5, Xbox, Switch, Mac, or graphics card actually has — the versions, the
maximum output, and the cable grade it needs.
Look Up a Device
Cable Label Decoder
Look up what is printed on your cable or its box and find out what that marking actually
guarantees — and which ones are pure marketing.
Decode a Label
Video Bandwidth Calculator
Enter a resolution, refresh rate, and color depth to estimate the required data rate and see
which HDMI/DisplayPort versions and cables support it, with or without DSC.

Step-by-step guides
Also useful: the Connector Compatibility Matrix
for an at-a-glance grid of what connects to what, and the
Troubleshooting guide when a
connection isn't working.
