Buying Guide

Match connector types and directionality

Confirm the exact ports on your devices and whether an adapter needs to be bi-directional (e.g., HDMI↔DVI) or unidirectional, since some cables and adapters only transmit one way

Check video resolution and refresh support

Choose cables or adapters rated for the resolution and refresh rate you need — e.g., 4K@60Hz support matters for USB-C/mini DisplayPort and DisplayPort-to-HDMI connections

Verify audio passthrough needs

If you need audio over a video link, pick adapters that explicitly support audio pass-through (common with DisplayPort-to-HDMI converters)

Consider cable length and signal integrity

Long runs (like 50ft) require higher-quality construction or active circuitry to preserve signal; shorter integrated adapter cables reduce potential signal loss

Account for legacy and serial connections

For RS-232 or DB9 device connections, use USB-to-serial adapters designed for PC and Mac and check driver compatibility for your OS
