How to Choose Computer Cables
Match the cable standard to what both devices support. A Thunderbolt 4 cable in a USB 3.0 port runs at USB 3.0 speeds, so overspending on cable spec beyond what the ports support adds no benefit. For video output, choose DisplayPort for PC monitors with high refresh rates and HDMI for TVs and consumer displays. Always buy certified cables for HDMI and USB rather than unbranded options; uncertified cables frequently fail to hit rated specs. Length matters for cable management: buy the shortest length that works comfortably to reduce clutter.

Frequently asked questions
What is the difference between USB 3.2 and USB4 cables?+
USB 3.2 Gen 2 cables support up to 10Gbps data transfer, while USB4 cables support up to 40Gbps and are based on the Thunderbolt 4 specification. USB4 cables also support video output and up to 100W power delivery. The physical connector is usually USB-C for both. Not all USB-C cables are USB4 even if they look identical, so check spec labels before purchasing for high-speed use.
Do expensive HDMI cables actually perform better than budget ones?+
For resolutions up to 4K at 60Hz, a quality budget HDMI 2.0 cable performs identically to a premium cable. HDMI is a digital signal, so either it works correctly or it does not. The main reasons to spend more are build quality for frequent plug/unplug cycles, braided shielding for durability, and HDMI 2.1 certification for 4K at 120Hz or 8K output. Avoid buying expensive cables marketed purely on brand for standard use.
