Cables for PC, Display & Network 🔌
HDMI, DisplayPort, USB & Network Cables (51)
How to Choose the Right Cable
Cables aren't all the same, but you also don't need the most expensive one. What matters is the right standard for what you're connecting and a length that's long enough without being wasteful. Spend on the standard, not on marketing. The guide below covers the choices that actually change performance.
Both carry 4K and high refresh rates, so often it comes down to the ports on your devices. DisplayPort is common on PC graphics cards and gaming monitors and handles very high refresh rates well. HDMI 2.1 is standard on TVs and consoles and supports 4K at 120Hz. Use whichever matches both ends, and make sure the cable is rated for your resolution and refresh rate.
HDMI 2.1 is the one to look for if you want 4K at 120Hz or features like variable refresh rate (VRR) for tear-free gaming. Older HDMI 2.0 cables top out at 4K 60Hz. A cable labelled "Ultra High Speed" meets the 2.1 bandwidth requirement — that label matters more than the price.
Cat 6 handles gigabit speeds and is the sensible default for home gaming and networking. Cat 6a adds headroom and better shielding for longer runs. Cat 8 exists for data-centre use but is overkill for a home line. For gaming, the bigger win is simply going wired instead of Wi-Fi for lower, more consistent latency.
Within normal lengths, a properly rated cable performs to spec. Very long runs can lose signal — especially for high-bandwidth video — so buy a cable just long enough to reach without excess slack. For long video runs over several metres, look for cables explicitly rated for that distance and resolution.
USB-C is the modern reversible connector found on newer peripherals, phones and laptops; USB-A is the older rectangular plug still used widely. Thunderbolt uses the USB-C shape but adds much higher bandwidth for displays and fast storage. Check the cable's speed rating and whether it supports power delivery if you plan to charge through it.
