DisplayPort cables connect a PC, laptop or graphics card to a monitor, and suit gamers, office users and anyone building a multi-screen desk. The category covers full-size DisplayPort leads, Mini DisplayPort versions and DisplayPort to HDMI cables. Listings can change, so check each product page for the exact version and length.
How to choose a DisplayPort cable
DisplayPort version. The version sets the maximum resolution and refresh rate. DisplayPort 1.2 handles 4K at 60 Hz, DisplayPort 1.4 adds 4K at higher refresh rates and 8K with compression, and DisplayPort 2.1 is aimed at the newest high-resolution monitors. Your graphics card and monitor must support the version too, otherwise the cable is not the limit.
Connector type. Check the ports on both devices before buying. Full-size DisplayPort is standard on most graphics cards and monitors, while Mini DisplayPort appears on some older laptops and workstation cards. A cable with the wrong end is the most common reason for a return.
Length. Choose the shortest cable that reaches comfortably. Passive cables lose signal quality over longer runs, and at high resolutions and refresh rates a lead of around 2 metres or less is the safer choice. For longer distances, look for an active cable.
Certification and build. Cables certified by VESA are tested against the version they claim, which matters for 4K 120 Hz and 8K. A locking latch stops the plug working loose, and good shielding helps avoid flicker or signal dropouts.
Cable types and brands
- DisplayPort to DisplayPort: the usual choice for connecting a graphics card to a monitor, and the cable that supports adaptive sync features such as FreeSync and G-Sync on compatible screens.
- Mini DisplayPort to DisplayPort: links a laptop or workstation with a Mini DisplayPort output to a full-size monitor input.
- DisplayPort to HDMI: lets a DisplayPort output drive a monitor or TV that only has HDMI, and works in that direction only.
No manufacturer listing is available for this category at the moment, so check the brand and stated DisplayPort version on each product page before ordering.
DisplayPort cable FAQ
Which DisplayPort version do I need for 144 Hz?
DisplayPort 1.2 is enough for 1080p and 1440p at 144 Hz. For 4K at 120 Hz or 144 Hz, you need DisplayPort 1.4 or newer. Your monitor and graphics card must support the same version.
Is DisplayPort better than HDMI for a monitor?
On a PC, DisplayPort is often the better fit because it supports high refresh rates, adaptive sync and daisy-chaining several monitors on compatible screens. HDMI 2.1 is also capable, so the answer depends on which ports your devices have. Televisions and consoles usually favour HDMI.
How long can a DisplayPort cable be?
A passive DisplayPort cable works reliably up to about 2 to 3 metres at high resolutions, and longer runs may cause signal dropouts. At lower resolutions, longer cables can work. For distances well beyond that, an active cable is the safer option.
Can I use a DisplayPort to HDMI cable the other way round?
No, a DisplayPort to HDMI cable only carries a signal from a DisplayPort source to an HDMI display. Connecting an HDMI source to a DisplayPort monitor needs a different, active converter. Check the direction on the product page before buying.
