A single lead from your laptop’s USB-C port to a DisplayPort monitor. No dongle, no adapter hanging off the side of the machine — one cable, one plug at each end.
Not every USB-C port does. The connector is the same shape whether the port carries video or not, so there is no way to tell by looking. The feature is called DisplayPort Alt Mode, and a port that lacks it will charge and move files down this cable but will never light up a monitor.
Where to look: the manufacturer’s spec sheet, or a small DP or display icon printed beside the port. Thunderbolt 3 and Thunderbolt 4 ports always have it, which is why this usb c to displayport cable works on every modern MacBook.
If you are not sure, tell us the make and model and we will check before you order. It takes us a minute and it is the difference between a cable that works and one that goes back.
This is where most listings stop being honest, so here are both numbers.
The realistic figure is 4K at 60Hz. That is what a USB-C port delivers when it is running video on two of its four high-speed lanes and keeping the other two for USB data — which is how most laptops and every docking station behave.
The maximum is 8K at 60Hz, and reaching it needs three things at once: the laptop must give all four lanes to DisplayPort, which drops its USB data to the slow 480Mbps rate; and both the laptop and the monitor must support DSC, the compression scheme DisplayPort 1.4 uses to fit 8K into its bandwidth. Without DSC the ceiling is 8K at 30Hz, which is not a usable desktop refresh rate.
The cable is not the limit in any of those cases. It is built to DP 1.4 and the marking is printed on the connector housing — the limit is the port at one end and the panel at the other.
For gaming, the useful number is different again. DP 1.4 has ample bandwidth for 1440p at 144Hz or 4K at 120Hz, which is what most people buying a usb c to displayport cable for a gaming monitor actually want.
A laptop on a desk. Lid open or closed, one cable to the monitor, and the DisplayPort end stays plugged into the screen.
A MacBook or a Thunderbolt laptop, where the only video output is USB-C and the monitor only has DisplayPort. This is the gap the cable exists to fill, and because every Thunderbolt port carries DisplayPort Alt Mode, this doubles as a thunderbolt to displayport cable without needing a separate part.
A gaming monitor with a high refresh rate, where DisplayPort is usually the better input to use.
Gold-plated contacts at both ends and aluminium connector housings, on a plain black jacket. The DisplayPort end is a full-size plug — not Mini DisplayPort, which is a different connector and a different cable.
Three lengths: 1m, 2m and 3m. Pick the run you need rather than coiling the slack behind the desk.
This lead runs from a USB-C source to a DisplayPort display. It does not work backwards — a DisplayPort output cannot drive a USB-C screen through it, because the conversion happens inside the laptop’s port rather than inside the cable. That is true of every passive cable of this type, not just this one.
Stocked in Melbourne, not drop-shipped with a three-week wait. Order before 10am and it ships the same day via Australia Post with tracking and insurance, backed by our 90-day warranty.
And by a team who will check your laptop’s port before you order rather than after. DisplayPort Alt Mode is the single thing that decides whether this cable works — it takes us one question and it saves you sending something back.
Tell us your laptop model, then order today.
Works with any device whose USB-C port supports DisplayPort Alt Mode, driving any monitor, TV or projector with a full-size DisplayPort input.
Ports that always have it:
Ports that often do not:
Many budget and mid-range laptops fit a USB-C port for charging and data only, and a phone or tablet is a coin toss — some Samsung Galaxy and recent Android flagships output video, most do not, and no iPhone does.
⚠️ The connector is the same shape either way, so you cannot tell by looking. Check the manufacturer’s spec sheet for “DisplayPort Alt Mode”, or look for a small DP or display symbol printed beside the port — or tell us the make and model and we will check it for you before you order.
A different cable is needed for:
A monitor with a Mini DisplayPort input rather than a full-size one, which is a physically smaller connector, and any monitor whose only inputs are HDMI or VGA — we stock leads for both, so tell us what is on the back of your screen and we will match it.
⚠️ One direction only. This lead runs from a USB-C source to a DisplayPort display. It will not drive a USB-C monitor from a DisplayPort output, because the conversion happens inside the host’s port rather than inside the cable — true of every passive cable of this type.
No power or data passes to the monitor beyond the video signal, and the cable does not charge the laptop.
