Compare USB-C to HDMI and USB-C to DisplayPort cables for monitors, projectors, and TVs. Learn which video adapter fits your setup and how to avoid compatibility issues.
Quick answer
Choose USB-C to HDMI if you need a universal connection for TVs, projectors, and most monitors. Choose USB-C to DisplayPort if you have a monitor with DisplayPort input and want higher bandwidth for high refresh rates or multi-monitor setups. Both use the same USB-C video output standard, so the real difference is the display port on the other end.
What USB-C video output actually does
USB-C video output uses the Alt Mode standard to send a video signal through the same USB-C port that charges your laptop or transfers data. The USB-C end is identical for both HDMI and DisplayPort cables. The difference is entirely on the display side. If your monitor has HDMI, you need a USB-C to HDMI cable. If it has DisplayPort, you need a USB-C to DisplayPort cable. There is no performance advantage to one over the other at the same resolution and refresh rate.
HDMI vs DisplayPort: key differences for cable buyers
HDMI is the most common video interface on TVs, projectors, and consumer monitors. It supports audio and video in one cable and is backward compatible with older HDMI versions. DisplayPort is more common on PC monitors, especially higher-end models, and supports daisy-chaining multiple monitors. For most home and office setups, HDMI is the safer choice because it works with more devices. If you have a gaming monitor or a multi-monitor workstation, DisplayPort often supports higher refresh rates and resolutions.
Practical advice for choosing your cable
Check the ports on your display before buying. If your monitor has both HDMI and DisplayPort, either cable works, but DisplayPort may offer better performance at 1440p or 4K at high refresh rates. If you are connecting to a TV or projector, HDMI is the only option. For laptops with a single USB-C port, a USB-C to HDMI cable is more versatile because you can also use it with portable monitors and adapters. Do not assume a USB-C to DisplayPort cable will work with a USB-C hub or dock that already has a video port.
Tradeoffs at a glance
- USB-C to HDMI: Works with TVs, projectors, and most monitors. Supports audio and video. Widely compatible. Lower maximum bandwidth than DisplayPort on older HDMI versions. Best for general use and connecting to consumer displays.
- USB-C to DisplayPort: Higher bandwidth for high refresh rates and multi-monitor setups. Common on PC monitors. Does not carry audio over the same cable in all implementations. Best for gaming monitors and workstation setups with DisplayPort inputs.
- Compatibility note: Your device must support USB-C Alt Mode for video output. Not all USB-C ports do. Check your laptop or phone specifications before buying a video cable. Verify Alt Mode support first.
Cables that fit this comparison
- USB-C to 3.5mm AUX Stereo Audio Cable (1m) – Headphone / Car Jack Lead: Connect your USB-C device to any standard 3.5mm AUX input with this 1m stereo audio cable. Ideal for plugging a phone, tablet or laptop into car stereos, speakers, Hi-Fi systems, headphones, soundbars and portable audio gear with a 3.5mm jack. While this is an audio cable, it shows that USB-C can carry audio signals. For video, you need a dedicated USB-C to HDMI or DisplayPort cable that supports Alt Mode video output.
- USB-C 3.1 Angled Male to USB 3.0 Female OTG Extension Cable 5Gbps: USB-C 3.1 Angled Male to USB 3.0 Female OTG Extension Cable – 5Gbps Fast Data Transfer. Designed with an angled USB-C connector for a more comfortable and secure connection. This OTG extension cable demonstrates that USB-C can handle high-speed data. However, it does not support video output. For video, you must use a cable that explicitly supports USB-C Alt Mode for HDMI or DisplayPort.
