A modern computer, whether it’s a desktop or a laptop, may offer you several port choices when it comes to connecting a display. Depending on your computer, you can have an HDMI port, a regular DisplayPort (DP), or a USB-C port with DP Alt mode, which have replaced the VGA and DVI ports of yesteryears. Each of these ports can help you seamlessly establish a connection to an external display with support for both audio and video signals.
Use USB-C for Multi-Purpose Versatile Setups
USB-C is a pretty versatile interface, and besides data transfer and power delivery, it supports video output when it has a DisplayPort Alt Mode configuration. So, if your desktop or laptop has a built-in USB-C port that supports DP Alt Mode or Thunderbolt, you can use it to send video to a display.
- Single USB-C cable handles video, power, and data simultaneously
- USB Power Delivery (USB PD) enables monitor-to-laptop charging
- Connect peripherals to display USB ports, freeing laptop ports
- Supports daisy-chaining multiple monitors with DP 1.2+ MST
Keep in mind that any storage devices connected to the display may not always get the fastest transfer speeds, as a significant portion of the USB-C connection’s bandwidth will go into transferring the video signal.
Use HDMI for Common TV and Projector Applications
HDMI ports are pretty common on computers and can come in very handy when you’re looking to connect an external display, whether it’s a monitor or a TV. It’s particularly useful for hooking up a TV or projector to your computer for use as a monitor, as you are unlikely to find USB-C with DP Alt mode or DisplayPort on a TV or projector.
- Universal compatibility with TVs, projectors, and consumer displays
- Guaranteed audio and video support—no compatibility uncertainty
- Simple plug-and-play connection with standard HDMI cables
- No additional configuration or driver installation required
Key Comparison Factors
- Single Cable Solution: USB-C (video + power + data) vs HDMI (video only)
- Multi-Monitor: USB-C daisy-chaining vs HDMI direct connections
- Device Compatibility: HDMI (TVs/projectors) vs USB-C (modern monitors)
- Cable Clutter: USB-C reduces cables vs HDMI requires separate power
Choosing between the two depends significantly on your setup, devices, and what you are trying to achieve with your external display configuration.
