what monitor ports do i need

Today’s computer monitors offer various port options, each serving different functions and use cases. When investing in a new display, understanding which ports are included—and which ones you truly need—is essential for making an informed decision.

Whether you’re connecting a legacy device or seeking the latest high-speed connections, we’ll help you navigate the world of monitor ports. Read on to learn about the most common types, their specific uses, and how to choose the right ones for your setup.

Most Common Monitor Port Types

HDMI, DisplayPort, and USB-C™ are the most prevalent ports found on modern displays. While legacy options like VGA and DVI are still available for older devices, most users will primarily encounter these newer standards.

Selecting the appropriate port type is crucial because most monitors don’t include all connection options. Let’s examine each port type’s benefits and use cases to help you make an informed decision.

1. HDMI

HDMI (High-Definition Multimedia Interface) ports have become the industry standard. Major film studios, technology manufacturers, and gaming companies widely adopt this interface, making it the most versatile option for most users.

There are four active HDMI cable types compatible with monitor HDMI ports:

  • HDMI Standard: Supports up to 1080p resolution

  • HDMI High Speed: Enables 4K resolution

  • HDMI Premium High Speed: Specifically for HDR-enabled devices

  • HDMI Ultra High Speed: Supports HDMI 2.1 features, including 8K video and 48 GB/s bandwidth

2. DVI

While less common today, DVI (Digital Visual Interface) ports still appear on many displays, often alongside HDMI and VGA ports. DVI offers specific advantages, particularly for gaming applications.

A DVI port can deliver higher frame rates than HDMI on 1080p monitors, thanks to its direct digital signal transmission. This can result in:

  • Clearer picture quality

  • Enhanced image sharpness

  • Better detail reproduction

  • Superior performance for high-refresh-rate gaming

When choosing a DVI cable, opt for a double-link version, which supports up to 2560 x 1600 resolution, compared to single-link cables limited to 1920 x 1200.

3. DisplayPort

DisplayPort (DP) typically appears on premium monitors, particularly those designed for gaming and professional visual work. Current DisplayPort versions include:

  • DisplayPort 1.2: Supports 4K video at 60 Hz

  • DisplayPort 1.3: Enables 8K video at 30 Hz

  • DisplayPort 1.4: Delivers 8K video at 60 Hz with HDR support

A notable DisplayPort advantage is its ability to daisy-chain multiple monitors using a single cable, reducing cable clutter in multi-display setups.

4. VGA

VGA (Video Graphics Array) ports, whilst largely phased out, remain relevant for legacy device compatibility. These 15-pin connectors are particularly useful for:

  • Connecting older PCs to newer displays

  • Supporting legacy presentation equipment

  • Accommodating certain vintage gaming consoles

  • Educational and business environments using older projection systems

5. USB-C

USB-C ports represent the latest evolution in display connectivity, offering remarkable versatility. Benefits include:

  • Reversible connector design

  • Combined video, audio, data, and power delivery

  • Broad device compatibility

  • Simplified laptop-to-monitor connections

  • Future-proof connectivity standard

Maximising Connectivity Options

When selecting a monitor, consider future-proofing your setup by choosing a display with multiple port types. This ensures compatibility with various devices and allows for setup flexibility as your needs evolve.

Modern monitors often include several port types, helping you avoid compatibility issues whilst providing the versatility to connect multiple devices. Consider your specific use cases, current equipment, and potential future needs when evaluating port options.

Remember that adapters and converters are available if you need to bridge between different port types, though native connections typically provide the best performance and reliability.
