UGREEN HDMI vs DisplayPort vs VGA: Differences, Compatibility & Which Cable Should You Use?

Choosing between HDMI vs DisplayPort vs VGA depends on the devices you want to connect, the display resolution you need and whether your setup requires audio, high refresh rates or multiple monitors. These three display connections are commonly used with laptops, desktop computers, monitors, projectors and audiovisual equipment, but they have important differences.

In this UGREEN display cable guide, we explain how HDMI, DisplayPort and VGA work, compare their compatibility and performance, and help you select the right UGREEN cable, converter or adapter for your home, office, gaming or presentation setup.

HDMI vs DisplayPort vs VGA: Key Differences

HDMI and DisplayPort transmit digital video and can carry audio, while VGA uses an analog video signal and does not carry audio. Their practical performance also differs according to the supported standard and connected hardware.

Important: Maximum resolution and refresh rate are not determined by the cable name alone. They depend on the video source, display, supported interface version, cable capability and any adapter or docking station in between.

1. What Is HDMI and When Should You Use It?

HDMI (High-Definition Multimedia Interface) is a digital connection used to transmit video and audio between compatible devices. It is widely used in home entertainment systems, gaming consoles, laptops, televisions, projectors and computer monitors.

HDMI is often the simplest choice when both devices have compatible HDMI ports.

Common Uses of HDMI Cables

• Connecting a laptop to a monitor or television.
• Connecting gaming consoles to compatible TVs.
• Connecting a computer to a projector.
• Connecting streaming devices to televisions.
• Connecting compatible audiovisual equipment.
• Connecting media players and presentation systems.

HDMI Versions: HDMI 1.4 vs 2.0 vs 2.1

Actual supported modes vary with hardware capabilities, signal format and available bandwidth. HDMI 2.1-labelled devices do not necessarily implement every optional feature.

UGREEN HDMI 2.1 8K Male-to-Male Cable

The UGREEN HDMI 2.1 8K Male-to-Male Cable HD171, 3m is an option for connecting compatible HDMI source devices to monitors, televisions and other displays.

For high-resolution or high-refresh-rate use, verify that the source, display and cable support the intended signal format.

2. What Is DisplayPort and When Is It Better Than HDMI?

DisplayPort (DP) is a digital display interface commonly found on desktop graphics cards, professional monitors, business workstations and selected laptops.

It supports digital video and audio and is widely used in computer environments requiring high resolutions, high refresh rates or advanced monitor configurations.

Why Use DisplayPort?

• Connecting desktop graphics cards to compatible monitors.
• Supporting high-resolution professional displays.
• Using high-refresh-rate gaming monitors.
• Connecting supported multiple-monitor workstations.
• Using compatible adaptive-sync display technologies.
• Supporting DisplayPort MST on compatible hardware.

DisplayPort 1.2 vs 1.4 vs 2.1

Different DisplayPort versions offer different bandwidth capabilities.

• DisplayPort 1.2: Commonly supports 4K at 60Hz on suitable hardware.
• DisplayPort 1.4: Supports higher-bandwidth display modes and Display Stream Compression (DSC) on compatible devices.
• DisplayPort 2.1: Supports newer high-bandwidth configurations for demanding resolutions and refresh rates, depending on the supported link rate.

DisplayPort version alone does not guarantee a particular resolution. Check the capabilities of the graphics card, monitor and cable.

Can DisplayPort Connect Multiple Monitors?

Yes. DisplayPort supports Multi-Stream Transport (MST), which allows compatible systems to transmit multiple display streams through a supported connection.

Some monitors also support DisplayPort daisy-chaining, although this requires appropriate monitor outputs and compatible hardware.

For practical connection instructions, read our guide to connecting two monitors to a laptop using a UGREEN docking station. It explains laptop compatibility, Windows and Mac display settings, and common dual-monitor troubleshooting steps.

3. What Is VGA and Is It Still Useful?

VGA (Video Graphics Array) is a legacy analog video connection commonly recognised by its 15-pin connector.

VGA is still useful when connecting older office monitors, projectors, industrial displays and legacy computers.

Unlike HDMI and DisplayPort, VGA transmits analog video only and does not carry audio.

Common VGA Applications

• Older office desktop monitors.
• Legacy classroom and meeting-room projectors.
• Older desktop computers.
• Industrial and specialised legacy equipment.
• Existing audiovisual installations using VGA.

Does VGA Support Full HD?

VGA can carry Full HD and some higher-resolution analog video signals when the source, display and cable support them.

However, VGA signal quality can be affected by cable length, shielding, electrical interference and the quality of the connected hardware.

For modern high-resolution digital displays, HDMI or DisplayPort is generally preferable where available.

UGREEN VGA Male-to-Male Cable

For equipment with compatible VGA connections, the UGREEN VGA Male-to-Male Cable, 2m provides an analog video connection between supported devices.

Remember that a VGA cable does not carry audio. If sound is required, use a separate supported audio connection.

HDMI vs DisplayPort for Gaming: Which Is Better?

Both HDMI and DisplayPort can support high-quality gaming displays. The best connection depends on your graphics card, monitor, console and desired resolution or refresh rate.

Recommendation: Compare the exact HDMI and DisplayPort specifications of your monitor and graphics card. The better connection is the one that supports your required resolution, refresh rate, colour format and display features.

HDMI vs VGA: Which Is Better for Office Monitors and Projectors?

For modern office monitors and projectors, HDMI is generally preferable because it provides digital video and can also transmit audio.

VGA remains useful when existing equipment lacks HDMI or another compatible digital connection.

If your laptop has HDMI but the projector only accepts VGA, a compatible active converter may be required.

UGREEN HDMI to VGA Converter

The UGREEN HDMI to VGA Converter MM103 with Audio is designed for connecting a compatible HDMI source to a VGA display.

The conversion is directional: an HDMI-to-VGA converter should not be assumed to work from a VGA source to an HDMI display.

Because VGA does not carry audio, a converter with a separate audio output may provide sound through an additional compatible audio connection.

DisplayPort to HDMI: Can You Connect Different Video Ports?

Yes. A suitable DisplayPort-to-HDMI adapter can connect compatible equipment with different video connectors.

However, not every adapter supports both signal directions, and some connections require active conversion.

UGREEN DisplayPort to HDMI Female Converter

The UGREEN DisplayPort to HDMI Female Converter 1080p is intended for connecting a compatible DisplayPort source to an HDMI display.

Its listed 1080p specification should be considered when selecting an adapter for Full HD monitors. Do not assume it supports 4K or reverse HDMI-to-DisplayPort conversion.

HDMI Splitter vs HDMI Adapter: What Is the Difference?

HDMI accessories perform different functions, and choosing the wrong type can prevent a display setup from working as intended.

UGREEN HDMI 1 In 4 Out Splitter

An HDMI splitter distributes a compatible HDMI input signal to multiple HDMI outputs.

For example, the UGREEN HDMI 1 In 4 Out Splitter 40202 is intended for distributing one source to multiple compatible displays.

Important: A conventional HDMI splitter generally duplicates the same video source. It does not create four independent extended computer desktops.

UGREEN HDMI Female-to-Female Adapter

An HDMI coupler connects two compatible HDMI cables together.

The UGREEN HDMI Female-to-Female Adapter is useful where two HDMI cable ends need to be joined.

Keep in mind that extending a cable connection can affect signal reliability, particularly at higher bandwidths or over longer cable runs.

Can You Connect Two Monitors Using HDMI or DisplayPort?

Yes, provided your laptop or computer supports the required number of external displays and has suitable video outputs or a compatible docking station.

For example, a supported docking station may offer HDMI and DisplayPort outputs for connecting two monitors. The available display modes depend on the dock, host computer and operating system.

DisplayPort MST can also support multiple monitors on compatible equipment, while conventional HDMI splitters generally mirror the same image rather than creating independent desktops.
