What Are Display Output Ports?
Display output ports are the connectors that allow you to connect your computer or other devices to a monitor, TV, or projector. They transmit video and sometimes audio signals from the source to the display. There are different types of display output ports, each with its own advantages and disadvantages. Some of the most common ones are:
- HDMI: High-Definition Multimedia Interface. This is the most widely used port for connecting devices to TVs, monitors, and projectors. It can carry both video and audio signals, and supports high resolutions and refresh rates. HDMI is also compatible with other standards, such as DVI and VGA, with adapters. There are different versions of HDMI, such as HDMI 1.4, HDMI 2.0, and HDMI 2.1, which offer different features and capabilities.
- DVI: Digital Visual Interface. This is an older port that is mainly used for connecting computers to monitors. It can only carry video signals, so you need a separate cable for audio. DVI supports high resolutions and refresh rates, but not as high as HDMI or DisplayPort. There are different types of DVI, such as DVI-D, DVI-I, and DVI-A, which differ in the type of signal they can transmit (digital, analog, or both).

- VGA: Video Graphics Array. This is the oldest and most legacy port that is still used for connecting devices to displays. It can only carry analog video signals, so you need a separate cable for audio. VGA supports low resolutions and refresh rates and is prone to interference and signal degradation. VGA is only recommended when there is no other option available.
- DisplayPort: This is a newer port that is designed to replace VGA and DVI. It can carry both video and audio signals, and supports very high resolutions and refresh rates. DisplayPort is also compatible with other standards, such as HDMI and DVI, with adapters. There are different versions of DisplayPort, such as DisplayPort 1.2, DisplayPort 1.4, and DisplayPort 2.0, which offer different features and capabilities.
- USB-C: This is a versatile port that can be used for various purposes, such as data transfer, power delivery, and display output. It can carry both video and audio signals, and supports high resolutions and refresh rates. USB-C is also compatible with other standards, such as HDMI and DisplayPort, with adapters. There are different versions of USB-C, such as USB 3.1, USB 3.2, and USB 4.
- Thunderbolt: This is a specialized port that combines the features of USB-C and DisplayPort. It can carry both video and audio signals and supports very high resolutions and refresh rates. Thunderbolt is also capable of transferring data and power at very high speeds. Thunderbolt is mainly used for connecting devices to external monitors, docks, and storage devices. There are different versions of Thunderbolt, such as Thunderbolt 1, Thunderbolt 2, and Thunderbolt 3.

What is HDMI 2.1?
HDMI 2.1 is the newest version of the High-Definition Multimedia Interface (HDMI), which has been the standard interface for consumer devices for the past two decades. HDMI 2.1 offers significant improvements over its predecessors, such as:
- A higher bandwidth of 48 Gbps, which allows for higher resolutions and refresh rates, such as 4K at 120 Hz and 8K at 60 Hz.
- A new encoding scheme called 16b/18b, which reduces the overhead and increases the efficiency of data transmission.
- Support for dynamic HDR, which adjusts the brightness and contrast of the image according to the content and the display capabilities.

- Support for variable refresh rate (VRR), which synchronizes the display’s refresh rate with the device’s output, reducing screen tearing and stuttering.
- Support for auto low latency mode (ALLM), which automatically switches the display to the lowest latency mode when gaming or using interactive applications.
- Support for enhanced audio return channel (eARC), which enables high-quality audio formats, such as Dolby Atmos and DTS:X, to be transmitted from the display to the audio system.
HDMI 2.1 is compatible with older HDMI devices, but you will need a new HDMI 2.1 cable to enjoy the full benefits of the new features. HDMI 2.1 is mainly used for TVs, game consoles, and streaming devices, but it is also becoming more available for monitors and laptops.

What is DisplayPort 1.4?
DisplayPort 1.4 is one of the latest versions of the DisplayPort protocol, which has been the preferred interface for PC gaming and professional displays. DisplayPort 1.4 offers some advantages over HDMI 2.1, such as:
- A higher data rate of 25.92 Gbps, which allows for higher resolutions and refresh rates, such as 4K at 144 Hz and 8K at 60 Hz, without compression.
- Support for Display Stream Compression (DSC) 1.2a, which enables lossless compression of video and audio signals, increasing the effective bandwidth and reducing the power consumption.
- Support for static HDR, which delivers high dynamic range images with 10-bit or 12-bit color depth and wide color gamut.
- Support for adaptive sync, which is similar to VRR, but also compatible with AMD FreeSync and NVIDIA G-Sync technologies, which optimize the gaming performance and reduce input lag.
- Support for multi-stream transport (MST), which allows for daisy-chaining multiple displays or splitting the signal to multiple displays using a hub or a splitter.
DisplayPort 1.4 is compatible with older DisplayPort devices, but you will need a new DisplayPort 1.4 cable to enjoy the full benefits of the new features. DisplayPort 1.4 is mainly used for monitors, laptops, and desktop PCs, but it is also becoming more available for TVs and game consoles.

FAQs
Chroma subsampling is a technique that reduces the amount of color information in a video signal, allowing for higher resolutions and frame rates with lower bandwidth requirements. However, chroma subsampling can also degrade the image quality, especially for fine details and text.
Not necessarily. You can still enjoy 4K or 8K content with older versions of HDMI or DisplayPort, as long as your display and device support them. However, you may not be able to enjoy the full potential of 4K or 8K content, such as higher refresh rates, HDR, or VRR, without HDMI 2.1 or DisplayPort 1.4.
For HDMI 2.1, you will need a certified Ultra High Speed HDMI cable, which has a bandwidth of 48 Gbps and can support all the features of HDMI 2.1. For DisplayPort 1.4, you can use any standard DisplayPort cable, which has a bandwidth of 32.4 Gbps and can support most of the features of DisplayPort 1.4. However, you may need a certified DisplayPort 1.4 cable if you want to use DSC or MST.
Yes, you can use an adapter or a converter to connect HDMI 2.1 and DisplayPort 1.4 devices, but you may lose some of the features or performance of the original signal. For example, if you use an HDMI to DisplayPort adapter, you may not be able to use VRR or eARC. If you use a DisplayPort to HDMI adapter, you may not be able to use DSC or MST.
HDMI 2.1 and DisplayPort 1.4 offer several benefits for gaming, such as higher resolutions, higher refresh rates, HDR, VRR, and low latency. These features can enhance the visual quality, smoothness, and responsiveness of your gaming experience, especially for next-generation games.
