The Short Answer: HDMI or DisplayPort?

The rule of thumb is simple: DisplayPort is the undisputed choice for PC gaming monitors, offering native support for high refresh rates and adaptive sync. HDMI is the universal standard for everything else, making it the required cable for living room TVs, home theater audio, and modern consoles like the PS5 and Xbox Series X.

Understanding the Basics

What is HDMI (High-Definition Multimedia Interface)?

Introduced in the early 2000s by a consortium of electronics manufacturers, HDMI was built to be the single, universal cable for the living room. It was designed to carry both high-quality video and audio over a single wire, replacing the messy web of component cables. Because it was pioneered by brands like Sony, Panasonic, and Toshiba, it is the default connection for consumer electronics.

What is DisplayPort?

DisplayPort was developed a few years later by VESA (Video Electronics Standards Association)—a group focused heavily on the computing industry. It was designed specifically to replace older PC connections like VGA and DVI. While you won't find DisplayPort on your living room television, it is the absolute gold standard for PC graphics cards and high-end desktop monitors.

Core Differences: HDMI vs. DisplayPort

Bandwidth, Resolution, and Refresh Rates

At a fundamental level, both cables transmit data. The "pipe" that data travels through is measured in bandwidth. Higher bandwidth means you can push higher resolutions (like 4K or 8K) and faster refresh rates (like 120Hz, 144Hz, or 240Hz). Historically, DisplayPort always stayed one step ahead of HDMI in raw bandwidth. However, with the release of HDMI 2.1, both cables now offer incredible speeds that exceed the needs of the average consumer, making them neck-and-neck in raw visual fidelity for most setups.

Audio Capabilities and ARC/eARC

Both cables carry audio, but HDMI is the undisputed champion of home theater sound. HDMI features ARC (Audio Return Channel) and its upgraded version, eARC. This allows your TV to send high-quality, uncompressed audio (like Dolby Atmos) back down the cable to a soundbar or AV receiver. DisplayPort cannot do this.

Multi-Monitor Setups and Daisy Chaining

DisplayPort has a unique trick up its sleeve called Multi-Stream Transport (MST), more commonly known as "daisy chaining." If you are building a home office with multiple monitors, DisplayPort allows you to plug your PC into Monitor A, and then plug Monitor A directly into Monitor B. This significantly reduces cable clutter, saving you from running multiple cables all the way back to your computer.

Cable Versions Compared (The Spec Breakdown)

HDMI 2.0 vs. HDMI 2.1

• HDMI 2.0: The older standard, capable of 4K resolution at 60Hz. It is perfectly fine for basic streaming boxes, older consoles, and standard office monitors.
• HDMI 2.1: A massive leap in bandwidth. It supports 4K resolution at 120Hz (and up to 8K at 60Hz). If you want to utilize the full power of current-generation gaming consoles or high-end TVs, HDMI 2.1 is a strict requirement.

DisplayPort 1.4 vs. DisplayPort 2.1

• DisplayPort 1.4: The current standard found on most gaming monitors and graphics cards. It easily handles 4K at 144Hz with compression, making it more than enough for the vast majority of PC gamers.
• DisplayPort 2.1: The bleeding edge of display technology, offering nearly three times the bandwidth of DP 1.4. It supports extreme resolutions and refresh rates (like 8K at 165Hz or 4K at 480Hz). It is currently limited to top-tier, enthusiast hardware.

Which Cable is Best for Your Setup?

Best for PC Gaming on a High-End Monitor

Recommendation: DisplayPort

If you are plugging a desktop graphics card into a gaming monitor, use DisplayPort. It offers the most stable, bug-free experience for incredibly high refresh rates. Furthermore, it natively supports adaptive sync technologies like NVIDIA G-Sync and AMD FreeSync, which communicate with your graphics card to eliminate screen tearing during intense gameplay.

Best for PlayStation 5 and Xbox Series X

Recommendation: HDMI 2.1

Modern gaming consoles do not have DisplayPort connections. To unlock the full potential of a PS5 or Xbox Series X—specifically 4K gaming at 120 frames per second—you absolutely must use an HDMI 2.1 cable plugged into an HDMI 2.1 port on your display.

Best for Home Theater and Living Room TVs

Recommendation: HDMI

Televisions simply do not feature DisplayPort inputs. HDMI is designed specifically for this ecosystem. If you route your audio through a soundbar or AV receiver, HDMI ARC/eARC is necessary to pass the audio signal seamlessly through the TV.

Frequently Asked Questions (FAQ)

Does a better HDMI cable improve image quality?

No. Expensive, "gold-plated," or premium HDMI cables do not make colors richer or images sharper. Because HDMI sends a purely digital signal (ones and zeros), it either arrives perfectly, or it doesn't. If a cable is faulty or lacks the bandwidth for your settings, you will see screen dropouts, black screens, or visual "snow." However, upgrading to a higher specification cable (like moving from an older HDMI 2.0 to a new HDMI 2.1 cable) is absolutely necessary if you want to unlock higher resolutions like 4K at 120Hz.

Is DisplayPort to HDMI the same as HDMI to DisplayPort?

No, adapter cables are strictly directional. A "DisplayPort to HDMI" cable is designed to connect a PC (DisplayPort output) to a TV or monitor (HDMI input). If you plug it in backward, you will get a black screen. If you are trying to connect an HDMI source (like an Xbox or PlayStation) to a DisplayPort monitor, you must buy a specific "HDMI to DisplayPort active adapter." These are less common, more expensive, and usually require an extra USB cable plugged into the wall for power.

What happens if I use a DisplayPort to HDMI adapter?

You will successfully get a picture and audio, but your performance will be bottlenecked by the adapter itself. The connection is only as fast as the weakest link. For example, even if your graphics card and your TV support 4K at 120Hz, a standard adapter might limit your output to 60Hz. Furthermore, running your signal through an adapter will almost always disable PC-specific features like NVIDIA G-Sync or AMD FreeSync.

Is it better to run DisplayPort or HDMI?

Neither is universally "better"—it entirely depends on the hardware you are connecting. If you are plugging a high-end desktop computer into a gaming monitor, DisplayPort is the better choice for stability and high refresh rates. If you are plugging a game console, streaming box, or laptop into a living room television, HDMI is the best (and often only) choice.

Can I plug a DisplayPort cable directly into an HDMI port?

Not without an adapter. The physical shapes of the ports are different. DisplayPort has one flat edge and one angled edge, while HDMI has two angled edges.

Does DisplayPort affect FPS?

The cable itself doesn't generate frames—your graphics card does. However, if your cable lacks the bandwidth to carry those frames, your monitor won't display them. For example, if your PC generates 144 FPS but you are using an older HDMI 2.0 cable capped at 60Hz at 4K, you will only see 60 frames per second. DisplayPort ensures the "pipe" is wide enough so you aren't bottlenecking your graphics card.
