Key takeaways

  • Bandwidth: HDMI 2.1 boasts a colossal 48 Gbps bandwidth, enabling up to 8K at 60Hz or 4K at 120Hz with full color depth. DisplayPort 1.4, while still robust at 32.4 Gbps, typically caps out at 8K 60Hz or 4K 120Hz with Display Stream Compression (DSC).
  • Variable Refresh Rate (VRR) Support: Both standards support VRR technologies like FreeSync and G-Sync. HDMI 2.1 has its own standardized VRR implementation, while DisplayPort relies on its respective adaptive sync protocols.
  • Multi-Monitor Support: DisplayPort’s Multi-Stream Transport (MST) technology is a significant advantage for creating dual or even triple monitor setups from a single port. HDMI typically requires multiple ports on the GPU for multiple displays.
  • Audio Return Channel (ARC/eARC): HDMI excels with advanced audio capabilities like ARC and eARC, allowing audio to be sent back from a display to a soundbar or receiver. DisplayPort’s audio capabilities are generally more basic.
  • Connector Type: HDMI uses its familiar, compact connector, while DisplayPort features a slightly larger connector with a locking mechanism, offering more security.
  • Target Use Case: HDMI 2.1 is increasingly favored for next-gen consoles and high-end TVs, while DisplayPort remains a strong choice for PC gaming, especially with its multi-monitor and professional workstation applications.

Quick Verdict

For the absolute cutting edge in gaming performance, particularly at resolutions like 4K and beyond with high refresh rates (120Hz+), HDMI 2.1 is the current king. However, DisplayPort remains a formidable and often more versatile option, especially for multi-monitor configurations and users who don’t necessarily require the absolute maximum bandwidth HDMI 2.1 offers. DisplayPort 1.4 is still more than capable for most 4K 120Hz gaming scenarios, and its MST capabilities are a major advantage for certain setups.

Key Differences

  • Bandwidth: HDMI 2.1 boasts a colossal 48 Gbps bandwidth, enabling up to 8K at 60Hz or 4K at 120Hz with full color depth. DisplayPort 1.4, while still robust at 32.4 Gbps, typically caps out at 8K 60Hz or 4K 120Hz with Display Stream Compression (DSC).
  • Variable Refresh Rate (VRR) Support: Both standards support VRR technologies like FreeSync and G-Sync. HDMI 2.1 has its own standardized VRR implementation, while DisplayPort relies on its respective adaptive sync protocols.

DisplayPort’s Strengths for Gaming

DisplayPort, particularly the 1.4 standard, continues to be a workhorse for PC gamers. Its 32.4 Gbps bandwidth is more than sufficient for most current gaming demands, comfortably handling 4K resolutions at 120Hz, especially when paired with DSC. The key differentiator for many PC users is DisplayPort’s native support for Multi-Stream Transport (MST). This allows a single DisplayPort output on your graphics card to drive multiple independent displays. Products like the DisplayPort to Dual HDMI Splitter 4K@60Hz, USB-C Powered, DisplayPort 1.4 MST Hub DP to HDMI 1 in 2 Out Splitter for Dual Monitors Extended/Clone Mode for Desktop PC Graphics Card Home Office Gaming are prime examples of how MST can expand your gaming real estate without needing multiple GPU ports. This is invaluable for streamers or anyone who enjoys a wide field of view in supported games or simply needs more screen real estate for productivity alongside gaming.

Furthermore, DisplayPort 1.4 offers excellent HDR support and high refresh rate capabilities. For those looking to connect a DisplayPort source to an HDMI 2.1 display, specific cables like the DisplayPort to HDMI 2.1 Cable 6.6FT 8K@60Hz 4K@120Hz Uni-Directional DP (Source) to HDMI (Display) Braided Cord Supports HDCP 2.3 HDR10 Display Port for AMD,NVIDIA,and PC are essential to ensure compatibility and unlock the full potential of both devices. These cables are designed to translate the DisplayPort signal to an HDMI 2.1 compatible format.

HDMI 2.1: The New Frontier

HDMI 2.1 represents a significant leap forward in bandwidth, reaching a staggering 48 Gbps. This allows for uncompressed 8K at 60Hz and 4K at an astonishing 120Hz, with the potential for even higher refresh rates at lower resolutions. For console gamers, particularly those with the latest PlayStation 5 or Xbox Series X/S, HDMI 2.1 is the de facto standard for experiencing games at their highest fidelity. The bandwidth also supports advanced features like Dynamic HDR and ALLM (Auto Low Latency Mode), which automatically optimizes your display for gaming by reducing input lag.

While not typically used for multi-monitor setups in the same way as DisplayPort’s MST, HDMI 2.1’s raw power is geared towards single, ultra-high-performance displays. If your primary goal is to achieve the highest possible frame rates and resolutions on a single, top-tier gaming monitor or TV, HDMI 2.1 is the clear winner. The compatibility between HDMI 2.1 sources and displays is generally straightforward, provided both devices support the standard. The key is to ensure you’re using certified HDMI 2.1 cables that can handle the full 48 Gbps bandwidth.

Which Should You Buy?

  • For PC gamers prioritizing multi-monitor setups or seeking a versatile connection: DisplayPort is likely your best bet, especially if your graphics card supports DP 1.4 and MST.
  • For console gamers or those with high-end 4K 120Hz+ monitors/TVs aiming for maximum performance on a single display: HDMI 2.1 is the standard to aim for.
  • If your graphics card has only DisplayPort outputs and you need to connect to an HDMI 2.1 display: Ensure you invest in a high-quality DisplayPort to HDMI 2.1 adapter or cable, like the Warrky 4K DisplayPort to HDMI Cable, 6FT 2 Pack, Uni-Directional DP to HDMI.
  • If you need to split a single DisplayPort signal to two HDMI displays for extended/clone mode (and 4K@60Hz is sufficient): Look for MST hubs like the DisplayPort to Dual HDMI Splitter 4K@60Hz.
  • For future-proofing and the absolute highest potential resolutions and refresh rates: HDMI 2.1 offers the most headroom.
