Solved: Do I Really Need HDMI 2.1 for PS5 and Xbox Series X?

HDMI 2.1 introduces a range of features that are advantageous for gaming, particularly for next-generation consoles like the PS5 and Xbox Series X. However, whether you “need” HDMI 2.1 depends on what you want from your gaming experience. Let’s break down the benefits and considerations:

Benefits of HDMI 2.1 for PS5 and Xbox Series X:

  1. Higher Resolutions and Faster Refresh Rates: HDMI 2.1 supports up to 8K resolution at 60Hz and 4K resolution at 120Hz. This means games designed to run at 4K and 120fps can only achieve their full potential with an HDMI 2.1 connection.
  2. Variable Refresh Rate (VRR): This feature reduces screen tearing in games, ensuring smoother visuals.
  3. Auto Low Latency Mode (ALLM): ALLM automatically switches your TV to its low-latency game mode when it detects a game signal, optimizing the gaming experience.
  4. Enhanced Audio Return Channel (eARC): eARC supports the most advanced audio formats and the highest audio quality, ensuring you get the best sound quality to match your visuals.
  5. Quick Frame Transport (QFT): Reduces latency for smoother no-lag gaming and real-time interactive virtual reality.


  1. Current TV Specs: If your current TV or monitor doesn’t support HDMI 2.1 and you don’t plan to upgrade soon, you won’t benefit from the enhanced features. The PS5 and Xbox Series X will still work with HDMI 2.0, but with limitations on refresh rates and resolution.
  2. Game Requirements: Not all games will take advantage of 4K at 120fps. Many games might run at 4K 60fps or even lower resolutions and frame rates.
  3. Cable Quality: To benefit from HDMI 2.1 features, you need a high-quality cable that supports the bandwidth requirements of HDMI 2.1.
  4. Budget and Longevity: Investing in HDMI 2.1 could be seen as future-proofing, especially if you’re looking to buy a new TV or monitor soon.


Aspect Details
Benefits Support for higher resolutions and refresh rates, VRR, ALLM, eARC, and QFT.
Limitations with HDMI 2.0 Limited to 4K at 60fps, might not support advanced features like VRR.
Game Requirements Not all games will utilize the full capabilities of HDMI 2.1.
Future-Proofing HDMI 2.1 might become more standard in future game requirements and TV/monitor releases.

In conclusion, while HDMI 2.1 provides clear advantages for gaming on next-gen consoles, you don’t strictly “need” it unless you’re aiming for the highest resolutions and refresh rates, and you have the hardware to support it. However, as more games and entertainment content take advantage of HDMI 2.1’s features, having a compatible setup could enhance your gaming and viewing experience in the future.
