If youโ€™ve ever blamed your controller or internet for a missed FPS clutch, you might be targeting the wrong culprit. Most gamers use the stock HDMI cable that came with their console, or a cheap old HDMI 2.0 cord lying around, and donโ€™t realize itโ€™s kneecapping their PS5/Xboxโ€™s full performance.
This 3-minute guide breaks down exactly how low-latency HDMI 2.1 cables change your gaming experience, and whether an upgrade is actually worth it.

Quick Tech Breakdown: What Makes Low-Latency HDMI 2.1 Different?

Before we dive into performance gains, hereโ€™s a no-fluff comparison of standard HDMI 2.0 vs. certified low-latency HDMI 2.1 cables, built specifically for console gaming:

Feature Standard HDMI 2.0 Certified Low-Latency HDMI 2.1
Max Bandwidth 18Gbps 48Gbps
Max Gaming Resolution/Refresh Rate 4K@60Hz 4K@120Hz / 8K@60Hz
Typical Console Input Lag 20โ€“50ms 8โ€“15ms
Supports VRR (Variable Refresh Rate) โŒ No โœ… Full native support
Supports ALLM (Auto Low Latency Mode) โŒ No โœ… Auto-triggers TV game mode
eARC Surround Sound Support โš ๏ธ Optional (often laggy) โœ… Native (zero audio sync delay)
Unlocks All PS5/Xbox Features โŒ No โœ… Yes

 

3 Key Performance Impacts for PS5 & Xbox

1. Cut Input Lag for Competitive Wins

For FPS, fighting, and rhythm games, even 10ms of lag is the difference between landing a headshot and getting eliminated. Low-latency HDMI 2.1 cables reduce signal processing delay by 60% on average compared to HDMI 2.0, and fully unlock your consoleโ€™s ALLM (Auto Low Latency Mode) feature to automatically disable your TVโ€™s unnecessary image processing when you launch a game.

2. Unlock Full 4K/120Hz + VRR Visuals

If you own a 4K 120Hz TV, your HDMI 2.0 cable is wasting half your displayโ€™s potential. HDMI 2.1โ€™s 48Gbps bandwidth supports uncompressed 4K@120Hz gameplay for titles likeย Cyberpunk 2077: Phantom Liberty,ย Hogwarts Legacy, andย Street Fighter 6, plus full VRR functionality to eliminate screen tearing and stutter during fast-paced open-world gameplay.


Note: The stock HDMI cable included with PS5/Xbox is a basic HDMI 2.1 cord, but it will fail to deliver stable 4K/120Hz for runs longer than 2 meters.

3. Eliminate Signal Dropouts & Audio Sync Issues

HDMI 2.0โ€™s limited bandwidth canโ€™t handle high-bitrate features like 8K gaming (upcoming for PS5 Pro), Dolby Vision gaming, or eARC surround sound for soundbars. Low-latency HDMI 2.1 cables eliminate mid-game signal drops, flickering when enabling VRR, and audio sync delays when using surround sound for competitive gameplay.

Quick Upgrade Checklist: Do You Actually Need to Buy a New Cable?

โœ… Upgrade if you check any of these:
  • You own a 4K@120Hz / 8K display with HDMI 2.1 ports
  • You regularly play competitive FPS, fighting, or action games
  • You canโ€™t enable 120Hz/VRR mode on your console, or experience screen flickering
  • You use an eARC soundbar for gaming and deal with audio sync issues

 

โŒ No upgrade needed if:
  • Your display only supports 1080p or 4K@60Hz with no HDMI 2.1 ports
  • You only play casual single-player games and donโ€™t prioritize minor lag differences
