When Do You Need an 8K HDMI Cable?
Not everyone needs HDMI 2.1. Here’s when an 8K cable matters:
You have an 8K TV or plan to upgrade soon
You’re gaming at 4K@120Hz on PS5, Xbox Series X, or high-end PCs
You use eARC for high-quality audio systems
You want future-proofing for new devices and media standards
