Why Most HDMI Cables Fail in 2025
Old “High Speed” HDMI cables (18Gbps) can’t handle 8K, 4K@120Hz gaming or advanced audio formats. You need a certified Ultra High Speed HDMI 2.1 cable (48Gbps) with the official hologram label. Anything else = stuttering, black screens, no HDR, or no eARC for your soundbar.
