HDMI cables are not all equal. Wrong cable = flickering, no signal, or bandwidth loss. Here's what matters.
HDMI 2.0 vs HDMI 2.1: bandwidth difference
**HDMI 2.0**: 18 Gbps. Handles 4K 60 FPS, 1440p 240 FPS. Older, cheaper ($5–10).
**HDMI 2.1**: 48 Gbps. Handles 4K 120 FPS, 8K 60 FPS. Newer, more expensive ($15–30).
For gaming at 1440p 144Hz or 4K 60Hz, HDMI 2.0 is fine. For 4K 120Hz (next-gen consoles/GPUs), HDMI 2.1 is required.
HDMI 2.0: Up to 50 ft is fine (signal degradation minimal).
HDMI 2.1: Stay under 15 ft for 4K 120Hz (longer cables = signal loss).
For short runs (desk to monitor), any quality cable works. For longer runs, expect bandwidth loss on HDMI 2.1.
Shielding and construction: gold-plated connectors
Gold plating is marketing (doesn't improve signal). What matters: thick cable jacket, ferrite filters (noise reduction), low-resistance connectors.
Brand matters: Belkin, Anker, Amazon Basics are reliable. Ultra-cheap cables ($1) fail.
Best budget HDMI 2.0 cable: Amazon Basics (~$7)
Reliable, certified HDMI 2.0, works for 99% of setups. Most people don't need anything fancier.
Best HDMI 2.1 cable: Belkin Ultra HD (~$25)
Certified 48 Gbps, supports 4K 120Hz, durable. Worth it if you have RTX 4090 or next-gen GPU.

Frequently Asked Questions
Can I use HDMI 2.0 cable with HDMI 2.1 monitor?
Yes, but limited to HDMI 2.0 bandwidth. 4K 120Hz requires HDMI 2.1 cable. Backward compatible but bandwidth capped.
Do expensive HDMI cables sound/look better?
No. HDMI is digital — either works or it doesn't. $25 cable works identically to $3 cable if both are certified. Brand reliability matters, price doesn't.
How often do HDMI cables fail?
Rarely if handled well. Bend stress is the main killer (repeated plugging in/out, tight loops). Keep cables loose, replace every 3+ years if heavily used.
