🔌 How to choose the right HDMI cable? A simple guide for buyers

HDMI cables look the same, but their capabilities can vary greatly. The right cable can affect video quality, color accuracy, gaming smoothness, and even audio format support. This guide clearly explains how to choose the best HDMI cable for your equipment.

🎯 1. HDMI cable versions: what do they mean?

HDMI 1.4

• Supports 1080p and 4K 30Hz

• Suitable for older TVs, monitors, projectors

• A good choice for simple use

HDMI 2.0

• 4K 60Hz

• HDR support

• Fits most modern TVs

• Optimal for movies and games up to 60 FPS

HDMI 2.1

• 4K 120Hz / 8K 60Hz

• VRR, ALLM, eARC

• Recommended for PS5, Xbox Series X and high-end monitors

⚡ 2. Cable speed (bandwidth) – the most important indicator

Cable type	Sparta	Support
Standard HDMI	4.95 Gbps	720p / 1080i
High Speed HDMI	10.2 Gbps	1080p, 4K 30Hz
Premium High Speed HDMI	18Gbps	4K 60Hz, HDR
Ultra High Speed HDMI	48Gbps	4K 120Hz, 8K

In short:

• 4K TV → Premium High Speed

• PS5 / Xbox Series X → Ultra High Speed

📏 3. Does the length of the cable matter?

Yes — the longer the cable, the greater the chance of signal loss.

• Up to 2 m – any quality cable is suitable

• 3-5 m - choose Premium High Speed

• Above 5m - Active or Optical HDMI recommended

For long cables, the cheapest options often do not work stably.

🖥️ 4. When is HDMI 2.1 necessary?

If you have:

• PS5

• Xbox Series X

• 120 Hz TV or monitor

• Gaming TV with VR

Then HDMI 2.1 is a must, as only it supports 4K 120 Hz and VRR.

🔊 5. Audio format support

HDMI also transmits audio. The most important formats are:

• ARC – audio transmission to soundbar

• eARC – high quality Dolby Atmos, DTS:X

If you have a home theater system, choose HDMI 2.1 with eARC.

✔️ 6. Is it worth overpaying for "gold-plated" cables?

No. Gold plating does not change the image quality — it only protects the connector from oxidation. What matters is certification and speed , not color or brand.

🧩 Conclusion: Which HDMI cable is best for you?

• For movies and TV → HDMI 2.0 (Premium High Speed)

• For games 120 Hz → HDMI 2.1 (Ultra High Speed)

• For long distances → Optical HDMI

• For home theater → HDMI with eARC

A properly selected cable will ensure maximum video and audio potential without additional costs.
