In 2 Minutes
- Under 5 m length: An 8-€ cable delivers identical signal as an 80-€ cable. Digital transmission knows no "better".
- HDMI version: 2.0 is enough for Full HD, 2.1 only for 4K at 120 Hz.
- Over 10 m: Look for "High Speed with Ethernet" or active cable with signal booster.
- Gold connectors, thick shielding: Marketing features with no measurable effect in home use.
You're standing in the electronics store looking at HDMI cables from 6 € to 120 €. The sales rep sells you the expensive one with "interference-free, 4K-proof, gold connectors" — and you suspect it's rubbish. It is. In 5 minutes you'll know which cable is actually right for your projector.
The most important sentence: HDMI is digital
Analog cables transmit signals with loss. Thicker cables, better shielding, and gold connectors make a difference there. HDMI is digital — the signal either arrives correctly or not at all. Nothing in between.
In practice: An 8-€ standard cable and an 80-€ premium cable show exactly the same picture at the same length and same HDMI version. Anyone claiming otherwise is selling marketing.
Which HDMI version you really need
| Version | Maximum | For whom |
|---|---|---|
| HDMI 1.4 | Full HD @ 60 Hz | Old, avoid |
| HDMI 2.0 | 4K @ 60 Hz | Mainstream standard |
| HDMI 2.0b | 4K @ 60 Hz + HDR | Home cinema optimal |
| HDMI 2.1 | 8K @ 60 / 4K @ 120 Hz | Gaming enthusiasts |
For a Full HD projector like the PIXORA One, any HDMI 2.0 cable will do. Anything more gives you nothing technically.
Length: The only point that really matters
With HDMI cables, length determines signal quality — not price. Limits based on practical experience:
- Up to 5 m: Any standard cable works. 8–15 € is appropriate.
- 5–10 m: Look for "High Speed". Price 15–30 €.
- 10–15 m: Active HDMI cable with signal booster required. 30–60 €.
- Over 15 m: Fiber optic HDMI (Optical) — pricier, but signal-stable up to 50 m.
Tech Tip
With ceiling mounting, you often calculate 7–12 m cable run. More important than price is the directional label: active cables have a source connector (projector input or source) and a sink connector (display). Connected the wrong way, the signal won't work. Usually printed directly on the connector.

Marketing terms you can ignore
Seven sales claims that mean nothing technically:
- "Gold connectors": Reduces corrosion long-term. Irrelevant for image quality.
- "24k gold-plated": Same thing in marketing speak. Marginal.
- "4K-proof" without version info: Empty claim. Demand HDMI 2.0 or higher.
- "Interference-free": Digital transmission is by definition interference-free — or it doesn't work.
- "Triple shielding": At 2 m length, completely oversized.
- "Oxygen-free copper (OFC)": Has no effect on digital signals.
- "Audiophile cable": Don't exist with HDMI. HDMI carries audio digitally — 0 or 1.
What you should actually pay attention to
- HDMI version (2.0 is enough, 2.0b for HDR).
- Length — as short as possible, but with 30 cm buffer.
- Certification "High Speed with Ethernet" from 5 m on.
- Connector shape — some projectors have tight spaces, then right-angle connector needed.
- Return option in case the cable isn't compatible.
Bottom line: Your next step
Don't buy an expensive HDMI cable if you need under 5 m. A 10-€ standard cable with HDMI 2.0 certification gives you identical image as an 80-€ premium model. Better to invest that money in a better projector or a soundbar.
We tested standard and premium cables side by side ourselves — the visible difference: zero. You'll find the right selection in our accessories section.

Frequently asked questions about HDMI cables
Does it have to be an expensive HDMI cable?
No. Under 5 meters, the difference between an 8 € and 80 € cable is unmeasurable. Digital signals transmit correctly or not at all — the expensive cable brings you no visual benefit.
How long can the cable be maximum?
Standard HDMI up to 10 meters for Full HD. For 4K over 5 meters you need active cables (with built-in booster) or certified HDMI 2.1. Longer distances become error-prone.
Is HDMI 1.4 enough or must it be 2.1?
HDMI 1.4 is fine for Full HD at 60 Hz. For 4K at 60 Hz you need HDMI 2.0, for 4K/120 Hz (gaming) HDMI 2.1. Check what your projector supports.
Are ferrite cores or shielding important?
On longer runs or electrically noisy environments (old house wiring, fluorescent lights), shielding helps prevent picture flicker. Unnecessary in a normal living room.
Which cable for on-the-go or flexible use?
A soft, flexible HDMI 2.0 cable in 3 m length covers almost all everyday scenarios. For mobile setups with frequent plugging/unplugging, the cable should have reinforced connectors.
