HDMI cables help us enjoy the best possible picture and sound quality from our TVs, Blu-ray players, A/V receivers, and other home theater gear. But all HDMI cables are not created equal. On-Q's Premium HDMI cables are among the first to be certified to handle the highest-quality signals, including 4K Ultra HD video and HDR (High Dynamic Range).
The creators of HDMI technology have developed a new cable testing and authentication process: The Premium HDMI Cable Certification Program. Cables are tested to make sure they support the full 18 Gbps bandwidth provided by the HDMI 2.0 specification. Plus, an EMI test ensures that cables minimize interference with wireless signals. Finally, every length of every model line must pass the tests to receive certification.
The certification program also includes a special authentication label placed on every certified product. It's a response to all the counterfeit and no-name cables on the market that claim performance that they don't actually deliver.
Should you get a Premium HDMI cable?
If your current HDMI cable isn't doing its job, you'll know. HDMI failure causes very visible picture problems: dropped-out pixels called "sparkles," a picture that flashes or jumps, or no picture at all. An inadequate HDMI cable doesn't affect qualities like sharpness, contrast, or color.
At lengths of a few meters or less, any well-made "high-speed" HDMI cable should work fine in most 4K applications. But if you're connecting an Ultra HD Blu-ray player to a 4K TV — especially a longer run — a Premium HDMI cable will guarantee flawless performance.
