This FAQ answers the questions buyers ask most often about choosing and sourcing hdmi cables when sourcing directly from a manufacturer. It reflects how we work at Tonetron (Dongguan Taitron Electronic Limited). Project-specific figures such as minimum order quantity, sample and tooling costs and lead times vary by product and volume, so where a number would depend on your order we say "request a quote" rather than publish a figure that would not apply to your case.
Choosing and sourcing HDMI™ cables
What is the difference between HDMI™ version and HDMI™ cable class?
The HDMI™ version (2.0, 2.1, 2.2) describes the capability of the specification and devices; the cable class (High Speed, Premium High Speed, Ultra High Speed) describes what a cable is certified to carry. To reach 48 Gbps for 8K, you need an Ultra High Speed certified cable, not just an "HDMI™ 2.1" label.
Which HDMI™ cable do I need for 4K and for 8K?
For 4K at 60 Hz, an 18 Gbps HDMI™ 2.0-class (Premium High Speed) cable is sufficient and cost-effective. For 8K at 60 Hz, 4K at 120 Hz, gaming and high color depth, specify an Ultra High Speed (48 Gbps) HDMI™ 2.1 certified cable.
Are your HDMI™ 2.1 cables certified?
These models hold HDMI™ 2.1 test confirmations from a third-party HDMI Forum Authorized Test Center (ATC): PF331S-0150, PF331S-0300, PF331A-0180, PF331A-0300, PF331A-0500, PLT331C-0180 and TT-1.8-2.1. We are not an ATC, and our cables are not in the Ultra High Speed cable certification list. Confirm the tested model when requesting a quote.
Does a longer HDMI™ cable affect picture quality?
At high bandwidth, yes. Length, shielding and connector quality all determine whether a link sustains its rated bandwidth. This matters most at 8K and above, which is why certified construction and adequate shielding are important for longer runs.
Can you customize HDMI™ cables for our brand?
Yes. We offer OEM/ODM: custom lengths, connector plating (for example 24K gold-plated), jacket material (nylon braided, PVC), shell material, printed logos and private-label retail packaging. Share your specification for a quote.
