(or category 2) HDMI cable vs. “Standard”
(or category 1) HDMI cable & HDMI cable replacement,
(or category 2) HDMI cables can successfully handle 1080p
signals (tested to perform at speeds up to 10.2Gbps, increased color depths / refresh rates & accommodate 2560x1600 resolution).
(or category 1) HDMI cables can handle 720p/1080i
signal (tested to perform at speeds up to 2.25Gbps, which is the equivalent of a 720p/1080i signal).
Tip: HDMI 1.4 specification, has five HDMI cable types to choose from:
* “High-Speed” & “Standard” cables are based on HDMI cables “categories 2 &1” recent announcement by: HDMI Licensing, LLC - for more info search “HDMI Licensing, LLC”.
* “High-Speed" (or category 2) HDMI cables are recommended – (with HDMI 1.4 specification).
* Check TVs, AV Receivers, BDPs, STBs & DVPs Owner’s Guide (manual) for HDMI-Cable-Specs requirement (new devices & firmware more likely will require the use of High-speed HDMI cables.
Tip: “High Speed”
- Standard HDMI Cable (supports up to 1080i or 720p video signal).
- Standard HDMI Cable with Ethernet (supports up to 1080i or 720p video signal & HDMI Ethernet Channel-enabled).
- Standard Automotive HDMI Cable (supports up to 1080i or 720p video signal & tested to higher performance standards).
- High Speed HDMI Cable (supports up 1080p and beyond).
- High Speed HDMI Cable with Ethernet (supports up 1080p and beyond & HDMI Ethernet Channel-enabled).
(or "Category 2") HDMI Cable, (
with HDMI 1.4 specification) supports the following:
compliant (HDCP is implemented).
• Deep colour -
support 36-bit mode (& 48-bit mode optional).
color space (also x.v.Color).
• High Definition Audio
- Dolby TrueHD & DTS-HD Master Audio (bitstream capable).
(Audio return channel).
• Auto lip-sync.

(HDMI Ethernet Channel-enabled) or HEAC (HDMI/Ethernet/Audio/Control) - (for High Speed HDMI Cable with Ethernet).
Tip: updated/previous HDMI-CEC commands -
Standard HDMI cable may not support all of the above.
* “High Speed” ("Category 2") certified cables are tested and should perform as expected.
* Non-Certified “High Speed” may perform as expected w/o certification (so, test it well during the return-period).
HDMI control signals - e.g., Pulse [BRAVIA Sync], Samsung [AnyNet+], Panasonic [VIERA Link], [RIHD], Yamaha [HDMI-CEC]:
