4K HDMI Cable (Blue Connector) - 1.5m

HDMI-1-5M

4K HDMI Cable (Blue Connector). Length 1.5m.

Type: HDMI
Length: 1.5 m
Connectors: HDMI

In-depth technical details

HDMI Type-A carries 19 pins: TMDS pairs for the picture/sound itself, plus CEC, DDC/+5V and HPD control lines. The exact HDMI generation (1.4 vs 2.0 vs 2.1) is not confirmed for this specific product line -- the supplier invoice does not state it, so no bandwidth/resolution ceiling is claimed here until confirmed.

Connector anatomy

HDMI Type-A

01 19 pins Three differential TMDS pairs carry picture and sound, a fourth carries the clock, and the rest are named-function pins.
02 CEC A single wire that lets one remote control multiple connected devices, e.g. a TV and a receiver.
03 DDC / +5V The EDID handshake -- how the source learns which resolutions the display supports.
04 HPD Hot Plug Detect -- how the source knows a display is connected at all.
05 Metal shell The shell is grounded and wraps the pins, keeping interference out of a very high-frequency signal.
06 Strain-relief boot Stops the wires flexing where they leave the plug — the exact point most cables fail.
07 Outer jacket The outer sheath protecting the conductors inside from abrasion and moisture.

How it works

HDMI cable construction

The picture goes out on three differential pairs, each carrying the signal and an inverted copy. The display subtracts one from the other, so any noise that hit both wires cancels out. The fourth pair carries the clock that says when each pixel starts.

01 4 shielded pairs Three carry data (TMDS), one carries the clock. Each pair is individually shielded because these frequencies run into the gigahertz.
02 Control wires The DDC channel reads what the display can do, CEC lets one remote control every device, plus a 5 V line.
03 Shield A grounded conductive wrap that absorbs electromagnetic interference before it reaches the signal.
04 Outer jacket Protects everything inside mechanically. It plays no electrical role.

From the published standard

How it works

An HDMI cable carries picture and sound digitally over three differential pairs using TMDS encoding, with a fourth pair for the clock. The signal is digital, so it either arrives intact or drops out, and does not degrade gradually the way VGA does. The version printed on a cable is what sets the maximum resolution it can pass, and the supplier has not yet confirmed that figure for this item.

Signal: Digital, TMDS-encoded over three differential pairs
Behaviour at the limit: Drops out rather than degrading gradually
Connector: HDMI Type-A, 19 pins
