SCP 991UHD-0.5M — Ultra-slim premium certified 4K HDMI cable
The SCP 991UHD-0.5M is a 0.5 m / 1.6 ft ultra-slim Premium Certified High Speed HDMI cable with Ethernet, engineered for home theater and professional AV installations that demand guaranteed 4K/Ultra HD performance in a compact form factor. ATC-tested and certified under the official HDMI Premium Cable Certification Program, it carries the verifiable anti-counterfeiting label that proves compliance to the 18 Gbps standard. Its exceptionally slim 4.5 mm OD and low-profile connectors make it the go-to choice wherever space is at a premium — behind displays, inside media cabinets, or on multi-port switching equipment. Sold individually in a resealable blister pack, it suits both one-off retrofits and large-quantity professional deployments.
Snug-Tite™ Grip: Stays Connected
HDMI connectors work loose over time — from vibration, cable weight, repeated access, and everyday handling. A loose HDMI connection causes intermittent dropouts, image freeze, or total signal loss. SCP's patented Snug-Tite™ Grip addresses this without the bulk of screw-locks or locking clips, which are awkward on tightly packed multi-port devices. The grip retains 12 lbs of holding force even after many connect/disconnect cycles, so the cable stays put in permanent installations behind wall-mounted displays as well as in mobile rigs that get moved regularly. The result: rock-solid signal integrity and far fewer return visits to fix a 'mysterious' AV fault that turns out to be nothing more than a loose cable.
Officially Premium HDMI Certified
Not all cables claiming 4K support are independently verified. This cable has been tested by an Authorised Testing Centre (ATC) and certified under the HDMI Premium Cable Certification Program, confirming full 18 Gbps bandwidth and compliance with HDMI 2.0b. The resealable blister pack carries an encrypted anti-counterfeiting label with a QR code readable by the free HDMI Premium Cable App — giving end customers instant, phone-based proof that they have a genuine, performance-verified cable. For AV integrators, this certification removes all ambiguity when specifying cables for 4K HDR systems: there is no 'will it work?' guesswork, and the label provides a tangible quality mark that clients can see and verify themselves.
Ultra-Slim for Tight Installations
At just 4.5 mm OD and with a deliberately low-profile connector housing, the 991UHD slots into cramped spaces where standard-gauge HDMI cables simply do not fit: behind flush-wall-mounted displays, inside shallow media cabinets, and on densely populated AV receivers or matrix switchers where adjacent ports compete for room. The thinner cable also reduces strain on the HDMI port itself — a practical benefit in permanent installations where the cable hangs or is routed over a distance. The 0.5 m length specifically targets source-to-display connections that sit close together, keeping cable runs tidy and eliminating unnecessary slack.
Triple Shielding for EMI-Sensitive Environments
Higher-frequency 4K signals are more susceptible to electromagnetic interference than 1080p, particularly in rack rooms and server environments where dense cabling, switching power supplies, and wireless devices all generate RF noise. The 991UHD uses triple shielding on both the cable and the connectors, providing a significantly higher level of EMI attenuation than standard single- or double-shielded designs. This matters in commercial AV installations — boardrooms, control rooms, retail displays, digital signage racks — where an unshielded cable can introduce visual artefacts or signal degradation that is difficult to diagnose. The UL CL2 / FT4 in-wall rating adds further confidence for permanent in-wall or plenum-adjacent routing.
