StarTech HDMIPLATE In-Wall HDMI Pass-Through Wall Plate

Overview

The StarTech HDMIPLATE is a single-gang in-wall HDMI connection plate designed for integrators who need a clean, finished HDMI termination point without exposed cable runs. It fits a standard single-gang electrical box, accepts one HDMI source connection on the back, and presents a flush HDMI port on the wall face — the difference between a professional AV installation and a cable draped along a baseboard. At 4.4 in x 2.8 in x 1.2 in and just 1.4 oz, it drops into nearly any existing single-gang rough-in without modification. If you are specifying StarTech AV connectivity products for a room build-out, this is the plate that closes the loop on a tidy wall drop.

Key Features

• Single-Gang Box Mount: Drops directly into any standard single-gang electrical box — the same box profile used throughout commercial and residential construction. No custom cutout, no adapter plate needed. That means a clean retrofit into existing infrastructure without drywall work.
• HDMI-to-HDMI Pass-Through (19-Pin Both Sides): Full 19-pin HDMI connector on both the wall face and the back-of-plate connection point. The signal path is a straight mechanical coupler — no active components, no signal processing — so whatever HDMI version your source and display support is what travels through the wall. No conversion bottleneck introduced by the plate itself.
• Compact Footprint (4.4 in x 2.8 in x 1.2 in): The 1.2-inch depth is the spec to watch. Shallow single-gang boxes — common in commercial retrofits — can run as shallow as 2 inches. At 1.2 inches of plate protrusion into the box, there is enough clearance for the rear HDMI connector and a standard patch cable pigtail. Measure your box depth before ordering if you are working with especially shallow rough-ins.
• White Finish: The white color matches standard decora-style plates and blends with commercial interior finishes. Not a specialty finish, but appropriate for most boardrooms, classrooms, and presentation spaces where the plate should disappear into the wall.
• Lightweight Construction (1.4 oz / 40 g): The low weight means the plate does not stress the gang box mounting screws over time — a minor but real consideration when plates are installed in high-traffic areas where connectors are plugged and unplugged repeatedly.
• Lifetime Warranty: StarTech backs the HDMIPLATE with a lifetime warranty. For a passive mechanical component installed inside a finished wall, this matters — you are not pulling drywall to replace a plate that fails prematurely.

Integration and Compatibility

The HDMIPLATE is passive — it introduces no electronics between source and display, which means it is compatible with any HDMI signal: 4K, 1080p, ARC, eARC, HDMI 2.0, HDMI 2.1 — whatever the cable running through the wall supports. The limiting factor is always the cable, not this plate. Pair it with a high-speed or ultra-high-speed HDMI cable rated for the bandwidth your application requires. This plate is also a natural complement to any AV cable infrastructure build-out where in-wall routing is part of the design. For conference rooms, training spaces, and huddle rooms, this plate works alongside HDMI extenders when the display is further than a direct cable run can manage. For AV-over-IP deployments where the wall drop terminates at a balun or encoder, the HDMIPLATE provides the tidy physical interface at the wall before the signal conversion happens. It does not support keystone snap-in inserts — the HDMI ports are fixed and not interchangeable with other connector types.

Frequently Asked Questions

Q: Will the HDMIPLATE support 4K HDMI signals?

A: Yes. The HDMIPLATE is a passive mechanical coupler with full 19-pin HDMI connectors on both sides. It introduces no active electronics, so bandwidth is determined entirely by the cable running through the wall. Use a high-speed or ultra-high-speed HDMI cable rated for 4K (18 Gbps) or 4K 120Hz (48 Gbps) and the plate will not be the limiting factor.

Q: What gang box size does the HDMIPLATE fit?

A: The HDMIPLATE mounts to a standard single-gang electrical box — the most common box size in commercial and residential construction. No adapter or special box is required.

Q: How deep does the box need to be to accommodate the HDMIPLATE?

A: The plate itself is 1.2 inches (3.0 cm) deep. You need enough remaining box depth to accommodate the rear HDMI connector and a patch cable pigtail. Measure your rough-in box before ordering if you are working with shallow single-gang boxes.

Q: What is the warranty on the HDMIPLATE?

A: StarTech provides a lifetime warranty on the HDMIPLATE.

Q: Can the HDMIPLATE accept keystone inserts for other connector types?

A: No. The HDMIPLATE has fixed HDMI ports and is not a keystone-style plate. It accepts only HDMI connections and cannot be reconfigured for USB, Ethernet, or other connector types.

Q: Does the HDMIPLATE work with HDMI ARC or eARC?

A: Yes. Because it is a fully passive 19-pin HDMI coupler, it passes all signals present on the HDMI pins including ARC and eARC — provided the cable and connected devices support those features.

Ted Perry

The HDMIPLATE is one of those parts that gets overlooked in a BOM until the integrator is standing in front of a finished wall with a cable dangling out of a hole. At 1.2 inches of back-depth and a single-gang footprint, the HDMIPLATE fits the rough-ins already in the wall — no special ordering, no drywall surprises. That passive 19-pin coupler is the right call for permanent wall drops where you want zero active components to fail or require firmware updates five years down the road.

Technical Highlights:

• Passive 19-Pin HDMI Coupler: No electronics in the signal path means no latency, no handshake issues, and no compatibility ceiling — the plate passes whatever HDMI version the cable and endpoints negotiate.
• 1.2-Inch Back Depth: Tight enough to fit most commercial single-gang boxes, but verify depth on shallow retrofit boxes — anything under 2.5 inches total box depth warrants a measurement before install.
• Lifetime Warranty: For a plate installed inside a finished wall, a lifetime warranty removes the worst-case scenario: pulling drywall to swap a failed passive component.

Deployment Considerations:

• The HDMIPLATE is a fixed-port plate — plan your connector type at design time. If there is any chance the wall drop will need to support USB-C or Ethernet in the future, a keystone-style plate with a modular insert system is a better long-term choice.
• Cable quality through the wall determines everything. The plate is passive, so a cheap in-wall cable at 4K distances will show signal integrity issues that a more expensive cable would not — budget the cable, not just the plate.

For a boardroom or training room build-out where the AV consultant has already spec'd a fixed HDMI wall drop and the finish schedule calls for a clean white decora-style plate, the HDMIPLATE is the straightforward answer — install it, forget it, and move on to the rest of the job.
