Product Features
Technical Overview
This HDMI splitter implements HDMI 2.0b specification with support for 4:4:4 chroma subsampling, HDR content, and HDCP 2.2 to HDCP 1.4 conversion. The 18Gbps bandwidth capacity ensures smooth transmission of high-resolution content without compression artifacts. The built-in scaler allows independent resolution management for each output display, while EDID copy functionality simplifies configuration by replicating display settings across multiple monitors.
Audio flexibility is a key technical advantage, with simultaneous output through HDMI, 3.5mm analog jack, and optical digital port. The integrated Digital-to-Analog Converter (DAC) enables direct connection to analog audio systems. Passive HDMI cables can reach up to 16.4 feet (5 meters) without signal degradation, while the device remains compatible with active cables and extenders for longer-distance installations.
This section brings together practical product details such as Maximum Video Resolution, HDMI In, HDMI Out, Number of HDMI Inputs, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.
Key Product Advantages
The ST122HD20S distinguishes itself through intelligent EDID management and audio extraction capabilities that go beyond basic signal splitting. The EDID switch offers both automatic scaling and manual copy modes, allowing users to match different display resolutions or maintain consistency across identical monitors. This eliminates common compatibility issues when connecting displays with varying native resolutions.
Advanced Audio Routing
Three simultaneous audio outputs provide unprecedented flexibility for sound system design. Users can send digital audio through HDMI to displays while simultaneously routing analog audio to speakers or amplifiers, or outputting optical audio to home theater systems.
- HDMI audio passthrough
- 3.5mm analog output
- Optical digital output
- Simultaneous multi-format output
Professional-Grade Construction
The metal housing provides superior electromagnetic shielding and thermal management compared to plastic alternatives. This construction ensures stable operation in professional environments where multiple devices may generate interference.
- Metal enclosure
- Enhanced durability
- Better heat dissipation
- Reduced signal interference
Deployment / Use Cases
This HDMI splitter serves numerous professional and commercial applications where duplicate display output is required. In retail environments, it enables synchronized content display on multiple screens for promotional messaging or product demonstrations. Educational institutions benefit from its ability to mirror instructional content from a single source to multiple classroom displays without requiring complex configuration.
For corporate settings, the device facilitates presentation sharing across conference room displays while maintaining audio synchronization. Home entertainment systems utilize the audio extraction capabilities to feed sound to separate audio systems while video displays on televisions and projectors. The compatibility with HDMI/DVI connections through adapters expands its utility to legacy display equipment.
Digital Signage Solutions
Ideal for driving multiple displays from a single media player in lobby areas, retail stores, or transportation hubs. The EDID management ensures consistent image quality across different display models and sizes.
Training & Education Environments
Enables instructors to share content simultaneously with main displays and student monitors. The audio extraction allows separate amplification for larger rooms while maintaining video synchronization.
Physical Profile
The compact black metal enclosure measures 4.72 inches in length, 2.48 inches in width, and just 0.43 inches in height, creating a low-profile form factor that fits discreetly in AV racks, behind displays, or on desktop setups. The metal construction not only provides durability but also aids in heat dissipation during continuous operation. The small footprint makes it ideal for installations where space is limited, while the universal power adapter eliminates the need for region-specific power bricks.

FAQ
What maximum resolution does this HDMI splitter support?
The StarTech.com ST122HD20S supports Ultra HD 4K resolution at 3840 × 2160 pixels with a 60Hz refresh rate. It utilizes HDMI 2.0b specification with 18Gbps bandwidth to ensure smooth transmission of high-resolution content without compression artifacts, maintaining image quality across both output displays.
How many audio output options does this splitter provide?
This HDMI splitter offers three simultaneous audio output options: standard HDMI audio passthrough to displays, a 3.5mm analog audio jack for connecting to speakers or amplifiers, and an optical digital audio port for home theater systems. The built-in Digital-to-Analog Converter enables audio extraction and format conversion without additional equipment.
What is EDID management and how does it work with this device?
EDID (Extended Display Identification Data) management allows the splitter to communicate with connected displays to determine their capabilities. The ST122HD20S offers two modes: EDID Auto uses the built-in scaler to match different display resolutions automatically, while EDID Copy replicates settings from the first output to ensure identical configuration across multiple displays starting from 720p resolution.
What is the maximum cable distance for reliable operation?
With standard passive HDMI cables, this splitter maintains reliable signal transmission up to 16.4 feet (5 meters).
