SHERRIVA 4K HDMI Splitter 1-in-2 Mirror — HDMI 2.0 4K@60Hz, 18Gbps, Auto Downscaling

The SHERRIVA 4K HDMI Splitter 1 in 2 out duplicates one HDMI source to two displays with HDMI 2.0 performance, supporting up to 4K@60Hz and 1080p@240Hz for mirrored video and audio.

Designed for setups that need the same picture on two screens, this mirror-only HDMI splitter sends identical audio/video from a single source to two displays simultaneously. It supports HDR formats, HDCP 2.2, and an 18Gbps data lane to preserve color depth and frame rates where supported. Automatic EDID detection and smart power management help reduce compatibility problems so you can connect consoles, streaming boxes, or PCs with minimal fuss.

How does the splitter handle different display resolutions?

The unit uses EDID detection to negotiate the best common output for both connected screens. If one display cannot accept the source resolution, the splitter will downscale to the highest mutually supported resolution (note: 720p and 480p downscaling is not supported). This prevents black screens and keeps both displays showing the same feed.

• Automatic EDID polling to determine shared resolution
• Auto downscaling to compatible resolutions supported by both displays
• Does not support extended desktop mode — mirror only
• Maintains audio pass-through for connected displays

Will it work with modern gaming consoles and high-frame-rate content?

Yes — the splitter supports 4K@60Hz for high-resolution content and up to 1080p@240Hz for high-frame-rate feeds, which accommodates many gaming use cases. It preserves HDR metadata and is compatible with popular consoles like PS5, Xbox, and Nintendo Switch, although it is not intended for systems requiring eARC features.

• Supports HDR, Dolby Vision, and Atmos-compatible audio passthrough
• 18Gbps bandwidth to sustain 4K@60Hz video streams
• Compatible with PS5, Xbox, Nintendo Switch, streaming devices, and PCs
• Not compatible with eARC systems or audio-return features

How does power and connectivity behavior affect installation?

The SHERRIVA splitter includes a 5V DC power adapter and implements smart power detection to ensure stable signal transmission. It requires external power for proper operation; without the included adapter some displays may not be recognized reliably. Simple LED indicators and labeled HDMI ports make it straightforward to set up in a living room, conference room, or gaming station.

• Includes DC 5V adapter for stable operation
• Smart power detection reduces connection errors and black screens
• Plug-and-play design — no drivers needed
• Compact housing fits near TVs, monitors, or AV racks

What limitations should buyers be aware of?

This device mirrors the same output to both displays and does not support extended desktop modes or independent screens. Some legacy displays or very old cables may limit achievable resolution or color depth. Also, while it supports modern HDR and HDCP 2.2 protected content, it won’t pass eARC audio return signals.

• Mirror-only output; no extended desktop capability
• 720p and 480p downscaling not supported by design
• Not suitable as an eARC audio solution
• Performance depends on HDMI cables and display capabilities

Who is this for: The SHERRIVA 4K HDMI Splitter is aimed at homeowners, streamers, educators, and small business operators who need identical high-quality video and audio on two screens — for mirrored TV setups, dual-monitor signage, demo stations, or simultaneous viewing of gaming consoles. If you need duplicate displays with minimal configuration and strong compatibility with modern 4K/HDR sources, this unit offers a compact, straightforward solution.
