Bi-Directional HDMI 2.1 Switch

The Vszerda bi-directional HDMI 2.1 switch operates as a 2-in-1-out switcher or a 1-in-2-out splitter. It connects two source devices to one display or one source to two displays, though only one monitor shows an image at a time. An 8K HDMI cable is included in the package. Gamers and home-theatre users who need flexible signal routing between consoles, PCs and TVs will find it practical.

HDMI 2.1 bandwidth and cable limits

The switch delivers up to 48 Gbps bandwidth and supports resolutions up to 8K at 60 Hz and 4K at 120 Hz. It handles Dolby Vision, HDR10, HDCP 2.2 and 2.3, plus DTS-HD Master Audio and DTS:X audio formats. Connected HDMI cables must not exceed three metres on either side of the unit. If the source cannot supply enough power, a micro-USB power input is available.

Resolution headroom and chip performance

The PI3HDX1221 master chip processes 12,000 operations per second and performs overheat detection 14 times per second for stable long-term operation. The 48 Gbps link comfortably carries 8K 60 Hz or 4K 120 Hz signals, equating to 33.17 million pixels at 7680 by 4320. Demands beyond 8K 60 Hz or cable runs longer than three metres exceed the specified headroom.

Questions about this item

Should I use the 2-in-1-out or 1-in-2-out mode for my setup?

Choose 2-in-1-out to connect two sources like a PS5 and Xbox to one 8K display. Choose 1-in-2-out to send one source to two different monitors, though only one displays at a time.

What does the 48Gbps bandwidth actually deliver on my screen?

It carries up to 8K at 60Hz or 4K at 120Hz with 33.17 million pixels, plus Dolby Vision, HDR10 and HDCP 2.2/2.3 for high-quality video and audio.

How does the HDMI 2.1 interface limit cable length and power needs?

HDMI cables on each side must not exceed 3 metres. If the PI3HDX1221 chip detects insufficient power, connect the micro-USB cable to maintain stable 48Gbps transmission.
