Split 4K sources to two displays

This HDMI 2.0b splitter takes one input and sends identical 4K2K@60Hz signals to two outputs. It handles 18Gbps bandwidth with built-in equalisation and retiming for clean transmission. The unit suits conference rooms, classrooms, digital signage and residential installs where the same content must appear on two screens simultaneously.

HDMI 2.0b bandwidth and EDID limits

The splitter passes 4K2K@60Hz at 24bit RGB/YCBCR 4:4:4 and supports LPCM 7.1CH, Dolby TrueHD and DTS-HD Master Audio. HDCP 2.2 compliance protects premium content. VESA formats up to QSXGA@60Hz are accepted. Smart EDID offers a fixed 1080p mode or copies the EDID from output one so both displays receive a compatible signal.

Check source resolution and cable reach

Verify your source can output 4K2K@60Hz or the lower resolution you need, and that both displays accept that timing. Ensure HDMI cables are rated for 18Gbps over the required lengths to avoid signal loss. The fixed 1080p EDID mode helps when one display cannot handle 4K, but both outputs will then show 1080p. No downscaling is performed.

Questions about this item

Should I pick the 1080p STD mode or the TV copy mode for my two displays?

Use STD mode when both screens are 1080p; use TV mode to copy the EDID from output 1 so the source matches that display's capabilities.

What does the 18Gbps bandwidth actually deliver on a 4K screen?

It carries 4K at 60Hz with 24-bit RGB or YCbCr 4:4:4, plus LPCM 7.1CH, Dolby TrueHD and DTS-HD Master Audio without compression.

How does the HDMI 2.0b and HDCP 2.2 interface limit what I can send?

The 2.0b link caps video at 4K 60Hz 4:4:4 and 18Gbps total; HDCP 2.2 protects premium 4K streams, so older 1.x sinks may fall back to 1080p.
