1x4 8K HDMI Splitter for Multi-Display Setups

This J-Tech Digital JTECH-8KSP14E splitter takes one HDMI source and mirrors it to four displays simultaneously. It suits home theatres, gaming rigs or digital-signage installations where identical content is needed on every screen. The unit handles HDMI 2.1 bandwidth and HDCP 2.3 protection without signal degradation. Plug-and-play operation means no software configuration is required.

Replaces Basic 4K Splitters When 8K

Older 1x4 splitters limited to 4K@60Hz cannot pass 8K@60Hz, 4K@120Hz or 1080P@240Hz signals this model supports. The upgrade is worthwhile when source devices and displays use HDMI 2.1 and demand full bandwidth for HDR, HDR10+ or Dolby Vision content. DSC pass-through preserves compressed high-bitrate video that simpler splitters would discard.

Drives Four 8K@60Hz or Mixed-Resolution Displays

Each output delivers up to 8K@60Hz, while the built-in downscaling mode lets an 8K source feed 4K or 1080P screens alongside native 8K panels. Three EDID modes — Auto, Copy and Downscale — resolve handshake mismatches across different display types. Audio passes through uncompressed LPCM and advanced formats including DTS-HD Master Audio and Dolby TrueHD.

Questions about this item

How much rack or shelf depth does the JTECH-8KSP14E need for cable clearance behind the four HDMI outputs?

The unit has four HDMI outputs on the rear panel; allow at least 10 cm behind it for standard cable bend radius and connector strain relief.

Which EDID mode should I select first when the source and displays report different maximum resolutions?

Press the EDID button to cycle to Downscale mode; the splitter will then negotiate 8K from the source and downscale to 4K or 1080P for each display automatically.

When the HDCP handshake fails on one of the four outputs, which component typically needs replacement?

A single faulty HDMI cable or a display with an outdated HDCP 2.3 implementation is the usual cause; swap the cable or test the display on a direct source first.
