Four-input 8K switch for multi-source setups

The JTECH-8KSW41AE routes four HDMI sources to one display. It handles 8K at 60 Hz, 4K at 120 Hz and 1080p at 240 Hz with HDR10, HDR10+ and Dolby Vision. Gamers and home-theatre owners can connect consoles, streamers and players without swapping cables.

Simple install; EDID mismatches are the main snag

Connect sources to the four inputs and the display to the single output, then power the unit. Switching works via front button, IR remote or CEC. If a source does not detect the display correctly, use the 15 EDID presets or the bypass mode to force a compatible handshake.

Audio extraction covers soundbars and receivers

Optical and 3.5 mm outputs pull Dolby TrueHD, DTS-HD Master Audio, Dolby Digital and LPCM from the HDMI stream. This drives external audio gear while the video continues to the display. Buyers needing more than four inputs or a second simultaneous video output will need a different solution.

Questions about this item

How can I verify the switch is passing 8K@60Hz correctly after connecting my sources?

Check your display's on-screen information menu to confirm it reports 8K resolution at 60Hz, and ensure HDR10 or Dolby Vision indicators appear when playing compatible content.

What cables and accessories are included in the box versus what I need to provide?

The unit itself is supplied; you must provide four HDMI cables for the inputs, one HDMI cable for the output, and an optical or 3.5mm cable if you plan to use audio extraction.

Which EDID mode should I select for a setup with a PS5 and a Dolby Vision projector?

Use the EDID rotary switch to choose the mode labelled for 8K@60Hz with HDR and Dolby Vision support, then enable CEC on the PS5 so the switch negotiates the correct format automatically.
