4K HDMI edid Emulator passthrough -Default Resolution 1920x1080@60Hz Highest 3840x2160@60Hz - for Mac Thunderbolt to HDMI Switches/Extender/AV Receiver/Video Splitters

Exact solution for my mismatched EDID handshake between a 4K 120Hz monitor and a mini-PC. The problem requires multiple soft-power down and up to get them connected and work for every cold boot. This $9 solution solves it cold. Expensive cable won't do it. Expensive adapter/converter won't work. Plug this device into the monitor HDMI input then connect it to the mini-PC and it works 100% of the time, cold boot or not. The pc always sees the monitor even when the monitor is not yet ready. One user complained that the device gets hot. Mine stays cool to touch even with all day use. I suggest that you ask for an exchange if yours gets hot. Excellent device for the purpose. Highly recommended.

KVM i have when switch computer and back to first one there was nothing and had to reboot the computer every time ... by putting this resolve the issue , now back forth switching my monitors stay connected . edid Emulator help fixing the issue

Al principio creí que el problema era del puerto HDMI de mi laptop, pero resulto que las pantallas y proyectores al que lo conecto son muy viejos, ahora con este adaptador puedo ir con seguridad que el problema son los demás

I was getting so frustrated with Windows' handling of what it thinks is a new device (a TV I plugged in) forcing a re-acquisition of EDIDs and triggering two of my main screens to go black and refresh. I tried a powered HDMI hub but it lacked EDID capability and the problem persisted. This little interstitial device is more compact than the hub, doesn't require external power, and works perfectly to keep the fourth display I'm using known to Windows and preventing screen refreshes (which were particularly annoying when gaming). Exactly what I needed to solve that problem, worked flawlessly with no additional setup required.

Works as an edid emulator, but as the emulated resolution is not exactly 4k60 (it's 4k61hz) you can't use it as a pass-through on any device that doesn't let you change refresh rate
