3 Pack HDMI Dummy Plug 4K HDR,Virtual Monitor EDID Emulator, Headless Display Adapter,Supports up to 4k@60Hz,1080@120Hz

Lo conectas y listo. Yo los uso para poder conectarme de forma remota por Anydesk a tres equipos con Windows 11 que tengo sin una pantalla.

Used it to make a computer a headless server and it works perfectly. Compatible with older MacOs devices. No lag or issues. For the price, you cannot beat it.

Muy bueno cuando no tienes mas de 1 monitor y quieres grabar tu pantalla y ademas quieres seguir trabajando mientras se graba o simplemente para hacer presentaciones en PPT, funciona muy bien hasta ahora.

This just makes your computer think it has a monitor connected. Most computers need something like this for remote desktop software to work well or at all, and some need it to even boot. They are metal, well built, feel pretty nice. They do the job fine, there's nothing really good or bad to write about them. They just sit in the back of your computer near invisible and work.

I pop into remote computers all the time, for both work and home purposes. I'd been cheaping out by simply proping open laptop lids with a thumb drive to keep the screens on - it was workable, but that is far from ideal. Finally decided to do things "the proper way" and bought an 8-pack of dummy plugs. Stuck one in each of my home devices, and I hate to say it, but these dummy plugs brought me more joy than other more expensive play-toys I received in the same order. They're not big, but I'd love to see something even more smaller. They work very well, too! A little blue light opposite the plug end confirms it is working. Installation was literally plug-and-play on W10 and W11 boxes, so there's your compatibility statement - likely compatible with many other OSs, too. Also can confirm, they are compatible when used with a mini DisplayPort to HDMI adapter, for devices without an HDMI port. 11/10 recommended for people who need to remotely access systems, when those remote systems are headless (no display attached).
