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

A+. Picked up the 3-pack and couldn't be happier. These HDMI dummy plugs work exactly as advertised — plug them in and your system instantly recognizes a 4K HDR display with zero fuss. No driver installs, no configuration headaches. Great for headless PCs, remote desktop setups, GPU rendering rigs, or anywhere you need a virtual monitor. Having three in the pack is a great value and means you've got spares on hand. Highly recommend to anyone who needs a reliable, no-nonsense headless display solution!

I picked up this 3-pack of HDMI dummy plugs to use for a headless PC and remote access setup, and they work exactly as expected. As soon as I plugged one in, my system detected a display right away, which solved the issue of not getting proper resolution when connecting remotely. No drivers or setup required — just plug it in and it works. The build quality feels solid for such small adapters, and having three in a pack is convenient if you run multiple machines or want backups. They’re especially useful for servers, mining rigs, or remote desktop setups where no physical monitor is attached. I tested these on a couple different devices and had no compatibility issues. Overall, these do exactly what they’re supposed to do and save a lot of hassle if you need a virtual display. Simple, effective, and good value for the price.

Life saver for my raspberry pi 5. I wanted to use it as a remote only web viewer. Without this dummy plug both RealVNC and Pi Connect were absolutely unusable and extremely laggy I plugged this into the Pi 5 and now both remote viewers are working flawlessly with high refresh rates. This is a must have if you want to run a raspberry pi or computer in a headless configuration.

They are inexpensive and work great. They keep the resolution high on my headless Mac mini.

I use this on a mini-pc that I use for a headless server so that Linux desktop will not get confused when I remote in using NoMachine. It works great and is compatible with Linux without needing to do anything but plug it in, no complaints! It supports all the screen resolutions that I would want.

Does not support 1080p. Does not support 4k at 60hz (supports it at 23hz) Tried setting 1080p for my ubuntu machine and it was not working via cvt and xandr. After checking "xrandr --props" in the terminal I saw it definitely does not support 1080p, and the 4k is at 23hz Here is the xandr output: HDMI-0 connected primary 1280x800+0+0 (normal left inverted right x axis y axis) 620mm x 340mm 4096x2160 23.98 + 3840x2160 23.98 1280x800 59.81* 1280x720 60.00 59.94 50.00 1024x768 60.00 800x600 75.00 72.19 60.32 56.25 720x576 50.00 720x480 59.94 640x480 75.00 59.94 59.93

Does exactly what it says. Im using it as a dummy display for a headless machine that I only need to remote into. Does that job perfectly.

Unfortunately, only 2 out of 3 of these dummy plugs worked out of the box. Thankfully, I only needed one for my intended purpose, but anyone who absolutely needs three might consider buying 2 packs, or looking elsewhere. Despite 1 being faulty, these dummy plugs seem to be robustly built (although, full disclosure, I have only been using them for a short time). Windows recognized them right away, without any drivers or applications needing installation. The best thing about them, though, is they can help solve unique and/or complicated PC and A/V connection issues- which is why I needed them. I have knocked off 1 star for the faulty plug but otherwise I would recommend these.

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.

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.
