HDMI Dummy Plug Headless Ghost Display Emulator HDMI-Compatible（Fit Headless-1920x1080 New Generation@60Hz） (HDMI2.0-2K-1P)

Normally these are not worth the money to me, it’s a dummy plug. That said, it’s a super simple way to tell your headless server, or say Mac Mini, to use a static resolution- no need to find a finicky software or compromise your computers security.They are built solid, fit correctly but not too snuggled, have a low profile with enough space to still easily grab and remove, and being hdmi works with any hdmi compatible computer.

These work great and can provide 4k@120hz resolutions. I used these to move the heat generator into another room and remote connect using Moonlight and Sunshine. Only gripe i have is that i cannot get them to allow 1440p ultrawide at anything higher that 60hz.

I was trying to setup a headless sever and the speed and screen quality was terrible over vnc (it was fine when a monitor was plugged in). After doing doing some research it turns out that the client / server was using an internal video card model when the system did not detect a "real" connection.I have used loop back plugs to test networks most of my career and thought that there must be an equivalent to provide a dummy load video tests. So I looked and found this. Shut down the system and put the plug in, rebooted, and connected via vnr. The default screen resolution was defaulting to higher then expected, so changed it down (remotely) and now everything works perfectly!Good product at a great price.

This is brilliant! I have a headless Windows 10 machine sitting in our datacenter. This is my primary machine that I use on a daily basis. On my 1080p laptop, I am able to use Microsoft RDP to terminal in to the machine and everything is fine. My remote session is viewed at 1080p. However, I HATE HATE HATE using the Microsoft RDP client on my phones or tablet. In the past I would use TeamViewer along with AnyDesk to remote in at 1080p. But ever since removing the monitor, I am only able to get a lower resolution on my remote session via TeamViewer and AnyDesk. This led me to do some research and having found these HDMI plugs for headless machines. These would "trick" or emulate a monitor being connected to your session host so that using remote desktop software will also allow you to view the session at a much higher resolution.I'm glad to say that this little guy works perfectly after a reboot! My AMD graphics card "detected" that a monitor was plugged in. My real test was connecting with TeamViewer and AnyDesk. It works! I am also able to select a much higher resolution than 1080p but I havne't tried this since my monitors are sadly still only 1080p.The only question is how long will this little guy, which undoubtedly is made in China, will last. My computer stays on 24/7 so this guy won't get any rest at all.

If you need a dummy plug for whatever reason, these will work.However, if you are like me, you might have purchased these because they say they do 1080p natively... which is true, but because it also goes to 4k, this can be a problem for some situations. In my case, I'm trying to stream my SteamDeck, and my XR1Lite defaults to 4k capture at 30hz. Until Valve lets us define the resolution manually, this means the Deck also will follow this. If I connect a TV on the pass through, then this will set the capture card to report its resolutions (up to 1080p), and thus the deck will follow along.So you can see why I purchased the plug, and specifically these ones that say "will do 1080p natively." As included in the screenshot, they support up to 4096x2160@24Hz. This means the deck will follow along, making things slow. Thankfully, with a Raspberry Pi, I was able to flash one of the plugs to mimic my TV's EDID signals, resulting in it reporting only up to 1920x1080@60Hz. This does require using edid-rw and tvservice to write and dump the edid data, but if you were needing to know, these plugs will accept the new dumps and have worked great as a result!However, if you are wanting an out of the box experience of 1080p only, as it would appear to be listed as, you will be spending a good while getting everything set up just to fix the issue. At least you get 3 of them for experimenting.

They plug right into the HDMI port on the graphics card. A little blue LED lights up to show that the thing is working. No software to configure. Super easy to use!

Using the Plugable Docking Station caused my PC to see a third "Phantom" monitor which caused problems with my screens. This device solved my problem. After installing it, I disabled the "phantom" monitor on my desktop. I no longer get some screens going to the phantom monitor where I can't see them. Plugable support (Michael S.), was very helpful and clued me in on this device to solve my problem.Mark
