Dummy Plug fit-Headless Display Emulator 10 Packs DDC EDID Headless Ghos with Windows Mac OSX Linux High Resolution Virtual Monitor Display Adapter HDMI-Compatible 1920x1080@60Hz(2K-10P)

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.

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!

I have this for a headless server I run at home for PLEX that I want to remote into with Anydesk. All I had to do was plug it into a HDMI slot and worked immediately without any hassle. I have not ran into an issue with it as of yet and love it 😁 Easy to plug in with no setup or hassle.

I was trying to run a headless Windows 10 PC with a RTX 3070 (long story.) Using Remote Utilities to access it was giving me all kinds of weird behavior with Windows that went away if I connected a monitor. So I looked around and came across this dummy display gizmo and it solved my problems instantly. Just plug it in to your video card and you're done. Couldn't be easier.

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.

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.

Until you find out the problem you're having having a solution so simple

I bought this to connect to a Windows PC at work that I have tucked away in the corner of my office ever since switching to a MBP.Has only been a week but zero issues connecting via chrome remote desktop and parsec so far, completely plug and play. I'll update if I run into issues.

It does what it says it do... unlike a lot of less expensive electronics you may find here.

I use these with headless installs of Windows PC's. Helps with chipsets that can have issues booting without an attached monitor, or to present a 1080 screen size when using remote support software.

Funciona sin problemas, una vez puesto sobre el equipo funciona como si hubiera un monitor conectado permitiendo el acceso remoto al ordenador. Perfecto.

***4K 120HZ HDR POSSIBLE WITH TWEAKING THE EDID & HDMI TO DP ADAPTOR***So first of all, you can write EDID to this, which you must do to get the HDR aspect working.Out of the box, it works as 4K or 1440p 120Hz, but no HDR support.However, you can get HDR working on this with 4K or 1440p at 120hz.Via Windows, here at my steps:1. Dumped my TV EDID using CRU (Custom Resolution Utility). FYI my TV is 144hz HDR/VRR capable.2. Wrote the dumped EDID from my TV onto the HDMI dummy using EDWriter-beta2 (make sure you're writing to the HDMI dummy and not to your TV!!!!).3. Buy ASIN B0B2ZF95KC which is a specific HDMI to Display Port Conversion Adaptor*.4. Then connect the the HDMI dummy to the HDMI port on the adaptor and the DisplayPort connector into your DisplayPort on your PC GPU5. Now Windows will allow 4K or 1440p 120hz WITH HDR Working!! Also gsync/freesync compatible*The ASIN product I referenced is a product called:YIWENTEC DisplayPort 1.4 to HDMI 2.1 Ultra HD 8K Male to Female Cable 0.25m Converter 8K@60Hz 4K@120Hz Directional Compatible with DisplayPort PC and HDMI Displays Tvs4/5 stars as annoying it doesn't support HDR out of the box. But got it working with an adaptor and 10 mins work with the EDID dumping / writing.

J'utilise un PC en tant que serveur Proxmox qui nécessite un écran pour la console locale mais la carte graphique (pas de APU/iGPU sur mon processeur) bloque au démarrage si un écran n'est pas connecté.Aucun option BIOS ne m'a permis de me débloquer de cette situation, et je ne souhaitais pas changer la configuration de Proxmox et perdre ma console locale. J'ai donc choisi d'acheter ce produit pour régler ce problème et cela fonctionne à merveille dans mon cas d'utilisation.
