Perfect for headless machines!

Reviewed in the United States on December 28, 2023

Size: SingleVerified Purchase

I used this for a laptop, so I could use remote desktop software with it without the device needing to be open. This worked perfectly for that, and allowed me to use every feature of the device remotely by making it think there’s already a display connected. This is NOT a wireless display, or anything like that, it simply tricks your device into thinking there’s a monitor connected. It also has a blue LED which is lit up whenever it is connected and receiving power.

Works as expected.

I had another brand of this type of device, but I misplaced it. I use it on a headless server. It allows for high res remote desktop connections. The light is bright, but it doesn’t bother me since the server is kept in a closet. Works as expected.

Works great. Solved my problem.

I got this because I need to remote into a PC with TightVNC. However, because there was no physical display attached I’d only get a black screen. This solves that problem for me. I never knew such a thing existed and it’s a cheap fix for a niche problem.

Almost Perfect Experience

Reviewed in the United States on November 19, 2021

Size: SingleVerified Purchase

I really wanted to give this five stars, but reviews should be honest. I docked one star because the first unit I received was not recognized by any system, so I returned it for a replacement.

Like many others, I’m using the dummy plug to keep the GPU active on a headless system so it doesn’t act funny when I connect to it via remote desktop, and to keep its GPU active for video transcoding. The EDID emulator offers plenty of resolutions and modes, including 1080p 120Hz and 2160p (4K) 60Hz. I set my system to 1080p 24Hz because (1) 30Hz for some reason is not available, and (2) it’s headless and in theory the lower frequency will provide a more stable remote connection over the internet with higher latency.

Basically, this device does exactly what we expect of it, but I have small concerns over reliability and longevity. If I remember later down to the road, I’d probably be willing to upgrade my rating to 5 stars.

Works well for my headless nuc

Reviewed in the United States on January 7, 2024

Size: SingleVerified Purchase

My intel NUC would not stay on unless a monitor was connected. This did the trick. Been running for months now without issue.

Great with Sunshine/Moonlight

Reviewed in the United States on January 10, 2024

Size: 2 PackVerified Purchase

I used Sunshine, an open source version of the Nvidia streaming software to stream games to other systems. I had a problem where Sunshine would choose the wrong output resolution when the system was connected to multiple monitors. Now Sunshine chooses this device and everything is good.

Not detected as a display by Windows on a Dell Laptop

Reviewed in the United States on September 3, 2023

Size: 2 PackVerified Purchase

Windows 11 on a Dell Vostro laptop does not detect this as a display when plugged in to the HDMI port.
I need a dummy display so that TeamViewer can connect remotely when the laptop’s lid is closed.
With this plugged in and the lid open windows says it sees only one display, but if I plug in a “real” display it sees both displays.
I suppose there’s a chance I misunderstood what this device is supposed to do, but I don’t think so.

Light to bright just put electrical tape over.

Reviewed in the United States on October 2, 2023

Size: SingleVerified Purchase

This work for me I use it to make a TV immersion LED light controller to work because I bypassed it with a splitter The unit would not work as intended to. After splitting it the unit would not work until I had an HDMI hooked up on the output that usually goes to a TV so it tricked the controller to think that it had been hooked up to a TV to allow the lights to work behind my TV with this 4K dummy plug. I could have plugged an HDMI cable into my soundbar to allow the device to work but I didn’t want my immersion light kit that I purchased to screw up anything in my soundbar because I had it to an older TV Roku TCL and weird things were happening like the main screen just going on a quarter of the TV screen. But as for this dummy plug it work for me great The only thing I would complain is that the light is a little bright that other people have mentioned so I just put a piece of black electrical tape over it you could always pull it up to see if it’s still lit if you need to.It completes HDCP handshake.Hope I’ve helped

El producto se anuncia como si soportara 1080p a 120hz lo cual NO ES CIERTO.

Lo compré para usarlo como dummy en mi PC con una RTX 4090 y transmitir mis juegos a mi ROG Ally con Sunshine/Moonlight y lo máximo que soporta son 75hz

Lo voy a regresar

I bought this device so I can plug in my pc and turn my main screen ( oled ) off and still be able to make Moonlight ( gaming stream service ) work.

Its flawless for now, I can be about anywhere, just need to have a good wifi and I play all game on my Rog ally at ultra settings 60/120fps ( depends on the wifi ) at 10W for longer battery life !

Great for using headless or even when monitor is off

Reviewed in Australia on August 19, 2020

Size: 3 PackVerified Purchase

Does exactly what it says. I have this plugged into a spare HDMI port on my desktop’s RTX 2080 Super GPU so that I can stream games locally to my NVIDIA Shield TV at 1080p/120Hz with my computer monitor turned off, without any problems. Previously I would have to leave my monitor turned on in order to stream to my NVIDIA Shield, otherwise I couldn’t change display resolutions.

The perfect solution for remote control of closed servers

Reviewed in Canada on March 26, 2019

Size: 3 PackVerified Purchase

I have remote Windows10/Apache servers running on Lenovo laptops that I access remotely using Radmin (excellent product). Ideally, the remote servers operate with no local human interface, sitting on shelves with the screen lid closed. The problem is that Radmin will not work when the screen is closed. Changing settinsg to “do nothing” when the lid is closed does not solve the problem. More drastic registry changes did nothing. But just plugging in the low-cost HDMI Dummy plug into the HDMI port of the remote server instantly solves the problem. The plug tricks the O/S into thinking there is a display attached, even though the display in the closed lid is disabled. And no need for any changes to settings or registry. A perfect product for the job.
