Your cart is empty. What does Display Emulator / Dummy Plug do?
It fixes a problem you probably didn't even know you had - unlocking the full potential of your graphics card hardware.
By simulating the presence of an attached display, display emulator allows you to use all of the power and available resolutions locked away inside your graphics hardware,which might otherwise be disabled when there is no screen available.
Why do you need a HDMI/DVI/VGA Display Emulator?
HDMI/DVI/VGA Display emulator is a small, low-cost plug that work as a high resolution display, it makes a computer run "headless" (without a keyboard, mouse, and monitor).
It appears as a headless ghost display emulator (dummy plug) that fits discreetly in to the video output socket on your computer.
Once plugged, the headless PC detects a connected display thus enabling the GPU.
Remote desktop access to the headless PC is then available at high resolution - up to 4096x2160 and high frame rate.
With the GPU enabled, it is possible to perform for various tasks including high resolution hardware accelerated remote desktop and GPGPU operations like crypto currency mining, rendering and simulations.
It is a must-have for server and colocation farms, SOHO and home servers and remote-deployed headless PCs.
Resolutions Supported
HDMI dummy plug: Maximum 4096*2160@60Hz;
DVI dummy plug: Maximum 4096*2160@60Hz;
VGA dummy plug: Maximum 1920*1080@60Hz

I use a number of computers headless using VNC. these dummy displays allow these computers to be used quite well remotely.

Needed a few DELL towers to boot to NVIDIA cards without monitors. Plug these into card and system boots up fine. Low cost, does exactly what I needed.

仮想PCでGPUパススルーした時の画面表示用に購入しました。4K@60Hzで無事動いています。しかしDP用の4K@60Hz対応ダミープラグってものがないですよね、HDMI用はいっぱいあるのに...。なんでなんでしょう？

I had a lot of trouble trying to get Steam streaming to work without having a monitor attached.Without a monitor attached, every once in a while, the game would actually start properly with sound. But generally it wouldn't, or at I'd have picture but no sound.This little emulator has worked out perfectly. I have my main PC set up to log in automatically and start Steam. When I'm ready to stream a game from my laptop, it's totally ready-to-go. No issues ; full resolution and sound.I ready setting up TeamViewer should work as well; there's some magic there. However, I didn't want to rely on another piece of software. With this adapter, I turn the PC on and it's good-to-go.

I cannot believe that I have been in IT for over 30 years and didn't know that these exist. I was literally thinking one day "I wonder if someone has come up with a dummy HDMI connector that tricks the server into thinking that there is a high-resolution monitor attached for better remote access" Well obviously someone was way ahead of me. These work perfectly and make things much easier for me on some older machines that revert to 640x480 when there is no monitor connected when it boots. Now when I connect with TeamViewer, I get a full range of resolution options to choose from, making remote work SO MUCH EASIER.

This works well with Arduino so that you do not need to have a monitor display attached and it will then allow you to get better resolution by accessing your graphics card. Get better resolution without having a monitor attached. These are nice and small and does not take up a lot of space. Works exactly as advertised.

I use these for a few qemu virtio headless VMs to dummy out a passed-through GPU's video output. They work as advertised, and simulate the EDID of a display connected at up to 4K resolution flawlessly. Simple yet effective, no more dummy monitor needed to get output from my GPU in a VM.
