DisplayPort display emulator EDID emulator Plug, Headless 2560x1600@60Hz-6P

On work from home days, we connect to the office pc using Splashtop remote connection. This is like an exact video feed of my office pc. Sadly my work pc only has one monitor, but I have two monitors at home. This little device tricks my office pc into thinking it had two screens. So when I connect from home, I can use both of my monitors!The device is plug and play, it appears as a monitor option. It is very niche, but it's great this exists. It is just a simple HDMI plug connected to a few resistors, so you could totally bodge one together if you had an old HDMI cable and a few components. However this is only 4 pounds and it just works.

If you're trying to fool a GPU... or in my case using a broken screen laptop for remote connections. This works wonders. it's just plug and play, no drivers or anything like that.a 1080P display is detected straight away, no compliants, works perfectly.

I brought this to add a loopback display to my PC so I could connect to it with Parsec. Worked right away and flawlessly.

This little device saved me no small amount of frustration with a lagging mouse cursor and keyboard when connecting to a remote PC.I'm a Linux noob but decided to install it on a spare PC that was going to run as a networked device without a monitor, using TeamViewer to access the desktop as required. After installing the OS and setting-up TeamViewer, it was working perfectly until the moment I decided to remove the monitor and move the Linux PC to its proper location. Upon rebooting, TeamViewer lagged awfully - both mouse and keyboard.Google was full of answers, but none worked for me.By chance, I came across a post saying that the problem could be occurring because there was no monitor attached to the remote PC, what with TeamViewer requiring some form of output from the graphic card to work properly.I saw this virtual display adaptor on Amazon and thought that I would give it a go. It worked perfectly! Very much worth the small price I paid.

Plugged it into my headless PC, no virtual monitor found, which is what I was expecting.

For those of you not familiar with exactly what this is, this basically fools your PC or GPU that a monitor is plugged in when it isn’t. Now why would anyone want to do that? Well… my home theatre PC would outright not boot plugged into my TV (kinda important) but confusingly worked perfectly when I switched to a normal monitor using DVI or Display port or EVEN… HDMI, tested the cable, seems fine a laptop displays no problem… so after consulting with friends that know more about HTPC setups they suggested it may have been an AMD driver update that’s screwed up the handshake bit of HDCP (the encryption the HDMI uses, cheers Sony) why this stops a PC from booting is beyond me. However, it was detecting this what I am calling a HDMI butt plug as the primary display (TV was blank). I had to remote to the PC and set it to clone the output to the TV and hay presto I can see my HTPC again without the nonsense of the mouse randomly disappearing off one side. Also when remoting to this PC it means it will ALWAYS now be 1080p instead of reverting to a lower resolution good for if this is being used on a remote server I suppose. PS, Dear AMD\Sony I should not have to BUY one of these!

I have a headless plex server in the loft, windows requires hdmi in so I can log in via a vnc to view it. There's no point of keeping a monitor plugged in and keeping it turned on if I'm not using it. This does the job for me. Tricks windows into thinking there's a monitor. Only a fiver, use it all the time. Excellent piece of kit.

installed a discrete gpu into my headless server box, this then upset windows and i was unable to access deskptop via teamviewer. Internet forum suggested a dummy HDMI plug, which i found here and voila it works.
