I purchased this to run AppleTV headless. The product works well and as expected but to access AppleTV over the local network requires specific certain steps.My Configuration:HDMI dummy plug purchased on Amazon: FUERAN 4K-1080@60-3840x2160@60 HDRApple TV model: 4K 32GB A1842AppleTV selected as HomeKit preferred Home Hub in Home app , normally runs with wired ethernet connection.Steps to access AppleTV from Macbook when headless:1. With AppleTV connected to a TV, configure AppleTV settings to use your WiFi and confirm wireless network connection.2. Insert HDMI dummy plug into AppleTV HDMI port (instead of HDMI cable going to TV).3. Unplug ethernet cable from Apple TV, which will then force it to join your WiFi. Leaving ethernet cable plugged in will not allow this to work via a Macbook laptop (surprising and don’t know why this is the case).4. Make sure Macbook laptop is connected to the same WiFi network as AppleTV.5. Wake up AppleTV by pressing home button on AppleTV remote.6. Start Quicktime on laptop, cancel file open dialog box, then from the menu select "File / New Movie".7. In QuickTime at bottom of screen select "Screen" as “Apple TV”.8. Use AppleTV remote to navigate while viewing laptop screen.9. If no AppleTV screen appears in QuickTime, try rebooting Apple TV by unplugging power.10. When finished using AppleTV via Macbook, plug ethernet cable back in to AppleTV.

Works exactly how I needed it to! I am using these for Intel NUC mini PC. My Team Viewer now allows me to change a huge range of resolutions to get the best sized screen when viewing remote.Value for money is great as long as they don’t fail or have some glitches.

Product work as intended especially with the HDR. I was also able to create custom resolution for my Microsoft Surface Products using aspect ratio of 3:2 and my iphone. I havent tested it with my Playstation but i am assuing it should work with ps5 to enable vrr and HDR and stream my ps5 using my laptop that does support HDR

Works great. 4k hdr dummy plug. I use it for game streaming to my tv and am able to mirror my tv's specs.

It does what it's supposed to do. Great item.

I have a recently purchase Beelink EQR6 Mini PC running Win 11 Pro that I run "Headless". No monitor.). (Works wonderfully well.)I wanted to configure things so that I might access it locally (on the same network) as well as from across the country.I chose to use Chrome's remote desktop app for that purpose.Chrome's Remote Desktop app worked fine but the display resolution that I saw after connecting to my Beelink EQR6 Mini PC was 640 X 480.Folks on the Internet told me I was seeing this resolution because the Beelink EQR6 Mini PC didn't have a physical monitor installed. And these same folks recommended I buy and install a "Display emulator plug".I chose this one from Amazon.Once plugged into one of my Beelink EQR6 Mini PC's HDMI connectors, I I tried a Google Remote Desktop connected and the resolution was 1920 X 1080.I didn't need to make any changes to the Beelink EQR6 Mini PC or restart it after inserting the "Display emulator plug". Was absolutely Plug and Play.I have only had this "Display emulator plug" for 3 hours but so far, I would recommend it.

Nice and small. Allows you to restrict video transcodes to the onboard display adapter. Without a monitor detected, transcoding is usually disabled. This device allows you to take advantage of Quick Sync with your Intel UHD 630 or 750 IGP for a better end result with lower power usage. Your discrete display adapter is freed up for gaming or design. My UHD630 and i7-9700K with 32 gigs of RAM exceed the transcoding capacity of my Radeon RX580.Plug in and reboot. In Windows, go to Settings > Display. Set Multiple Displays to to "only show on 1/2". Now click Graphics. Find your transcoding applications either on the list or by adding a "classic" or "desktop" app and browsing to its .exe file. In the case of Plex, you will want both Plex Media Server.exe and Plex Transcoder.exe. Depending on your operating system, select the "power saving" designation or the specific display adapter. Fire up a transcode and watch the activity in Task Manager > Performance to confirm.

1 of 3 was DOA - Functionsl ones did their job.Title pretty much says it all. Worked great for remote access where "physical screens" need to be present.
