HDMI Dummy Plug 4K@60Hz 2K@120Hz 1080P@144Hz, Virtual Monitor Emulator, Headless Display Adapter, EDID Emulator, Supports for Windows, Mac, Linux – Plug & Play （Golden 4K60Hz 1Pack）

Works like a charm. Plugs into an HDMI port and reports a slew of display resolutions that you can set in order to change display resolution while using remote desktop software. On my Mac, the dongle reported 30 display resolutions ranging from 4096x2160 (4k) to 800x600 (SVGA). Most common aspect ratios are covered (1.9:1, 16:9, 16:10, 4:3). There are no UltraWide aspect ratios or "tall" aspect ratios (like 3:2 on the HP Spectre x360 13.5).

Works like a charm. I needed something to fool my remote desktop software into thinking there was a monitor attached, and this worked. Been working all afternoon and no issues so far.

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.

Sometimes you just need a GUI on a headless server. This lets me use remote desktop programs to interface with my remote server.

Worked perfectly! Contains a flashable EEPROM. I was able to generate a custom EDID with timings/resolution for my ipad screen and flash it back to the dongle. Now I can use it an additional monitor with the native resolution.

Cheap and easy to use. This is what I was looking for when building my server.

Doesn't seen to enable a display using SuperDisplay app. Very disappointed. waste of money

This product works if you have 1920x1080 or less on both ends. Higher resolutions do "work" but I was unable to get a decent display image. Better than nothing, and inexpensive, it will allow a headless server to be accessed with various remote (VNC, RDP) software. Inexpensive too. If you are trying to seamlessly connect to modern Apple computers, you should consider the higher quality and more expensive 8k adapters with a good cable instead. That's what I did. I'll keep this in the drawer as an emergency item.

Emuliert einen 4k Monitor. Falls er eingesteckt wurde bevor der PC gestartet worden ist, im Betrieb nochmal raus und rein.

Small, elegant and works perfectly. When connected, my PC sees it as a 4K monitor. This makes steam streaming sessions work properly with no additional monitors connected. I have wanted to hide my big PC away in the basement with ethernet and no monitor and stream content from it, to create a quiet, serene home office, and this headless ghost lets me do that! Love it.

Não preciso mais de um monitor plugado para ter alta resolução no acesso remoto via TeamViewer. Excelente!!

このタイプの商品は、ダミーとして使えないというものも結構あり（騙されて買っているだけかもしれないけれど）、今回もおっかなびっくりでしたが、今回はバッチリ表示されました。リモートデスクトップとしての使い方をするPCには最適です。
