4K 120Hz HDMI 2.1 Dummy Plug,Virtual Display Emulator,Headless Ghost Display Adapter Support 3840x2160@120HZ,1440@120HZ,1080P@120HZ EDID Monitor Emulator（8K not Supported）

Works exactly as described by listing. Connected to RTX 3080 Ti, this adapter enables a host of 120hz streaming resolutions with no additional configuration. I've successfully used 1080p, 1440p, 1600p, and 2160p all at 120hz. Perfect for Parsec and Moonlight with M2 Macbook Pro.Only disappointing thing is that HDR is not supported by default. This may be possible to enable with a utility, but I have yet to try.

Just works, no software installs needed. Using Windows 11.

I have been seeing EDID issues between my Denon AVR and Hisense C2 Ultra projector. The connection works initially, but intermittently the screen will blank out for a second before the connection startes working again.This device did not resolve the issue. In fact with this device added to the connection the connection does not work at all.Will be sending this back.

So I got this to work for Moonlight purposes and another user review did a good job of spelling it out. I did manage to enable HDR through Custom Resolution Utility (CRU) and EDWriter. However, I couldn't enable it without using a DP 1.4 to HDMI 2.1 adapter (I used the Cable Matters version if it matters).A small tutorial without needing to use a 4k120hz HDR TV to dump settings would go as follows (screenshots included).0) Acquire CRU and EDIDWriter. ToastyX is the author of both and are easily located through google.1) With the dummy plug connected to a HDMI 2.1 port, fire up CRU and make sure the dummy plug is selected (LL2160 - WOIEYEK 4K120 for me).2) Under extension blocks, select "CTA-861..." and click the edit button below that.3) Under Data blocks, you will have to add "Colorimetry" and select "BT.2020 RGB" and "DCI-P3", click "OK" to save and exit the Colorimetry menu.4) Back under the Data blocks section, you will next edit "HDR static metadata", within that make sure the "Traditional Gamma - HDR" is ticked on under the Transfer Functions group. Click OK to save and exit that view. Click OK in the Extension block menu to return to the main view of CRU.5) In the bottom left, select "Export" and give this EDID profile a name. I used "Woieyek4K120HDR.bin" for mine. Once the file is saved to a known location, you can exit out of CRU.6) Open up EDWriter and make sure the dummy plug is selected (LL2160 - WOIEYEK 4K120 for me).7) First select "Read EDID" and then select "Save file...". This is a backup in case something goes wrong with the dummy plug. I used "Woieyek4K120.bin" as the file name.8) With the backup created we can now flash the dummy plug with the new bin file. First, select "Load File..." and select the modified bin file (Woieyek4K120HDR.bin for me). Once the file is loaded in, you can now click "Write EDID" It will ask if you are sure, and simply confirm that you want to flash it. In the event something goes wrong, you can use your backed-up bin file to flash it back to its original state.9) Now with the DP 1.4 to HDMI 2.1 adapter connect it to another available displayport out on your GPU. Add the dummy plug.10) Restart windows, or restart your video drivers (CRU gives you an exe to do this with restart64.exe)11) Confirm you can achieve 4K 120hz with HDR enabled.Hopefully, this helps! It's made streaming high resolutions to my moonlight devices with high framerates and HDR possible without taking up other active monitors.

I have a rather robust home network and while I enjoy playing on my gaming PC, sometimes I just like to be a couch potato. I couch game with Steam Link on a Samsung S23 Ultra and Gamesir G8. The issue with Steam Link is that it needs a monitor to display the game before streaming it to your device.This dummy plug lets me turn off both of my monitors and stream to my phone without any issues. I never have to worry about screen burn while being a lazy gamer!

10/10, using this in 2 PCs for cloud gaming. LPlug it in, set display to duplicate, and forget about it

Though I bough the 4K HDR model it fails on anything over 1080p. I have tried it on both mac and pc with the same result. The pc does give me 4K as an options for a resolution but the device does not pass the 4K to the monitor, when I remove the device 4K works perfectly.I purchased to stabilize the connection as I switched devices on my KVM but this doesn't work when the device is selected let alone support the KVM switch.

I have a Wacom Cintiq Pro 27 monitor that I use for work. I wanted to use Govee lights to backlight it so when I'm working at night I have a nice ambient matching light setup. Unfortunately, plugging the Cintiq directly into the Govee system didn't work. My brother recommended this dongle, and now it works perfectly!
