GPU hardware is often disabled until a monitor is connected, resulting in poor performance and limited resolution for remote users to work on.3. When the GPU is enabled, various tasks can be performed, including high resolution and refresh rate enabling hardware to accelerate GPGPU operations such as remote desktop and cryptocurrency mining, and the resolution supports 800x600@60/120HZ-3840x2160@60/120HZ.How can it help you?1. Solve the problem of black screen/white screen/low resolution when the remote desktop has no monitor.2. Solve the problem that the graphics card stops working for no reason when mining.3.

Review: Works Great - Works as advertise. Lets you operate your laptop in clamshell mode.
Review: 4k120hz HDR works, but with an adapter and some work. - 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.

### ⭐ Does not work to resolve EDID issue between AV receiver and projector
*by C***G on January 6, 2025*

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.
