IddSampleDriver VS ResolutionAutomation

Get a dummy plug and mirror your monitor to it, or use this https://github.com/ge9/IddSampleDriver essentially the same thing but on a software level.

Indirect Display Driver

This is the way to go. In addition, you can setup a virtual display (I'm using [this](https://github.com/ge9/IddSampleDriver)) so you don't even need a monitor plugged in.

Honestly I'd reccomend moonlight with sunshine - although I can't say I've tested more than nvenc myself - it supports multiple encoders beyond nvec, and has a lot more performance tuning options ideal for a high bandwidth connection like a virtual bridge (which parsec is a bit less optimized for, and looks a bit blockier). It also doesn't need an online authentication, but still needs a dummy plug or this black magic

What is your host system? Since ESXI recognizes it and you could enable pass through without issue I’m thinking it is not BIOS related. I previously had issues with a different GPU on ESXI and it was immediately apparent something was wrong when you went to enable pass through (the checkboxes in the panel would go crazy, turned out to be a GPU map issue in ESXI). As for the display, it shouldn’t be necessary considering in its default state the M40 is intended for compute / CUDA tasks. Eventually you will need a display obviously, but out of the box if you’re just trying to confirm the GPU has loaded without issue a display is not necessary. For the display driver, I’m using IddSampleDriver, which works well (no HDR support, fyi)

this theoretically should work too, tho I haven't yet gotten around to trying

I use this plugin for sunshine and it changes resolution back and forth as needed.

ResolutionAutomation Requirements Change the Sunshine "General" config logging level to "Debug" (enables ResolutionAutomation to read the connecting device's resolution) Open the directory "Windows/Temp" once from File Explorer, which prompts you to permanently allow the user access to the folder. Download and extract the .zip, move the ResolutionMatcher folder somewhere permanent, and ran the Install.bat script

Combined with Monitor Swap Automation and Resolution Automation

Set up this Sunshine utility to automatically manage resolution of the host machine to match the SD (and revert back to default when not streaming). NOTE: I originally found this in this post which also mentions 2 other tools to toggle HDR and swap your primary monitor. I didn't have a need for these but definitely check those out (especially the primary monitor utility) if you're having issues or want to take advantage of that functionality.

you should probably look at these tools, they make life a lot easier using sunshine and moonlight https://github.com/Nonary/ResolutionAutomation This is to automate the resolution of the stream and make it match that of the device you use

Here you go
