Oh, hey! Appreciate the reply. I don't have any other VR Capable PCs. What I suspect is it's maybe in how the GPU handles the different video outputs. It's likely something that could only be resolved with either : gpu firmware update, BIOS update, (unlikely) driver update. I don't think I will ever have a solution to this issue. I was more so posting to vent//make anyone else in a similar situation aware to a potential workaround. If I ever solve the issue I will be sure to share the research & findings.

Title is exactly my problem... But let me explain. I got a brand new Vive Pro with the base stations, controllers, tracker 3.0. My current system for VR is an MSI GP66 Laptop that has an RTX3070 MaxP (MUX Switch enabled), but the issue is it only has MiniDP & HDMI outputs. Therefore the HTC provided MiniDP to DP cable is not suitable for me. I did some research and as mentioned by user "HackPerception" here : https://forum.vive.com/topic/7268-where-do-i-get-mini-display-port-to-mini-display-port-cables/ I purchased (a considerably expensive) cable : https://www.amazon.ca/Cable-Matters-Mini-DisplayPort-Black/dp/B00ESM3DKA?th=1 that was confirmed to work with the headset. Prior to my getting my Vive Pro I was using a Quest 2 with absolutely 0 issues. I never had any HMD connection issues. For some reason, I can not use my Vive Pro headset as it will constantly lose connection and give an error "Your GPU is having trouble communicating with your HMD resulting in an HDPC error". After hours or trial and error, the solution is to connecting my Vive and get it all setup (turn on the breaker box, plug everything in), then reboot my laptop with everything on, and suddenly it works perfectly. But this will only last until I turn off the breaker box and disconnect the headset. Even Exiting VR, it works perfectly again (without restart) so long as I do not disconnect any cables or turn off the breaker box... I have updated the headset drivers/firmware, running the latest Nvidia drivers as verified in GeForce Experience. And I will re-iterate that I am running in dGPU only mode, the iGPU is disabled via the MUX switch in MSI Control Panel. This is really annoying, and honestly sad coming from a product costing DOUBLE what the Quest 2 costs...
