I noticed that from firmware 299 on pitool 274 on the 8kx that the HMD is not connecting.
I checked with the technical support team, they reverted to firmware 296 I am able to get the HMD to display just fine on that firmware with pitool 271.
Is there a way to set a main GPU for pitool? I tried 3D settings in Nvidia control panel but they have long since removed the option to set a main GPU for an application.
I have my main displays set to the 3090 and disabled all displays on the 550 even tried unplugging all inputs connected to the 550GPU.
I tried changing the Main GPU in the bios to be slot 1 (3090) and reinstalled pitool and connected the HMD, no dice same issue.
The only way to get firmware 299 working is to either run w10 in a VM and passthrough a 3090 to it, or physically remove the 550 AMD GPU from the second slot.
The only way to get it working bare metal is the latter workaround which is just not practical, there is no way to disable a dedicated GPU in bios, and disabling the second GPU in device manager does nothing.
This used to work fine from firmware 296/ pitool 271 Is it possible for pimax/pitool software devs to fix this issue in a future firmware update?
