Launch Steam VR witout monitor : famous error 400, compositor failed

[StuntmanMike]

Hello,

For an app, i use the MSI VR One and, off course, i don't want to connect a another monitor (we control the app with network commands). With a monitor : work fine, without : Compositor error (400), each time...

I try all the "classics tips" (driver update / cables / install Steam VR etc.), but nothing work !

Somebody try to use the same configuration ?

 

Thanks !
