[flashing grey screen]

I keep having instant grey screens. Especially when a scenario such as "crouch and turn your head".

 

The grey screen doesn't happen when the headset gets overheated it starts at the beginning of the steam vr Home / Lobby . There is no vibration on the base stations (checked and double checked). The Vive camera is off. There is no bottleneck on the GPU or CPU

 

I have set up station with dimensions 2.4x2.4 (5.76 m2).

The base stations are set up to the corners of the room

The base stations are mounted with a angle of 40 degrees.

The base stations are mounted at a height of 2 m.

The base stations are connected with the sync cable. (Mode A and Mode B).

The data cable is connected to the usb 2.0 port

 

I have 3 more set ups with the same specs with no problem at all.

 

What i have tried and failed.

changing the usb ports to 3.0

changing the base stations with brand new ones.

changing the cable with a brand new one.

changing headset with a brand new one

covering all reflective surfaces.

changing the pc with a non problematic stations pc.

changing the height of the base stations.

not using the sync cables.

 

Anyone got an idea or a known fix for this issue
