Black Screen when viewing with Oculus

Hi,

On my development PC I have installed both 4.8.3 and 4.9.

On my presentation laptop I have downloaded the latest Oculus runtime drivers, after launching the packaged application and entering ALT + Enter the screen goes black?

I have tried this with 4.8.3 and 4.9 also but the same issue - any help is appreciated.

Thanks

You’ll need to share out more specs to get much help.

I’m personally still working with 6.0.1, Win 8.1, and 4.8.3 and having success.

Thanks for your reply,

I have tried to install 6.0.1 runtime, then reverted back to 4.8.3.

The laptop is an Alienware with NVidia drivers 4.35

The issue (I think) is that the scene does not go fullscreen when Alt+Enter is pressed, I have then tried using the ’ to enter fullscreen and stero on but still to no avail - are looking for any other information?
