Error 400 (Compositor not available) - Symptoms and Solutions


Recommended Posts

  • 2 months later...

None of the steps in this thread have worked for me. It's getting pretty frustrating, especially because this isn't a cheap purchase. If there are no fixes for this, it'll be an easy reason for me to preach to people to NOT purchase this product, unless you want to throw away close to a grand.

I appreciate that it's frustrating.  Every set up is unique, are you asking for assistance?

Please tell me more about your set up (OS etc.)

Can you also double check and confirm whether the Vive is being detected as a monitor? Right click desktop-->display settings.

Keep receiving error 400 when trying to setup my htc vive
I have an Asus Gaming laptop with NVidia GeForce GTX 1050ti graphics card,. I have updated my drives, tried rebooting , unplugging and trying different usb ports, tried using a mini display port instead of hdmi because my laptop has 1 hdmi port but nothing is working and I keep receiving same error code. I need help thanks!

It isn't just under the minimum requirements, it's significantly under the minimum requirements. In a very broad sense, the GTX 570 is less than half as capable as the GTX 1060, which is our minimum recommended GPU for Vive.

Even if you solve Error 400, the games will be unplayable.

Thank you,
