What Exactly is SteamVR Error 475?

Error 475 belongs to a family of SteamVR connection errors (like 108, 208, and 436). Specifically, 475 indicates that SteamVR has lost communication with the headset’s display path. The USB connection may be working (audio and tracking might still function), but the video signal (HDMI or DisplayPort) is not being received.

Common symptoms before the error appears:

• The headset screen remains black or grey.
• The LED light on the headset is red or blinking green.
• SteamVR shows the headset icon with a red exclamation mark.
• The base stations and controllers track, but the headset doesn’t display anything.

Common Causes

Several issues can trigger this error:

1. Graphics Driver Crashes or Hang-ups: The most common cause. The GPU stopped responding, so the compositor lost its connection.
2. Overlays and Conflicting Software: Discord, Razer Cortex, MSI Afterburner, or FPS monitors can interfere with the compositor.
3. Corrupted SteamVR Configuration Files: A bad setting or corrupted file within SteamVR’s local data.
4. Overclocking Instability: An unstable GPU overclock (or factory "boost" clocks) can cause the compositor to fail under VR load.
5. Outdated or Beta Branch Issues: Using the SteamVR Beta branch or outdated GPU drivers can introduce instability.

What Error 475 is

Error 475 is a SteamVR runtime error that appears when the OpenVR/SteamVR runtime fails to initialize a VR headset or when the VR subsystem encounters a permissions, driver, or communication issue between SteamVR, the headset, and the OS. It often manifests as SteamVR refusing to fully start, showing an error code 475 in the SteamVR status or logs.
