+### Troubleshooting
+
+#### NVIDIA: No allowlisted displays found!
+
+1. See the logs:
+
+  ```
+    == Current Allowlist (8) ==
+        Sony SIE  HMD *08
+        HTC Corporation HTC-VIVE
+        HTC Corporation VIVE Pro
+        Oculus VR Inc. Rift
+        Valve Corporation Index HMD
+        Seiko/Epson SEC144A
+        HPN
+        PNP
+    == Found Displays (2) ==
+        SAMSUNG (HDMI-0)
+        HP Inc. (DP-2)
+  ```
+2. Identify which entry under Found Displays is your HMD.
+3. Add the following env var to the Envision profile, with the correct name for your HMD:
+  `XRT_COMPOSITOR_FORCE_NVIDIA_DISPLAY="HP Inc."`
