ERROR_CTX_BAD_VIDEO_MODE
ERROR_CTX_BAD_VIDEO_MODE means the client attempted to connect using a display mode that the target Remote Desktop session cannot support. The mismatch can involve resolution, monitor layout, graphics features, or an older client configuration.
Compare the client display request with the Session Host graphics policy, supported monitor count, and negotiated RDP capabilities. Reducing one setting for a test can reveal the incompatible mode without treating the account or network as faulty.
What to check
- Retry with a conventional single-monitor resolution and without custom graphics or multi-monitor settings.
- Compare the failing RDP client settings with a working client on the same server.
- Check host display-driver and Remote Desktop Services events if the problem affects every client.
