STATUS_CTX_BAD_VIDEO_MODE
The client and session display capabilities do not overlap
STATUS_CTX_BAD_VIDEO_MODE means that the requested connection reached a session whose video mode is not supported by the current client. It is a capability mismatch between client and session display handling, not automatically a failing GPU driver or a corrupted monitor EDID record.
RDP negotiates display-related capabilities during the connection sequence. Resolution, color depth, multi-monitor layout, graphics features, and the client implementation all matter; changing a server-wide display configuration before recording the negotiated request can remove the evidence needed to identify the mismatch.
Useful evidence
- Capture the client version, .rdp display settings, requested monitor layout, color depth, and the target session's active graphics configuration.
- Reproduce with a deliberately simpler supported display request, such as one monitor and a lower resolution, only to isolate the incompatible capability.
- Check the RDS host and GPU configuration against the supported deployment scenario before changing drivers or disabling graphics acceleration globally.
