Ruth - additional information:
- The issue appears to present itself as long as any bluetooth devices are connected (mouse, pen, etc).
- The issue happens when the SP3 is wireless or when docked (with wired LAN and power).
- The issue can be consistently reproduced.
- The SP3 is fully updated.
- The MWDA does full 1080P every single time with Android devices with no issues.
I will be home later today and will test using my home MWDA that is connected to a different brand TV - I highly expect the same results.
