We have multiple Group 500 systems with 2 Samsung 55" EDC monitors connected.
When the system wakes up from standby, we somtimes have issues with the main display. The image is zoomed in at e.g. 400% (so the desktop image, not the camera image).
After a reboot / manual hot plug (HDMI cable) / new standby-wakeup , the issue is resolved for a while.
So we are having these issues with multiple Group 500 system, at different customers. Always the main screen that shows the problem (bad resolution?). We are runnin the latest software / firmware on our Group 500 system, and Samsung monitors.
