Please see the attached log. External display (iMon) shows very often information of the channel which was on before the channel was changed. This happens very often, at least when channels are changed from the EPG.

What happens in the log:
- TV is started with channel #1
- I go to EPG, select channel #2
- At this point, the iMon display shows correctly information of the program in channel #2
- I go to EPG, select channel #3
- Display still shows information about the program in channel #2.
