Hi @santa
Test on HDMU 12197 Spark7162 ...
For HDMUCenter: Plug Control & Settings:
On these OSD function, Exit key has not been mapped to exit from config items page!
Now ... the Exit key is mapped to change status of the items value in the list ... and to exit (without changes) you can select only the green button (Save)!
This can create problems, if you do not notice any unwanted changes!
Ciao ...
