Hi again Joeworcs,
I believe you can only get the tuner or coaxial source into PIP, but I may be wrong. Again, as I'm a US rep, here's the Samsung UK portal for support on that product: http://www.samsung.com/uk/support/model/UE40ES7000UXXU
I regularly use HDMI 1 for Sky and would like to be able to see my IP camera in PIP which is on HDMI 3.
I can only see selections for channels on the TV's built in tuner. Is there a away of view a source in PIP?
