I dont have a BV7 but on a BV8 I press
Beo4 MENU (depending upon the source you may have to press twice)
I get a grey menu in the middle of the screen "SETUP"
On the menu there is "CONNECTIONS"
I select "CONNECTIONS" by scrolling down (v arrow on Beo4 diamond) and pressing (GO)
I see the "CONNECTIONS" menu:
AV1 .. AV2 .. AV3 .. AV4 and against each is its associated type of source device
So my AV3 has PC
I scroll down to AV3 and press (GO)
I then have a menu that says "AV3"
and has:
- SOURCE ....... PC
- IR SOURCE <-- is greyed out
- HDMI ........... YES
- VGA ............. NO
Then on my Beo4 I set it up to have PC in the list as follows:
- press the standby button (orange/red dot) and hold it while you press [LIST]
- ADD? appears on the Beo4 display
- press (GO)
- first list item appears flashing on the Beo4 display ... if it is not "PC" then press [LIST]
- keep pressing [LIST] until "PC" appears
- when "PC" appears press (GO) and it is now one of your soft buttons
To call up PC on your Beo4 now just press [LIST], [LIST] etc until you see "PC" and press (GO)
At that point the BV7 should indicate it is switching to PC mode and provided you have also configured the connected computer to be outputing to its connection you will see a desktop screen on the BV7
Hope this helps
First B&O (1976) was a Beogram 1500 ... latest (2011) change has been to couple the BL11 with the BL6Ks *sounds superb*
