Thanks for reply. Actually it's not my laptop, it's my dads. He wants to try and use his laptop as a second screen so he can see better in the field. He told me it had VGA in and I just accepted it, which is daft as I fix computers for a living and I have these sort of problems all the time (people making such mistakes). And now that I think about it, it is VGA out.
Is it possible to share the BP screen with a laptop screen? If not, are there any other options for viewing transmitted video on a bigger screen?
