Problem With Pc Connection
Hello.
I have a BenQ MP721 projector that's been working fine until yesterday. The same laptop, same cables, same everything, but today the projector displays no source when connected to the pc.
I've tried changing the cables, laptop, searching for source again, but still the same.
Any suggestions?
Best regards,
Kristina
