I recently bought a small BenQ monitor. On the back of the BenQ montitor was a VGA port and I didn't think that would be much of an issue. I bought a VGA to HDMI and it didn't work. Someone told me to buy VGA to HDMI adaptor so I did and that doesn't seem to be working either. The BenQ monitor keeps saying 'no cable connected'. To make matters worse, I put my normal HDMI back in the montior I've been using for years and now that doesn't work. I can see the BIOS screen when it boots up but nothing else beyond that. I'm having to write this on my PS4. Anyone any idea?
