I have a Windows based machine that inbuilt a few years ago. It's been hooked up to a Denon receiver then running to a projector for its entire life. Over the weekend, I brought the PC to a friend's place for a LAN party. I hooked directly up to an old monitor that he provided, using a DVI to VGA adapter. Now that I'm back home, I ran the HDMI cable from PC to receiver the way that it's always been, but the projector won't display an image.
I didn't have to change any settings to make the monitor work. It was just plug in and play. I don't have a monitor at home, just the projector. I've done a little googling but I'm having troubles finding anything helpful. Any advice would be really appreciated!
