I have a PB7110 projector, I hooked it to my PC using an adapter and a HDMI cable. It has been working fine for some time, but now I keep getting the out of range error. I've checked the frequency on my laptop and it is set at 60hrz. I've tried different resolutions settings but nothing works. I don't understand why it is not working as it has been working fine in the past. I also tried using a USB cable but the projector did not find the connection. I've tried restarting the laptop and the projector several times because that is the only advice I could find online, but that did not help either.
It could be that your cable is bad, or it is that the projectors age is finally catching up to it. I’d try a new cable first, but if it is the projector, it’s probably time to get it replaced.
