Question about BenQ PB7220 XGA DLP Projector Multimedia Projector
Hi there, i have a projector, i have tried connecting it to my laptop as well as various others. at first it gives the no signal alert. but then after some fine tuning with the display and resolution settings it comes right. can you please let me know on what the display settings should be and how i sort this problem out. because eachtime i have sorted the problem out it has been by complete accident.
Help me please

go into the menu and reset the settings to factory default. after that, select computer again and see if it recognizes it. you may need to change the resolution to match the laptop.

SOURCE: Hi there my benq dlp
This is caused by dust on the lens assembly. If you can remove the lens, clean the surfaces with a lens cloth. That should resolve the problem. It is possible that the there is dust in the optical pathway inside the unit as well. If the cleaning of the lens does not resolve the problem, the unit should be brought in for a professional cleaning. It is not suggested that anyone open up these units as there are fine adjustments that can be changed internally easily that could result in convergence problems.

You are missing one of your primary colors and this is usually to a faulty pin where you are connecting your vga cable to. It could be either the pin on vga port of your projector or it could be the vga cable itself. Please look at the pins especially if you are using one cable to try with all the compputer.
