White spots on the screen are generally caused by a bad DMD chip.Multiple elements of the chip remain continuously on causing these spots.Solution is replacement of DMD chip.

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.

No you don't need a driver, connect it using a VGA Cable, then press FN Key at the same time with Fkeys that has a monitor screen Icon on your keyboard.

Hope this helps.

Hi there my benq dlp projector is showing white spots on the screen when the screen is black can you help me?


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.

Our picture is yellow


first check the cable. second, go into the menu and reset the settings to factory default. this will reset any image changes and the resolutions. third, clean it out. dust collecting on the colorwheel will cause this, too. if you still have a problem and you just bought it, it should still be under warranty, so send it in to get repaired for free.

Benq 6110 - mounting projector onto ceiling


You need to navigate to the 'advance' menu and under the 'mirror' setting select 'ceiling front' or 'ceiling rear' depending on whether you are front or rear projecting. It should all be on page 29 of the manual.

Hope this helps

My projector Benq pb6200 needs cleaning from the inside how???


I have an Optoma EzPro 737 DLP projector that accumulated dust inside the lens and for ages I couldn't figure out how to get rid of it. It cast shadows onto the picture and scattered light outside the edges of the picture. I thought I'd have to dismantle the whole lens assembly (then realised that this is virtually impossible without being an expert). I then stumbled upon a little black rubbery plastic panel on the side of the light path, which unclips. I then realised that the dust had built up on the lens that sits in front of the DMD chip (the thing that makes the picture).

Here's what I did, with the case open and having vaccuumed out all the dusty parts of the projector to avoid making the situation worse:
- Took off the little rubbery panel,
- Removed the lamp from the projector and placed a flashlight inside, shining into the light path (or a mirror directing light from a table lamp above)
- Looking directly into the lens from close up, you should be able to see the particles of dust stuck to the inner lens (with a nice magnified view)
- First tried blowing air into the gap on the side of the light path (I used a balloon pump).
- Next, I poked a piece of thick nylon fishing line into the hole so that it could touch the surface of the inner lens.
- While looking into the lens, I could see the tip of the nylon, then directed it to the largest dust particles and used it to scrape them off (nylon is much softer than glass, so won't scratch the lens).
- This was quite time consuming but I got rid of the most obvious bits.

I'm not sure how different this would be for another model of projector - but I hope it helps!
