3M X75 LCD Projector switching slides from the remote with powerpoint??

Hi Dan_waddy

There is a USB cable that came with the Projector ( one end smaller than the other ) The smaller end goes into the back of the Projector and the normal 2.0 USB end into your PC - This enables you to flick through your slides with the standard Projector remote control.

If you do not have such a cable , you could get one from most good PC and AV shops.

Thanks for using Fixya !

3M Projection Panel


Based on your post/description, I will assume that you would want to connect a PC to a Projector.

For a 3M DY-0205-1002-9, pls contact:

3M Customer Information Center
Hale Avenue Business Center
3M bldg. 506, POCS Destination Code 0444
835 Hale Ave. North
Oakdale, MN 55128 Fax: 651-736-6320

or try

3M Visual Systems
(Fax) 512-984-5105
Email: OHP -

Should you opt for a replacement, you may want to consider DVI to VGA Analog Video Cable or similar products.

Alternately, you can use a converter box that will accept VGA inputs but whose output is DVI-D compatible. A fine example is VGA to DVI Converter/Scaler but of course any comparable brand/model should also work.

Hope that these be of help/idea. Pls post back how things work out or should you need further information.

Good luck and kind regards.
