Recognize macbook connect

To my knowledge there are no video drivers to output video on a Mac USB port in the Mac OS system. There are however, devices that connect to the USB port that will give video out on Conventional (VGA, DVI, HDMI, etc) connectors.e.g. http://www.newertech.com/products/viddu2dvia.phpMost projectors connect via VGA - what Projector are you using?

Dell projectors work best with windows operating system. Replacing the projector would still not resolve the problem since it is not compatible with Macintosh computers. I recommend that you contact Macintosh and ask if there is an available patch to resolve the issue.

Set the screen resolution to one which the projector can accept.

If you were using the Apple S-video adapter to connect to your Dell projector, please realize that MacBook models with NVIDIA graphics cards do not support this adapter. Otherwise, please be more specific about what model Mac you have and what adapter cable you are using.

use s video cable

Hello,
Your Macbook should automaticaly find the best resolution, if everything was OK. Is there any HDMI input on the dell projector? What projector is it? Is there is an HDMI input, you can use a HDMI to mini DVI cable: better picture and sound than VGA, and will probably solve your problem

Max does recognize receiver over HDMI-CEC.
The problem is that DVI output is for video only. Macbook won't (and can't) output audio via DVI. So yamaha receives only video signal via the HDMI connector. You can check that by pressing Option button on yamaha remote and choosing Signal Info - you will see info about video, but no audio signal present.

Hi contact me if the issue persist and post me a message here

You shouldn't need a driver as long as the Mac video system resolution can be matched by the Dell projector. Considering you are using a Mac Pro I don't think this will be an issue. Have you tried it and it didn't work?

There's no solution. it will not connect with macbook pro or any other mac. as on the phone with all technicians and they do not know what to do. I had the unit replaced and still would not connect.
