Viewsonic VG2030wm not detected on DVI

Hello,

I got a MacBook Pro 13' and purchased at the same time a Mini DisplayPort to DVI Adapter to use with my ViewSonic VG2030wm. To my surprise, when I connected the monitor absolutely nothing happened, it goes completely undetected. The monitor works perfectly fine with a PC using an Nvidia 8600 through the DVI connector. I tried with both a single and dual link cable. I seem to be not the only one with this problem since I've found a few posts around but with no answers.

Later I exchanged the DVI adapter for a VGA one and the monitor worked fine but I would like to be able to use the DVI quality. I've asked twice at the Apple store and nobody has heard of such a problem. The monitor specs say it has a DVI-D (with HDCP) port.

Any ideas?

Thanks!

Hector

As wisely suggested by someone in this thread, I did contact the Viewsonic technical support, but to no avail.
For info, here is a copy of their latest message:

Dear M. XXX,

I double checked and we found no related problem or reported problem as yours. This might be an isolated issue with your unit.

Try the monitor on a different computer with DVI to make sure.

If all else fails, monitor may need to get repaired due to hardware failure over DVI. Please verify your complete shipping address.

Thank you for giving us the opportunity to assist you and supporting ViewSonic.

Sincerely,

Rxxxx

I don't know about you, but with this kind of technical support, I'll be looking into different brands next time I buy a screen.

My Viewsonic VA2216w was not recognized by my macbook pro 15" unibody july 2009.
But now I found a solution that works all the time.
Allways do the following:

1. monitor and macbook are off and non connected
2. switch on monitor first
3. wait until it goes to sleep with the light turning from blue to yellow
4. plug vga and connect monitor to macbook
5. switch macbook on and you got your Viewsonic recognized.

If you close the macbook cover, when you will open it again the Viewsonic still works.

It is important to have the Viewsonic switched on BEFORE you switch on your macbook. I don't kow why but it works. I suppose the problem is that the Viewsonic don't send messages as fast as the macbook needs.

Greetings,
Marco
