External Monitor Problems

Hello all,

I am using a brand new mini displayport to DVI adapter with my 13" MBP.

I am running a DVI cable to my monitor (Asus 22" 1080p)

I am getting no signal. It says there is no signal from the cable and the monitor goes into sleep mode.

I have the same issue with a DVI to HDMI cable as I do with the regular DVI cable. The monitor worked fine with PC and 360 through DVI and VGA respectively.

I think its either the adapter or the macbook itself.

Any ideas on how to test it or fix it?

Mine was doing that to me at first... I had to close my macbook and hook up a mouse to get the monitor to work as the primary display. Otherwise it would simply act as a secondary monitor.

That was kinda vague but I hope it helps... lol

No, i mean it doesn't recognize anything. The macbook sends nothing to the display. It doesn't function as anything at the moment.

It's like its not even hooked up...

Have you tried going from the mini display port adapter to a VGA cable and then to your Asus monitor? (That would mean purchasing another adapter) Also, you might want to set the Asus back to its factory default settings and see if that works.

I have a hard time believing that a new MBP 13" machine is not sending a video signal through its port. I guess it's possible, but not likely.

You've already ascertained that the monitor is OK by hooking it to a PC. The only way to test the cables is to substitute them with known good ones.

Regards.

Maybe I'll take the macbook to the Apple Store soon. They could probabyl test it with another monitor or cable...

Yea, I just used the monitor with the save DVI cable on my PC tonight. So its definitely either the macbook or the DP to dvi adapter...

i'll try resetting my monitor to default, though I doubt it'll do anything...
