MacbookPro wont detect external display

Hi
I have just tried to connect my MBP to an external 23" display using the vga-minidisplayport but my MBP wouldnt detect it at all? I've read many threads where other folks have similar problems but solution?

Any solutions? Please advise.

This same display works fine on my old macbook using the old adapter... both my adapters are genuine from apple.

Thanks

Welcome to the Mac Forums.

Instead of using a VGA adapter, use a DVI adapter from your Mini Display Port output. The 23" display (if it's a late model) should have an input for DVI. You can purchase a new adapter from monoprice.com (best prices) or from Best Buy.

Thanks, I am still wondering though as to why I cant use this vga adapter.. I have just bought it from apple and would really want to avoid having to purchase another one or having to go back to apple and exchange or return this...

Anyone else with this problem? found a solution?

Thanks

What is the make and model of the 23" display? That might help us to further identify the problem. And... it's always a good idea to use DVI if it's available as the clarity and resolution will be superior to VGA.
