mini dvi to vga - black border

Hi all,

I have look at the past posts and I have been on the phone with apple but still can't get my macbook to mirror to external display (HP, 22in, 1680x1050) fully. I see the mirroring working but I have a black frame around it.

Can it be that I have to use mini-dvi to dvi instead of vga?

Oh, one more thing, funny that I can use it perfectly fine in the extended mode (eg. there is no black frame around it)

Thanks for your help!

 

The problem here is that in clone mode, everything is cloned, even the resolution. Therefore wince the macbook is running at a lower res [1280x854?] than your external monitor [1680x1050].

You could try checking the menu of your external display to see if it has a stretching mode. Using the DVI input on your lcd may also fix the problem, I know that on my LCD a smaller than native res gets stretched to 1680x1050 when using DVI.

 

That's what I am going to try get some dvi-dvi cable and try that, if not then I will have to use it in extended mode.

I have seen so many posts here and at apple site that people get it working, maybe with the dvi cable more than the vga...

thanks for your help!

 

Well, its moreso dependent on your moniotr than anything else. I *think* my lcd has the option to stretch VGA signals.

 

Ok, I went and got the mini-dvi to dvi cable from apple and that one works, BUT, even though I select the external monitor to have the native res. of 1680x1050, the actual display is an exact match to my macbook (eg. I see exactly what macbook sees, but at 22in lcd, so i have everything sized from 13in to 22in. I am not sure if this is the best you could have or not, but probably I would not use this way and have the external display as an extended display, since that way I still keep the right resolution. Comments? thanks again.

 

You can't use clone and how two different resolutions. It just isn't possible. Your going to have to do some sort of streching, compressing, or pan & scan somwhere.

 

Actually, I managed to work it perfectly - keeping native resolution of the external lcd without being all funky. What I did is to set it up in an extended mode which worked before and then play around with how you see the two monitors under display settings...
