Using PB 15" (Aluminimum) to drive a Dell 30"

saptarshi · 08-31-2007, 12:17 PM

Hi all,
I know from the specs that a PB 15" can't drive the Dell 30". However, hope springeth eternal, i attached a 30" to my PB and it works, unfortunately at 1200x800 resolution.
I have previously attached an 18" at 1400x900 (something similar) resolution to my laptop and the OS X recognized the higher resolution for the the attached monitor, my point being that the OS X on my PB can drive higher resolutions than the laptop screen.
So my question, well okay, i can't get 2560x1900 (Dells resolution) but is there some where i can up the resolution that I am currently getting?

Thanks for your time

Give DisplayConfigX a try.

The later PBG4 will drive dual-link DVI, and your big display should be supported just fine. If yours is older, then dual-link is not really possible, and your big display just won't be fully used.
Which processor speed do you have?

Mine is the older one (just before the October release,2005) at 1.5Ghz.

I would say that you are out of luck to get dual-link without trading to a newer PowerBook that supports dual-link. So, that big display would be mostly wasted. You will do well by going with a smaller display - 22-24-inch should be good, but look at the specs to see if that one needs dual-link, also.

Have you tried using the included DVI to VGA adapter that came with your PowerBook? Attach that to a VGA cable, and plug the VGA cable into your Dell. You may be able to get a higher resolution, or even full resolution of the Dell that way. Of course, you lose the all-digital advantage of DVI, but it sounds like that may be worth it to you.

Hmm,
that might be an option (the dvi-vga converter) but the Dell monitor is in my lab and not at home and I do not have access to the vga cables i.e the dell monitor only has (as far as i can see) those dvi plugs.

Well, it was good trying.

Really? What model is it? My Dell 24" model 2405FPW has a VGA input (they call it D-SUB) right next to the DVI, S-Video, Composite, and Component inputs. I'm a bit shocked that they would remove those for the 30".

24-inch seem to ship with both VGA and DVI, but not the big screens.
Funny to think of a 24-inch as a small screen!

I think I can safely say that 30-inch displays don't have VGA connectors. Although, I suppose that if you needed a really big screen with large images (lower res), then vga should be possible. All those pixels won't function without dual-link DVI.

From the webpage, it mentions that the 30" dell has only two presets
(http://accessories.us.dell.com/sna/p...175&redirect=1)

1280x800 (which i get)
and 2560x1600
But on the 24" webpage, VGA output is specifically mentioned
http://accessories.us.dell.com/sna/p...9&sku=320-5647

I didn't see VGA output on the 22". Strange.
