Hi,
I see that the maximum dual-link DVI resolution for the ATi 2600XT is 2560 x 1600 (16:10). Can anyone confirm that a monitor with a 16:9 2560 x 1440 resolution would work with this card? I realise the Apple 27" display is ruled out due to lack of DisplayPort on that card.
Thanks

    I realise the Apple 27" display is ruled out due to lack of DisplayPort on that card.

    There is an adapter available:

    but it won't help if the card doesn't support the resolution. In any case, you could replace your card with a much better one for not much more than the cost of the adapter:

    I don't see 2560x1440 listed as a resolution my 30" monitor supports, but I don't know why the vid card wouldn't since it easily supports the higher resolution.

    The ATI Radeon HD 2600 was designed before the 2560x1440 display, so it may not support that resolution, even though it does support higher resolutions. If it doesn't it may be possible to force the desired resolution with SwitchResX

    or DisplayConfigX
