Higher resolutions on powerbooks?

    I've got a non hi-res 15" powerbook that I'd like to register if MorphOS 3.2 will be able to support higher resolution external displays. If this is not happening, I'd prefer to register a system that can produce higher resolutions.

    btw lowendmac.com and similar sites report a difference in maximum resolution supported for an external display between hi-res and non hi-res 1.67GHz powerbooks. Is this a software, hardware or firmware limitation?

    On the topic of spec listing sites, they list my model as having 64MB but OS X and MorphOS show my powerbook as having 128MB graphics memory. Before I confirmed this I thought that might be the reason for the difference in maximum resolution...

    ?Non Hi-res Powerbooks have 64MB of vram and do not support the higher res modes of the 128MB vram version.
    I have one of these too, but I'm perfectly happy with the display limitation.

    The non hi-res 17" powerbook is listed as having 128MB and still can't, apparently, produce resolutions beyond 2048x1536

    "The maximum resolution supported on an external display is 2560x1600 at millions of colors."

    Apart from the non-hires 17" model with 128 MiB standard VRAM (as mentioned by ausPPC) there were also 128 MiB VRAM BTO options for non-hires 15" models:

    We discussed the latter one 2 years ago there:

    Andreas would (no doubt) be correct on this.
    Its never been an issue with me as I don't have an external display that would be legible at these resolutions.

    Possibly when I move to a G5/9800 combo I'll look into upgrading my monitor.
