Trash80toHP_Mini - sometimes it is possible that graphic card could have enough memory, but could not be capable of specific resolutions, especially in case of analog outputs, where specific timings of signal must be pre-programmed. It is usually easier in case of DVI output, where no D/A conversion is needed.

Exactly, that's what I meant by driver/RAMDAC compatibility. From the (always questionable) info on LEM, it appears that the Pismo will not do 1080p even with plenty of VRAM on board. So I'll be definitely be testing that! ;D

The split slow-side I/O bus of the NuBus architecture 1400 precludes any external monitor bit depth higher than that of the rare 16bit VIEWpowr card. The 1400 is the pick of the NuBus PowerBook litter in my estimation, so good luck in finding one over there.

Have fun with your DVI/Ti, given your requirements, that sounds like a winner to me as well.

As a side note: Ironically, the only remotely possible 1080p solutions I have available for NuBus Architecture Macs would be:

The very late Radius Thunder IV GX/1600 which is almost certainly hamstrung by RAMDAC incompatibility, given possible development of a 1080p driver.

The other is my very early SuperMac Spectrum/24 project card. That eager lil' puppy was built with all options wide open in 1989, before Video Resolutions became set in stone. One day I'll have the 720p/24bit and 1080p/8bit @ 60Hz timings and crystal requirements for analog VGA noodled out (or find someone who already knows how to calculate them) to put my pet IIfx (also 1989 vintage) into the world of HDTV LCD resolutions. Not too shabby for 25 year old retro-ware!
