[Palm Treo 750 ROM Development] Ames:
Its not just a matter of finding any driver that supports 320x320

Let me offer a comparison cause a lot of people are more familar with the computer side of things. Lets say you wanted to run a 2560 x 1600 resolution monitor (like Apples 30" Cinema Display) on your desktop computer

On a desktop you would need:

Money: A lot of money :) Sorry I couldn't resist, lol. k, back on topic.

Screen: Not just any old monitor can run every resolution... you'd need one that did 2560 x 1600. No your Dell 15" flatpanel won't cut it... no matter how hard you try.

OS: You need an operating system that can handle the resolution... Windows 3.1 for example cannot.

Hardware: You'd need a graphics card that could run 2560 x 1600... no a Geforce MX400 aint gonna do it, nor will a ATI Rage LT Pro.

Interface: Slightly different than hardware, you need a connection that can run 2560 x 1600... a standard VGA (read traditional analog) monitor plug won't do it. You need DVI.. and dual link at that. This includes the port and the cabling. Obviously they need to be compatible too, you can't plug a VGA monitor into a DVI plug (and don't tell me about the adapters out there that let you do this, what the computer is actually doing is passing a VGA signal through the DVI plug). There is no actual conversion.

Driver: You need a driver that will support it, and no you can't use a Nvidia Geforce 8800GTX driver on a Geforce MX400 and suddenly end up with 2560 x 1600 support. You can't use an ATI driver on a Nvidia card either, if you were wondering ;)

k, now back to the cellphone world...

Screen: Got that covered if your taking one from a 680.

OS: Also got that covered if you are running WM6. Obviously on WM5 this whole thing would be no go.

Hardware: It is unknown whether the display adapter chip used for video output on the 750 is the same as the 680... it may be if Palm thought it was cheaper to produce a universal display adapter... but more than likely its not (thereby saving Palm money on producing the 750). Someone with technical documents may be able to determine this. If the adapter doesn't support 320x320, the next two sections are a moot point.

Interface: Even if the adapter is the same, the display adapter may not have all the display connector pins hooked up if they were deemed unnecessary... on rare occasions solder can fix this but more often then not it can't. They also have to be compatible signals... i'm inclined to believe they are because the connectors fit, but thats no guarantee. The screens may be expecting completely different inputs.

Driver: You can't simply stick any WM6 driver that supports 320x320 inside a Treo and expect it to work... the chances of the display adapters being the same are slim and this would be like installing ATI drivers for a Nvidia graphics card. The Samsung i780 likely doesn't use the same display adapter as the Treo 750 is my main point here. The Treo 800 (or whatever its called when it eventually comes out) might but have a compatible driver but its highly unlikely, assuming the device even supports 320x320 (though I think its safe to assume it will).

Hope this helps a little... basically i'm not trying to discourage anyone from trying this but its not one of those lets seem if it works kind of projects. It will probably require weeks of work if even possible (and theres way to many maybes up there for me to say it is).
