640x480 Problems?
Just wondering, will there be any software compatibility problems with the "new" VGA 640x480 screen (assuming it comes out)? Is it possible that some programs might not run or is that not an issue?

Compatibility problems will be with WM2003SE, NOT the VGA screen.

Thats what I was thinking, but what about apps that play games or videos things like that....just wondering if there might some problems with those trying to adjust to a large screen size.

i think its a pretty valid question.
you wouldn't be able to answer it till you tried it out though. most programmers try to code for situations like this but with a PPC you might see different results; hard to tell.
dang - i didn't realize it was 640x480. that is enough to make me toss the X30H and get the X50.

For games and the such, it might look a bit more pixelated, due to using four pixels to represent one in a slightly larger screen, but the difference should be minimal.

I wonder how WM2003se handles apps that set specific pixels... does it give every app a fake framebuffer and then scale it up if it needs too? Seems like it could pose a problem with gapi apps and other things that reference the screen directly.

My understanding is that VGA pdas run a pixel doubling QVGA mode for compatibility thats a function of 2003SE. Only the toshiba had a pre-se VGA model and they had a very poorly done proprietary handling of this. What I have read is that there are some performance issues for doing so in SE too, but to a greater or lesser degree depending on the model. Se supposedly handles it quite well and toshiba models upgraded to se saw an immediate improvement.
Hopefully the inclusion of hardware graphics accelerators on the newer models will make that a moot issue.
So.. SE handles it and has historically resulted in slow downs but, in theory, that should not be an issue going forward.
This is just what I have read, I have no direct experience. Your mileage may vary.
Regards,
Artuk

There are GAPI problems. But once again this is a problem with WM2003SE. Meaning that assuming Dell doesn't try anything crazy, or mess anything up, in terms of software (like Toshiba did with their e80x and WM2003) then the compatibility with QVGA programs will be exactly the same between the X30 and X50H.

Can you switch to a lower res for compatibility issues?

It just seems so weird to be talking about a resolution of 640 x 480 as an "improvement" for anything 
I still havn't joined the 1600 x 1200 bandwagon for my PC :hide:

320x240 = 76800
640x480 = 307200
307200 / 76800 = 4

Well it's mainly an improvement cause you're comparing it to 320X240. Which is really annoying when using it to mimic PC-like functions on a smaller device (excell, browsing internet, playing videos, etc).
So I wouldn't really compare the upgrade of QVGA to VGA as being on the same [lower] level as the upgrade of a desktop monitor with (S)XGA to one with UXGA.
