VGA touchscreen upgrade

[bigkingfun]

I'm wondering how feasible it would be to upgrade the touchscreen in an existing PPC to a VGA resolution screen? Assuming the manufacturer releases a WM2003SE upgrade for any given unit, and further assuming there is a VGA resolution unit screen available in the right size at some point, would the cost of this upgrade be worth bothering?

PPC Techs has LCD replacement screens at $159 for current models - would a VGA resolution screen be a much higher cost? And if it was available, even with WM2003SE would the current video chipsets be able to run the higher resolution?

Sorry, that's not sufficient -- you need to replace the graphics controller on the mainboard itself. That alone will make the cost infeasible...

You may want to look into a software emulated resolution like this one: Nyditot Virtual Display (http://www.handango.com/PlatformProductDetail.jsp?productType=2&optionId=1_2_2&jid=D1C9F2B8XC863F46EC6EXA9E7C397A2C&platformId=2&siteId=1&productId=16346&sectionId=0&catalog=30&txtSearch=Nyditot+Virtual+Display)

I tried it on my Toshiba e755, and it works good... but the screen is a bit hard to read at such a small font size. It comes with tweaks which help a bit, like bolding fonts and making them darker. It lets you run your PDA in landscape mode too, and set various different screen resolution combinations. You also have the option of zooming in at high resolutions (640x480), to get to certain areas of the screen, you would scroll around.

The only problem is that even though Nyditot will "display" VGA, there aren't enough "texels" on a QVGA (240X320) screen to truely display this resolution.

that's y in moving from a 240x320 to an emulated 480x640 - they squeeze four pixels into one, which creates probs on text...i tried it, even darkening the text doesn't solve it by that much.
