Not bad, considering it's free -- and if you have an older Pocket PC whose digitizer may be acting up a little bit, you might want to check it out. (Incidentally, the author has <a href="http://www.pocketgear.com/products_search.asp?developerid=5939&sortBy=name&sortByOrder=asc">quite a few different free Pocket PC tools</a> that you might want to check out as well. :way to go:)

So what am I missing, isn't this already built in? Besides checking for dead pixels, what does the alignment check do? OT, I thought the ipod skins where an infringement on apples ipod uniqueness. Anybody else scroll down and notice them.

What would be even better than detection would be fixing the problem... My old Jornada 568 for example logs stylus clicks in the centre-lower portion of the screen as about 1cm higher than they really are.

Could be done simply by intercepting stylus input and applying a simple warp transformation (matrices and all that). Could be calibrated by the user clicking on around 8x12 (grid) points dotted around the screen, with the software logging the true position and receieved position. A transformation would then be easy.

Problems:
- Intercepting the stylus might be dodgy...
- Speed might be a problem...
- Resolution might be troublesome...
- It might not work.

Still, if anyone wants to make some cash, go program it :) There are many users out there who don't want to pay £100 for a new digitizer (that's a real quote that HP gave me!)

For one thing, it may tell you whether or not your digitizer "spikes" -- if you drag the stylus across the screen and the cursor jumps.

It will also tell you whether or not the system is detecting your stylus tap as directly on the point of contact, or whether it's slightly above/lower, etc.

Thanks felixdd for clearing this out ;).

That's the whole point of making this app. The built-in one can only do the screen alignment, but it doesn't check if your screen is calibrated correctly.

'Cause i'd been using one of this kinda tools when I was using a Palm. But there was no similar tool available for PPC yet, so I just made one for this purpose.

I've had three Jornada 568s with this problem. Two of them made the device unusable. I got two replaced under warranty. The third one I fixed by purchasing a dead Jornada from a friend and fixing it. I sold the one with the bad digitizer to someone for parts.
