would an example of this be Silverscreen? Perhaps there would be a solution there and asking the programmer might lead to something?

Just ran across this app called Screen Prefs. According to the info, it "sets the default screen color/gray scale depth for your Palm Connected Organizer", using OS 3.0 or later. Maybe it will help with AvantGo...

Mark, please give us a review of ScreenPrefs when you have a chance.

It sounds the most promising of anything I've heard on this thread.

Does it give you the better greyscale pics/icons on AvantGo?

Thanks!

Here is a quick, down and dirty review of ScreenPrefs:

As advertised it shows up in the Prefs as an option.

My VDx had TWO options:
1-bit (B/W)
2-bit (4 Grays)

NOT Available:
4-bit (16 Grays)
Color (Was not expecting it anyway )

So, my review is that in all it does what its supposed to do. But, there must be something in the OS that limits the display to 2-bit. Based on the above I did not see what AvantGo would look like, as nothing changed.
--
Side note: Changing to 2-bit kicks the whole system into 2-bit mode all icons are now 2-bit instead of B/W.

Handspring's response? "The Visor's OS can not be upgraded, since it is stored in the ROM (Read Only Memory). As for patches, we do not have any such patch available at this time, however you might find some 3rd party software that might make it possible to use the 4-bit grayscale."

I wasn't expecting much more of an answer

Oh, well... the quest continues...

I just finished loading and trying ScreenPrefs... and I have to concur with HoloDoc... there is no visible difference between the 1-bit B&W or 2-bit Greyscale in AvantGo pictures.

I do also have FireViewer and it displays some really nice pictures in what it says is "16 level Greyscale"... perhaps it writes directly to the hardware???

AlbumToGo seems to work fine with 4-bit, too. Huge difference when toggling between 2-bit and 4-bit.

I noticed something with AvantGo on my Visor... The icon on the "home page" DOES show up in greyscale as opposed to B&W. Just compare it to the app icon in the launcher and you should see a difference. By fiddling with the contrast, I was able to get a little more clarity out of images, though still not really good. I then re-installed ScreenPrefs and tried it too by adjusting the contrast... there was no noticable difference. Of course, the contrast needed to be turned way up which obviously affects the rest of the system unacceptably.

Wow, I seem to have started my first "Hot Topic" in the discussion forum.

Mark, the little "A" icon on AvantGo always shows up in grayscale, even with the older version of AvantGo. The icon is only 2-bit, 4-level grayscale.

Just to help you understand, just go out to somebody who has AvantGo installed and ask them to add the Visorcentral website to their channels and take a look at the some of the pics in the Review section of VisorCentral mobile and compare it with ours. The difference is really night and day.

Looks like the end of this topic - we've hit a dead end. Looks like we won't get the nice 16-level grayscale graphics on the Visor until somebody does an update. :'(

I just donwloaded the latest update of PalmName from palmgear, http://www.palmgear.com/software/sh...amp;prodID=2456

Anyway, it allows you to "fake" the OS string. I changed my OS to v.3.5, but it did not seem to make any diference in AvantGo. Which probably goes back to the API calls in 3.5.....

Oh well.
