Hey guys, are there any updates for the ipaq 5455 to speed up the display problem? Are there any software out there that are compatible to the new display chip?
Its been a while since I just visited those forums

I never heard of any display problems. what are you refurring to?

So far the only updates have been about the battery issues and memory.

I remember reading that article a while back. I have not heard of or seen any updates for the chip. But hopefully with the new ppcs from hp coming out and the new OS, this chip will probably be fully utilized.

Doesn't the e740 and 50 have the same graphics chip :?:

No, the Toshiba e740 uses the ATI Imageon 100 (http://www.ati.com/companyinfo/press/2002/4507.html) chip. The e750 also uses an ATI Imageon, but I don't know if it's the 100 or the Imageon 3200 (http://www.ati.com/companyinfo/press/2002/4570.html); the Toshiba e750 specs (http://cdgenp01.csd.toshiba.com/content/product/pdf_files/detailed_specs/pocketpc_e750.pdf) just say an ATI chip.

Thanks for the answer. I wonder what the e750 has, and to further this more off topic does it have the same problems the 545x have :?:

I'm talking about the many complaints I read last year about the display graphics being slow etc. I have not installed anything on mine yet.
but here is what I was able to find after a search on google:

Here's some information I've been compiling for some time now. Hopefully it will be useful to someone!

The graphics system is different on the 54xx and 39xx iPAQ's: The 54xx use a MediaQ MQ-1100 graphics chip which has the potential to perform much better than the proprietary chip in the 39xx iPAQ's. This MediaQ chip is a 64 bit processor w/ 256K SRAM that can easily refresh 3,000,000 pixels per second - and theoretically it can do 1 billion pixels/second.

(a 320x240 screen contains 76,800 pixels. A full screen movie at 30 frames per second requires ~2,300,000 pixels per second to be updated)

This is great for performance - and this graphics chip directly controls the LCD which allows it to directly draw to your screen (and it can control the LCD - saving CPU cycles, prolonging battery life, etc).

*The biggest 'disadvantage' to this change is that 39xx software is written with gapi's (graphics application program interfaces) that uses the CPU for many of the draw calculations and then sends this output to the LCD; This method isn't even possible since the bus does not have a direct route to the 256K sram on the graphics chip! So if you're running programs written for older gapi's (like gx.dll), your performace on a 54xx will actually be WORSE than on a 39xx since the CPU will be constantly wasting cycles figuring out how to get the graphics to the screen!

I don't think there is an SDK out yet that includes a GAPI that can properly utilize the MQ-1000. As soon as one is released (by microsoft probably), it should be simple to port all your 3xxx apps to use the graphics archtecture of the 54xx iPAQ's. (I don't know how the new GAPI is going to work; it's possible that your app will require tons of rewritting to utilize the MQ-1000... unlikely IMHO)

Once we see software compiled to utilize this graphics chip, we will see incredible performance increases on the 54xx models - This really is an impressive graphics chip that HP chose for the 54xx iPAQ's.

This information came from tech docs from MediaQ, HP & Microsoft. Feel free to distribute or publish this if you keep my name on it.

PPC2K3 should address most of the above issues. (hopefully)

This is the first I've heard about this. One of the things I dislike about the 5450 is the fact that PocketTV won't play full screen mpegs as well as my old Jornada 568. This, along with the XScale performance problems, would explain it.

I'm hoping (but not expecting) PPC 2003 will address both the graphics and XScale performance issues. The bus speed issue would seem to mean a trade-up to a 5550.

Any words on when it will be coming out?
Is it from microsoft?
No official announcement has been made about Pocket PC 2003, although it's expected around June, I think.

As for whether it's from Microsoft, who else would it be from? :-D Seriously, the base will be from Microsoft, but the update for any particular device will be from the manufacturer of the Pocket PC -- if they decide to produce one.

Hold on PPC2K3 -> Pocket PC 2003 ... that's a whole new version... not a service pack.. right?
Does that mean that I will have to pay for it ?
Yes, it's an upgrade, not a service pack. Whether you have to pay for it is up to HP, which (all at once) has not announced anything about Pocket PC 2003.

HP charged for the PocketPC 2002 upgrade for earlier iPAQs so they could do this again.

There are however a number of bugs in the 5450 that they haven't fixed yet (e.g. driver memory, WLAN). I'm hoping that this means they didn't want to waste effort on fixing PPC2002 when they were already sorting out PPC2003 for the very similar 5550 and that they will release this free as a "bug fix" for the 5450.

I've got no inside information or any reason to believe they will; it's just what I'm hoping they are doing.

Rumours of a upcoming ROM update for the 5450 here (http://bizforums.itrc.hp.com/cm/QuestionAnswer/1,,0x38d068da2286d711abdc0090277a778c,00.html). I'm sort of hoping it fixes everything that version 1.10 didn't, but it kill's my "Pocket PC 2003 as a bug fix" theory! :?

I'm with you Fred... I'm hoping that those of us who invested substantially in the 54xx series can have some of our grief compensated for by having the PPC2003 upgrade for free, or at a lesser cost than what they will charge for the other devices.

Of course this theory probably won't hold true; the OEMs, I believe, must pay MSFT for each license ... therefore they aren't going to be willing to give it to consumers for free and absorb the cost. There's a little thing called the "bottom line" that gets in the way 8O
