Re: VGA vs. QVGA



1. Play videos. Has anyone experimented with videos in both
resolutions played in both modes (matching resolutions and otherwise)
and is there a significant difference?

There is not that much difference between VGA and QVGA when playing videos.

What problems might I have if
I already have VGA videos and get a QVGA device or vice versa?

It all depends on the CPU speed of your PPC. TCPMP on current PDA's is
capable of playing most hi-res, 700-800 kbps videos without problems on
current (Wm2003+) PDA's. Older (PPC2k/PPC2k2) PDA's aren't.

2. Web browsing.

As opposed to playing videos, the difference is really significant.

3. Menus and applications, particularly if I add GPS and gaming apps.

You can use the higher resolution of GPS apps in, say, Destinator. If you,
on the other hand, plan to use your PDA for in-car navigation only, you
won't really need the high resolution.

Not many games make use of high-resolution right now. Please see the Games
section in my Pocket PC Mag Expert Blog (
http://www.pocketpcmag.com/blogs/index.php?blog=3&cat=36 ) for reports on
them.

4. Link the device to a computer/monitor or to a T.V. (standard, LCD,
plasma, dlp, etc.)

Everything depends on your needs. If you want fast screen mirroring, go for
Intel 2700G-based solutions (x51v, x51v). Otherwise (displaying static stuff
like Powerpoint slides) any model will do with a CF/SD add-on video card.

5. Will the VGA mode drain battery power

Nope. Well-built VGA PDA's like the Pocket Loox 718/720 or the HP
iPAQhx4700, contrary to what most people think, do NOT consume more power
than QVGA devices. It's only the not-that-good VGA devices like the Asus
a730(w) and, to a certain degree, the Dell Axim x50v/x51v that have
significantly bigger power consumption. Please see

or slow down performance at
a significant rate?

Yes, there will be some performance degradation, but in most cases it won't
really be a showstopper. FOr example, very few games will slow down
drastically because of the screen's being VGA (an example of them is
Adventurer - The Island Chronicles (
http://www.pocketpcthoughts.com/forums/viewtopic.php?t=40106 ) if my memory
serves me well).

I'm looking into all the pocket pc makes and models (overwhelming) and
narrowed it down to a few where the only significant difference for me
may be the screen resolution.

Regarding VGA (480 X 640) vs. QVGA ( 240 X 320), I'm planning to do
the following and wonder how the different resolutions will have an
effect:

1. Play videos. Has anyone experimented with videos in both
resolutions played in both modes (matching resolutions and otherwise)
and is there a significant difference? What problems might I have if
I already have VGA videos and get a QVGA device or vice versa?

2. Web browsing.

3. Menus and applications, particularly if I add GPS and gaming apps.

4. Link the device to a computer/monitor or to a T.V. (standard, LCD,
plasma, dlp, etc.)

5. Will the VGA mode drain battery power or slow down performance at
a significant rate?

Whew!

Thanks,

Don
