Whats the diff between QVGA and VGA

Hi all, well I make no secret of being a technological cave man so could someone please explain what the difference is in a QVGA screen as opposed to a VGA screen...? The Kaiser (and all its incarnations) is a QVGA isnt it? Cheers

QVGA = Quarter Video Graphics Array
VGA = Video Graphics Array.
really, QVGA is 240 by 320 pixels. VGA is 480 by 640.

......so the difference is 230400 pixels......

Many thanks for the info...

lmao nice calculation skills.

Qvga is 320*240 resoultion, VGA is 640*480 resolution
Actually I think QVGA is quarter VGA, i.e. VGA has FOUR times as many pixels. 320*240=76800 ; 640*480=307200
if i'm correct, the QVGA displays show everything like on a VGA display. For example, the buttons have the same size, also the fonts have the same size, the only difference is that VGA makes it being sharper. So you can say that this is scaled. Some nifty apps can remove this scaling, which enables you to show more on your display

device Resolution :confused:

Im Confused about how Device Resolutions work .
i mean like all new htc ppc devices have a 2.8" lcd yet the resolutions are diffrent like the htc touch hermes kaiser gene they all Qvga 240x320 but diamond also 2.8" but it has VGA how does it work.
the one Asus Smartphone has a 2.0" screen but its QVGA or but the HTC 310 and ipaq 500 voice messenger and maybe mpx200 are QQVGA its so flipin confusing.
So is the resolution set through registry or drivers or what? I read in the typhoon section of a Wm6 cooked rom being able to make the htc typhoon resolution to QVGA.

The device resolution is built into the actual screen. The resolution is the number of dots that are found on one row or column of the screen. QVGA has 240x320 dots that make up the screen matrix. VGA (at least) doubles these numbers to 480x640.
If you see devices that have the same SIZE screens (2.8"), but different resolutions, that means the DOTs are different sizes. A VGA screen will often have smaller dots than QGVA, and as such, better resolution that looks clearer to your eyes.
One can use software to emulate a lower-resolution screen on a higher-resolution device, but not vice-versa. So a VGA screen COULD be made to appear as a QVGA screen, but not the other way around.
Hoping this doesn't muddy up the waters for you even more,

in simple terms.
qvga (240*320) will consume same amount of graphic memory be it 2" screen or 2.8" or 3.5" or 1 square kilometre!
lcd screens are built with fixed amount of pixels, but density varies with size and resolution.

Thanks i Get It nw.
Another Question how come all Windowr Mobile device Are 65k none are Greater than that compared to Symbians 16 Million Colours i knw its the os limitation but how ?

It's quite a read, but THIS ARTICLE might help you understand. If you need more, an internet search should turn up quite a bit of information ... especially in some of the digital photography forums.

That Was Long flip
Yeah i get it now bigger not always better but being as that maybe my hp ipaq 514 compared to the 6110 Navigator the nokia looks better but i think its the brightness anyhow 65k is good. Its True what they say knowlage is power so people who dont know are mislead when the told a device is 262k or better thanks man

is there anyway use with vga resolution HTC Jade

Hi everyone,
I'm just wondering, is there anyway use vga resolution on our htc jade. My friend use his diamond with vga resolution. But i don't know is there any rom to support this feature or how can we cooke a rom for change resolution to vga? Thanks for your opinion.

It is impossible.
Read HARDWARE specs. The Jade's screen is 320x240 (qvga), Diamond is 640x480 (vga). That is the main reason why Diamond is much more expensive.

ok i miss some details thanks.

TouchFLO Future: Sense

Do you guys believe we will someday have the new Sense interface from HTC Hero for the Blackstone?

In this article (only in german, sorry) they say that it will be available also for Windows Mobile:

The famous multi-touch feature is there aswell.
The Hero looks awesome, but the screen is kinda small.

i was reading up on this on my rss feeds and the article i read said they that are thinkin about possibly porting this over to the windows mobile side which would be nice
in a way it reminds me of pointui a bit but if your lookin for something along those lines for windows mobile right now then ponitui is there
The Sense UI (or as HTC terms it, "user experience") riding a capacitive touchscreen offers a people-centric approach to managing your information that is absolutely dreamy at first blush -- though it shares a lot of TouchFLO heritage. In fact, HTC promises to have a very similar Sense-branded experience for Windows Mobile.

Usually, a new HTC device means new GPU drivers and a few tweaks, but now, we could get a whole new UI! That said, we'll have to wait for a WVGA HTC device with this Sense UI before it will look half-decent on our blackstones.

Half the juice on our phones is taken up by Windows. What would be awesome is if we can port Android. Another interesting thing to note is that Hero has a capacitive screen so I'm guessing it'll be a better experience (with multi touch). All said I can only drool. Wishes and regards to all the great chiefs

I think it includes a software multitouch system, because comparing specs of both devices, in the Screen we see:
HD: 3.8-inch TFT-LCD flat touch-sensitive screen with 480 x 800 WVGA resolution
Hero: 3.2-inch TFT-LCD touch-sensitive screen with 320x480 HVGA resolution
I know that Hero have multi touch because I saw it at the video presentation.
Let's hope that's true

yep, noticed that too and thought the same...

It does have multitouch, I read it in a review

Garmin XT

Garmin XT on diamond is slow as hell.
I think it is because VGA.
So possible to run it in qVGA on VGA display?
Anybody knows?
