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.

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
Do you guys believe we will someday have the new Sense interface from HTC Hero for the Blackstone?
http://www.htc.com/de/press.aspx?id=103534&lang=1033
In this article (only in german, sorry) they say that it will be available also for Windows Mobile:

yes we can!
lol yes.. i think so but it will sure take some time.. sad but true. altough i am looking forward a lot. android, sense and so on..
You can see it in action here...

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
I was admiring the Nexus specs recently and noticed that with the resolution specs it had "colors" at 65k. To get perspective I checked some other new Android phones and they were all 65k colors. Then I checked the iphone 3gs and it was 16million colors.
This seems like an outrageous disparity.
It has peaked my interest so can anybody explain what "colors" means and how 65k differs from 16m? Also, what does it have to do with the resolution, in other words, the iphone and nexus both have similar resolution (although the nexus is capable of much higher) so why would the less capable one have so much more "colors"?
Basically when google made the nexus one, they made sure not to include all those whimpy weak colors such as peach and pink. Thats all i've got =(

I know, I know, Windows Mobile versus Android, etc...but definitely good material and I think it answers your question reasonably well.

I second that.
Now seriously it has to do with the color depth a device can display. I believe 65K colors means that the color of each pixel on your screen isdefined by 16 bits, or 65535 different levels of colors (2^16=65535) - or a 16bit color depth. 16M colors means your pixels have a 24 bit color depth (2^24=16777216, or each of the Red Green and Blue values of the color can go from 0 to 255) that is said to be the maximum that the human eye can discern.
Now, this said, in the golden age of computing, when PC were not powerful enough to handle 16M colors all together, I used a 16bit color depth on my win98 desktop in order to have a snappier computer without sacrificing any quality (I couldn't tell the difference between 65K and 16M color desktops).
So in conclusion, to me, the difference is more theoretical thans practical, and I agree that having 65k colors on a mobile device is enough, especially because the usage conditions are different from a PC (i.e. direct sunlight and generally speaking on the go) especially when performances are important over eye candy.
So let the iPhone folks play with their wimpy pea greens and peach pinks, and be happy with your functional no frills 65k color availability.

Mh, just skimmed through this, I'm sorry, didn't read it before posting my previous... It's got all the info and then some...
thanks for the replies. I definitely want the best of the best to be available on my device but i guess in this case it wont be a big deal.
But I have noticed that when i download a movie, it looks awesome on my computer but when i put it on my phone I can see tons of squares (pixels?) when theres moderate or greater motion, which really makes the picture look pretty crappy. This is a different issue no? And is it common to all devices because of relatively small screen size or do phones like, say, the HD2 not experience this?
That, has to do with the compression. The more you compress a movie the more you will see those "squares"...
In a way I don't get it because the resolution on this phone looks a gazillion times better than the whyphone
Where did you see 65k? The nexus one has 16million colours.
The iphone actually has 18bit while the nexus has a 24bit colour depth
This info was taken from some site:
The number of bits used on the iPhone to display a single pixel of color is 18 bits, with 6 bits used for each of the Red, Green, and Blue primary colors. 18 bits can provide a maximum of 262,144 colors (2^18).
The iphone uses dithering to then emulate 24bit.
The standard on PC displays is True Color, using 8 bits for each of the primary colors, for a total of 24 bits per pixel. 24 bits can provide a maximum of 16,777,216 colors (2^24).

As a new member I'm not allowed to post links but I know I saw it on phonescoop among others. I couldn't find colors specs on HTC or Google so reliability of the other sites I read 65k on is admittedly questionable.

Post the links with spaces instead of periods after the www and before the com
64k = 64,000
16m = 16,000,000
If a phone has a display of 64K colors, then you will only notice 64,000 different kinds of colors; the rest or the 15,936,000 colors will be converted into a 'matching color'.
If you view that in a phone with 256K color display, same rule applies. Except this time, 256,000 colors will be unique while the rest will be 'matching colors' like different shades of blue can be changed to the nearest matching blue that the phone can suppport.
If a phone has 16M color display, then all the colors in the color spectrum can be viewed in it generating a very vibrant and clear picture.
But this is not the only judging criteria as pixel density plays a huge role. Two phone with 16M colors but resolutions of 480x800 and 320x480 will vary in display. The image in the latter phone will appear to be washed out as there are not sufficient pixels to reproduce the colors on to the screen.
This is a very old post but I thought of just sharing the info...

I read somewhere that although the LCD screen of the nookColor is 1024x600, the graphics chip is actually outputting at a much lower resolution and it is being scaled/interpolated to fit the 1024x600 screen. Is this why small text is hard to read and not as crisp as like on my EVO? This is especially noticable on widgets and icons like SwitchPro battery indicator. It's near impossible to read the battery percentage.
If this is something I can disable (font smoothing or something), I'd definitely do it.
I've never seen this problem on any of the nooks I've used?
Mine is crisp and clear.
really? it looks like microsoft ClearType is cranked way up. All the letters are fuzzy instead of crisp and clean edges like on a PC or an EVO. I've noticed it on every nook I've picked up.
This is the first complaint I've seen of fuzzy text. Did they have some kind of matte screen protector or something over the display?
I can't imagine a dedicated bookstore making a (supposedly) dedicated ereader without ensuring it had crisp text.
are you sure the app isnt upscaling, and designed for a small screen?
if they arent using vector images then they would blur in upscaling.
otherwise, i havent experienced anything at all like what you explain
Found where I read about the video output:
GPU Processor: PowerVR SGX530 Graphics Rendering: Open GLES1.1/2.0 Hardware Scaling: 854x480 scaled to 1024x600 Video Formats: .3GP, .MP4, .3G2 ** Video Codecs: H.263, H.264, MPEG-4, ON2 VP7 ** Image Formats: JPEG, GIF, PNG, BMP ** (same GPU as Droid 2 and Droid X)

I agree about the text, depending on what you are reading I do see a fuzz around the letters.
Sometimes its poor pdf quality.
I also think the video quality is kind of washed out and not as sharp as it seems it should be.
Glad I'm not the only one who is bothered by this. I certainly never noticed it on my wife's iPad and the nook should be crisper considering the dpi. UNLESS we are actually seeing an 854x480 output interpolated to 1024x600 instead of native like other devices.

From what I've read this applies purely to video decoding. Anything the OS renders from apps to text does not have this problem. That being said mine is incredibly crisp.
For those who say theirs is crisp, what are you comparing to? For example, the text on the xda app on my EVO is much much easier to read than the xda app on the nook.

AMOLED HTC Incredible with CM7.
I just made a close-up side-by-side comparison of it with the NC. The NC's text is actually smoother around the edges of the letters than the Inc's, while the interior of the letters looks more "solid" on the Inc, probably due to the physically larger pixel-grid on the NC's display. Note that this was from a viewing distance of about two inches.
To me, it's a wash. At a normal viewing distance, they appear about equal and both look great.
This isn't in any particular app, though. I have some of the same widgets and apps on my home screens, so I was comparing the widget text and icon labels.

Not really comparing it to anything. My iPhone4 is more crisp but it has a much higher ppi. It's just good overall, I mean your evo probably has more ppi(idk the evo specs) so I doubt the text would appear as crisp to that. I mean the text isn't blurry at all so I guess I'd say it's just as good as a book and better than a newspaper

That is not the nook's fault. What you are referring to is pixel density.
If you have a phone with a small screen at 840x480 versus a screen more than double the size only scaling a 1024x600, the pixel density ill be lower on that device.
Our pixel density on the nook is about 169
ipad is about 133
iphone 4 is over 300 which is why that screen looks so sharp
Anybody who says that the display is being generated at 854x480 and upscaled to 1024x600 is, well, wrong. First of all, 854x480 is not the same aspect ratio as 1024x600(the equivalent would be 820x480, which nothing renders in), so those claims are completely made up.
More conclusively, even a smidgen of playing about with any pixel-related app(Multitouch Visualizer shows distance between touches) will plainly show that the screen is, in fact, 1024x600. You can also look up the LCD panel type(see the teardown thread), or ask ANYBODY that is doing hardware dev on the thing.
"Blurriness" can result from poorly-coded apps doing a bad upscale on their graphics, or from you needing to buy glasses. But the device itself is 1024x600, and looks just fine to me.
What you have posted there are video upscaling stats. The nook hardware cannot process video above 852 pixels wide so upscales to 1024. With that said the nook color has been reviewed to have a higher pixel density than the iPad and I have never seen anything less than sharp text.

I think this is correct, I looked at a list of 16x9 resolutions and this is what I see:
WVGA 854 × 480 ~16:9 1.783 410,880 total Pixels.
and
Used in many netbooks 1024 × 600 128:75 1.707 614,400 Total Pixels
I think the 848 (close to 854) by 480 is their attempt to render 16x9 or close to it for video. But that is just my guess.
Posted from http://en.wikipedia.org/wiki/List_of_common_resolutions
Also, if you are not aware of it, there is a way to change font size when reading... I have never noticed any fuzzy text on the NC screen. Try a few different things and find your happy place.

I edited my build.prop and changed lcd density to 150. Everything looks much crisper. I snapped some macro photos of it before. Will post tomorrow.
The clue is in the question - will I be able to play my existing games and use my existing apps, or must I purchase new versions?
Windows Phone 8 will be able to run Windows Phone 7.x apps.
It will run 7.5 apps. And perfectly I might add.
Sent from my SGH-i917 using XDA Windows Phone 7 App
yeah it will be compatible with older apps but the sad news is that however the apps built exclusively for wp8 won't run on wp7 which is big let down for previous gen WP owners like me
Can anyone confirm the following, maybe by checking on an emulator. I read somewhere that W7 apps (480x800) running on a W8 phone with 1200x720 res (Ativ) will be displayed full screen, but are displayed with black bars top and bottom when running on a phone with 1200x768 res (Lumia 920). Is this true.
800x480 is a 16:10 ratio, 1280x768 is a 16:10 ratio, 1280x720 is a 16:9 ratio. Price question: which one will have to display bars for legacy Apps? Seems the problem would be with the 1280x720 phones like the Ativ S and HTC 8X not the other way round.
According to MS, neither resolution will display black bars.

This is not what I read online. Now I need to hunt the link. On the WP8 handsets, WP7 apps are either scaled 150% or 160%. As soon as I find the link I will come back and post. From memory, the Lumia will have black bars but the HTC 8X/Ativ won't.

I suggest you download the SDK and try it out then, since it has been released. Given that I was part of the SDK Preview group you can trust me on that one - the 720p Displays on the Ativ S and 8X have bars and the Lumia 920 does not.
