Windows Phone to support DPI-262?

Browsing trough the WP7 ROM dump, I came across this folder:
Code:
Phone_DPI_262
This seems to be a new resolution, because Windows mobile always supported DPI 192, 120 and 96.
Maybe this means a higher resolution for the coming Windows Phones.
Just a thought. Let me know what you think about it.

Maybe 800x800 or something. Sounds like an ugly squared tablet.

How do you know it's 800X800? I was more thinking about 1280X800.

Probably, but come to think of it.. Theres something called XGA and thats 1024×768.

To keep the widescreen ratio with 800x480 they would need something like 1200x720. Of course they are going to have other aspect ratios so I don't know.

This is a nice graphic that shows all resolutions...
I think WXGA would be the one that comes very close as it is 5:3 resolution just like WVGA.

262 DPI was actually mentioned by MS at MIX when they were talking about WVGA. I personally completely fail to understand what it means - it's supposed to be dots per inch, right? So without the size of the screen DPI is what exactly?

Well the screens won't get much bigger than the HD2 I think, expect if they're going to make tablets.

The problem is, the bigger the screen the lower DPI you should get at the same resolution. However, all VGA and WVGA devices previously had 192DPI in WM, regardless of screen size. So I guess it's a different thing here. What exactly it is I don't know.

That's true. I guess it doesn't tell us much, but at least it's bigger so either the screen size, or the screen resolution will probably be bigger.

WinMo 6.x supported 4 Logical DPIs (note that logical DPI is different from physical DPI, which is the bit that varies with each LCD panel/resolution)
96, 128, 131, 192
Note that a 5 inch panel might be operating at the same logical DPI as a 4 inch panel (lets say 192), but the physical DPI would be less on the 5 inch panel (larger physical pixel size)
If you were to change the logical DPI on a 4 inch screen from 192 to 262, while leaving the physical DPI the same (screen size/resolution does not change) - all on-screen elements would appear larger - more pixels would be used to draw each icon, scrollbar, etc.
Windows Phone 7 is showing 4 logical DPI's right now too:
96, 131, 192, 262
Just that we've lost 128 and picked up 262

Okay. But does that mean higher resolutions? Do you know if there will be higher resolutions?

The design of WinPhone 7 pretty much allows an arbitrary resolution, it's designed to be fully scalable. 1920x1280 @ 262 DPI @ 4 inches would make one ridiculous high res screen
As for what's in store, I wouldn't be surprised to see a large-format screen device like a tablet in the months following WP7's release.. but I don't have any specific knowledge of one yet.

Okay, yeah that would be indeed an amazing screen resolution for such a small screen!
A tablet would be very cool, I wonder if that's what HTC is working on.

Hehe nice one there. I'd like to know that too.

Maybe they need it for fully working HDTV support, although we're yet to see WP7 device that supports HDMI interface...

Possibly.
Zune supports it, so it would be odd if they wouldn't add HDMI support for WP7.

dont forget guys...higher resolution doesnt necessarily mean a larger screen.
you can still have a 1280 X 1024 etc etc higher res screen while still making it into a 3.7-4.3 inch screen.
hell you could even have a higher res screen into a 2.8 inch slot.
the difference with display screen isnt always about the resolution however its about the Pixel Size, the larger each pixel is the large the screen is, the smaller the pixels the smaller the screen.
just to give you guys a head up, at work i was wokring with an OLED Microdisplay screen that had the resolution of 1280 X 1024, YES better resolution than most HD TVS, however the display screen was less than an inch small, the reason is was because of how small the pixels were. its pretty cool.

Really, oh that's nice. Such screens would be really amazing on mobile devices.

Phase Beam Still Image

Hey guys,
I did some searching and couldn't seem to find a "Phase Beam" Live Wallpaper STILL image. I like the design of it, but don't care for the live wallpaper aspect. Any way I can get a HD image from the live wallpaper? Thanks in advance.
Sent from my GNexus

don't think theres any way to do it. closest thing would be a launcher that removes the statusbar and is totally blank and someone just takes a screen shot, but then you'd also need a custom launcher since you'd need to set no scrolling to get it to work.

Found one:

and i'll just shut up now lol.
only downside to that is that it's a little small for the Gnex. our wallpapers need to be minimum smallest size 1200. thats 960. so you may notice some loss in quality. or possibly not. the advantage of the high DPI sometimes makes low resolution images still look good on the screen.

Shouldn't our wallpapers be 1280x720 or 1200x720 at least?

i've seen many people say that if you want the best quality you need 1200+ on all sides.
possibly something to do with how android crops it. I've yet to try anything below 1200.
keep in mind, that though the actual on screen resolution is 720 wide by 1280 high, the real wallpaper resolution is 1480 wide by 1280 high because of how android handles wallpapers. so anything smaller will be lower quality.

I did not know that. Thanks for clarifying though.
Edit: Wait, did you get those mixed up? Shouldn't it be 1480x1280? Not 1280x1480.
You see, I only have one homescreen. So, I don't know if that matters. There obviously isn't any wallpaper scrolling.

yeah probably.
height should be 1280 and width should be 1480.
even if you have one homescreen, android still wants to crop a square wallpaper. thats been the issue since the G1. so if you want a portrait image, you need to use a third party app.
now, if your using a custom launcher then thats another story, as some when you disable wallpaper scrolling it gives you a crop for a single screen.

Wallpaper Resolutions??

Im sure others have noticed this in the past with pretty much all phones.
Why is it you always have to crop the pic when you make it a home screen wallpaper, even if its the same resloution as your display?
Example. the optimus screen res is 768x1280, why cant i have a wallpaper that size??
It crops the pic to a size around 600x800 , for arguments sake.
or for example , if you have on scrolling wallpaper why not a pic thats 5376x1280. This would be one full size 768x1280 pic for each of the seven home screens.
are there any apps/hacks to fix this.
just doesnt make sense, maybe im missing something.....
side note - i dont have any paint programs on my pc at the moment so i cant verify what dpi the images im using are. nor have i checked in the past, now that i think about it. it may or may not have anything to do with the issue
Thoughts?

I put in my own wallpaper - the image needs to be 1440 x 1280 for this phone. Are you talking about adding wallpaper for each of your home screens? If that's the case, check out MultiPicture Live Wallpaper. Yeah, the 1440 x 1280 image is cropped a little bit all around, no clue why. Same with my PC monitor - if I size wallpaper exactly to its dimensions it never comes out precisely right. Always have to compensate for that, depending on which sides gets screwed up.

After getting access to the factory wallpapers, I have found they are sized at 1536 x 1280 from LG . Odd size I know.
That is what I have created mine at and they work perfect without any cropping.

it's 1536 x 1280 probably because it's 1280 tall, and 2x 768 wide to account for wallpaper scrolling

If it's 1536 x 1280 then why does my 1440 x 1280 on the phone end up being cropped shorter on every side?

Like I said, that's the size of the factory wallpapers. Give it a try. 1536 x 1280. This is the home screen size. You will crop the sides for the lock screen.

Nah, 1536 x 1280 still crops off both sides and the top. Bottom is fine. Also tried multiple sizes to well below the given screen size and they still don't come out exact.
I really don't care, just wonder why this is.

Odd as that doesn't crop for me. Gives me the option to crop, but doesn't actually crop anything.

After going through a bunch of resolutions and aspect ratio wallpapers found here
http://topwalls.net/category/abstract/page/3/
Ive decided that the aspect ratio seems to be close to 5:4. It does still crop the edges but only slightly.
Resolution seems not to matter only the ratio. I've tried pics greater than 5000 x whatever and they work fine.
At the moment I'm using the Fullscreen 5:4 @ 2560 x 2048 and they look great.
Got my PC and paint programs back up and running.gonna see if I can find the exact aspect ratio and resolution size

In Photoshop I started to figure out what the precise figures were, but even when I loaded up goofball ratios and/or dimensions much smaller than the screen's 1280 x 786 (like 400 x 300) and then on the phone chose full width, the sides were still truncated. At that point I said - screw it.

[Q] Wallpaper Resolution

I've the Galaxy Tab 3 8.0, what is the wallpaper resolution so it fits the screen perfectly?

Your resolution in landscape mode is 1280 x 800. That will fit perfectly. However if you rotate to portrait then your image may not fit anymore. So if you make it 1280 x 1280 then it will fit, but some part of the image may be cropped. If the image is just a simple pattern you may not see the crop.

How is the display 806 ppi?

A 5.5 inch display at 3840 x 2160 yields 801 ppi, not 806. The display would have to be exactly 5.465 inches diagonally in order to yield 806 rounded off to the nearest whole number (both 5.46 and 5.47 will not). So why is Sony advertising it as 806?

it could be the dpi settings that the device uses
my Sony Xperia Z2 is 443 DPI but its advertised as 480 dpi and also has the dpi set to 480 in the system
perhaps the Z5 uses 806 DPI to make the UI not glitch out as it does with odd proportions when it comes to android/Sonys UI

Hmm possible. But shouldn't actual pixels instead of software setting be advertised?

not sure, its fully legal to advertise how many pixels the device renders and/or how many the display shows
