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.

[Q] Wallpaper Size

if i decide to use a wallpaper that isnt a live one what size/resoultion should it be to fit perfectly?
i know there are apps out there on the marketplace for downloading wallpapers but if i wanted to make my own id like them to fit perfect
Thanks

Height 800 pixels, Width 960 pixels, DPI 218
This is the actual dpi of the screen so you will get best 1:1 reproduction of the image.
The width being double is for the scrolling effect that Android has.
If Touchwiz does not do this, I haven't used it enough to know. Then make the Width 480 pixels.

Thanks for, not many good ones there though.
Anyone know where can good wallpapers for our Nexus, the default ones are poor.

Could anyone tell me the wallpaper size for the Galaxy Nexus? And maybe post up some good ones/links to good sites for HD wallpapers?
Cheers

I'm looking for a plain black one in case anyone can point me to one already made. I heard a black wall paper helps conserve battery power.

I'm just trying some wallpapers at the moment, and it's as annoying as trying to find one that fits well for a honeycomb tablet :/
And yeh with SAMOLED screens, darker uses less battery.

It seems like the existing wall papers have a size of 960 x 853 pixels.
I created this plain black wallpaper.

I don't know why the stock Wallpapers were released at that Res as they have to be upscaled to fit. Wallpapers for Native Res will be 1440x1280 if you want nice crisp HD.

Crop to 1440x1280 for your phone.

If I want a basic plain all-black wall paper, what format should I save it as? I know jpg works, but is there maybe a format that uses up less resources?

Plain black png will be considerably smaller I'd imagine.

I made a couple of fractal based wallpapers at 1440 x 1280, both using a black background. The second one is fairly dark, for those who want to conserve their battery without going completely black.

I don't think thats correct. It's a 720 screen so the native resolution would be 1280x720 (widescreen)

The wallpaper stretches to cover all 5 homescreens.

The resolution on one screen would be 720x1280. Across five screens it's 1440x1280.
The same as the old standard being 480x800 vs 960x800.

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
