New large-display or HD Rosie device on it's way??

When I was doing a bit of theming a while ago, I noticed that lots of the drawable folders had references to a landscape Rosie, even though that wasn't being used. Now the 2.1 screenshots have leaked, we can see that there is now indeed a landscape Rosie..
Whilst theming a ROM for the CDMA Hero however, I came across folders in Rosie.apk such as 'drawable-land-800x480'. So could we be seeing a new Rosie device with 800x480 resolution?
edit - maybe it's not a large display device and actually a HD version of the Hero??

There is no such thing as HD on android or win mob devices nor will it exists in the near future, 800x480 dosent even come close to HD, im sure that the said folders are more of a default thing made with future wvga devices in mind

I'm not quite sure what you mean by that as the HTC HD2 has the same resolution, 800x480. I'm not talking about 1080p or something if that's what you're trying to get at..
Did you take back the HTC HD from your sig complaining it wasn't really HD?!
They didn't used to be in the roms, they have appeared in later roms. A bit like how there were references to the landscape mode, but they are only getting implemented in 2.1..

Exactly the HD isnt HD thats just a brand name, what i mean is the folder Structure is a generic one and with the release of android 2.0 that supports diffrent screen res's HTC are just getting ready for there new range of snapdragon powered wvga android devices

Yes exactly, that's what my whole post is about.
I just thought it was interesting, that's all

HD means high definition. And 480x800 on a phone looks damn HD to me.

480x800 is no where near a high definition resoulution but more to the point even if someone made a device with a high enough resolution 1200x900 for example it still wudnt be HD unless the screen was interlaced or progressivly scanned which there not anyway lol

You don't get what I'm saying. I am not talking about HD As a standard. Because your 1920x1080 may not be as high definition for a tv when the technology evolves. My point was all about pixel density, that wvga resolution is very high definition indeed for a screen this size. So the HD makes sense in device's name.

Yeah i understand what your saying and the image quality of wvga devices is of great quality (especially the TD/TP 2 they have the same res of the HD but the slightly smaller screen size really makes for a sharper image) lol but it duz my head in that we keep adding the HD prefix to things (Especially gameloft lol) when its just not true Mabe we should call it HSD lol

Wrong, it is progressive. Interlacing would be a monumentally stupid thing to do on a portable device. The only reason it is still here (aside from historic reasons) is to carry higher res on less analog bandwidth.
ALL images displayed on an lcd are progressive in the end. Lcd panels are progressive scan only AFAIK except maybe in rare cases. But that would require two matrices.
Sorry for eventual typos. I typed this on my hero ...soft keyboards suck.

guys!!!!!!
HTC Dragon is on its way soon! i guess it will be with a bigger screen too.

Is there a golden rule for LCD density?

So, the Streak's default LCD density is 160, but how did they arrive at that figure?
Is this setting really true to its "native resolution"? It seems like 160ppi is simulating a higher resolution screen. This is how I arrived at this conclusion:
I have an Evo and the text and icons on the Streak appear smaller than the Evo. Given that both devices have the same resolution (800x480), shouldn't the text and icons appear larger since the Streak's screen is larger?
Is it possible to find the true PPI that would yield a "1:1 pixel display"?
I set the ppi to 240 and the text and icons appear proportionally larger than on the Evo as would be expected.
So, why is the default ppi set to 160?

After digging around it looks like the native ppi is 187:
http://www.brighthand.com/default.a...ell+Streak+Google+Android+OS+ATT+Tablet+Phone
I think 200ppi might be the ideal density for this resolution and size display based on the Evo.
The Evo has a hardware ppi of 217 but its software display ppi is set to 240. So, if we apply the same rule to the Streak, then:
240 / 217 = 1.106 * 187 (hardware ppi of Streak) = 206 (software display ppi)
I noticed after doing this and comparing pixels in the icon graphics, the 200pi makes the pixels look sharper and less blurry (anti-aliased).

The reason its set to 160 is so it can utilize the screen size.
If it was set to 240 (like the evo) then it would like just a blown up version of the evo.
For example. the streak's default at 160 lists 3 or so mor apps in market then the evo. But with a simple edit of the build.prop you can set it to whatever you like. I know someone that has their streak set to 240 just because they have bad eyesight.
I personally like mine at 160 cuz i can view more stuff and really use the 5" screen. But the downside is some developers don't code their apps properly and they don't draw right for the 160dpi

True! And you could do that with any display. This example is kind of a stretch but my Panasonic 720p plasma can display 1080i. I guess it does it thru interpolation and shrinks the image so the whole desktop fits. The result isn't as sharp as a true 1080p display.
By going with 160ppi, are we doing the same thing? I'm curious what resolution it "emulates" by going that low?
As a developer myself, we never had to worry about ppi because pretty everything was as 72ppi! This is an interesting new territory we're moving into with all these different display sizes and resolutions.
But, something I want to understand and figure out a "best practice" or "golden rule" for
Oh, btw, I'm not saying tha HTC's hardware ppi to software ppi ratio is the "golden rule" but they're a billion dollar company, I'm sure they spent some time figuring out why they chose that ratio. In the end it's all very subject at the moment.

Keep in mind that at least with tvs everything's pre-rendered, on a phone it'd be more like a computer game or a desktop, it knows what to strech and what not to.
Android 2.x uses 9.pngs for a lot of strechable dialog boxes so that it should look good at any resolution.
Most apps also come with icons/images in multiple sizes so that it's streching/shrinking one that's already closer to the target size instead of only a single image to all sizes.
It's like the dpi setting in windows, it just zooms everything in/out, it's independent of the resolution. (though windows isnt as good at non-default dpi's, some icons do in fact look worse at non-default dpis since virtually all installs are at it's default dpi)

I find the Dialer crashes often with dpi=200.
Would like to run it 200+ otherwise?

you can change the density to whatever you want. dell liked 160 mdpi for a tablety feel and to utilize the large screen while most manufacturers use the hdpi of 240 to keep the ui elements the same between devices. i found that the interface has to be changed alot to suit this and choosing something in between is a bad idea as you get overlapping ui elements such as buttons and text fields, and things like blurry notification icons.

i would love to go to an hdpi only..not mdpi

I don't understand. Why would lcd density affect program functionality?
What is this? Windows?
I found a free file explorer that opens the file but won't save my edits. I assume I have to change the file to r/w, but I'm not sure how. Any thoughts?

I Used root explorer, change to r/w , edit .
Yes it does crash at times as the Dialer does not scale at all when you change density.
Anyone in Canada looking for a streak let me know.

DPI Settings (inquiry)

After reading some topics on the new JB rom I tried to see the dpi settings over XXLQ2 and it's set to 160. Based on the specs reports, the SGT P6800 has a rating of 190 (ppi). Wait, is dpi different from ppi?

Sorry, I could not answer your questions, but just wanted to say that after tampering with the DPI Scaling Settings through build.prop, I pretty messed up my tablet.
After changing the value and rebooted the device the screen stayed black forever.
Thank good I had a Backup.
So please tamper with care on theses settings.
Besides, do you have link for the statement that it is rated at 190dpi ?
Greetings

The "DPI" you see on build.prop is not necessarily related to the physical DPI/PPI of the device; it works as a guide for the OS. It is how the OS figures out the "size" of the device, and therefore how many pixels each UI element needs to use to have a "standard" size in centimeters.
Let's say an hypothetical device has a 1280x800, 7.7 inch screen. Let's say it uses DPI=190 (which matches the PPI you get if you calculate the number of pixels per inch for its physical dimensions). Now, an Android app asks for an icon on the screen with 0.5x0.5 inches. The framework looks at the DPI setting. An inch of the (logical) screen uses 190 pixels; so, the framework draws an icon with 95x95 pixels.
Our device has 1280x800 pixels (and 7.7 inches diagonal). When using DPI=160, Android estimates our display at 8x5 inches (about 9.5 inches diagonal). So, the same program asks for a 0.5x0.5 icon, the framework gives it an 80x80 pixel icon, which would have exactly 0.5x0.5 inches on that virtual 9.5 inch display; and is smaller than that on our 7.7 inch display.
In short, the DPI setting on build.prop is a way to adjust the size of all display elements on your screen. Lower DPI settings make things smaller, while higher DPI settings make them bigger. As for what setting is the best, only you can tell. I haven't messed with the DPI on my tab. My Galaxy S2 had a default DPI of 240, a "real" PPI of 213, and the best setting for me was at about 180 (fitting much more stuff on the screen). Here on the 7.7 I see the default as good enough. Some people complain that fonts should be bigger: those people could benefit from increasing the DPI.
Google Play offers you software based on your DPI setting. So, unless you use standard values (160-240-the 216? of the Nexus7), be prepared to see the number of apps available shrink a lot. Or, use a hacked Play Store that doesn't check the DPI...

Did anyone change the DPI without screwing the tablet up?
I've tried the JBNexus 7 port and its DPI is much better, but I dont like all the Nexus theming

[Q] Lower resolution to 1920x1200

The main complains I read about for the Nexus 10 stem from the extra high res display.
Would it possible... or dangerous... to have the option to lower the resolution when you do not need it so high?
1920x1200 would maintain the 16:10 ratio and still have a high res, but battery life and overall speed would surely improve greatly.
Anyone know of any reason I should not experiment with this?

Does it even work that way? You're still pushing a resolution of 2560x1600 regardless.

Actually just found this:
LCDDensity for Root
Does this work with N10?

Not sure how it would be dangerous to lower the res but wouldn't the picture quality degrade if you do this?
If you do this on a regular pc lcd monitor, everything looks like a turd.

That's just for changing the PPI. Something like how PA works. You'll just end up getting a smaller or larger version of the app.
There's nothing wrong with the resolution. Overall speed is top notch and battery life is pretty good. Most of the complaints are because of Chrome. Chrome itself is the problem though.
Don't worry dude.

To my knowledge, you can't directly modify what resolution the device runs at easily. You can change screen DPI easily, but not resolution (most, if not all apps only change DPI).
For example, changing the N10 DPI from 320 to 400 will make the UI look bigger, but games and everything else will still be running at native resolution, so essentially no performance change.
I imagine editing the resolution directly would require some source-code modification on either a ROM or Kernel level, or maybe even LCD driver, but I have no idea.
In any case, the N10 is fine at the resolution it's at, but a few non-optimized apps may not run ideally. I would say the CPU architecture is more to blame though instead of the screen resolution.

I don't know how bad it would look.... it is a small screen so would think it would not be as bad as on a 22+ monitor.

This is definitely true for games. Graphics intensive 3d games, like Shadowgun Deadzone, have a hard time running at native resolution on the Nexus 10. The game renders at native resolution even on the lowest graphics settings. Most maps are playable, but some have a really hard time. On an LCD display, the only way to scale back resolution, and still look reasonable, is to run at 1/2 resolution (4 pixels get rendered as 1). When the iPad 3 came out, many devs chose to continue rendering their games at 1024x768 to keep performance acceptable.
What would really help, is a way to fool a 3d game into rendering at 1/2 resolution. Playing at 1280x800 would still look great, especially if 4x MSAA was enabled.

If a game does not run well it is because the game is coded terribly, not because the resolution is too high. If we were able to lower the res it would help performance, but that is just a band-aid on the real issue of the developer not doing a good job with whatever they made. The GPU is running at its max potential, but it has enough power and bandwidth at stock speed that it can render any game that is properly made at 30fps.

DEAD TRIGGER has an option in a config file for screen resolution. I might imagine editing this file would tell the game to render at a lower resolution, but I'm not entirely sure. In any case, not entirely sure if any other game would have such a config file or resolution setting either.
GTA III has an option for screen resolution conveniently in it's in-game options. Setting it at 100% does cause a noticeable drop in FPS. Setting it to about 50% allows for (imo) playable, high FPS, without too much of a drop in overall quality. Pretty sure GTA III is just not "as optimized" as it can be though.

I respectfully disagree. Running the original Doom, or Crysis, at 2560x1600 are two dramatically different things. Does that make Crysis terribly coded if it doesn't run well on your hardware at that resolution? For pure aesthetics, I'll take a playable Crysis at 1280x800 over Doom at 2560x1600. I suppose using Doom in that example was not so appropriate given that it was programmed by God himself.
Given the tiny fraction of the mobile market that 2560x1600 makes up, I think it's pretty unlikely that we'll see games optimized for that resolution. Adding a 1/2 res setting for games seems like a far easier solution.

I know that two games can have very different loads on the system, but if you look at all the tech doc's for the device the Mali 604 graphics processor has enough power and bandwidth to just barely push 30 fps @ 2560x1600 with properly coded apps. So if something is not coded well, it will not be able to reach proper frames per second to run smooth on this device. Optimizing for a resolution and have optimized code are very different things.

[Q]Is it possible to modify the resolution of the screen?

Can the resolution of the screen be modified like a computer monitor? I'm wondering because we could increase battery life of the device if the GPU doesn't need to push as many pixels. I'm assuming its hard set though.

I'm no expert but I would expect the display controller is preset to only drive the display in its native resolution.
Even if you could change it I doubt it would save power. The same number of pixels would need to be sent to the display. You'd just be changing where the work was done. The display controller would have to use more power to scale the image rather than driving 1:1 to the display.

Please do not comment if you have nothing to add to a thread. Yes an LCD screen can not change the amount of pixels it outputs, its hardware after all, but the amount of pixels being processed by the gpu can potentially be changed and then interpolated to fit the native resolution of the screen. I was just interested in what people think that have more experience then I have with the device.

I don't know if it makes a difference but you can always change the screen DPI/density.

OP I've been wondering the exact same thing, I doubt it's possible though.

what the OP wants to do is akin to buying a Veyron then running it on one cylinder to save fuel.

Once again, thank you for your rude opinion that has contributed nothing. If you don't agree with what I'm asking about that is fine, just skip over the thread.

Would be interesting to see if this was possible

I looked into this quite a bit when trying to get better game performance. Changing DPI settings doesn't change the resolution. I'd really like a 1/2 res option, which would be 1280x800.... perfect for games. I couldn't find any way to do this, and I think it would need to be implemented at the kernel/graphics driver level. There was a post on the N10 gaming thread, where someone had started some sort of Google petition to implement features like this. The link from that thread had far more info than I can provide, but I got the impression that this isn't a trivial modification.

Bioorganic, can you post a link to the thread you mentioned? I plan on looking into tackling it myself if I get time, but if someone has already attempted I don't want to recreate the wheel. Thanks in advance.

Screen DPI =/= Actual Resolution. In short, changing screen DPI is basically changing the size of text and buttons, but not the general resolution those said things run at.
