Colour Depth Difference with live / normal wallpapers

Hi Guys,
I've seen some discussion around the HD2's screen colour depth.
I've been doing some experimenting and have found that the colour depth is decreased when using a live wallpaper.
Im using the Darkstone's Froyo V1 Build with Cotulla's latest zImage. I havn't tested with the Sense build yet...
Give it a try :-
Set a Live Wallpaper
Now Add The Analogue clock widget, power control and Home Screen Tips widgets to a blank desktop.
Notice the Gradients of the widgets look blocky and appear low resolution.
Now apply a normal Image Wallpaper and you'll notice a real increase in quality of the gradients in those Widgets
I've taken screenshots to show you but when the screenshot of the Live wallpaper is looked at on the computer it looks perfect so must be an issue with the Way the HD2 is displaying it..
Here's the 2 screenshots :-

goodness me, does every little detail require a new thread?

Dont read them if your not interested?
This is something that no-one has noticed so far and actually could be quite important - now why dont you go back to your 9million page thread and continue pointing people to post#4 like the real helpful fella you are eh....ffs

Yes, it's especially noticeable on the anologue clock but not on the pics you posted up. Didnt notice it at first. Sharp eyes you've got there. Lol

HD2 has poor colour quality from the get go, running multiple applications let alone an OS that is overlapping another OS on top of of multiple applications running in the background is bound to have more than some effects, least of all important right now being the colour. I have no idea what you're talking about, but perhaps a quick browse over the forum rules would be a good start, it isnt 9 million pages long so you shouldnt have too much trouble. The least you could do is post in a thread of whoever ROM/Android release you are using.

Yeah unfortunately they look normal on the screenshots i took for some reason which leads me to believe there's an issue with the way it's been displayed on the HD2.

First of all - the point of my post was to 'Prove' that the HD2 can display more then 65K colours as was first thought, if you'd read my post at all - what you've posted above is a complete nonsensical response.
This IS important as people 'like you' seem to think the HD2's screen is of low quality when in fact it isn't.
Maybe you'd have an idea of what im talking about if you took the time to read my post instead of 'trying' to be a Mod?
Maybe you should peruse the Forum rules and then you may in fact realise that i havn't broken any of them?
I wasn't moaning about it not booting, GSOD, SOD, No Sound etc i posted a unique 'observation' that may help in the further development of 'proper' graphics drivers for our port.
I also wasn't moaning about a bug of this particular build - so why should it be posted in the Thread for that build?
I just think some people around here have a chip on their shoulder and are trying to be something they are not - & you dear sir are not an XDA mod.

...whoa...nice...calm down guys...calm down...

Yep, no reason to get upset. I think that's a pretty interesting point you found there. Do you have any opportunity to store the screenshots into a lossless format? I really can't tell any significant difference from the two jpg´s you've posted there - been watching the two for about a minute and i can tell you that my eyes are known to color difference detection

i think it's better a thread like this than the 2348740860th always about "no booting, no sound, no radio, no android, no intelligence", all completely useless if the author read the forum form 5 minutes before posting, this thread is about a new "problem / symptom" and it's not useless... maybe it's not importante now to obtain 16m colors, but it's always something that can be fixed

on topic guys Dev forum not flaming
Keep it peaceful

i haven't really used an actual android phone (day to day) but im sure Google put that in there, because of Live wallpaper taking up CPU power thus lowering the quality of widgets.
EDIT: and the pics look EXACTLY the same (except for the wallpaper and time of coarse.)
but, on the device itself it is less quality, ive seen it before and thats why i use a static wallpaper.

Hi guys, yeah as i said in the post for some reason the screenshots taken directly didnt really show the difference for some reason.
I've taken some pictures using a camera and the difference is clearly highlighted here.
Cheers

I installed a live wallpaper on my Desire V5 build and noticed that the moon on the weather portion of the Sense clock (it was a clear night last night) changed color and looked a little more green than gray with the live wallpaper running. Don't know if its a bug or not, but it's just my observation.

Sorry to resurrect this ageing thread but it at least shows I bothered to search for it.
I seem to get this effect on some ROMS more than others, I also get it on the wallpaper itself but only for some.
I am thinking that it must be the wallpaper itself for me, it must be in a colour depth beyond the capabilities of the phone. For instance if I install the honeycomb ADW theme with the wallpaper enclosed I get this effect on the wallpaper.
Couldn't see any other threads about this, any ideas anyone?

[Q] Pixel Quality? Error?

So quick question XDA. I noticed on my HD2 running FroyoStone 3.2 the pixel quality is bad...I wouldn't even say "pixel" cause its just the textures on some things. I took a screenshot of my phone to show you what im talking about but it showed up better quality then it actually is... Confusing right? Well take a look.

The shaded black part behind "Speak now" is actually good quality when i took a screen shot...even though thats not what I see?
This picture was taking with my camera

Click to collapse
This is what I see, Notice how the shading or the black part behind where it says "Speak now" is really bad quality.
Thats not the only thing that has bad quality. When I receive picture messages all the pictures are really bad quality. Also the pictures set for each one my contacts are bad quality. Is this something I can fix? Please and thank you.

If you really see what we can see on the pictures, then a a fix is available.
You only have to wear your glasses
The pictures are really bad. Maybe you should take a look in the manual of the camera and search for "focus" or "autofocus"

Compare the two images. The first one is what i see on my phone when i use it. The second picture is what it should look like.
Also I took the first picture with my moms phone, i sent it to my HD2 without changing the file size. When I received it on my phone it was sent as a 4 KB file and which is a really small size. It does this to EVERY picture I receive. Yet its only when im running android (FroyoStone 3.2)
For example...

I think I worked out what you're saying OP. I just checked mine and it's exactly the same. It's probably due to the 65k colour screen as opposed to 16million colour screens most phones have these days. It's nothing to worry about.
Someone correct me if I'm wrong.

Okay well is there a way to fix the file size, cause every picture i receive is really small and blurry.

That's what we think. I don't think anybody has been able to prove/disprove that the HD2's screen is only capable of 65k colors; it could just be a WM limitation, and the devs have yet to 'unlock' the 16mil colors using Android. (Of course, I could be wrong, but like I said there's no proof.)
The problem is the color gradient -- it's easy to detect the low quality of the images due to the gray gradient.
Concerning the MMS sizing, I think I encountered a fix for that, but I haven't tried it. I can't help you look for it now because the sub-forum search is down.

Okay well i only get low quality pictures when im using andriod, if im just running winmo its fine. So do I need to get this rom? I've never changed roms before, i don't even know how to do it.

[rom-dev]Colors Display Improvement (ReSaturated Method)[Test])

Hello everyone!
As we all know we have only 262k display colors .and this so sad.....But i think i found the way just a little improve our hd2.How? Ok just look at this two pictures:
The first one is original:
And this one is resaturated:
Of course on a PC it look wrong , but see it on hd2!!! It looks great (just tranfer the both pictures on your hd2 and compare)!!
Here are two more examples
And I thought - why this method does not apply to the rom?
And i did it. Of course to make such arms just commit suicide, because in rom about 15000 graphics files.Therefore specifically for such purposes, I wrote a program to automatically adjust images in the rom. Of course not all so rosy as it seems at first glance - some parts of the interface (how it happened for me) do not look as they should and there is a logical explanation - they have to edit manually, although they are quite suitable for automated processing of their "parameter". Some do not treat - the system becomes not working.I almost understood what exactly, but to understand the nature of such "intolerance" I have not yet succeeded.
The program still raw and needs refinement, but see the result of a fully automatic processing of the firmware you can now. As a basis took imilka inc s 1.1. Firmware works the same way as the original. There are weaknesses in some elements of the interface - as I already wrote such places must change hands.
This rom not for daily use.It`s just to see "how it looks".
If you interesting you download it, you flash it and give me your opinion to this topic.

Restore lost contrast on the NSTGL

Have had my nstgl for about a week now and while when I'm reading it it's 'OK', anytime I take a look at the sharpness of a normal NST I get a bit miffed. I know contrast can be upped using the NoRefresh hack but that it obviously unsuitable for reading. I also know that there was a noticeable increase in sharpness between NST firmware 1.0.1 and 1.1.0. So: does anyone have any inkling on what, exactly, changed between those two old firmwares to make the text sharper (and more ghosty, yeah...)? If we could figure that out, maybe we could figure out a way to mess with the sharpness on the Glowlight...? I just have no idea of where to look. But maybe we could start the ball rolling here!

Discussion and question threads don't belong in the development forum.
Thanks
AvRS

It seems to me the proper way to go about this is to try to figure out what changed between 1.0.x and 1.1.x in terms to making the text darker, and then attempting to intensify this effect. I thought that the EpdController inside framework.jar had changed but it looks like that isn't the unless, I diffed the wrong files.
Thoughts anyone?

I thought that they changed the fonts or font rendering.

Did they indeed? Well the fonts I can find, but what controls font-rendering, I wonder...
Thanks for chiming in.

[SOLVED]Split screen

Hi again,
i have problem, my hp pavilion dv5 have 1280x800 screen and i cannot split screen in windows 8 like on screenshot. I know i must have min.1366x768 screen but maybe there is option to unlock this option in lower resolution.

Possible I guess. By using the resolution hack, I think you may achieve split screen. It's using the netbook screen res method, you hack the registry to show more screen resolution options. Gives you more, but it looks cramped, blurry, with uneven pixel density. That's putting more pixels than the actual screen may support. Another method you can use is plugging an external display that supports 1366x768 and up. This will definitely allow you to have that split screen.

res registry hack doesn't work anymore. Haven't found a way to do this yet.

Okay, solved. If you have nVidia you can add other resolution via nVidia Control Panel. Now I can split on my 1280x800 screen with resolution 1366x856

ATI Radion HD?
Hi all
I have the same native resolution as the OP but my laptop has an ATI Radion HD graphics card.
Does anybody know how to add an additional resolution with this type of card?
Thanks and God bless
andrew-in-woking

Check ATI software, maybe there is option to add the "adjusted resolution".
I checked it in nVidia software and Intel also ( HD 3000 ), and i can add other resolution ( higher than native ).
Regards

I use an nVidia based Graphics Card and this is how I change my resolution, in case anyone wanted to try it out! And yes, snapping works perfectly after this but your monitor might not display it all very clearly.
I have a Dell monitor as you can see in the screenshot running on a native resolution of 1280x1024, just like the OP's! \

After changing the resolution from 720p to 768 by my Radeon,its looking bad,I wanna know that, it shud look bad isn't it,I mean it's obvious to look bad in upgraded or downgraded resolution?can't we do sumthing 2 run those apps in 720p,well if sum1 mod the apps into compatible resolution...well this may b a noobie question,well I don't wanna use those apps in BAD LOOKING SCREEN THAT'S ALL

What I have observed from using Split Screen is that, each app has a minimum running width of 1024px wide, anything lower and it will look cropped and uneven. So even if somehow the people at XDA bypass that option and allow snapping at lower resolutions, it will still look bad.
It's not such a great feature either, you keep getting confused on what's running and hard to concentrate on one app when there are two taking up the screen. Multitasking was made for the desktop version and it should stay that way in my opinion
