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

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.

is it actually possible to change wallpaper (I mean a 480x800 pic) in all touchflo tabs?
Yes, do a search in this forum using your own title - you should get your thread and one other that will give you enough information to try it out.
Be warned though, the end result is slightly disappointing - the source image has to be 256x256 apparently - so you will need to take your 480x800 image and resample it to this size. The HD doesn't seem great at restoring the image without losing a bit of quality. Maybe there is a better way but I haven't found it yet!

yes I yet known that thread but I don't like that 256x256 result, I hope as soon as possible will be available a full customization of HD touchflo.
however thanx for the answer man
Yes, it should be that way. Don't understand the 256x256 limit and might see what happens if you use a bigger image. Seems a terrible waste on a device like the HD
One gripe I have with my Nexus One is the inaccuracy of the colors on its screen. They appear oversaturated esp. with the reds.
Is there a fix for this or will it be possible that a firmware update may fix this in the future?
My understanding is it could be trivially fixed with a firmware update. I think the reason none of the modded/third-party kernels have done is is because it would require special colour measurement equipment, and (given that the technical docs for the AMOLED are not publically available) quite a bit of patience.
See http://android.git.kernel.org/?p=ke...74950cb35551;hb=refs/heads/android-msm-2.6.32
-- you can see the RGB gamma tables. Tweaking these should be able to change the saturation, colour balance, colour temperature, and theoretically (mostly due to changing the color temperature) improve brightness and display life.
One disadvantage of AMOLEDs at this point in time [since they are relatively new] is the software isn't exactly up-to-date with the hardware... and like @hugonz, we need to have info abt the hardware to tweak the software...

That's not exactly what I said; it would be easier with hardware documentation, but the table looks pretty self-explanatory to me (for each brightness level there is a 7-point gamma curve for each of the R, G, and B components). I haven't yet rooted my phone but it's something I'll definitely look at doing once I start working on kernels (assuming no-one else does it first). Maybe I should try plotting the curves to see if that would inspire any kernel devs to try hacking on this issue now.
@hugonz, I understood ur point... but for us it's more a trial and error effort... and different AMOLEDs probably have different tweak values...
Well I hope it gets started as soon as possible.

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
Paul
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?
As I recently posted here. I currently have an epson and novatec evo.
One thing that made me say hmm is that the major difference seem to be things that are normally adjustable (monitors & TV's)
So how could we go about changing these settings?
In Linux I know you can use shell to change most things.
For example xgamma.
Speaking of which I believe those could be ported.. but this isn't XOrg, so could be hard.
Also I know ATI has aticonfig, which allows you to change those settings in shell as well.
We have Adreno GPU's by Qualcomm made specifically for phones, and I doubt that could be ported but it's another thought..
Is there any friggin way we can adjust these settings?
Any ideas? Kernel-tweaks, anything?
I feel like for the super-duper phones we have this can't be too much to ask.
I'll look into it more once I choose which one to keep and re-root but until then I was hoping I could get some community input

It's probably possible. There is SurfaceFlinger (the Android graphics library, think XWindow or Xorg). You can tweak temperature settings in it, or turn certain pixel colors on/off. We may be able to accomplish something with it by tweaking things there but I've never messed with it.
Another way would be in the kernel for the panel init sequences, but they may or may not be in there. You'd need documentation to know what all the values do. I think we have the whitepaper for the Nova panels but I'm not sure about the Epson.
Hope this helps!
Thanks!
Yeah I was looking into SurfaceFlinger after hackaday managed to disable all led's except red for the nexus.
That's definitely a possibility.
I'll look into that, hopefully i'll get somewhere.
Finally, somebody else brought this up; I made a thread about this a while ago but didn't get much out of it lol. It would be really cool to level out the purplish tint on the nova's and even just to have the ability to mess with the saturation and contrast and things like that. Has there ever been app that does this for other android devices? Maybe that could help.
i've thought it weird that there the adjustments aren't avaialable in phones yet. a $200 netbook has no problem changing these settings, but a $500+ smartphone has no options.
We gotta bump this thread and hope somebody gets some real good ideas lol.
I'll see what I can do, cause this is something every smartphone should be capable of.
I saw this thread and noticed it said it has the color fix, but I don't want to download it because it doesn't have the lagfix in it. But I don't see anything about the color fix in any other thread??

The color fix is new, not in the old voodoo kernels. The new one is sweet, just as fast as voodoo although the benchmark will tell you otherwise. Voodoo will be added to the new kernel eventually, so you cant wait it out and be just fine or flash away, follow the fncking instructions though.
MOD EDIT: Edited the post so it won't contain any words that may be construed as offensive.
Not at all trying to be a downer because voodoo color looks pretty awesome, but what do you mean by "just as fast as voodoo". Are you saying that the kernel is OC'ed to be similar in performance to the stock volt/clock speed voodoo kernel, or that it handles I/O differently like a voodoo ext4 fix...
I guess what i'm saying is that your post is a bit vague and i was wondering if you could clarify.. Thanks
I'm still trying to figure out whats wrong with the colors on the fascinate? I don't see the fix that the other phones might have required.

I'm kind of wondering the same thing. LOL.
SAMOLED Displays by manufacture display colors with a blueish tint. You can even see this tint in the reflection of the display when the screen is off. The Voodoo color fix attempts to remedy this. At this point it will only fix the color when the backlight is set to 100%.
Any news about Colour fix? When will it be released? This full brightess setting is pretty much useless, because - well, it´s just too bright...
Would it be possible to give us an interface to control these settings ourselves?
This is the most waited fix for me and I believe I´m not the onlyone.
