Hello All,
I have looked around different forums hoping to find an app or setting info which allows to modify the screen color, contrast and Gamma . I haven't been able to find any .
I have a Vega Tegra2 replica which has high screen brightness ( faded black colors ) and I am running Vegacomb 8.1 on it.
Can any one please tell me if such an app or modification exists?
Many thanks !!
Anyone has any info?
Sorry, don't know anything that can do it. But it's a nice idea.
It would be very helpful for those that have cheaper tablets/phones and want to improve the screen quality and picture.
Im wondering how come no apps is around? Any limitation on Android OS to handle this or harware limiation?

Hi.. I just flashed my GS2 with Super Nexus rom..So far it has impressed me to the core..everything is working properly. Kudos to the developers.
I just have one slight problem with this rom..the colors of all the photos, wallpapers have very very high contrast..it is difficult to look at them..Is there any way to reduce the brightness, contrast of the phone..I tried the default 'adjust brightness', though it reduced the phone brightness, the brightness and contrast of the photos and wallpapers is still very very high..Is there a way to adjust it?
Thanks in advance

I don't know about super nexus but on Samsung based rooms and even usually on AOSP/ AOKP roms there is a setting to change the screen mode. Try changing it to movie which I think is the "dullest"

Hi guys, has anyone fooled around with the new color tweaks avaliable in perseus 32.1?
I'm currently running my phone in movie mode which gives it much more realistic color saturation but I'd be open to some further tweaks.
I've heard that unchecking "autoadjust screen tone" improves the quality but drains the battery.

>Change Screen Resolution<
Introduction:
I'm going to write this guide to teach you how to change the Screen Resolution of your Xiaomi Mi3/Mi4 AOSP/CM Based ROM to improve the graphics performance of your Mi3 without stressing your CPU/GPU while playing games.
What you need to Download:
Resolution Changer by NoMone:
https://play.google.com/store/apps/...apk&pcampaignid=APPU_1_TXl1VcrLFoWB8QXozIGIBA
Root Browser:
https://play.google.com/store/apps/...ser&pcampaignid=APPU_1_oXl1VczIG4_s8AX7-YLQCQ
Note: Default Screen Resolution of Xiaomi Mi 3 is 1080x1920FHD @480 DPI, well what we are going to do is Change it into 720x1280HD @320 to improve performance. (Don't worry about getting the icons bigger, the reason why we have to reduce the DPI on the Build.prop is to avoid glitches and make the Icons and UI at the normal size when changing the resolution, because using the Resolution Changer alone will cause some glitches on other apps )
Steps:
1. Open Root Browser; and find /system/build.prop and open it using RB Text Editor.
2. Find ro.sf.lcd_density=480 and change it to 320.
3. Click Save.
4. Open Resolution Changer; Enter 720 Width, 1280 Height, 320 DPI
5. Click Apply and wait for it to change.
6. Click Yes to Confirm and Skip on the next dialog.
7. Now exit the app and Reboot.
After rebooting, you'll see that you've changed the Screen Resolution to FHD>HD. :good:
Congratulation, to prove it do an Antutu Benchmark test and you'll see the difference. :good:
Additional Info:
(OPTIONAL IF YOU'RE USING CUSTOM DPI ON FULL HD)
If you were using a custom DPI on FULL HD for example;
You're using 400 or 380 or 370 on 1080x1920FHD Resolution,
Do these to properly change resolution to avoid getting the UI or Icons Bigger than Normal.
Example;
If you are using 400DPI on 1080x1920FHD.
400÷3=133DPI
400-133=267DPI
so the right DPI that you're going to use would be; 267DPI on 720x1280HD PLEASE, DONT FORGET to CLICK THANKS!
Everything is working almost perfectly. Some icons are larger than they used to be. But that wasn't problem. Real problem is that SwiftKey keyboard didn't scale. So I had to revert back to Google original keyboard to reset resolution back to 1080p

Oh I forgot to write something about Swift Keyboard, Sorry since I used Google Keyboard. but aside from Swiftkey everything is fine :good:
I have done this years ago. Not only CM/AOSP but all rooted phones.
Thanks for putting some guide though. :good::fingers-crossed:

I wrote this guide for those who are confused and experiencing glitches when using the Resolution Changer alone and of course for the beginners
added additional info.
I just noticed. I used 294 DPI for 720x1280

Alright! ?
Initially tried this with MIUI v5, turned out to be very bad. The icons became very large and going to back to native resolution didn't help either. Fortunately I had nandroid backup.
Later I tried it on MIUI 6, it worked!
Some glitches are there:
- On recent apps screen
- camera effects selection screen
- Calender and clock icons turned invisible
- Minor glitches in clock app
Otherwise everything looks good, and performance bump is noticeable. Excited to find out how much it improves battery life.
Thanks for sharing.

No problem
that's why it's for CM/AOSP Based ROM but I'm glad that it worked for you though there are some glitches.
Hi im using a a33 tab with screen dpi 160 and 480x800 resolution. Can I change this to higher resolution and dpi?

You can but, I won't recommend it because it would just stress out the processor and gpu of that low-end tablet, just leave that be.
Better use gl tools
While everyone gets larger icons,i am getting small icons,small screen,and all the app including resolution changer itself says the current settings is 1080x1920 with 320dpi.
Where am i doing it wrong?
I am on cm12 latest nightly.
same problem as Jongla here, running the same CM 12 nightlies. I guess the problem is that resolution changer doesnt change anything after you apply, current settings are kept as FHD res. Maybe try a different app to do it.

thanks buddy, this one works like a charm
cool trick..
It's become blurry, not clear like before
Guys, if you're using a CM rom, just install Xposed and install the App Setting module. Then, you just choose the app, turn on the custom settings, choose the resolution and dpi you want, and the app will run with those defenitions without having to mess with the entire UI on the device...
In Miui You can change Display temperature From Normal To Warm Or Cool
But when using custom rom like Aex or Lineage i can't find that choice
the screen is really warm and white color is almost yellow
please i need any solution for this i want to make the screen contrast cool Like Miui
Thanks i really appreciate your quick answer
Theres color profile option in livedisplay setting on los based roms, use that.
i tried it but it can't make white color looks really white

Use Kernel Auditor app..and if your kernel support kcal you can calibrate the display color profile.
Would You please Explain what is kcal ??????

Its an module for Advanced color control for Qualcomm MDSS 8x10/8x26/8974/8084/8939.. your kernel have to be supported to make fully use of it. check thishttps://forum.xda-developers.com/android/software-hacking/dev-kcal-advanced-color-control-t3032080
The los livedisplay also got manual color calibration option, that should be enough to tinker by your own to get however white you want.

Not really...on livedisplay there are only tweaks for the screen RGB color which is not enough in many situation...in KCAL you have screen value and contrast value and minimum sRGB value those are valuable option to tweak... that's why I've told you...now its up to you.
