Hello all,
Maybe one of you will know the answer, I do hope so haha.
If I connect an Android smart tv box (like the MK809IV smart tv stick) to a HDMI display, can I dim the display with the device, like I can dim a phone screen?
The purpose I have is this: Android device running Torque Pro (this app can show car data like revs, speed, turbo pressure, etc. on an Android device) connected to a display by HDMI. The screen will be used in a car, so I want to auto dim the brightness when the ambient light gets darker. I searched for a lot of options to do this with a custom build display with an ambient light sensor, but I thought Macrodroid can help me out too, with dimming the brightness at specific times. This works on my phone, but will it also work on an Android device that has no screen by itself, like a Android stick or Android mini pc?

Is there a way to display your entire phone display through the tv out?
I want to run tomtom on my car display, I would like to know if how to do it.
The TV out does display the entire phone screen
Stock TF700T, unrooted, etc., 4.2.1
Prior to the update, when I connected to TV via HDMI, to watch Netflix movies, the Tablet's display automatically turned off once the movie started playing. Required no action on my part.
Since the update, the display stays on, and I can't see or find any setting that will change this behavior.
The TV display looks great - no system bar at the bottom or anything - but it is obviously a waste of battery power to keep the display on, it puts unwanted light into a darkened room, etc.
Any way to restore the original behavior, which makes so much more sense?
Running on official 4.4.2 firmware.
I found that the screen display is way too dark, very unacceptable. This is very obvious for video playback from every software, e.g. youtube, mxplayer, xbmc, etc.
As I share same hdmi port on my tv with other 5 devices, it is not convenient to adjust tv display back and forth between other 5 devices and this dark-display tv box.
My box is rooted. Is there any way to adjust its gamma, black level, etc. Tried several brightness adjustment apps from store and did not help.
MiniX Forums had a thread covering this, without much of a complete solution. Since they changed their domain to minixforum, the thread either has a different URL or is lost, but google cache exists of the original - http://webcache.googleusercontent.c...reen-too-dark.3631/+&cd=2&hl=en&ct=clnk&gl=uk
Short version is try changing HDMI range on your TV from limited to full. It may help other people to reply if you mention which Android apps you've tried to use (which presumably were adjusting backlight levels on a phone/tablet, rather than the video signal data being sent by your box. As an example, although advertised as only compatible for a couple of Nexus devices, have you tried https://play.google.com/store/apps/details?id=com.teamkang.fauxdisplay&hl=en ? How about https://play.google.com/store/apps/details?id=com.netmanslab.sa&hl=en ?
Thanks a lot for your comprehensive reply.
My LG TV don't have an option for Full-range RGB; however, it has several Picture modes for me to choose. I usually use one of the Picture mode (say, Standard Picture mode) which I already tweaked/calibrated for best display quality.
Some other picture mode on my TV allows me to choose Gamma (high, medium, low), brightness adjustment, and Dark Level (high, low). I tried adjusting those options in combination under another Picture mode and, though not perfect, it gave me a better result.
So when I view other sources (Dune, Appletv, digital tv, satellite tv), I choose the Standard Picture mode; when switching my hdmi selector to this Android box, I have to choose the other Picture mode on my TV. This is good enough for now.
The Screen Adjuster app won't help. I've not tried The Advanced Color&Gamma Control paid app.
Anyway, Android tV box should have gamma/brightness/contrast/sharpness control under its Setting.
Update: tried Advanced Color&Gamma Control app, it allows me to adjust rgb only, no gamma adjustment.
Hi,
I recently bought a Tolino Tab 8 with a Intel Atom Z3735 processor, running on KitKat 4.4.4. Everthing works fine but every time i switch between apps the screen brightness changes depending on the background of the app e.g. when i open twitter (mostly white background) the screen brightness goes up and when i go back to the home screen (black background) the brightness goes down. No matter if i enabled auto dimming in the settings or not. I've read that has something to do with Intels Display Power Saving Technology which is used to extend the battery life of the tab. I tried to edit the build.prop (mentioned here http://forum.xda-developers.com/showpost.php?p=65422943&postcount=1786 ) to turn it off but nothing worked so far. I also tried to find the driver settings itself ( mentioned here https://forums.lenovo.com/t5/Lenovo...Tab-S8-50-Screen-Dimming-Problem/td-p/1873040 ) but could'nt find the right settings.
The Tablet was manufactured by Trekstor if this matters somehow.
Hope you guys can help me to solve it.
I also have a minor bug where i can't change video resolution in the youtube app above 720p even the Display has the resolution of 1920x1200 which i think has something to do with 4.4.4.
Hey everyone,
I would like to present you app that I created to automatically adjust screen brightness. Tested on LG K8, Android 6.0. App is using front camera to determine lighting in smartphone environment. I created it because I recently changed my phone and as it turned out this one does not have light sensor, and that was cumbersome for me (day or so after using phone I faced situation when I was outside, it was very sunny and brightness was set to like 10%. It was impossible to unlock phone because I couldn't see anything on screen even if I tried to cover phone screen from that light, so phone was totally unusable!). I didn't find this kind of app on Google Play so that's why we have this thread.
FEATURES:
- automatically adjusts screen brightness
- automatically turn on device boot
- 5 frequency options
HOW TO USE:
1. Download.
1.1. [6.0+] Give permissions.
2. Choose one of available options (I recommend using medium refresh rate).
MORE INFORMATIONS:
Of course app will be improved. I want to add notification with brightness adjust bar, and improve algorithm that is determining what brightness level will be set.
FREE DOWNLOAD:
App in attachement.

Thats good for device doesnt have light sensor
Great idea... However on my k8 its a bit confused... i tried it in the office during daylight, it was quite dark instead of bright and when i covered the front camera its become bright... maybe you could put some options there to manually adjust intesity levels related to the picture brightness?
Good idea
