HDMI not working

[gubaguba]

I have a working install using the pine64 touch screen monitor.  I was thinking I might want to use the HDMI output as an occasional option. However if I disconnect the touchscreen I get no signal out on HDMI. It will send a signal with screen connected but only a partial screen. Been a while since I did the install and for personal reason had to shelf working on the project. Does the install only work with the touch screen? Would I need another install to functionally use the HDMI.

Thanks

If ur r using Android
To have booth screens active led and hdmi u need to set in the uEnv file
Lcd on

If u want only hdmi u have to disable Lcd

If u r using Linux
There's no way to use booth at the same time at the moment

OK is that something I can do within the OS on android? It would seem not. Where would that file be located and how does one edit with android? Sorry but new to android platform. Kinda why I got this thing.

Int he ayufan thread of android 7
There's some information about how to edit configurations


The uEnv.txt file is located in the boot partition of th sdcard
Is the portion that shows up when u plug the SD on your pc
U can edit that file
In the latest version 1.8
In the file itself there's the information u need to set your configuration

Just uncomment the line that u want to use or comment it to disable

U comment by adding
# in front of the line u want to use
And uncomment by deleting it

In the newer version of Android there's root acces to apps so u can use any file editor to mod the file form the system
Just go to the root folder of the system and then go to the boot directory

PDT:
If u want to. Use the hdmi and Lcd at the same time u need to start it without the hdmi cable

Attach it after boot

I can open several volumes on my linux laptop. Doing a search for uEnv.txt returns no results. Searching root file within Android OS also return no Boot directory and no uEnv.txt file

Please give full directory path to file such as /dev/boot/uEnv.txt

Using Android 5.1.1 LCD installed

There's no so much flexibility
On that version
Cuz I thought u were talking about the nougat version
Download that one there's more setting to play with and now we have root acces to apps as well
Check the Android 7 thread
