[Q] How to turn ON screen when conencted to HDMI

Repostng from http://forum.xda-developers.com/general/xda-assist/how-to-screen-conencted-to-hdmi-t3034840
I recently bought Isun 407 3G tablet ( MTK 8377) and connected to my TV using HDMI cable.
When connecting, The Screen automatically turns OFF. I need the screen to stay ON.
Turning off the screen while playing videos is alright. but I need to do google search while connected.
The tablet runs on Android 4.1.1 (Jelly Bean).
On searching there are ways to turn off the screen but i need the inverse.
Pls help.
Update: I tried service to call screen wake up when the HDMI cable is connected.
HDMI connection is received properly in broadcast receiver where as the display is not turned on.

Avin Avent 2

I've recent purchased the AVIN AVENT 2 with 4.1.1 Jelly Bean and just wanted to know if anyone has been able to root the device? I'm not sure if it's just my system but it appears to be as buggy as hell, constantly flickering screen especially when my phone is connected via bluetooth but also when I turn the bluetooth off my phone and disable the wifi on the Avin the screen still flickers with the internet usb dongle. When the screen starts flickering you literally have to wait for it to stop before you can use any function on the device. The supplier suggested returning the item back to China under the warranty but having to pay to send it back sucks somewhat so I'm holding out for an alternative solution or a fix. He mentioned that my 2.4GHz Wireless Backup / Reverse Camera Video Transmitter which is connected to the devise could be what's causing the flickering and suggest I disconnect this to see, I haven't had time as yet so maybe one the weekend.
If anyone knows if this device can be rooted so I can tweak some settings to that would be great:good:

How to mirror phone screen to laptop (with broken phone screen)

I got a s3 with a broken screen completely shattered, no light, no touch response etc. but the sounds and notification lights work, i can connect with usb as a media device i can access internal sd...
my question is is there any way i can mirror the screen to my computer via usb without doing anything on the phone because as i said the screen completely gone, maybe with adb or something?? i'm interested in how i can control the phone through the pc, like how asus pc link does it, if anyone can give me any pointers on further reading it would be much appreciated... i don't even know if samsung has such a function..
also i would like it if whenever i connect the usb the phone screen would pop up on the pc, are there any tools that do this?
ps: i heard about hdmi adapter but it doesnt let you control or click on the screen right?

Bluetooth always ON

Is there any way to get the bluetooth always on when i switch On the phone? It is very useful the phone to be able to connect to the car or to my Xiaomi mi band, without having to turn Bluetooth On all the mornings (i use to power off the phone at night).
When I turn ON the phone, it always boots with bluetooth switched OFF
Yes it disables all hardware when shut down. U have to re enable them on each boot

Access tablet after screen has shattered

Hello everyone
So last week the kids shattered my screen. Part of it still worked right after but now i got no display at all. I connected to an external display via a docking station and a simple usb-c to HDMI adapter. I get the screen to come up but its simply a gray screen with a lock on it and the time. Does anyone know how to get to the unlock screen so i can try and pull all my data off the tablet
If it's the data you want, why don't you connect it with usb in a pc. It will see it (probably if you had connect it at past. Otherwise it may need to preen in screen to give access, which you probably can't do..), as a hard disk and copy whatever can be copied.
If you can install a usb mouse when you connect it with a hdmi you could press the screen with the mouse also..
