[Q] How to turn ON screen when conencted to HDMI - Android Q&A, Help & Troubleshooting

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.

[Q] Control from PC

Hi all,
I've the following problem. I have the tablet (Coby Kyros mid1024) with broken and totally unfunctional touchscreen, so it means that I can do nothing with it. The LCD is working well...
I can't turn on WiFi, Bluetooth, turn on the debug mode...rooting...anything.
I've spent all the day by looking for the touchscreen replacement but with no luck But,
what I need by now - Is there any possibility (boot it from the SD card or something like that) to go over the lock/unlock screen and to get remote control of the tablet by the PC (through mini USB, for example)?
My aim is to turn off the lock screen after rebooting and to get the possibility to control the tablet by mouse over bluetooth or USB. But for this I need to turn off the lock screen first and to setup the bluetooth or USB...I thing...
Thank you for any help...

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:

miracast and android

so I recently bought a Blaupunkt 50" smart tv that also supports miracast and I've been trying to get it to mirror the screen of one of my android devices.
I have a LG L bello (D331) on android 4.4.2 that doesn't have the option to wirelesly connect
and I also have an F&U 9" tablet (ETB9544) running on android 4.2.2 and it does have the option of wireless display!
my tablet sees the tv as available to connect and it does but as soon as the image is projected on the tv,the image freezes.
the tablet continues working as usual but the tv keeps displaying the image the tablet had when it connected and after a while it just disconnects alltogether.
if I try again to connect them,the tv tells me to input a code on my tablet but no message pops up on my tablet in order to do so and the tablet just says "connecting" till it fails and stops.
if I restart the tablet,the same thing happens....first it connects with the screen frozen and then it doesn't connect at all.
none of my devices are rooted.
could anyone help with this miracast thing?
I'm so close it hurts!

TV shows "chromecast..." on first time setup at the bottom of the screen

I bought a Chromecast device. When I tried to setup it, it showed "chromecast..." at the bottom of the screen and after about 3-5 seconds it goes back to the No Signal screen. The Chromecast is connected to a MINI HDMI2AV Adapter that is connected to the RCA port on my TV. Is there a way to fix it?

Hi, its possible to turn off phone screen when hdmi/miracast is connected? best without root.
Try flipping the phone over so it's face down on a table/surface?
I do not know if that works for sure, but it is what I do when I connect mine via miracast.
