I'm creating an Android Things device using a Raspberry Pi 3, which will be connected to monitor. The monitor should be on all of the time, but I'd like a way to "turn off" the device (turning off the HDMI output so that the monitor can go to low-power standby mode) so that I can turn the device on and off remotely or with a timer, rather than having to manually push the monitor's power button.
Is there a way to control the Raspberry Pi's HDMI output (turn the display on or off) in an Android Things project?

Please apart from the 7" LCD touch screen, which other lcd screen can work with raspberry pi using windows iot core operating system
It is recommended to use the screen device which is listed in the Hardware compatibility list. As mentioned in the document, this list is not exhaustive. There are many other peripherals not listed on this page that are compatible with Windows 10 IoT Core. You may try with other screen, maybe it is also compatible. If you just want to use a display screen without touch input, in general the screen with HDMI interface is usable.
I have a Raspberry Pi 3 and a 7 inch HDMI Display monitor 800 by 480 resolution. When I connect the Raspberry Pi to the TV monitor by HDMI port, it works fine, but when I connect the Raspberry Pi to the 7 inch HDMI Display, the screen stays black. I have tried changing the Raspberry Pi screen resolution and multiple different settings, but nothing makes it work. Is there any way I can get this to work? Could I test to see if the monitor is even functional?
I recently discovered that part of the HDMI monitor depends on the touch screen USB and Micro USB being in as well as an HDMI port. Once I plugged this in, it received enough power to show the something on the screen.
I am trying to connect my drone M210 RTK to DJI assistant 2, but when i connect my drone to the computer, nothing happen.
I have switched on the drone and put the button on the good configuration to connect to a computer by USB cable. I have also made both RTK and M210 firmware update using the remote controller and the DJI GO 4 App.
So here is my problem : How to do to make the M210 RTK available in Dji assistant 2 so i can enable the API.
A few more things to check for you:
Are you using the USB cable that came with the Aircraft?
Are you using DJI Assistant 2 v1.1.8+?
Is the switch on the back to the aircraft to the computer sign? (switch all the way to the left) page 41 in the manual
Did you try to reboot your computer. Assistant works with a background binary which establishes the communication with the aircraft, on rare occasions it freezes, you can kill the process but rebooting is easier.
Did you try re-pluging the USB cable after power on and switch to computer mode?
Can you access the RTK from assistant (usb switch on RTK)?
On a newer Mac, it appears that OS X treats the 'microphone' as a special device. When no headset is attached, it uses the "internal mic". When I add a headset it transparently switches over to the headset mic (in this case from an iPhone headset).
Is there any way (low-level code perhaps?) I can have it record from the internal mic AND the headphone mic concurrently? I have an application where this is essential.
I could probably use a USB mic instead of the headset, then they would be two separate devices - but I'd like to support headset style devices (or any line-in input) as well.
I have a dual monitor setup,
1: a computer monitor connected via vga
2: a samsung lcd tv conntected via dvi->hdim cable
Until yesterday, this setup was working just fine. Today when I booted windows 7, the bios & windows loading ... screen shows up fine on my lcd tv
however, when windows loads and shows my desktop, my TV goes blank, and I only get the desktop on my computer monitor.
When I go to "screen resolution" and "detect", I only see my computer monitor listed.
As far as I know, no new display drivers were installed, I am using nvadia gt300.
Also, since the bios/welcome screen does show up on my TV, I can root out the tv/cable being faulty.
has anyone encountered something similar before ?
I had exactly the same problem. I de- and reinstalled drivers, I deinstalled the 11/18 Windows Update, I turned my monitor off and on again at least a dozen times as did I unplug and replug the HDMI cable - nothing worked.
Then, in an act of despair, I unplugged my monitor's power cable, replugged it and.... here we go again!
HTH!
