HDMI to monitor not working

Hey all, I just got an A500, rooted it, flashed bootloader, recovery, custom ROM, all is good. One issue, I did not see anything on point in the Q&A section on this. I have a standard HDMI cable hooked between my laptop and second monitor. I did get a micro HDMI adapter. I pulled the cable from the laptop and plugged it into the tablet. Black screen on the monitor, although the orientation on the tablet does switch. When I pull the cable out of the tablet I do get a "check signal cable" message across the monitor, so it does seem to be "connecting". I've searched every setting on the tablet, there doesn't seem to be anything else I need to do on it. Am I missing something? The monitor is a Samsung SyncMaster 940BW, fwiw. Any guidance would be appreciated.

Which ROM are you using for your tablet? ICS or JB? I have a Sony Bravia and when using ICS ROM, everything worked fine. But for the JB, only video but no sounds on the TV, only sound from tablet. It's a known issue for JB ROM. Is this the first time that you use the HDMI from tablet to TV? If yes, I suggest you check the TV's manual for set up option for HDMI. For my Sony TV, I had to use the remote control to select the input option every time I connect the tablet to TV.

PJ Sports 10/27, yes, JB. Sorry, I did not make it clear that I am trying to plug it into my 2nd monitor, not a TV. So, effectively it's a direct path from the tablet to the monitor. Does that help to clarify?

Usb port

Does mojo have a micro usb port for debugging mode/adb? Also what about official usb drivers for connecting to a windows PC?
Sent from my SM-N900V using XDA Premium 4 mobile app

It doesn't have a micro otg USB port. It has 2 full sized USB ports. a single USB 2.0 and single USB 3.0 port. I'm going to buy a full sized male to male USB cable and try to see if it will work with debugging/adb with that.

You don't need to use USB - connect to M.O.J.O. over the network instead.
(1) <PC> Download Android sdk from Android website
(2) <Mojo> connect ethernet or connect wifi to get a ip address xxx.xxx.xxx.xxx
(3)<Mojo> Settings -> About M.O.J.O. --> Build number ==> click 8 times, Developer options will appear in Settings
(4) <Mojo> Settings -> Enable USB debugging
(5) <PC> Execute in command line==> adb.exe connect xxx.xxx.xxx.xxx
(6) <PC> type adb shell logcat to get debug message

Okay, thank you! That works a lot better for my setup then stringing a usb cable across the room anyways.

It has a micro USB. Right under the hdmi input! So small you missed it!
It accepts up to 128gb cards, must be FAT 32 format.

I believe that is MicroSD above the HDMI.

Thanks for the info!

As a game dev, maybe you have an answer for me, LimeLight + Mojo ? Limelight is an apk being developed by the xda community in the shield forum, it allows pc games to be streamed to android (aside from shield)

Hard to say, I don't see why it wouldn't... I'll have to download it, but don't have an NVIDIA PC card.

Over wireless ADB "adb shell logcat" and "adb reboot bootloader" is working, but loosing connection while reboot. Also no USB detection.

That was expected, that ADB over USB don't work.
I have tried to "adb reboot boot loader", bot the device seems only to reboot to OS.
"adb reboot recovery" loads till the lying Droid with exclamation mark.
One thing, I tinker around is, what's the use of the microUSB port in the battery hole of the controller. Maybe we can use the connection to enter the recovery while booting ?
I have the M.O.J.O since today. I had many Androids (Smartphones/Tablets/TV-Boxes and Sticks and even an OUYA) but this device is from software side a holy overpriced piece of crap.
MAD CATZ, please "leak" some more informations to get root access and other basics. Bring the Play Store in a working condition. Even cheap chinese Androids have more APP access.

I've bought it to use it as a Mediacenter, XBMC is working and Watchever too, but to control the Box from my Smartphone or PC i need root, also to hide the buttons and use apps in fullscreen, for mediacenter its obligatory to have root...
hopefully Mad Catz itself will help us with it, looks like they give pretty good support.

Try asking the live online support guy found on their website.
He's been super helpful for me thus far.

Hi,
Do you know how to connect via adb while the mojo is in fastboot or from the recovery option "apply update from ADB"?
I've tried using USB & eth0 and both not working.. is there a trick to it?

Theirs another method to rooting that doesn't require the male to male cable
Geohot released an app called towelroot v1 which roots it for u just run the app on the mojo and click a few buttons.
Proceed to towelroot.com on the mojo web browser and click the image on the right side of the screen that looks like an upside down y this will download the app to the mojo proceed to install and click the big button in the centre, you now are rooted my friend
I can't remember how it took ages I had massive issues with the male to male method initially. Had to mess around with some terminal commands before my PC would recognise the mojo. but it was so long ago now I can't remember them.
Edit: Just saw how old OP was imagine hes rooted by now

Using Xperia Z2 Tablet as a Secondary display for Windows

How to use your Tablet Z2 or any other android tablet or phone as a secondary display with Windows 7, 8 or 10 (Duplicate or Extend Screen)​Recently my tablet screen got cracked which left me heart broken :crying: . So I decided to use it as a secondary display for my laptop.
It can be done by two ways 1) Using WiFi 2) Using USB Cable
1) Download Kinoni Remote Desktop app for both laptop and your device and connect them both to the same Wifi Network (Internet not required). Simply connect and you will be able to mirror your desktop screen on your device.
2) Download TwomonUSB for both of your devices. Install ADB drivers and on your laptop and remember to turn on USB Debugging Mod on your Android device. Now just open the app after connecting the USB cable and enjoy both mirroring and Extended display on your Android Device.​
This method will work on Windows 7, 8 and 10. I have made a video running windows 10 on my Tablet Z2 with Extended display ​

Very interesting, thanks for the tips..

Update me if you find anything more useful

is the touch surface of the tablet usable as input for windows?

Nook Glowlight Plus USB OTG Keyboard

I managed to get into developer mode on my new NGP, there's no more "build number" as I've seen in several blog posts with the latest update you click on the Nook icon on the About page it takes you to Developer mode. I've been able to install a few apps, but here's what I'd like to do.
I'd like to plug in a USB keyboard and use it to SSH into another machine through my WiFi hotspot to do some HTML/JS/CSS text editing while I'm outdoors (at the pool, the park, etc) as my other laptops/tablets aren't visible at all outdoors with glare. This would be a nice portable solution if I could get it to work, even editing locally on the device through some editor and sending via SFTP would be just fine.
However, I can get my USB OTG cable and USB keyboard to work on my Samsung J3 phone just fine, but not on my NGP it does nothing when plugged in, keyboard caps lock doesn't activate. Is there a way to get it to work, and does it require rooting the NGP? I haven't rooted the device yet.

As a workaround I put a VNC client on it so I can access my other devices and do the typing from there, that way I can use my RPI3 as the system with a keyboard on battery power and do some Python (Django)/NodeJS/ReactJS from the NGP using it as a monitor outdoors, but if I issue the following commands via adb to rotate into landscape mode I lose input on the NGP and have to reboot:
adb shell settings put system accelerometer_rotation 0
adb shell settings put system user_rotation 1
Any ideas?

I believe I looked at this once.
At least one of the problems is that the ID pin on the micro USB connector is not connected through to the processor.
B&N has never shown any interest in putting Bluetooth in a Nook.
We'll have to see if the latest "Nook Glowlight 3" will have either OTG or BT.

MXQ PRO 4K TV BOX - No remote and No Display

Hi I need some help please , I recieved the tv box from a friend with no remote. I plug in adaptor as well as usb to pc to power it up. There is blue light on tv box but no display on hdmi or av input. Any suggestions on how to switch it on or what to do.

It may be possible to control it using a usb keyboard and mouse if you could see the picture and it has the correct drivers. The picture thing sounds like the biggest problem, I would suggest trying different HDMI cables and tv settings. This is highly unlikely, but if by any chance your friend turned on usb debugging before the picture stopped working, there is a tool called scrcpy that can be used with adb that allows you to view your screen on your computer. It’s quite possible that the thing has broken itself, there’s a lot of reviews online about Android TV boxes spontaneously breaking after only a few months of use, sometimes less than that.
