I'm considering getting an ASUS MB169B+ portable monitor to use with my Shield Tablet. This monitor has only USB DisplayLink as an input.
I know this works with an Android + USB OTG Y splitter + power bank battery for monitor power source as per this thread here using an Xperia Z5:
http://forum.xda-developers.com/z5-premium/help/xperia-z5-premium-support-usb-monitors-t3303060/
The Android device requires an app to output to DisplayLink and will also be stuck in landscape unless you manually change it.
Has anyone done this with an Nvidia Shield Tablet & can you think of any pitfalls I might encounter along the way if I tried this with our device?
Cheers!
I would love to know the answer too, if you have obtained any info elsewhere would you please post a follow up? Looks really nice and with a very thin laptop bag that could hold both the monitor and the shield it would be plenty portable. You mentioned the Y cable with a power bank; a. Does the stock kernel support 'Y' cable charging and - b. If so would using a power bank be any different than directly to the wall or similar? I am currently using a Kali NH kernel which is supposed to support Y charging but I haven't had any luck.

Hi, im looking at the posibility of installing one of these into the dash of my Jaguar XK8 to use for GPS, media playback, OBD etc. Most of it shound be relatively straightforward looking around the forums.
Sound wise I can link to my head units auxilary input.
GPS looks possible using a bluetooth GPS.
OBD again using a bluetooth device in conjuction with Torque in android.
Possible link up for reversing camera if i use a USB tv tuner maybe?
Power wise i can use a car charger hidden away inside the dash. Question though, will the unit automatically power on if it receives an AC charge in the case where the battery has run flat and the device has turned off beyond being in a suspend mode?
Is pretty much everything controllable on screen? My current plan would leave no access to hard buttons.
USB host - can I connect to a laptop hard drive using a usb to ide adapter? Just thinking for my 100gb media hard disc.
Think that is most of the stuff covered really.

Yes, root your tablet, use any by linux kernel supported device and some development skills and you're ready to go. idk a out-of-the-box solution.

I got my A101 just for development stuff and put the charger in a power strip with a switch. when I turn the power strip on, the A101 just starts up

the only button would be the power button for shutdown or reboot or the volume control. you would have to have a widget or an app for volume control.

yesno, depends on how much power the harddisc draws. but if you like to attach a camera or livetv adapter as well you have to use an powered usb hub anyway
Wow, thanks for your response... looks like it will do anything that i originally wanted really, which is good news!
Im looking at maybe getting a 7 inch archos - what has prompted this is that I just made the move to android from a windows mobile and so far im dead impressed with it. I also previously had a full windows PC in a car that was unfortunately damaged. Im just looking at fitting something into my replacement car and i thought that a full windows PC is less ideal than an android machine.
I still have my old USB GPS device, which I believe has linux drivers - am I right in saying that if it has linux drivers then it may be possible to get it working under android?
For the most part i cant see the lack of hard keys being a problem. Volume up / volume down will be taken care of by my head unit - so i can set and forget the volume (should be able to set it on screen initially yeah?). Reboot can be handled on screen as well - so far I havent experienced android crashing or freezing, but is this something that tends to happen? If so i guess that will be my biggest problem point.
Also - this is a real long shot - does anyone know if the Archos 70 IT's that are brought as 8gb still have internal laptop hard drive connectors - if so i can just drop in an internal hard drive rather than use usb host.
After having a look at units in store I decided to go with the G9 Archos 80. So far im liking it a lot, its speedy, has a full size usb port on the back which allows me to access my laptop hard drive via a USB -> ide adapter and turns on as soon as it gets power - and has working sat nav. 90% of my goals are already met - just needs some soft finessing and installation in car. Just hoping someone roots the thing soon so I can get her to shutdown / reboot via an app.

I thought I'd throw this out here to whoever is interested in a similar install.
It's been a long while trying to figure out how to get my nexus 10 working otg without draining the battery. So, what I did was eliminate the battery all together and run it with a regulated power supply soldered to the positive and negative pins inside where the battery clip would normally go. Everything ran smooth without any errors whatsoever, then came time to test it all out by plugging the otg cable. what do you know, it worked flawlessly.
I'm able to run a usb hub with 3 flash sticks and 1 ssd hd. Hub must be powered separate with the power plug. This is a perfect setup for my situation since the tablet is installed in my truck and I wasn't too happy with the idea of having a lithium battery inside on hot summer days.
I'm pretty sure this method could even work while keeping the battery installed inside connecting the leads to a double throw relay along with a separate plug that would separate the two power sources.
Testing also passed while plugging it to the pc foe file access and debugging mode.
Hope this helps some people. Don't be shy if you need to ask any questions on this project.
Later
A pc usb port puts out 5v 500ma wich barely keeps the Nexus10 battery level
The ac charger puts out 5v 2amps
I hope your power supply is putting out same amps..

Hello Asylum,
I'm indeed interested in your setup, since OTG+charging is not possible with traditional methods (even pogo cable doesn't work along with OTG).
If I clearly understood, you opened your nexus, removed the battery and directly soldered cables + and - ?
Is it a complex operation ? (in particular to open the nexus and close it without tearing it down).
Do you have a photo of your installation ?
Thank you for your help :cyclops:

I'm also interested in this setup and would love to see pics!
Not to sound like a d1ck or anything, but I have a alternative. Just make a otg cable with a male and female USB ends and just hook up the male end to power lines. Them you can just use a regular USB wallwart to profile power to your drive.
I used this method to run a 1tb external HDD.
Can the USB otg and HDMI be used at the same time?
My situation now is that I have the Moga Pro Power that I picked up at the pawn shop for $40
Noticed that it has quite a bit of lag using the A-mode, and still a noticeable amount of lag in B-mode, approximately 100ms.
So I'm wondering if it's possible to connect a wired controller via USB otg, and if that might have less input lag.
I'm also curious if I can output to HDMI while connected to a wired USB controller.
If I could create like a docking station on my TV that turns my phone into a mean little media station/console, that would be completely badass.
I saw this adapter on Amazon and eBay, it connects to the phone's microusb on one end, and has ports for HDMI, SD, Micro-SD, USB, and a Micro-usb for powering the phone and any attached USB device at the same time. You can find it by searching "otg slimport" on Amazon or eBay.. Selling for under $13 on eBay. Unfortunately, the same product on Amazon has only a 2 star rating. Reviews saying the charging port isn't working as advertised, and HDMI connection is touchy, and certain TVs are incompatible. So it looks like a no-go. China will manufacture and sell just about any hodgepodge of wires and plastic they think consumers will buy, that doesn't mean it will work.
So now I'm wondering if this sort of function is even possible, and if so, is there a product available that can provide it, and if there is no product like that, can somebody please make it?
So I did a bit of research, and it seems there's definitely some technical limitations as far as charging the phone wile in "host" mode. This means that while connected to USB OTG, the circuitry that is normally used to charge the phone, is used to supply power to the attached USB devices. I found a site that has a modified kernel for the Nexus 7 that enables charging the phone while connected to devices via OTG. https://mehrvarz.github.io/usb-host-mode-power-management-nexus7/
Maybe this could be implemented in the V10
I bought this monitor a while ago and it works fine with a laptop that supports Displayport and power over USB type C alt-mode. I read it worked with some earlier galaxy S phones but I can't get it to work with my S9+. The monitor turns on and I get garbled video. Has anyone got this type of setup to work. I've tried searching for a dock/hub that supports USB C alt-mode (DP and power) in and out to another USB C for the monitor but also have a power delivery port - thinking maybe the S9+ isn't providing enough power but also to not drain my S9+ really quickly. Does such a hub/dock/cable exist?
Hi guys, looking for some help here. My goal is to use a tablet with a seek thermal USB camera plugged into the charging port. It's going to be mounted in a semi-permanent location and running non stop, so I'll need to keep power to the tablet at all times. Is there a solution for this? Is there a way to plug power into the charging port while also allowing the OTG item (Seek Thermal) to work simultaneously? I've looked at some connectors on Amazon but it's very unclear if they will only Power the OTG item but not charged the tablet or both. I thought about using inductive charging for the tablet, but I'm failing to find any tablet that has an inductive coil built-in.
I'm going to purchase a new tablet for this so I'm open to whatever model works. Right now the Seek Thermal is a micro USB connection but I have a micro USB to USB-C connector just in case the new tablet uses a USB-C connection.
Thanks so much in advance!
