USB Monitor with Chromebook

Reported by, May 31 2014

Issue description

UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.114 Safari/537.36

Steps to reproduce the problem:
1. Not supported

What is the expected behavior?
Unable to connect USB Monitor to Chromebook

What went wrong?
Nothing worked

Did this work before? No 

Chrome version: 35.0.1916.114  Channel: stable
OS Version: OS X 10.7.5
Flash Version: Shockwave Flash 13.0 r0

Would be great to have the ability to use a portable monitor connected by USB with a Chromebook as HDMI is not supported by portable monitors as standard.

Another request for USB monitor support. I can't travel for work with my Chromebook without this feature. 
We are fully integrated into the Google Ecosystem at work, Chromebooks are becoming more popular for the travel folks, but not being able to use thier USB Monitors with them is holding them back. 
Sadly when I bought a chrome book I assumed this would be simple and not an issue at all. I guess I was wrong. Not sure I'll be able to use the Chromebook at all for what I intended.

This is very much needed for the possabuility to work with 2 screens on this laptop. If that is possible this would be a possible laptop for a big part of my organisation.
Yes, please make this happen!!!  This would add some real productivity to the Acer C910 and the Chromebook Pixel as well.  Being mobile has become a pipe-dream for me as I am so used to using dual monitors.  The addition of this functionality would let me be fully mobile again!!!  Please, please, please!!!

Please add USB monitor support for AOC type Model e1649Fwu. This would be most helpful. Thank You!
yes, please add USB monitor support
Any updates?

I would be happy to see this support. I have replaced my Windows laptop with a Chromebook and I can only run one of the two monitors I formerly used. I looked into purchasing a Chrombox but I found that they support only two monitors, which doesn't get me anywhere, given that with my Chromebook I have the laptop screen and one other screen already. I want three!

I 24th this motion.  Need it for business trips and presentations to clients.  Lenovo ThinkVision LT1421 14" Portable USB LED Monitor
I need this so much!!!  This would turn my chromebook from a weekend/end of day casual browsing machine into a full work station for me.  Being able to ditch my bulky company laptop and just use this would make me completely mobile and still 100% productive as I am with my day to day pc.

Why is this not done yet? I need to hook up my 12 aoc usb monitors to my Toshiba  chromebook 2 for a true google cardboardesk immersive  computing experience. cheap surround computing is needed for my survival. Don't murder me by excluding this feature any longer.

Ok, one thing at a time. There are multiple issues being discussed here.

(1) The main issue is USB monitor support - several specific monitor models are mentioned in comments #20, #24, #27
(2) The secondary issue seems to be supporting >= 3 monitors

For (2) it is already possible to physically connect 2 external monitors to Chrome OS and they would be placed in horizontal extended multi-monitor mode, however the UI for multi-monitor configuration is still ongoing (see  bug 467193 ).

For (1) all Chrome and Chrome OS side work for UDL 2.0 ("DisplayLink', 'Universal DisplayLink') are already implemented as of Chrome OS release 45 (see  bug 238785 ) for all Chromebook and Chromebox devices currently running the Freon graphics stack. This includes all Intel-based devices, the Samsung exynos-based devices and the Rockchip based ARM devices.

The only unsupported devices at the moment are the NYAN and its variants (based on NVIDIA Tegra) -- we are still waiting on graphics driver support, see  bug 478339 .

In addition, it is known that the USB monitor can only run in extended desktop mode. There's another bug open ( bug 463560 ) to support mirroring.

Please add details to the bug (with a complete copy & paste from chrome://version, AND the exact USB monitor model #) if your device is not based on NVIDIA Tegra SOC.

I tried an Asus MB168B USB3 external display this morning with my Chromebook Pixel, it didn't work.

Re:#30 Joe - can you briefly describe what happens when you plug in this Asus MB168B monitor? Specifically (1) do you see any error messages / dialog box showing up on your Chromebook Pixel when you plug or unplug the monitor, and (2) do you see anything on the external display at all, whether it is garbled picture, wrong color, or just completely black.

Comment 32 by, Dec 29 2015

1) The Chromebook doesn't react at all, no sounds or pop-ups.

2) The external display flashes once and turns on, but it appears to not be receiving any signal and turns itself off shortly after.

jdufault@ can you take a look since you've been poking at UDL stuff lately?  Feel free to order a display if you need.

Turns out the MB168B is a DisplayLink 3 device. We don't support those.

Comment 35 by, Jan 4 2016

That's unfortunate. It sounds like there are no plans to support that in the future then?

Display over USB using UDL 2.0 currently works. UDL 3.0 support is a WIP.

Merging into  for UDL 3.0 support.
I also just bought an Asus USB monitor MB168B as I can't work for very long on a laptop screen due to eye issues.  I need a larger monitor. Wish I'd known this before I bought a Chromebook, which so far is good in other respects.  Please add  UDL 3.0 support so I can use the Asus monitor, which is perfect for my needs.  THanks.
re #37: Most of Chromebooks do support UDL 3.0 now. What kind of Chromebook do you have?
