I want to use my external monitor's resolution fully (2560x1440) with a USB display adapter for my laptop. I have one with Windows drivers, are there any adapter with linux / Ubuntu drivers that can give me full resolution?

I am thinking of something like my current USB to DisplayPort adapter.

HDMI only gives 1920x1200 (am using arandr to achieve this easily), and my laptop haven't got displayport. But I know that the graphic card can deliver 2560x1440 digitally or through an USB adapter.

The question is a year old, but the topic may still be of interest (March 2014): Official support from DisplayLink (one of the chipset manufacturers) is still disappointing (to say the least, see displaylinklinuxdriver.wordpress.com ).<br> Still the posting below from one device manufacturer summarizes current progress and deficiencies of the open source hackers' efforts. plugable.com/2014/03/06/… HTH –  Bernie Mar 25 at 12:43
Ubuntu 14.04 supports it. –  Dishank Jul 27 at 4:29

Unfortunately Linux support of these USB display adaptors isn't really available on a usable scale... I have three of these devices and am forced to use them under Windows.

I guess you could run a virtual machine in Windows and do it that way, but that will likely slow your machine down somewhat :-(

I check Google every now and then for updates on this as I'm very keen to see this functionality in Linux, too!


Found this link, in case you want to give it a whirl

Right now, on Ubuntu 14.04, my Accell DisplayLink compatible adapter just works. It didn't work on 13.10.

Specs of this adapter: http://www.accellcables.com/J130B-001B.html

It seems a little slow on effects, I think that is because of being USB 2, and no acceleration? Anyway I got rid of the effects and works ok
