I am trying to create a single chrome app to display(by using 3840x1080 resolution) on both monitors.
when I try to move a window, from one monitor to other, I am able to see only half of the window on one screen. Is there any settings to make it work like extended monitors
This was apparently a limitation of Chrome OS.
Keyword was: this bug is marked as Verified (fixed) in May. However, see this comment:
Please note that this feature was developed for specific enterprise use case, and will always be behind a flag. In other words, this will not be on by default for general use.
You can enable it using about:flags starting from M44 though.
So, to use this, you apparently need to set the "Enable unified desktop mode" flag in chrome://flags/
. I can't confirm since I don't have a Chrome OS device to test.
