Default Ubuntu 16.04 Requested size exceeds 3D hardware limit

Hi I've purchased two Coredy UDA-1920 and trying to activate them on Ubunut16.04
with three Dell 19" 1440x900 displays
After installing the drivers when I used the "Display" to turn on 2nd screen, it says
"Requested size exceeds 3D hardware limit of 2048,2048 requesting 2867,900 "
(intel original graphics)
I reduce the graphics to 1024x768 for two displays - I can make it fit.

Then I install compizconfig-settings-manager and try to add a new profile unity-lowgfx-nh to disable Unity 3D. When I reboot and try a 2nd screen, its got problems doesn't work.
The simplest recommendation elsewhere is to turn off
General.Composiste General - uncheck "detect Refresh Rate"
which still doesn't work.

Do you have any recommendations or an app note ? Many thanks
