470.182 graphics driver for Linux

I have installed previous versions of the 470xx driver in xubuntu with a GT710 card and switched to the 4K modes 3840x2160 and 2560x1440. The latest version 470.182 selects 1920x1080 at bootup as prefered and highest possible mode with the same card. Now this is enoying. I purchased 2 GT710 cards to work in 4K modes as I have mostly 6 large application windows open for FPGA development.
I know it is possible with the GT710 card and the 4K monitor(a Philips 276E). Can anyone help me with this problem ? I would appreciate it a lot.
Thanks in advacnce.
