RTX-2070 - Ubuntu 19.04 - laptop - 4K internal screen

When i try to install cuda, the cuda removes the nvidia drivers and install the version 418 of the nvidia drivers. When i reboot, the screen is not in full resolution. I have only 640480…
How can i install CUDA with the latest nvidia drivers 435 or 430?
The latest edid.bin doesn’t works → also 640
480.

I have now installed Ubuntu 18.04 LTS and the drivers, screen and cuda works perfect. So the problem is fully solved.
Many thanks for the support!
