18.04 on 1st boot Display Port signal lost

Asked by Floyd Williams on 2019-09-03

18.04.2    Load from CD   select Try: runs perfect Asus 28" PB287Q connected
thru Display Port.

Loads with 3840x2160

In settings: changed to 2560x1440

Run xrandr -q

3840x2160 with 30 refresh

2560x1440 with 60 refresh

Installed on Hard Drive

On 1st boot the Display Port signal is lost -I think that the 30 refresh
might be getting over written with 60

16.04 will load & work perfect

This 18.04 install will boot in a system with a 24" monitor

xrandr -q

1920x1080  60.00*

Down Loaded 18.04 02  re-installed and updated

I need help getting 2560x1440 60  &  3840x2160 30 in the setting
