Hello all!

As many friends helped here and installed the most updated open core 0.5.7 and Catalina.
I found the display issue and I am not sure it is related to which party, so I open a new thread to discuss:

My main display is LG 34WK95U (5120X2160px) connected with Display port 1.4 with RX580, Secondary monitor is Asus PB278 (2560x1440).
I am using switchResX to make the HIDPI work and desktop scaled bigger than 2560X1440px. I need to wider workspace but UI is not very small.

Currently is set as 3200x1350px HIDPI 60Hz in switchresX.
The workspace and picture quality can make prefect for me. only con is I cannot enable HDR in 60HZ.
HDR can only work in HIDIP 30Hz or 60HZ on lower or equal 2560x1080P HIDPI.

Now the problem is that every time when I have issue after booted up, the LG monitor will be in 3200x1350px HIDPI in 30HZ. 60Hz option disappear.

When I shut down LG and power on, click switchRes X detect the monitor, 3200x1350px HIDPI 60Hz will appear again.

After I have changed to 3200x1350px HIDPI 60Hz. The mouse cursor pointing position is all shifted.
As I guess the situation like the desktop UI position is 6400x1700px but the screen display is scale up to 3200x1350px. I never point to a correct position even you see and point to icon...

If I power off the monitor once more and Power up it. Everything will become normal totally...

Anyone know which party may case this situation?

It can work when I menu do above process but I worry the power button will dead very fast when I need to switch on off so much every time when boot.

What is the UI and Resolution I have set right now. It is sharp and enough work space for me.
Right now when I boot to Catalina I need power on two times to make the system have 60Hz option and the cursor click in right position (UI and resolution position match)...
