sometimes give the wrong DPI
Laptop with 4k Boot, connect to dock(disconnet primary 4k and connect 2k display)
then GetDeviceCaps deliver 192 DPI (only 96 DPI Monitor connected)

Solution:
change GetDeviceCaps to ...

I Use Repeater with encryption plugin and password -> no Warning

One Solution:
click Thrust and write this to "IP".vnc File

FullScreenTitleBar

Resolved (Only with Multimonitor with different DPI)
add "::SetWindowRgn" after DPI change

and save hLastMonitor TitleBar on wrong Monitor

i hope the last changes from me :)

Next

changed files in my Onedrive

the size of the FullScreenTitleBar changes with DPI change

I found the Bug
Send SendFullFramebufferUpdateRequest On DPI change before running -> empty picture
I add Autoscaling even in the old Options Dialog

wait with release, i found a problem

merge with git code
Now Autosize scale is OK (no Border, biggest possible window)

Faster and better result for other then 100,200,300% is to use "scale to window" (directX)
Autosize is working with directX in window mode too.

toDo
keep aspect ratio for Fullscreen in directX (Only if Autosize?)

New Option:
