Lack of windows with distance data and ball distribution on beamer screen on Skytrak

[Rafalt]

I have a problem with display of my beamer – windows with distance data and with ball distribution are missing of screen of my beamer. All data are visible on monitor screen.
I have PC with Win 10 and in graphic card setup I have marked mirroring of PC screen into the beamer.
I think that problem is related to the resolution of my monitor that is higher than beamer.
If I go down with PC monitor resolution all data are visible on PC monitor and beamer screen, but display on PC monitor is using only part of monitor screen.
Has someone idea how to fix it?
I have to add that I had the same problem with old TGC, but on new TGC 2019 all windows with data are visible on booth monitor and beamer Screens.

Is the beamer you mention a projector? If so, have you perhaps used its setting to move the image on your screen (shift left/right, zoom, etc)? My projector allows me to move the image a small amount, and if I move it past this amount the content of the screen gets clipped and is not visible.

Yes I have projector Optoma. Today I was trying different changes in graphics card setup. Now I see that part of left and right part of monitor screen was not visible on projector screen. Regarding projector setup I made some changes, so now all monitor screen is visible on projected screen, but now part of screen is not covered by projected picture from computer. Despite of 4:3 screen setup in projector.
