I have a freshly installed Windows 10 PRO system and MS Office Home&Business 2019. I use a 4K monitor on an Nvidia GeForce GTX 750Ti graphics card (I downloaded the latest drivers from Nvidia).
My problem is that Office programs can start extremely small. That is especially the case with "new mail window" in Outlook. See print screen below:
The window is actually so small that I can hardly locate on the Desktop and change it's size. It's similar with other programs*, but not as severe as is the case with Outlook's New message window.
Each program I open it feels like the window should be bigger (and also it was bigger when I last used the program). Sometimes even when my monitor goes to sleep (and Windows is locked) the windows of the open programs are smaller when I log back in.
The problem is really frustrating (it's my work computer), because I spent 10% of my computer time resizing windows.
What could be the problem?
*I'm experiencing similar behaviour on my home computer (Windows Home, also 4K monitor), but I do not have Office installed so the problem is less severe...
**I do lot of remote deskop connecting with above mentioned computers (from "home" to "work"), if this is in any way relevant ?
