The text of the actual program is too small for me, especially the project media box. I tried increasing font of computer but didn’t help. Is there a way to increase text size from the program itself? Thanks!
No, not that I know of ... and there doesn't seem to be a text size setting in VP's internal preferences.
However, if you select the Thumbnails view, you can use CTRL / mouse scroll wheel to increase/decrease the size of the thumbnails but, unfortunately, the size of the text underneath the thumbnails doesn't increase or decrease in size - not here anyway.
You might the 'Adjust high DPI scaling' in "Options> Preferences> Display" or you could adjust the PC's DPI display setting, but that would affect most everything on the PC.. Also try the right-click the VP shortcut and Properties> Compatibility. Click 'Change high DPI settings'. Check-mark the Override high DPI scaling, and choose "System (Enhanced)" in the context menu. This would change the size of toolbar icons as well. I am not aware of a 'perfect' solution.
