I use TightVNC Viewer under Windows 10 Pro x64 22H2 as a console into two Macintoshes. My monitors are 1080x1920, My MacBookPro (MBP1278 MacOS 10.13.06) has a 1280x800 LCD. The TightVNC windows is also 1280x800. My MacPro (A1481 MacOS 13.2) is headless without any attached monitor. The TightVNC window is only 1024x768.
