I would like to use a dual monitor setting with a television as second monitor. Everything used to work well on Ubuntu. With Cinnamon Mint, I needed to install proprietary nVidia drivers to get HDMI working, but it is not enough. After plugging the HDMI the television correctly display its resolution 1920x1080 (=TV knows which resolution the computer selected), but wallpaper and all windows are narrowed. But when I check the setting in xrandr, display manager or nVidia server settings everything looks OK. Here is for example xrandr output:
Code: Select all
