After installing Debian 9. Linux operating system I can't connect to my projector. The Display setting item is missing. Please help thanking you in advance
Hello @Daniel Mangwende
You have to know that Linux, even the most "out of the box" Distros are not supporting all drivers out there. ( Even engineers trying their best to keep their distros up to date). Companies that produce hardware usually support only windows and/or MacOS
You have to make a small research about the hardware you want to connect on your Linux PC.
