Mirroring Display 1 and Display 2 Together
by Lance198 from LinuxQuestions.org on (#6R3S4)
Hello I've been trying to use xrandr to mirror my main monitor to my capture card but haven't been able to.
When Running xrandr --output HDMI-1 --same-as DP-3
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 7 (RRSetScreenSize)
Serial number of failed request: 36
Current serial number in output stream: 37
I Get that and IDK how to fix it
