I have a Benq RL2450H monitor. I would like to connect one of my computers (Linux) to the VGA port on the monitor and the other computer (Windows 10) to the HDMI, and switch between them using the mode switch on the side of the monitor. Is that safe to do? Will I hurt the monitor if both computers are on at the same time?
Yes, that is safe to do. That is what is intended with our monitors. You would just need to change the input in the OSD monitor menu.
