I have both a 21:9 monitor and a projector which I run at 16:9. I used to just switch hdmi cords whenever I wanted to switch over but I just recently installed an hdmi switcher for easier access and cleaner cords. Now when I switch to my projector all is fine, but when I switch back to the 21:9 aspect ratio it stretches the 16:9 ratio to the monitor. Is there any way I could stop it from stretching by having the pc scan the display perhaps? All help is greatly appreciated!
