i have two monitors one trash acer monitor 27" and one msi optix g24c however i just built a new pc and i plugged in my msi and it worked however the resolution was messed up and couldn't be changed so i took the monitor out and plugged in the acer monitor and it was fine but now i can plug in the msi monitor however it will not display anything except the logo and then it says no signal????\
