I recently build a new computer and bought Asus PB278Q monitor as well. It used to work fine but from last couple of days if I am trying to boot up or resume from screensaver or power saving then the monitor displays the message "DisplayPort No Signal". To fix this problem I have to disconnect and reconnect the DP plug in its back again. I am not using any video card on my Asus P8Z77 motherboard. Can anyone tell me how do I solve this problem? Thank you
