I have an ASUS VG248 as my primary display hooked up with display port, and a VE248 as my second with HDMI. Everything was running fine last night, but when I turn on my computer today my main screen isn't displaying an output. I get the asus logo just from turning on the monitor, but nothing from the computer. I tried restarting multiple times, tried flipping the cable around, but still nothing. It works with HDMI though. My second display also works with the display port cable. Is the display port on my primary screen just dead or am I missing anything? Plz help,I want to go back to my 144hz again.
