Hi. So was on my machine earlier today, no worries. Working as normal. Come home from work my wife says it's not working. So the machine is on, just no display port signal. Turn PC off swap it out for an HDMI turn it back on and get a signal for it. Turn it off plus the display port cable- no signal. Monitor is an Asus VG248. Nice but I need to upgrade. My graphics card is an Asus ROG Strix GTX 1080. Any thoughts on what I should check next. Possible my 6 or 3 year old were in pushing buttons when no one was looking.
