Displayport no signal after a few days use

[DTdude]

Hi guys,

 

I just recently bought a new 4K monitor from AOC - AOC U2868PQU. It was working fine with 4k at 60hz on displayport 1.2 for a few days till all of a sudden I came home today and it started showing 'no signal'. I tried a different displayport cable and it showed the same.

 

It doesn't show any display before booting into windows with nothing but a black screen.

 

Right now, I can't help but to use dvi with 1440p at 60hz as a temporary solution until I figure out how to get displayport work again.

 

If any of you out there who has an idea how to fix this, please let me know!!

 

HDMI, DVI all work with the monitor except displayport. I tried everything like disconnecting cable from either end, replugging in, installing monitor driver but to no avail.

 

My specs:

 

Nvidia gtx 780ti

aoc u2868pqu 4K UHD monitor

maximus v gene

Try a different display port cable if at all possible, the problem might just be that the cable is broken in some way. Also if there is more than one displayport port on the graphics card, try the other one, since one could be dead, but not the other.

it may sound like the displayport on the monitor is broken

 

since you have change the cable and still the same result

 

contact AOC and your retailer for RMA

 

GTX780Ti only has one displayport

 

unless you can find a Displayport to HDMI adapter to verify if your GPU output is working
