Faulty monitor or gpu?

[Diddums x]

Afternoon

I'm hoping you guys can shed a bit of light on this as something seems to have gone but I can't figure out which.

I've ruled out the pc as I still get signal on DVI. The monitor also works fine via HDMI as my ps4 works fine.

It's an R9 290 connected to a Samsung 32D850D. Woth the monitor connected with DP the most I can get out of it is the backlight flickering on and off every two seconds or so. If I unplug the DP whilst the pc is on, Windows makes it's familiar hardware disconnected sound.

Unfortunately I have no other DP devices to hand which I could use to rule out the gpu and the only other gpus I have don't have DP either.

Any ideas?

DP cable might be the problem?.

to clarify, are you using straight DP > DP, or an HDMI/DVI to DP converter?

DP cable might be the problem?.

My initial thought too, I'd try a different cable.

Yes, DP to DP.


It's sorted now, thank goodness and thanks for the replies. It was indeed the cable, JD was correct. First time I've had a cable fail in 31 years!
