Hey guys, I recently purchased a new ASUS PB278Q 1440P monitor to bundle with my EVGA GTX 780 3GB.
Let me first say that I did buy a used one from the amazon warehouse, and I was having this issue where the display port and HDMI would always say NO SIGNAL, from time to time. This made me believe that it was the reason why the previous owner (or it could have just been an open box because it looked brand new) had returned it. So I chatted up amazon, and explained the issue. They refunded me my money, and I placed an order for a brand new one. The new monitor arrived the 15th of this month (July), and everything was working perfectly until it started telling me that the Display port and HDMI had no signal. All the cords were plugged in snug and tight, so I know that couldn't be the problem. But two monitor having the same issue? I'm at the point where I don't know if I should return it, or check with ASUS tech support. I emailed them yesterday morning, and I'm still waiting for a response.
Now, on the 15th, I decided it would be best if I upgraded my 3GB 780 to the newer EVGA GTX 780 with the 6GB of VRAM because of 1440P. I had used the EVGA Step Up program, and the new 6GB model arrived the 22nd (July).
After I upgraded to the 6GB card, I knew that there wasn't a problem with my older 3GB card, because I was still occasionally getting the "NO SIGNAL". That's two different cards being used (GTX 780 3GB and GTX 780 6GB), yet still same issue with the monitor.
So two monitors, and two different graphic cards both displaying "NO SIGNAL" and going into standby mode, makes me think that there is something wrong with this monitor. I absolutely love this monitor, and I really don't want to return it.
Because of the new 6GB card, apparently the NVIDIA drivers don't detect the card unless I'm using 337.50 or above. 337.50 is the beta driver, so I decided to use the 337.88 ( I think that's the newest WHQL). Same issue. Anyways, that shouldn't matter because I still had the problem with the 3GB model.
It seems to tell me "NO SIGNAL" at random times, but today, when I was trying to turn on the NVIDIA ShadowPlay, the monitor went to sleep, and said "NO SIGNAL". It was stuck like that for 15 minutes, and the only way to turn off my computer was to hold the power button down on the case, until it went off. I haven't tried to turn it on yet, but I'm so frustrated with this issue.
I really hope some other people have had this issue and have resolved it. This is the first monitor I've had, so I don't really know how to diagnose it. I'm still waiting on a reply back from ASUS, so hopefully they can tell me something to fix it. But just out of curiosity, does this monitor have different revisions? Maybe I got a bad first version, and maybe they fixed it in a new revision...? I'm asking because I've heard about the Dell U3014 A01 version having problems, but the newer A03 revision had fixed everything.
EDIT- Every time I have to reboot my computer, all of the NVidia drivers and my 780 get disabled. I have to go into device manager and enable it.
