P2715Q, DP/mDP handshake problems?
Although there is another topic called the same thing, Dell won't let me post a reply on the old forum thread.
I am running my Dell P2715Q at 1920x1080 res, 60 Hrtz, and I often have the screen go blank, even while I am using the monitor, and had just ctrl-esc out of a full screen game. This happens about 2-3 times a week.
Sometimes I can't turn off the monitor, the monitor just ignores the power button. Other times I can't turn on the monitor.
Every problem like this can not be fixed in any way - even rebooting or turning off the computer. But, they are all fixed when I unplug the monitor and plug it back in. This is now very annoying. Is there some fix that can be done?
Also, the cord that came with the monitor never worked, and I had to buy a new cord to get a working one (cord connects monitor to video card).

Did you read through this? If yes, per the warranty, you may initiate a monitor exchange. Test the replacement before sending any monitor back to Dell. If the replacement does not have the issue, keep it and send us the original. If the replacement has the SAME issue, the monitors were not at fault. Send the replacement back to Dell. Look to the computer operating system drivers or hardware as the culprit.

I have now read the link you provided.
My system supports DP version 1.2 because I can use 3840x2160 @ 60hz.
I have confirmed MST is off.
I have the newest stable video drivers.
Considering how many people report unplugging and plugging in the monitor fixes problems, I doubt I have a monitor that can be fixed by a replacement, unless the monitor is different from what I have now.
Some examples of unplugging reports are from:
en.community.dell.com/.../19629524
en.community.dell.com/.../19621224
en.community.dell.com/.../19655104
en.community.dell.com/.../19623175
en.community.dell.com/.../19650599
www.bhphotovideo.com/.../dell_p2715q_27_3840x2160_dh.html
Etc. Considering how many people have posted this problem here in your forums (And I originally found out about the fix elsewhere), I feel certain the monitor design is at fault, and not the manufacturing process. If Dell redesigns the monitor to fix the problem, I would be happy for a recall so I can replace this defective design.

There is no recall. What revision is your monitor? (A00, A01)

If troubleshooting cannot resolve the issue and the P2715Q revision is A00, A01, or A02, then Dell Technical Support for your region should setup a used exchange for an A03 revision of the display. A used exchange is the only way to get the A03. For your region, the part number they should order is X24K1.

After studying Google for any reports that REV A03 fixes the problem, I have not yet found any confirmation. I request to see what the revisions changed. I know from other posts you are not given that information, but is there some way I can see it before wasting Dell's and my money for shipping charges at the very least?

I have an A03, have the same problem. I'll be starting a new thread to see if I can get this resolved.

I cannot discuss the actual changes. Per the warranty, Dell pays the shipping back and forth.

VanCityMike states REV A03 has the same problem with the monitor needing to be unplugged every once in a while. I do not know what REV A03 does change, but it seems to not be this problem.

Ok, Excellent. Thank you. I will request a used monitor then with the newer firmware.

Perhaps VanCityMike's is defective. All I know is that A03 fixed this issue for many other users.

I haven't been able to even start the process of getting a new monitor since dell canada is taking its time to put the service number under my name. I can't start the process of a return before that is done.
