U3014, Will not wake from sleep with DisplayPort 1.2 enabled Intel HD Graphics 5000 3 different PCs

We never tested the NUC. The ThinkPad and SP3 must be connected to their respective power cord and AC adapter. I have my doubts that any of these three can drive two 30" monitors via DP chaining. Checking with the team.

Chris- Thanks for the response. Both the Thinkpad and SP3 are always plugged up during my tests. I also want to add that if I disconnect my U3011 and use the U3014 as a standalone monitor I experience the same results with DP 1.2 enabled. Monitor goes into a deep sleep and will only resume via power cycle.

Sounds defective to me.

Based on total sold versus returns, no.

Well just to update this thread. I have opened a case with Dell Support and they have escalated this issue to a higher support level I guess. We'll see what they come back with. I'll keep the forum posted.

UPDATE: I received the replacement monitor which is rev A03 and I still have this issue. The other monitor was rev A05 and the one before that was A04. Is this another Dell manufacturing issue?

I asked Dell support to test my setup in their lab and they claimed they didn't have any PC with an Intel HD Graphics 5000 in it. (Pretty hard to believe)

So I asked them to test it on whatever they had and nothing, "except we'll replace the monitor". I guess it's easier to resolve an issue with an RMA instead of a RCA (Root Cause Analysis); Hey, that's what they have us Forum members for, right?

Lastly, the support experience was the worst I have ever encountered. Slow, inefficient and frustrating. After 3 support engineers and 2 managers, and being asked the same questions over and over again, oh, not to mention the 3+ week support cycle, I finally got a monitor and it still doesn't work.

Based on some of the answers I've seen in these forums and others on the net, the best approach is to keep RMA'ing the monitors until you get on that works. Hmmm, that's a very interesting business and support model. What happened to QA and thorough testing? Reading the customers' troubleshooting steps and then trying to replicate in a lab? Oh wait, what am I thinking...How dare I expect that kind of accountability and support. Just waste the time of folks who are spending $1K+ for a product.

I guess if you can afford a $1k+ product that must = you have time to blow spinning cycles RMA'ing monitors.

I would love to hear from others who are experiencing this DisplayPort 1.2 issue. Also, I did order a third mDP to DP cable from Amazon to test with. I went to displayport.org to see what cables they recommended and ordered one. I'll report back when I've received and tested it.

Forgot to mention that It also did the same on my old WIn 7 PC - new PC is Win 10. So that's 2 different PC's, 2 different cables. I didn't report it before as I thought it may have been my PC, now I wish I had earlier.

I have the same issue with my 3014. It is on a it's 2nd PC now - brand new skylake 6700k, Nvidia GTX 980, 64Gb ram - will not wake up. Over an hour on hold the other day to get nowhere with support. I'm guessing this monitor doesn't properly support DP 1.2, so as per your suggestion I have set to 1.1 and will see if that helps. I have had to remove the daisy chain and buy extra cables. Very poor. How have you got on since May? I will call Dell and ask for a replacement.

My setup is actually working now. It was the intel NUC that was the issue; so I got rid of the NUC. I am now using a standard desktop with an Intel HD Graphics 4400 on an Intel core i3-4150 CPU. I am also using a DP 1.2 cable that connects to my PC using the standard DP connector and to the 3014's mini DP. I then daisy chain using a DP to DP on my U3011 and everything works like a charm. Make sure you have the latest drivers installed as this caused an issue for me in Windows 10. Here is the cable displayport.org recommended: www.amazon.com/.../B00A7R9I22;redirect=true&ref_=oh_aui_search_detailpage

Also, the Dell tech told me that the DP to Mini-DP cable that comes with the monitor is a DP 1.2 cable. I hope this helps and keep us posted on your progress.
