S2716DG, Wake Up Issue, Disable Monitor Deep Sleep

I am the new owner of a 2716DG Dell Gaming Monitor - but having a strange issue when turning on or restarting computer -
Monitor using DVI (Asus VG248QE) will start up correctly - but the dell monitor will not start up until power cycled or alternatively the mDP - DP cable can be re-seated for the same effect

I have read online about various wake up issues with DisplayPort technology but none specifically with this monitor. Here is the relevant technical information -

* What is the 20 digit alpha-numeric monitor serial number? CN-0NNV54-74261-5AM-0L6Q-A01
* What specific computer model? Self built
* What operating system? Windows 10
* What video card? Nvidia GTX 970
* Video card driver version? 361.75 (Have also tried latest non-beta drivers)
* What video out ports are available on the video card? mDP x 3, HDMI, DVI
* What video out port are you using from the video card to what video in port on the monitor? mDP to DP
* What cable are you using to attach the video card to the monitor? StarTech.com Mini DisplayPort to DisplayPort Adapter Cable - Video/Audio Cable - Mini-DisplayPort (M) - 20 pin DisplayPort (M) - 1.8 m - Latched
Have also tried -
Accell UltraAV Version 1.2 Mini DisplayPort to DisplayPort Cable - White
* What windows power plan? Balanced
* Press the monitor Menu button to open the monitor OSD (On Screen Display). The bottom of that screen should show a resolution. What is listed? 2560x1440, 144Hz G-SYNC Mode
* Was the monitor purchased from Dell or some reseller? Reseller

I'm pretty sure it were already stated in this forum that disabling "Monitor Deep Sleep" in the "Menu" - "Others" solves the problem. Did you already try this?

It appears that you are having boot up issues with the S2716DG? Wake up issues would imply that the computer was on but in some sleep mode? Have you tested all three of the Nvidia GTX 970 mDP out ports? Test without the Asus VG248QE being connected to the Nvidia GTX 970. Have you tried lowering the monitor Hz to 60, then retesting?

I have followed through with EVERY step in the instructions manual, and every step found online.  This monitor still refuses to boot properly with all the necessary drivers, sleep modes deactivated (on the monitor and through windows 10) and every other step that has been prescribed.  As of March 2018 these monitors still do not perform as intended.

I have the same issue as well, i've had this issue since i bought it like 6 months ago. It will happen weekly. 
Still didn't find a workaround, i try to restart my computer everytime. sometime it take 2-3 times restart for it to wake up. Sometimes it wont. I use a HDMI cable to wake it up, then switch it back to DP.... really annoying for an expensive monitor.

Windows 10 // GTX 970 // 2nd monitor is a LG IPS234

Just purchased one of these monitors and facing the same issue. Thought my GPU wasn't working initially, but turns out if i unplug my DP cable and replug it in, it seems to wake the monitor up. But less than ideal, having to pull my computer tower out to reset the cable each time.

Any solution yet, or am I best returning the monitor?

Hi Chris, Thanks for the reply.

I was referring to the monitor waking up from sleep - rather than the PC... I'm not familiar with the normal terms used. 

Have tested with all thee mDP ports and same issue.

Without the VG248QE (DVI) connected the monitor starts up correctly. This leads me to believe that the GPU is not trying to initiate a DisplayPort handshake once it has discovered the primary monitor.

What are your thoughts on this - IS power cycling the monitor initiating the handshake from the monitor side?

I think that the monitor power cycle is pinging the video card which in turn initiates the DP handshake. When both are connected, is the S2716DG primary and VG248QE secondary in the Nvidia Control panel?

I also own this monitor as I purchased it less than 2 weeks ago.

My setup is identical to yours except i'm running a GTX 980Ti.

I've noticed that it has an issue of waking-up after the PC goes into power-saver mode and the monitor goes to sleep.  THIS OCCURS IN BOTH MY WINDOWS 10 AND LINUX MINT 17 ENVIRONMENTS.

I'll step-away for a few minutes and when I return to my PC, the monitor is in sleep and the white power led on the bottom right is slowly blinking.  I'll jiggle the mouse and/or type on the keyboard (which is lit by-the-way) but the monitor won't come-out of it's sleep.  What I've discovered works (i was hitting the reset button on my PC for a while) is pressing on the button closest to the power led light (far-right button).  This wakes-up the monitor and i'm able to go about my business.  

However I don't think it should be working that way.  My Dell U2410 Ultrasharp didn't have this issue before I replaced it with this new Dell.

Yes, the S271DG is listed as Primary in the Nvidia Control panel, with the VG248QE listedd as secondary.

So by pressing the #4 Exit button, the monitor wakes up? Yes, try that and post the results.
