I would like to know, does your monitor have the setting to change it to DP1.1?
NOTE: Setting DisplayPort-Mode to DP-1.1 causes the following limitations:
4K resolutions will be limited to 30 Hz refresh rate
Some DP-1.2 features such as multi-streaming (daisy-chaining) will not work.
Also, have you tested with the latest graphics driver for Intel® HD Graphics 530? Find the link below.
Is there a chance to test the behavior of your system while using another video output? (HDMI, VGA, DVI).
I look forward to your outcome with this.
No, the monitor does not have this ability. The monitor is a Dell P2715Q, which I bought a few weeks ago. I bought this monitor because I specifically wanted to use DP1.2 to take advantage of 4k resolution at 60 Hz. My previous monitor never had this problem connected from DVI at monitor to HDMI at computer. The computer is brand new (built 1/2/2016). I originally installed Intel graphics driver from the ASUS website and have updated to the latest drivers from Intel several times.
I am tired of constantly rearranging my desktop (due to resolution changes after the monitor wakes up-if it wakes up). Sometimes the monitor goes to sleep immediately after logging in after a restart. The desktop is never loaded and the monitor goes to sleep right after entering my password. I may have to hit the reset button on the computer several times to finally get to my desktop. I have tried every known solution and have uninstalled the monitor and Intel graphics drivers several times.
As of right now, I have rolled back to an earlier driver to see if that helps. If I can’t get things stabilized, I may have to buy a NVIDIA card as NVIDIA allows EDID information to be saved to file. So, instead of reading EDID from monitor, it will read from file making Windows 10 believe the monitor is attached. I believe this will solve the problems. I wish Intel would add that capability so I wouldn’t have to waste money on a graphics card that I really don’t need.
Let me sent this for review.
Please provide me with the information requested in the link below.
I will be providing you with the outcome for this.
Answers (N/A if not applicable)
Provide a detailed description of the issue
See prior posts and below
Does it fail every single time, or only sometimes?
If you can offer a % rate please do.
Desktop icons are rearranged 100% of the time when (if) my monitor wakes up.
Monitor fails to wake up (no signal from PC) at least 50% of the time.
Monitor goes into power saving mode immediately when I log into my windows profile (desktop is never visible) at least 25% of the time. It appears that the EDID information is never being received by the PC at login and the monitor stops receiving a signal and goes to sleep.

How to repro
Please provide steps to replicate the issue. These steps are very crucial to finding the root cause and fix.
A screenshot to illustrate the issue is a huge plus. A video of the failure is even better! Attach to the post or provide the YouTube link
Problem happens when I turn off monitor manually or when monitor goes into power saving mode (after 1 hour). PC is set to never go to sleep.
