U2414H, wake problem, full reset of system required
Currently running a self built rig with the following information:
Processor - i7
Video Card - Sapphire R9 290X
Monitor 1 - Dell U2414H purchased January 2016 from New Egg
Rev A03
Using the following to connect - DP out to DP in (also Tried DP out to mDP in) same thing happened
- also have a USB cord connector plugged into tower to connect USB ports i monitor
Monitor 2 - Dell SP2208WFP connected by HDMI
Video Card Drivers updated to latest Radeon Crimson ReLive 17.3.1
Resolution - 1920x1080
High Performance Power Plan
This problem has been happening for a few weeks, and it came out of nowhere. Essentially, I put my computer to sleep every night and it self-wakes in the morning. I move my mouse or hit a key and the monitor usually comes back to life and I go on with my business.
Recently, the monitor will not wake from sleep. I have tried cutting all power, doing a hard 30 second reset, restoring to factory settings, and even changed connections from mDP to DP.
Nothing has worked. I have to fully restart my system for the monitor to wake from sleep. I have found that cutting power from the U2414H also enters sleep mode and will not wake - regardless if the power is cut from the power button or by taking the power cord out. Same thing, the entire computer will have to be reset.
This is incredibly frustrating. I can't just restart my system all the time just to wake the monitor. Its just over a year old! My other dell has been amazing! What gives with this otherwise beautiful monitor?

What is the 20 digit serial number on the U2414H?
* Turn the monitor off
* Disconnect all cables (power, USB, DP, mDP, HDMI, DVI, VGA) from the rear and side of the monitor
* If a mechanical monitor power button, press the button in for 30 seconds (clears any residual power in the circuits). If not a mechanical power button, just wait for 30 seconds
* Reconnect all cabling and retest

Also, this did not correct the problem. I had to restart the machine again. This time, it did not wake upon restart but did when i disconnected the DP from my PC and reconnected it again.
This is really frustrating.

Built on August 23, 2015. Because you purchased it from a reseller and not Dell, we can only warranty it through August 23, 2018. But, the fact that it worked well over a year, to me, points to something else, not the monitor. Prior to the issue, did you change the video card driver? Did you do a computer BIOS update? For testing, I would also disconnect any USB devices from the monitor and connect them directly to the computer. So the only cabling connecting the monitor to the computer would be DP to DP cable.
