SE2717H, "Flashing" black screen
So I got new monitor and for some reason sometimes when I start my pc monitor is "flashing" black screen - aka every couple seconds screen go black for milisecond, like it is turned off and on again very fast.
I dont know what is problem. This is second SE2717H monitor I have - first one i had for 1 week but I returned because there was 7 dead pixels and I didnt have same kind of problem with that one - now that I have new one I get this problem at least every other day. I installed drivers for monitor and Dell monitor app. Like is said the most weird thing is that it happens just sometimes, and I have filing that it have to do something with power supply since it start to have problems especially when screen go black because im not on PC, and when I try to "wake it up" this problem start - but that is just guess because sometimes it start from the moment I turn on PC.
What is problem? I really dont want to change monitors again.
Spec:
Windows 10 Pro
CPU: Intel i5 6600 3.3 GHz
MBO: ASUS H110M-C, DDR4
RAM: Crucial 8GB DDR4, 2133 MHz
GPU: XFX AMD Radeon RX 480 RS Hard Swap, 8GB GDDR5

* Does this flashing happen when running the SE2717H standalone Built-in diagnostics (page 40) ?
* Are you connecting to the PC like this?
PC Radeon RX 480 HDMI out port --> SE2717H HDMI to HDMI cable --> SE2717H HDMI in port
* Press the SE2717H Menu button
- Go to Others
- Choose Factory Reset
- Does the bottom of that menu show Resolution: 1920x1080, 60Hz ?
- Exit the Menu
* Have you tested this SE2717H and its HDMI to HDMI cable on a different PC to see if it also has the flashing issue?

No. Flashing when my monitor is started "normally". I will try that also when (if) my monitor is started with "flashing" again.
* Are you connecting to the PC like this?
PC Radeon RX 480 HDMI out port --> SE2717H HDMI to HDMI cable --> SE2717H HDMI in port
Yes, I'm connected with HDMI cable like that.
* Press the SE2717H Menu button
- Go to Others
- Choose Factory Reset
- Does the bottom of that menu show Resolution: 1920x1080, 60Hz ?
- Exit the Menu
I did it. May I ask, why does it say in bottom right corner "Maximum 1920x1080, 60Hz", when my monitor should be 75Hz, and I have 75Hz option in windows settings?
* Have you tested this SE2717H and its HDMI to HDMI cable on a different PC to see if it also has the flashing issue?
Yes, like I said, I have even tested same HDMI cable on this same monitor (my old one with dead pixels that was returned). Also tested on laptop-TV and other PC, so I don't think cable is issue.

If Windows and the AMD Radeon RX 480 control panel both show the AMD FreeSync 75Hz, you should be setup correctly. I am not sure if the monitor menu will reflect that 75Hz. The User's Guide only shows 60Hz. I also do not see anything in the monitor menu to enable or disable AMD FreeSync, so it must all be done within the AMD Radeon RX 480 control panel. Another SE2717H owner will need to post their menu result.

That is odd. Is the monitor power cable plugged into a standard surge protector, then the wall outlet?

The fact that you have to power off/power on the PC means that the PC video card (Radeon RX 480) had stopped sending a signal to the SE2717H. The PC power off/power on forces the PC video card to initialize the signal to the SE2717H. Is there another PC there to test the SE2717H on to see if the issue follows the monitor?

Not at the moment, since my other PC have no HDMI output and only have old VGA.
But like I said, this same monitor (SE2717H) worked fine on this same PC for 7 days before I returned it (dead pixels, factory failure) and old monitor I used for years never had this problem. Same monitor is now on other PC - still working normally. Everything was connected in the same way.

Still not sure if the 2nd monitor is at fault, but, you could initiate another monitor exchange. When the 3rd one gets there, test it. If the 3rd has the same issue as the 2nd, the 2nd was not faulty. Send the 3rd one back. If the 3rd one works, send the 2nd one back.
