Hello
I also have a Dell U2415 monitor running from an Gigabyte computer via Dells mDP to DP cable. Running on a AMD Radeon R9 270OC gfx card. Native resolution. And latest drives.
Have same issue "Periodically and increasingly commonly, it starts flickering and flushing black repeatedly for anywhere from 1 second to 30 seconds. The OSD, if open, shuts down with each flicker. "
I'm tried shutting the monitor down as well as running it with only the power and DP cables attached but this does not resolve the flickering.
Disconnecting the DP cable stops the flickering and the "No Input" OSD notice appears on the screen continuously.
Changing the resolution, refresh rate etc, does not appear to help.
Thanks.
