RE: DELL S2415H blinking!
Open the S2415H User's Manual to page 44. Run the stand alone Self-Test and Built-in Diagnostics.
* If the blinking happens during the test, get it exchanged
* If the blinking does NOT happen during the test, the monitor is not at fault. The fault lies with either the cabling, computer, video card, or video card port
