So I recently got an external display, the 24" Dell S2440L. I have it hooked up to my laptop via an HDMI cable. (So there is a MIni Displayport to HDMI) adapter. I run my MBP in clamshell mode (I have a bluetooth keyboard and mouse) and it all works perfectly. Except the occasional flash on the monitor.


It doesn't happen too frequently, but enough that I notice it. The reviews online for the display are excellent, and I absolutely love it. The flashing is just a brief "blink" I suppose in the display. No other issue besides this. I was curious to know if anyone else has this issue with their display. I assume it's got something to do with the cable or computer port, not the actual display. Any thoughts?


Thanks in advance, and I apologize if this is in the wrong subforum.
