RE: Latitude E6440 display blink when connect to external monitor via hdmi to VGA converter

Hey All,

I've noted something that seems to work pretty well.

  • The HDMI output blinks when the laptop is fully charged, with the AC power plugged in.
  • Unplug the AC adapter, and the display stops blinking.
  • When the battery is drained, & AC is plugged in, the screen does not blink.
  • When the battery is fully charged, the display begins to blink again....

I've been able to use this as an interim solution, (unplugging the power from the back of the machine, and plugging it back in back in a few times during the day)... until Dell figures it out.
