RE: Latitude E7470 External Monitors with Dock Problems
I am having the exact same problem with my Dell Latitude E7470. In fact all three that i bought are displaying the same flashing monitor issues. I installed the Synaptic Firmware at the urging of a Dell representative and my external monitors quit working entirely. They were kind enough to send me a replacement laptop. Since then the problem continues, I have updated to the latest Bios 1.4, and installed the updated display drivers. Both updates release in March 2016. I refuse to update the Synaptic firmware again.
As I am typing this, my screens just went black. UGG. I have had dell open an escalated ticket. Hoping to hear back from them on Monday or Tuesday. This is a rampant issue that needs to be addressed. If it's not resolved for us soon, I'll b requesting a refund and buying from another vendor.
My laptop has the Intel Core i7 processor. My docking station is a Dell Eport PR03X. I am using one VGA and one DVI for external monitors. (Flashed again!)
