For a long time I was using the UD3900 docking station with my MacBook Air (2014) to have a 2nd external monitor. Monitor #1 went from my thunderbolt directly to my one TV monitor. Monitor #2 went from my USB 3.0 to the Docking station, from the DVI to the 2nd TV monitor(HDMI). The set up, while a little cumbersome with wires, worked very well. Now, the 2nd monitor is not receiving the signal from the docking station. I have tried using the HDMI output from the docking station with no success. My Mac iOS updated and current and just updated the docking station’s firmware and still no success. I realize my MacBook is older but it still works great. I would prefer to not buy a new one and just update it’s SSD memory when I have to. So…
Can the docking station be “fixed” so I can get back to having a second monitor?
Do I have to buy a new docking station?
Am I SOL and need to get a new MacBook with a Thunberbolt 3 and appropriate docking station?
