Having issues connecting 2 monitors to Acer Aspire 5740 laptop. This is a 64-bit laptop running Win 7 Professional. Per your suggestion from earlier question submitted, I ordered two pieces of equipment from you: the UD-160-A docking station and the UGA-2K-A (via Amazon). I have 2 identical Dell 1704 FPV monitors. They are capable of being connected via a DVI or a VGA cable. I prefer to have both be DVI. When I connect a monitor to the DVI port on the UD-160-A - that monitor has terrible flicker and horizontal color lines and scrolling. I have tried using a VGA adapter and connecting the same monitor via a VGA cable to the DVI port - with same results. So using VGA or DVI to the DVI port on the UD-160-A - the monitor has flicker and nothing can be viewed on that screen. I have the UGA-2K-A hooked up to one of the USB ports on the docking station. Have the 2nd monitor connected to it via DVI (or VGA) and either works fine. Have tried switching monitors to rule out a monitor problem - the issue follows whichever monitor is connected to to the docking station DVI port (whether straight DVI or with a VGA adapter). Extend is set in display properties and resolution on both external monitors is identical as1280x1024. Once both external monitors are connected (and working) the intention is to close the laptop lid and not use its display when it is connected to the dock. Also tried moving the monitor that is connected to the UGA-2K-A to a USB port directly on the laptop as opposed to the docking station, thinking maybe two monitors on the docking station was too much. That monitor worked fine - however, the monitor remaining on the DVI port on the UD-160-A still flickers and is not usable.
My only conclusion is a defective DVI port on the UD-160-A? My Amazon order was 104-4745234-8629837 (7/31/10). Just now got around to hooking these up on my daughter’s new laptop.
