Have checked the forum and although there are some similar problems, I’ve can’t see this particular one. The issue may be down to user error, but here goes.
Running a Surface Pro that’s about 2 years old, Intel i5 7300U 2.6GHz 8GB RAM. Plugable drivers are up to date.
I bought the docking station to move to a 3 display set up and I’ve got it connected to 2 Samsung 22" monitors (one new, one about 3 years old).
I’ve tested the connections on both monitors. With either monitor, I can run a 3 screen display, with one monitor connected from the docking station HDMI port and the other from the DVI port, using the DVI-VGA connector.
Using an Amazon Basics DVI-HDMI cable with either monitor results in the monitor no longer being seen by Windows (Detect in Display Settings doesn’t find the monitor on the DVI-HDMI connection) and I go back to a 2 display set up (Surface screen plus the monitor connected to the docking station’s HDMI port).
Both the monitors are set at 1920 x 1080 resolution.
I’m not sure if this is a problem with the DVI-HDMI cable or screen settings or even if I’ve just mis-understood specs, and the docking station DVI doesn’t support DVI-HDMI cables.
