I recently was given two VGA only monitors: Dell e173FPb and a model number not on me. So I purchased these VGA converters: HDMI to VGA Converter and USB 3 to VGA Adapter. My hope was that I could use both monitors at the same time for 3 displays. And it worked.
But more recently, I decided to bring one monitor home, leaving the other at work. I have tested both monitors and they work well with the HDMI to VGA converter.
So I decided to use the USB to VGA adapter at home as an extended display. Unfortunately it seems to not work with either monitor. With the Dell monitor, I get brief video only when switching the monitor on and off or switching settings. With the other monitor, it only seems to receive video if I duplicate displays, which is useless to me.
Also, I doubt this helps, but I have successfully used the USB to VGA adapter with a different monitor entirely, so I know it can work with that setup.
This leads to a few questions that might help me solve this issue, or at the very least, prevent my frustration from boiling over.
- Why am I able to use the USB to VGA adapter in a 2 monitor setup but not in a 1 monitor setup?
- Why does the Dell monitor only receive video briefly when switching?
- Why does the other monitor only receive video when duplicating displays?
- Is there any way at all I can fix this to work with my current monitors (and not buying a new one)?
