1.What video outputs has your GPU?
2.Try another HQ VGA-VGA cable
3.Try another HDMI to VGA HQ adapter
4.Try DP to VGA HQ adapter or DVI to VGA adapter if your GPU has DVI port
5.Try to reduce resolution or refresh rate for second monitor
the Projector and the monitor are both VGA only.
I tried switching the main display to the HDMI adapter and got no signal - took the adapter off and plugged straight in to VGA port on the card and now get no signal on the display (this connection worked fine before trying to use HDMI adapter).
Cannot find a VGA to DVI-D adapter ( this card is DVI-D ) - all adapters I can find are VGA to DVI-I.
No way to reduce resolution on 2nd monitor since mouse will not responde when both are plugged in!
DVI-D has not analog signal. There are no DVI-D to VGA adapters. It is looks like you need another HDMI to VGA adapter(HQ).
1.Try to leave only second display and reduce resolution for this display. Then plug your first display.
