connect monitor to desktop

I moved my computer to another room to paint the room - my son reconnected everything with no problem. I moved everything back. I cannot get my flatpanel monitor to work. I have to use my old behemoth monitor, and there is no room for it. I want to reconnect my Acer al2016w monitor. It was previously connected using a blue cable and an adapter - I think that is called a DVI to VGA adapter, or vice versa. I put the connecting cable back in the same spot, the blue DVI plug receptor thing. The Acer monitor is powered and I can access the menu screen. I says I have an analog signal. I have tried telling it analog or digital, and also choosing DDC/CI on or off. I don't know if my choices are saved. Anyway, I never see anything on the monitor past the opening "windows" on a black screen. I get either a dark screen or a whited-out and "twitchy" screen. What do I do to get this monitor going again? I was not aware of changing any settings in the process of moving, but I have repeatedly been in the Acer monitor setup menu since I had no proper connection.

Double-check for bent pins on the plug and adapter

i see nothing obviously out of line. i do think i have a connection with my computer. Don't I? I get the windows screen. I think the problem is in some setting with the monitor. ??? Anyway, the pins look ok to my untrained eye.

If your video card has dual outputs switch it to the other port. Or try hooking both monitors up at the same time and find out which port is listed or shown as monitor 1. Your Bios screen and the windows splash screen will show on either port but when the desktop loads it will load on the primary monitor.
