Hello everyone!
Just found this great and helpful forum today and I would like to start with a little help request from you.
I don't know if I'm posting this into the right topic but because my problem is kinda the same as the topic starter post I decided to write here.
Okay so my problem is the following:
I have a brand new DELL Optiplex 3020 PC with nVidia GeForce 740 VGA, I have a BenQ and an ASUS monitor both have only VGA connections.
In my previous config I managed to connect the two monitors by connecting one to my external video card and connecting one to my integrated video card but since DELL is not supporting this I had to buy an external video card with multiple connections.
The card has a VGA, a DVI and a HDMI connection. The ASUS is my primary monitor so I connected it to the VGA port - works flawlessly.
I bought a VGA-DVI adapter to connect my other monitor (BenQ) into the DVI port and some strange thins happened.
First when I connected it the PC recognized it but the screen was completely black however my PC showed that I have 2 monitors connected. I can move the cursor and the icons to the extended desktop just I didn't see anything on the monitor, it said no signal.
Quickly I tried all the basic steps: restart computer, switch monitors...etc.
Results:
If I connect the BenQ to the VGA port - it works.
If I connect the ASUS with the DVI-VGA adapter - it's not working.
After restart - it doesn't matter which monitor I'm connecting with the adapter now it didn't work at all, my PC won't recognize it.
I tried searching for some kind of option in the nVidia control center but found nothing. Tried the forced detection there but nothing.
I'm using Windows 7 Professional 64 bit, Windows Updates installed, newest VGA drivers installed (currently 353.06).
Any suggestions?
Thank you!
