Solved Second display not working at all.

[djjamieg]

I have two identical AOC monitors. I first used a Palit Nvidia GT640 graphics card and also a Radeon HD6450 to no avail.

I've tried the second monitor with the following DVi, DVI-D and HDMI to VGA cables/adapters and nothing.

That's using both the windows right screen resolution option or the propriety Nvidia/AMD to configure the multiple display options.

If someone can help me finally crack it that would be great.

If both monitors are using VGA then this is what is happening,

Short of monitors that have more than just VGA or getting a DVI-VGA converter (nothing like the adapters you have been using, and cost a fair bit more), there isn't much you can do.

But I have done in the past which is what is odd. With other custom built machines with these exact monitors it was working. Wasn't straight forward though. If I remember rightly in the past I had to make the second monitor the main one cable wise then extend, then physically switch the monitors on the desk. Weird. Thanks
