Dual Display Question

[AkhilStyle]

Hi,

I would like some help regarding mirroring a display on 2 monitors.

I have a new 24 inch monitor that can display high resolution - which is what I need.
I have an old 15 inch monitor built in to a cabinet (so hard to replace).

I want to mirror the image on both screens.

At present both monitors are plugged into the VGA port of the graphics card (with a splitter). When I lower the resolution in the windows settings the picture displays fine on both screens. When I increase to 1680 x 1050 the new screen displays it fine but the old one says max resolution reached and does not show the image properly.

Is it possible for the card to output display different resolutions for each screen (a lower one for the old screen) so that the images are still mirrored and I can display higher resolution on my new screen? My current graphics card is old and only has 1 VGA output - I'm guessing I can get one with 2 VGA outputs - but this automatically mean I can set each output to a different resolution?

Thank!

Yes, if you get a card with two individual connectors you can have two screens at two different resolutions.

Edit, no just tried and both my screens are the same resolution even though they are 1080P and 3560X1440P natively, extended desktop which I normally run works fine.

Don't think so. You can have the displays duplicated, or you can have them at different resolutions - by definition you can't have both. You can set it to show two different outputs at different resolutions but they'll operate as two different screens rather than duplicated. The only way to do what you're after is by outputting a duplicated screen at a higher resolution if the smaller monitor can then downscale it to an output it can show, which you've tried and doesn't work on your setup.

Short version - you can have duplicated or different resolutions, but not both.
