Dual display problem

[Sportsman]

my daughter is trying to set up two screens on a PC, she is running Windows 7 64-bit. Her video card has two outputs, VGA and DVI.

she has two ViewSonic monitors both with VGA input so she has an adapter on the DVI output on the card.

I have exactly the same setup and it works fine.

For some reason when she tries to set up the two screens it recognises one correctly as a wide screen with the appropriate resolution but the other it recognises as a 4:3 screen and we can't change the resolution to the correct one.

Does anyone know the potential cause or a work around that would get it to work correctly

thanks

Have you tried swapping the screens over, or swapping yours for hers

Never liked the limitations in windows handling dual screens. I use software called Ultramon that will sort that problem and also gives a task bar to the second screen

I have just spoken to her again.

The problem seems to be with the screen attached to the DVI output via the adapter. If she swaps the screen over the problem is on that side.

We have changed the adapter so it isn't that (probably)

The screen only have VGA input and the reolution is fine on both screens when connected to VGA output.

I know you can get a VGA splitter lead to allow running both screens from the same VGA output socket.

Is that likely to work?

Thanks

No that will just give you two screens that look the same. What version windows ?

 

Try right click desktop go to properties and then display (where u normally change resolution)

 

there you might see 2 screens on the dialog click one then adjust resolution or select from the drop down the second display and change resolution

Argh cant edit post on phone just seen its windows 7 right click on desktop then go to change resolution. If u dont see that clixk personalize u can find resolution throug there.

Hi Andy

We can't reset the res through change resolution and I can't find a way to do it through personalise

[Andy_1984]

You cant change it by using the drop down?, weird.

 

try out ultramon demo you will be able to do it with this software. if you like you can buy it, or whatever.
