3 display set up , different screen sizes, 1 VGA and 1 HDMI

Am having trouble with a 3 display set up:
1. Laptop display OK
2. HDMI flat screen OK
3. VGA smaller flat screen

Windows 7 will not allow me to duplicate desktops 1 and 3 ( or any other combination) that allows 3 different views.

Suggestions ? Thanks

It isn't Windows that is stopping you but the laptop itself. The laptop may have two additional display ports/hookups in addition to the laptop's own screen but it doesn't mean you can use all three at once. You don't say what laptop, but you will likely find that the video card in it can only support up to two display devices at a time, with one of them being the laptop's own screen.

You want to run three displays off of a laptop, you're going to need an external video device something like this, - StarTech USB 3.0 to VGA External Video Card Multi Monitor Adapter – 2048x1152 USB32VGAE USB 3.0 to VGA Interface

Set screen & projector resolutions to different sizes?
I am using RC1 on an HP Mini 2140 PC with 1024x576 resolution. I just can't work out how to set the projector and screen resolutions to different values. Projector resolution is 1024x768. If I use the "duplicate screen" setting, it insists on using the 1024x576 for the projector as well. The only...
