I have a VAIO laptop running Windows 7 with two monitors connected. One monitor is connected through the VGA port, the other is connected to the HDMI port. Both monitors are identical, and the one that is connected to the HDMI port is connected using an HDMI/VGA adaptor. I've been trying to set up my monitors for extended display, however, I'm only able to extend the display with one monitor at a time to the laptop screen (my goal is to extend the display across the two monitors only). When I go into Control Panel to manage the display options, and I click on "Connect to a projector", clicking on "Disconnect Projector" displays my laptop screen on the left monitor, and clicking on "Projector Only" displays my laptop screen on the right monitor. When I click on Extend, nothing happens -- whichever screen is currently displaying is the only one that displays while the other remains off. When I click on the monitors that are displayed in the Screen Resolution window, and then click on "Extend these displays", I get an error message that says "Unable to save display settings." It will only let me save my settings if I select "Show desktop only on 1" or "Show desktop only on 2". It will not save my settings if I select "Extend these displays" or "Duplicate these displays". I've been at this all morning to no avail. Both monitors work as well as both the HDMI and VGA ports, but I can't seem to get both monitors and both ports to work at the same time. Can someone please help me figure out how to display across two monitors at the same time?
