In display settings, multiple monitors are identified in one monitor

[Charteris]

Hi

I have a Sony VAIO VPCSB3S9E/B Windows 7 64 bit. It has a 1366 x 768 display. It also has the stamina/speed button switch which I had almost permanently on Stamina. Today, however, I switched to Speed and the resolution is odd. It's stuck at 1078x768. On the resolution screen, there are two monitors 'sharing' one screen. Check it (sorry, it's in Czech):



When I press Identify, I get the two numbers sharing the one screen with a border between the two.



I tried to alter a few settings here but to no avail - could someone throw me a bone?

Thanks

David

Hi

Ok, so it seems your Laptop is detecting another display. First of all can you please verify that you do not have an additional monitor/tv connected? If not then check the display ports on the laptop (VGA, DVI, HDMI etc) for any dust of something that shouldn't be there.
If this seems all fine then select the option that currently says something like "Duplicate These Displays" and select "Show Desktop Only On 1" and see how that goes.

Post back with the information
