If I'm not mistaken the Toshiba 1110 Series comes with ATI Video Card. The Drivers for the ATI have Color settings which includes GAMMA.
So try this.
- Right Click on your Desktop.
- Choose Properties
- Select the Tab "Settings" which is the right most tab.
- Once on that tab on the Bottom Click on the Advanced button
- Find the Color Tab as illistrated in the pic I'm going to attach.
You can try resetting everything to Default as well and see how it goes.
