Hi shanksri88

Do you see this border all the time (desktop / full web page) ? and is it an overlay or can you see (in the case of a web page) all the web page inside the border ?

yes i see it all time and everything is displayed inside the border its jst like a movie with black borders around it................

I'm thinking this may well be a monitor problem can you go to its manufacturers web site and download your monitors driver (new driver) then re-install your monitor driver.

Essentially your monitor/graphics card is not scaling the lower resolution to occupy the full screen. Are you able to scale the image in the monitor setup options?

Are there any scaling options at all in the NVIDIA control panel? It should look something similar to this:




edit: On my drivers, this setting is listed under "Adjust Desktop Size and Position" on the left hand menu.

my monitor setup doesnt help nor there is an option in my NVIDIA control panel for flat panel scaling............
