Hi. I got a Toshiba laptop. Somehow-and i really dont know how- i connected it to my tv via VGA. My laptop screen was all black and i was able to control everything through my tv. But i raised the screen resolution more than the 1024x768 and my tv screen went black. when i remove my vga cable i control my laptop normally but when i connect it to my tv both screen are on and i have limited control through my tv.
