laptop to tv

i cant get my aspire one to show up on my tv using vga to hdmi

Hello,

Press the FN key and your computer's corresponding "F-number" key. For instance, on some Toshiba laptops you press the FN+F5 simultaneously four times to get the TV-Out setting. The "FN" key is a short-cut key on most laptop keyboards. Note, the combination keys that you may have to press depend on your laptop. Here's a brief list: Acer Fn+F3; Dell Fn+F8; Fujitsu Fn+F5; Gateway Fn+F3; HP Fn+F5; IBM Fn+F1 or +F3, +F7 +F8; NEC Fn+F3; Panasonic Fn+F2; Samsung Fn+F4 or F5 or F6; Sharp Fn+F5; Sony Fn+F7; and Toshiba Fn+F5 or +F7.
