i used a PANASONIC HD TV and it worked. (connected via HDMI)
First of all it didn't detect my laptop keyboard so i used an USB one.
After that i played a little, and i looked at the Hardware Specs. I attached the pictures (i don't know if helps). The main difference is that i have ATI 2600 HD wihtout XT, i have the basic version but also 256Mb dedicated (if matters)

Now that i'm in it, what should i do (download/delete....etc ) to make my laptop monitor and keyboard work cause i don't have the TV amd the usb keboard with me all time.
