It appears you have VGA on both so what stopped you from using that? Sound can be from some other speaker set or over a second cable to the TV.
I don't see why you would need more than a pair of cables here.
My x54L doesn't have a HDMI port only a 1 x VGA port/Mini D-sub 15-pin for external monitor. But, the TV-LG - 42" Class (42" Diag.) - LCD - 1080p - 120Hz - HDTV does. What do I need to convert the signal to watch dvds? The TV specs: HDMI carries both digital video and audio (at resolutions up to 1080p) in a single cable. It provides the highest-quality connection between your TV and Blu-ray players, personal computers, video game consoles and more. The more inputs your TV has, the more devices you can connect directly.
