Ok, we were wondering about that. Did you hook up directly with a cable?
A lot of laptops have an HDMI out.
There’s also a box like this that would work with HDMI.

We got a cord that hooks up from the HDMI port on the laptop to the HDMI port on the TV. We also got an adapter to go from the headphone port on the laptop to the stereo. Instructions for hooking it up abound on YouTube and other websites.
