suggestions/info - I want a computer/HDTV monitor combo

I have a 1366x768 42" on a PC for TV and gaming, but the resolution is too low to be my main monitor. Instead of using a TV as a monitor I'd look at some of the monitors that include TV options.

The Westinghouse L2410NM is probably the most popular choice for your intended use. It's a 1920x1200 MVA panel with VGA, HDMI-HDCP, component, composite, s-video, and audio inputs (not great speakers). There are a few other models with similar features.
