A direct cable/wired connection from your HDMI out on your laptop to HDMI in on your TV would be the cheapest and easiest.
WiDi will work, if your laptop has it and you have a smart TV.
Intel Wireless Display technology, or WiDi, has become increasingly common among both laptops and HDTVs, and you might already have everything you need to wirelessly stream your display. Many connected HDTVs support WiDi and Miracast (wireless smartphone and tablet streaming that uses the same technology), and if yours doesn’t you can get a WiDi/Miracast adapter for around $50. You need a computer with WiDi built-in, and most current Intel-based Windows notebooks should already have that covered. This system works very well for playing movies and browsing the Web on your HDTV, but slight latency keeps it from being ideal for fast-action games.

Thanks, I think running an HDMI cable will work best for me.
