I have a MacBook Pro 15" about 5 years old. I have a 5 meter cord that takes the external video output from the Mac and connects to my 32" TV via HDMI. I use a separate audio feed since it does not provide that on the Mac output. I was just watching "BlackList" on Netflix here in my Bedroom office.
Newer Macs (and I suppose other Windoze types) provide direct HDMI, YMMV!
DVI to HDMI
That and when I first moved to my apartment five years ago, my old tube TV went on the fritz the color tube went out and everything was either purple or green, but otherwise it worked just fine. But being the cheapskate I am, and considering that most of what I watch on TV is news, I just turned off the color setting on my TV to B&W and watched TV in B&W for about 2 ½ years until I finally broke down and bought a new flat screen HD TV.
Or get an Apple TV and just stream wirelessly from your laptop or ipad with Airplay.
