I have and HDMI port on my TV, but oddly, it is not an HD Television. Can I use Roku even though my TV is not HD? The Television is a Philips model 32PFL3506/F7 and the HDMI port says HDMI 2. We do not have a Roku, but were thinking of getting one. But we heard that they only work with HD TVs and ours is not HD.
