A:Answer If you don't have an HDMI cable, then yes, you'll need one. That being said, you don't need the high end ones. You can find an HDMI cable on Amazon for cheap. Most cable boxes and DVD/Blu-Ray players use HDMI, so if you plan on connecting them to the TV, you'll need extra HDMI cables (you can reuse the ones you have if you already have them).
