The rise and fall of 3D TVs came and went relatively quickly. Despite a brief period of whirlwind success in the early-to-mid-2010s, the concept of 3D televisions has mostly been relegated to a mildly interesting novelty rather than the wave of the viewing future it was poised to be. That said, while they’re not the dominating television format these days, there are still some 3D TVs floating around, either as holdovers from that high time or the occasional new creation. If you’re interested in one, you could probably get it for dirt cheap.

Before you buy a 3D TV, though, there’s something important you should know. First of all, there are actually two kinds of 3D TVs: Active 3D and Passive 3D. While both of these configurations provide the same general effect of adding pop-out depth to what you’re watching, they achieve it in completely different ways. The kind of 3D effect a 3D TV uses can affect both your level of comfort while watching and the necessity of certain peripherals, so it’s important you know the specifics of both types.
