So if you're considering getting a new TV, a 4K Blu-ray player, or a 4K HDR media streamer, you may also be in the market for new HDMI cables. Fortunately, you can get the maximum performance possible in an HDMI cable for less than $10. That is, if you even need new cables…

I get into recommendations on new cables below, but first a bit of advice.
