Now, 4K resolutions comes with the latest in HDMI technology. HDMI 2.0 is the next generation of one of the most commonly used formats in home audio/video systems. This upgrade is designed to increase both frame rates and color for your 4K viewing. There's been a lot of confusion as to if you will need to switch out the old HDMI cables with new ones. After some research, it seems like the most recent version (HMDI 1.4) only needs an upgrade with its internal microchip on your devices and sources, not the cable. I think the sky is the limit with the newest technology coming out. It's crazy to know that TV technology has come so far from the original 16 frames per second rate.
