A:Answer 4/6/17
If your "older" tv uses HDMI 1.4, and not HDMI 2.0, I recommend you use the CERTIFIED HDMI 2.0 cables because the Sony 4K player will upscale to near 4K. Sony X800 states it will support 3D discs, but it requires the 18 GBPS HDMI 2.0. The 2.0 cables are backward compatible. The Dolby ATMOS sounds awesome! I love to use the Bluetooth headphones with it. Also, I read certain 4K HDR discs that play at 60 fps, rather than 24 fps, require the 2.0 cables. Better to be future proof.
