Hi DavT. Which Ethernet cable to use to use for the LG 65 inch Class 4K Smart UHD TV (64.5'' Diag), Model # 65UM6900PUA is at your discretion. Everyone has different needs for their network setup. Start with the speed of your home internet connection. If you have gigabit internet (1Gbps), an old Ethernet cable will hold you back. If you have a slower connection — perhaps 10 or 20 megabits per second — you’re good with anything Cat 5 or newer. If you don’t know your internet subscription’s actual speed, connect your PC directly to the modem and load a speed test. Doing so will give you a starting idea of what you’ll need in terms of wired connectivity. If your subscription only supports 50Mbps downloads, purchasing a 1Gbps Ethernet cable is simply overkill — at least for now. Finally, consider your router. Many cheap routers only support Ethernet up to 100 megabits per second, so the router will bottleneck anything newer than Cat 5. Even the best home routers rarely support more than gigabit Ethernet, meaning Cat 6a and Cat 7 are of questionable use. If your ISP provides a slow, clunky modem/router combo, request an upgrade or purchase a standalone router with better connectivity. In most cases, cat6 or cat6a Ethernet is good enough to provide better transfer speeds. However, you can go for the most advanced cat7 cables too...^IFV
