A:Answer Mike, Are you looking to bypass your Roku Ultra 4K Streaming Media Player and plug your Ethernet directly into the TV so you can use its streaming interface? I don't know if the Ethernet port is Gigabit. For me, it didn't matter. I installed the 49" XBR 800H with a Roku Ultra 4K Streaming Media Player via WIFI to the Roku. In my opinion, the Roku Ultra 4K is a better interface into streaming content with more flexibility. The 49" 800H was installed at my in-laws. In my home I installed the 49" XBR X950H with a Roku Ultra 4K device. The Roku is plugged into my network with an Ethernet cable. The response time through the Roku Ultra is really fast compared to the older Roku device it replaced. Sorry I am not able to answer your question directly.
