Are you wired or wireless on your client connectivity? Until I upgraded my wireless access points that now support 6E (my Shield TV connects at WiFi 5 speeds…I guess until an update brings it up to 6–no 6GHz radio so I don’t expect 6E), WiFi was not good. I ended up getting a NVDIA Shield ProTV because my living room TV only had a 10/100MB wired network and the Shield has a 10/100/1000MB. I found that my highest resolution file was Gemini Man (which is what I use now to test clients) was pulling a 145MB/s stream at 4K HDR. Don’t get me wrong, it looks awesome but that seems to be the upper number as far as streaming speeds for what I have as far as my 4K content so whatever I use to connect has to perform at a minimum of that speed. My older WiFi could not do it and neither did any of my TVs with 10/100MB network cards on them…come on, TV manufacturers, step it up.
