I've been trying to find info and maybe a solution to my smart TV's poor streaming performance - the vizio tv has a speed test utility and it shows less than a 5Mb connection on a 100 Mb service - a pc attached to the same router gives a speed of 100 Mb from 2 different sources - it's not an ethernet cable problem - and the tv's wifi gives the same results. Netflix seems to be able to adapt to this but Amazon streaming starts out really crummy for about a couple of minutes and then becomes watchable. I'd get a Roku but there's no available HDMI ports since the only 2 are in use. I guess I can go get a stereo amplifier that can switch HDMI to compensate for lack of HDMI ports - a new TV would probably cost more than a new amplifier. My current amplifier doesn't have HDMI at all.
