Element TV’s are usually lower price points and therefor lacking in features. Looking at the spec for your model it does not appear to have casting hardware built into like a Samsung frequently does. Try buying a Google Chromecast device.
Appreciate the feedback. The tv is in my 10 year olds room, hence the cheaper tv. Was hoping to avoid another fire stick or other device, but sounds like that would be the simplest solution other buying a better tv.
For many years I was a confirmed Roku users. I also have a couple of AppleTV boxes. But about a year ago, I retired everything and switched to just Amazon FireTV sticks and Cubes. They're not perfect but I think they are as good or better than just about anything else. If/when there are problems it stops a lot of finger pointing. It can't be the other guy's problem when there is no other guy.
