I recently bought a 4k SHarp tv with built in Roku TV.
My goal is to cast 4k videos I find on my windows PC to my tv and be able to see them in 4k.
I have been able to use chrome on my PC to cast 4k youtube videos only. When you visit youtube on your chrome PC browser you get the cast icon at the top to show you an option to cast to TV "youtube" and then you select that and it opens the youtube app on the TV and it works perfect for 4k. I understand that basically this is a web address being sent to the app on the roku tv.
The problem I have is if I am on any other website other than youtube in which there is a video I want to cast or just the tab on my browser, then there is no option to cast to TV when you click on the cast icon. So, how do you cast or watch videos you find online on your computer to your TV so you can watch in 4k without having to buy a Chromecast Ultra?
I have tried the screen mirroring and it works, but I get lag and the 4k content does not look very sharp to me compared to casting to the youtube app on the tv in 4k.
Any way to do this with the Roku Tv installed in my tv already?
Any suggestions appreciated it!! thanks
