Windows 7 cast screen or website to Roku or Xbox one

[tsomek]

Hi,

I have Windows 7 Ultimate on my main computer and want to cast my screen or just a website to my Roku 3, or to my Xbox one.

The goal is to be able to watch video live-streams (usually Flash) that are available online, on the big screen.

As an alternative I could also stream from a Windows 10 machine, but with an older CPU that unfortunately doesn't natively support Miracast.

Is there a way of achieving this?

Many thanks!

you could just plug your computer into your TV.

OK - maybe it's my mistake for not having added that this needs to happen wirelessly - without connecting the computer to the TV.
But this is why I was specifically asking about casting "to Roku or Xbox one" in the first place...

Any other ideas?

Been looking for a similar solution (Windows 10 & XBox One) and not been able to find anything.
