First I'll apologize because I have a very limited understanding of all these things. After spending too many hours trying to figure out why windows 8.1 wouldn't let me connect to the dongle I got to pair my tv to my laptop, I think I figured out that my laptop's wifi card isn't on the list of miracast supported wifi cards. My question is this: does that mean I can't cast to my tv? Are there alternatives to miracast, chromecast, etc. for Windows 8.1 ? The more I look for info, the more confused I get.
