Short range wireless audio/video is still going to have a lot of the same issues in terms of quality and latency. Some solutions will do lossless video over short distances (the 60GHz wireless video stuff for example), although I'm not sure about latency.
What are you actually looking to put on the TV, though? If it's just media playback, there are lots of solutions involving either dedicated media players or HTPCs that are going to provide a much smoother user experience than how you describe using the laptop (they'll play stuff over your wireless network). If it's videogames, then there are solutions for that too, various in-home streaming options such as those provided by nVidia or Valve that can stream from your desktop computer upstairs to a cheap dedicated device (like an nVidia Shield or a Valve Steam Link, which will be out in November for $50). Those are not lossless, but the quality is decent, and since they're gaming focused, the latency is pretty low. They're designed to use a gamepad with them, though.
So maybe something that is more specific to your use case might work better. Some of them (like the nVidia Shield) could be used for both media and gaming. I think SteamLink is gaming specific, it's pretty optimized for that one task and nothing else, hence the low cost.
