If not, then research WIDI. As to the mouse and keyboard controls, there are remote units but one problem at a time. If there is any issue with LAG such as game play or you can't stand the mouse lagging by almost a full second then your quest is over for now.
Hi, I want to be able to control my computer with a mouse and keyboard from my basement and have it show up on my tv.
I've seen http://www.warpia.com/ but this is line of sight only. You can't go though the floor or walls.
This is what I want http://www.icron.com/products/usb_new/usbvideo.php#PCTV (check the video)
But they seem to only be in development and are not being sold. I don't know when this is even from.
Please keep in mind that I want to do this from my desktop not a laptop to be brought to the basement. And I don't want to have to run cables though the floor
