Here are some possible options:
- Some Samsung TV's support WIDI (Intel Wireless Display) that may work.
- Miracast is another wireless display standard and some Samsung TV's also support this. It is supported in Windows 8.1
- You could also set up your PC as a DLNA server which the TV would be able to pick up though that is only for media. There are plenty of PC options for this but the built-in media player does it natively.
