Wisair Wireless USB Audio/Video Adapter is an interesting little gadget designed with laptops in mind - to stream any laptop content to any HD screen. Thus, you can wirelessly stream movies, TV, photo slideshows, presentations, web content, and more. It'll work with desktops as well, but really their target market is laptops.
 
The Wisair Wireless USB Audio/Video Adapter Set is a USB adapter that sports a HDMI video/audio support and VGA connectivity with stereo audio support through a 3.5 mm audio jack, and offers 32-bit True Color depth and up to 1400x1050 screen resolution. It also features 48 kHz, 16-bit stereo sound and HD video resolution up to 720p.
 
The wireless laptop adapter plugs into any USB port on the computer. A USB device adapter plugs into the A/V base, which is connected to the TV via HDMI port in any TV or a VGA port in any projector and monitor. Audio can be delivered via the HDMI port or a 3.5mm stereo port. It avoids the Wi-Fi wireless spectrum by using 3.1GHz to 4.7GHz range to avoid interference and works up to 30 feet. It does require some line-of-sight, so don't expect this to work in an adjoining room with lead-lined walls. It also does some compression, so there might be slight video quality degradation.

It is a bit pricey at $146, but can you put a price on cleaning up the wire clutter? You can read some of the user reviews here and decide if this product is for you.
