Wireless Monitor

Intel's solution is cool, but it has some drawbacks ... one being that it's 720p max, the other is that it has that lossy compression to lower the necessary bandwidth (=> not crystal-perfect video quality).
Charging something via induction (electrostatic or magnetic), as previously stated, is something that has a very low efficiency due to the 3D nature of those fields, so you've got to keep the induction coil-thing as close as possible to the monitor, which sucks since if you wanted a fully wireless solution, you basically just moved the power wire from the monitor to the inductor. Oh, and you waste ≈5x times the energy.
Charging via a powerful LASER is also a possibility, and much more efficient (although this method has its drawbacks too).

Strapping a tractor battery to the monitor is also a possibility, my 23" screen uses about 30W max. A tractor battery is 24V and about 80Ah. Doing the math gives us a huge uptime, almost a week with a full charge for a normal PC user.

Ever heard of induction?

aint gonna be efficient, and only little power will be transmitted, for example, your appliance will consume only 50watts but the power transmitter you're using is actually using about 500watts more or less =D makes it inconvenient right? its called losses, magnetic field isnt concentrated on one spot only, it spreads like the light from a flashlight, those parts that doesnt get received are lost as mere magnetic radiation, this doesnt even include that nearby metals actually absorbs magnetic fields as eddy currents.

Don't get me wrong, I understand that induction is only really usable for like charging pads(Even though it "works" multiple meters away). I was just showing TMR that there is such a thing as induction.
