I've been looking for a wireless adapter that will allow me to use an old TV for a computer monitor. The adapter would have to output to the audio and video RCA jacks. It's a good TV, just a little dated on the inputs.
OR if it's more cost effective to just buy a wireless monitor with built in speakers and volume control, I would consider that.
The plan is to start a movie on Netflix and then dash downstairs and watch it while spending some quality time on the treadmill.
