Anyone know how to watch my TV from my computer?

Are you looking to stream to your computer or just connect your monitors to a cable box? The former is possible but outside the scope of this forum. The latter depends on your monitors. What inputs do they have?

I was hoping to stream. I used to know someone who watched his Cox cable TV from a tablet and a smart phone while camping. I just was curious. Thanks.

Easiest way, if you have a computer that can run at home for capture, is to get an a/v capture device (can be small/cheap like an EasyCap, or something like a Hauppague device, with the better quality it brings) and set it up, using the a/v out from your cable box to the capture inputs.

Once that works, set up a free Skype account.  Install Skype on your computer.  Do the same thing with a free account for your mobile device.  Call the computer from your mobile, and set it to auto answer calls from that mobile account only (you can expand this later if you have more mobile devices/Skype accounts).  Use the video/audio from the capture device as the a/v for the home computer's Skype program.

Ta da.  Call the home account, the computer auto answers and gives a modest bandwidth feed of what is on the cable box.  Won't win any awards for outstanding quality, but it is quite nice when you are out and about for just passing time with a little TV.  And, the bandwidth is low enough that it should cause zero problems with any service used in the path (although, if you pay per MB with your wireless provider, make sure you compute just how expensive the feed may get--we used an "all-you-can-eat" wireless package, so it was not an issue.)

HDMI cable attached to computer and and your TV.  Very simple.
