Hey I am currently using this tv as both my monitor and tv.
It has no internal tuner. I wanted to buy a usb tuner that would give me the highest quality OTA HD local channels. In addition to this (and I don't even know if such a thing exists) I want that tuner to also have the ability to plug in a standard cable plug into it and I would be able to get regular cable through it as well.
I have no internal tuner on the TV so I don't know if such a thing is possible without a big cable box from the cable company. Here is the one I was looking at:
Does it do both of those things?
