External TV Box - KWorld SA220

I have an extra 19" LCD monitor that I wanted to turn it to a television.

So I went to the local computer/electronic store and I found out this External TV Box: Kworld SA220. There is actually very small options of this item and I do not get any good and bad review of this brand/model on the internet, so closed eyes I get this. Anyways here is what it offers:

Enjoy analog TV and video games on your wide screen LCD monitor

Unfortunately HD functionality is not available in this model. I think it is on its SA230 model.

I have cable TV connection. All channels are good on my tv but a little bit distorted on my TV Box which disappoint me.

will post more upon completion and testing of all its features.
