What's the model number? The only thingy I could find was a Westinghouse LCD monitor that has 1080p. I watch a lot of standard definition broadcasts from Dish and a LCD monitor would be useless to me.
The Westinghouse is listed as a monitor, since it doesn't have a tuner built in. I assume your Dish network receiver has component and probably HDMI output, though. Both of those work on the Westinghouse.
