Am looking to buy a LG 41 inch that supports a 1024x768 system,instead if a 1920x1080. They told me that Dish only supports the 1024x768,is this true? How much difference would I notice between the two on a plasma 3D.(good price on unit) If Dish only supports the 768,then thats all I would need. As you can,am not very clear on the subject. Need some help.
