Whenever I see HD TVs advertised, I will see two TVs with the same screen size, same manufacturer but three or four hundred dollars difference. Is it the screen ratio? If so, why make a TV with different screen ratios? Could the ordinary viewer distinguish between the two ratios just by looking?
Or one TV may be 768P native resolution while the other is 1080P. There are a huge variety of items that can contribute to differences in pricing for the same size TV. The differences can be a lot more than a few hundred $ too. When I was recently looking for a 40" Sony, the model prices ranged from just over $1000 to over $2500 - more than double the price for the same size LCD from the same manufacturer. In larger sizes, the differences can be even larger in $ terms. See:
