It strikes me that a lot of the difference between one plasma or LCD TV and another at in-shop demonstrations is probably down to differences in the video processing circuitry. Specifically in the abilities of the screen's in-built deinterlacing and video scaling. However, the chances are than an external scaler/deinterlacer will do a better job, if you're prepared to spend enough money. So, this raises two questions, the second of which is probably the more important: 1) Can one save money by buying a screen that actually doesn't have its own scaling and deinterlacing circuitry at all? 2) Is the answer to the question "which screens have the best image quality for the best price?" going to be different if you know in advance that you're going to be using an external scaler/deinterlacer than it would be if you're depending on the screen's own capabilities?
