Not quite sure what you mean there
Often LCD TVs are shipped with cheaper, lower resolution panels. You mentioned that you wanted panels with a lower native resolution - these panels have a lower native resolution
Due to the inherent low resolution and poorer quality of TV signals having a low native resolution on a TV panel can actually be beneficial as it avoids scaling and it avoids focusing on the imperfections in the signal
When you display a standard output from a computer (eg the Windows desktop) the quality displayed is rather poor, hence my comment. I'd therefore say that having a low native resolution when used for windows work is a bad idea. You really want to have a higher native resolution as the pixels are smaller giving a better image
