Standard definition video is 480i: it has to be deinterlaced (ie, turned into progressive video) in order to be displayed on a digital display. Proper deinterlacing costs money, though that cost has come down a long way over the past decade.

Scaling would seem to be an easy task, but often times the inexpensive scalers, which are usually off-the-shelf multi-task chips, just aren't up to the task.

Combine the two and you've got the ingredients for a terrible display of SD material. You also have to consider the fact that the manufacturer is going to put the most money into the parts inside the display that make High Definition look the best (it is, after all, an HD display), not polishing up lower resolution material.
