It's not worth worrying about. You don't WANT to see levels below black anyway, When you have properly adjusted the brightness control, you won't see any information "below black". If you CAN see information below black (on a TV that doesn't clip black at digital 16), you will get blacks that aren't really black so you'll essentially raise the black level of the display. The whole PLUGE thing exists only to make sure your black is set to the darkest level the TV can produce. If you can't see the 4% below black bar, it's really not an issue. For your TV, just lower the Brightness control until the 2% or 4% above black bar is invisible, then raise the Brightness control 1 or 2 steps to make it visible again. For TVs like yours, a better pattern for setting the Brightness control is a digital levels pattern with values from, say 16 - 25 or so. You can then easily find a Brightness control setting that makes 16 black, but causes 17 (or maybe 18) to be JUST BARELY visible in a completely dark room. That would be your best Brightness controls setting.
Patterns like that are less common than the more coarse PLUGE patterns that appear on just about every setup disc. I don't have any disc titles off the top of my head where they have a digital levels pattern like the one I described, I use the one in my video signal generator so haven't needed to look for on on a setup disc. Perhaps someone else will have a suggestion. But for now... make the 2% or 4% above black bar disappear (too dark) then raise the Brightness control 1 click at a time until that step is visible again.
