Speaking of Plasma sets, I keep reading in reviews that they're NOT going to compare the LCD sets against the Plasma sets because Plasma is still the far-and-away leader in THIS category or THAT one, BUT when I see them side-by-side with various Plasma sets in the stores, in almost every case, the Plasma sets don't look as good as the LCD sets... For one thing, they look A LOT darker. I realize they have a disadvantage in a brightly-lit location, such as a well-lit store (and I'm talking mostly about the showrooms of Sam's Club and Costco, which ARE brightly-lit, unlike the TV areas in Best Buy, which I don't shop as often). I DID see a 58" Plasma set in Sam's a couple days ago that looked pretty good, although still a bit on the dark side, but I still don't "get it." For the most part, they also seem to not have as crisp of a picture, either. And they certainly are much bigger power hogs, heavier, have a greater risk of breakage with GLASS screens, the problem of dimming over time as the gas they use diminishes in usefulness, etc. I can't IMAGINE the circumstance where I'd buy Plasma over LCD or LED, personally.
Thee, you might have a chance to watch some kind of sports before next Saturday -- isn't there some night-time sports before then -- or something else? Sounds like you're watching just over-the-air broadcasts, else you could doubtless find other sources between now and then.
And I see where some of you may be having issues with 1080i that may disappear if you watch in 720P, which I BELIEVE is available on any broadcast that also uses 1080i. My preference, when both are available, is always 720P, since 1080i, even though it IS 1080, is still ALSO an INTERLACED signal, meaning that if it were slower you'd see the "flicker" that used to be commonly seen whenever we saw TV signals or computer monitors on TV programs or in movies back in the old days, before better, higher-resolution and non-interlaced monitors were developed... Remembering those days, I'm still not a fan of ANY interlaced signal, even at 1080, which is why I have never used that setting.
I'd suggest that those of you who have your TVs set up to display at 1080i and are having issues with quality try temporarily switching all display modes to 720P and see if THAT makes any difference. It might not, or it might not look as good -- or it might look better... But it's probably worth a little experimentation. Frankly, I haven't even checked to see what the options are, or what mine is set to, but if I start having issues, I will.
