Ok, let me answer you question as clear as I can
When you watch television, it doesn't require you site real close to the screen, right? The CRT televisions have small pixels, but not as close as a computer monitor pixels. Compare both, as you can see, the television pixels are much bigger than a computer monitor pixels. That is because a computer monitor requires you to read small images, unlike a television, in which you can site back. That is why computer monitors cost more than most television sets (CRT). A 17 inch CRT is around 100 bucks, compare that to a television, which you can get a 20 or 25 inch set. That is because the computer monitor has to squish all those pixels on to that little screen, unlike televisions. That is why you can;t read small text or images clearly on televisions.
Projectors are different. They have the same basic platform as regular LCD monitors, except they have a stronger bulb which powers them.(LCD Projecter)blah......... The have no relation on how the standard TV displays things.
Now television monitors are different. Because they allow more pixels to be installed into the screen, though not as clear as computer monitors, but still, better than standard televisions.
Now if you want to see your computer screen clearly on a televsion screen, then I suggest you get a LCD television.
There is no way to make your text clearer on a standard televison set, besides changing you res.
Hope this is clear
