Computer signal fuzzy on 50" LCD

Hello Everyone, I have been struggling with a problem that no one can help me on, I have read things but no one explained it clearly yet.

I use my LCD 50" Panasonic 1080i TV ( 5 years old ) as a clone of my ASUS 22" 1080P LCD Monitor. I have a pretty good video card with a max resolution of 2560x1600. Here is a link to it if it helps.

The computer signal on my 22" is very crisp at full HD, but on my TV the letters are hard to read, blurry or fuzzy. I have both signals outputting at 1920x1080, both are connected through DVI connections. I use the TV to watch movies from my computer on a larger screen. The movies look great, just like on the 22" but reading text from any page really hurts my eyes because it's so fuzzy, readable but not comfortable to read.

Does anyone know how to solve this? I don't want to buy a new TV, because the picture from cable is excellent.

Thank you for any help.

It's probably got something to do with the fact you're cloning 1080p onto a 1080i screen. 1080i i believe is only 30 hertz, where 1080p is 60 hertz.

Try hooking your TV up to the computer alone. And check your graphics card's control panel for and TV output settings.

Is it a projection TV? If so, your scenario is very common. You'll have a challenging time getting crisp text at that resolution on anything outside of an LCD-based (LCD projection should be fine and sharp) or plasma (which is generally thought to be a no-no as a computer monitor due to burn-in susceptability...).

My TV is a LCD projection.

Most HDTVs I have seen that say 1080i actually have a native resolution in the area of 1360x768 or 1280x768. I would try that res and see if it looks better. usually the best looking display id when the resolution is set to the native resolution of the display.

The windows font was not designed for large screen TV's and does not scale properlly when using windows XP PRO. I am now using Vista Home Premium 64 bit on my game machine and have no problem reading the text on my 65" DLP Mits HDTV. and games look great

Do you have a 1080i or 1080P TV? I have vista that I didn't install yet, I will try that when I have some time. Thank You for that.

A friend had the same issue, except on a 32" TV. He didn't know the difference between 720P and 1080i. He thought higher was better because one of his less educated friends said so. The text was really blurry and I had to strain my eyes to read it. I had him switch it to 720P and the problem was solved. i = interlace=30FPS and P=Progressive=60FPS.
