Because Monitors Display image's at a higher resolution and they have less input delay. My 3 year old monitor plays better than my 1 year old HDTV.

TV is Big, Resolution close or the same as totday monitors, the difference is the Pixel Pitch.

if you sit at a proper distance based ont he size of the tv, then it will look fine as long as your set for dot for dot resolution on the TV.

Also the way your ocnnecting it, if your just using VGA then that may be a reason for decreased quality over using HDMI/DVI

1) TV's are often really big for the resolution, giving bad pixel pitch. Think about it, each pixel on a 1080p 40" TV will be like 4x the size of a pixel on a 1080p 20" monitor. Same amount of pixels, 4x the area to cover.
2) Input lag isn't important when making a TV, so they often don't react as fast as a PC monitor.
3) Many of the "200 Hz" TV's (or whatever) aren't real 200 Hz, but merely adds extra frames to make it look smoother, making many TV's useless for 3D.

TV's are usually more expensive too, because they have things like built in speakers and coax.

Cons:
-Refresh Rates
-Pixel Density
-Input Lag
-Response time

Pros:
+Big screen
+Built in speakers..?
+TV tuner

Tvs achieve the higher refresh rate by interpolating frames. Computer monitors display the frames directly from the source eg: GPU. This is why refresh rates of 200hz on a TV is not = to 120/60hz on a computer monitor.

Then there is pixel density (better on pc monitors), input lag differences (the frame interpolation creates input lag), and lastly response time variances.

Its not that TV's are bad, and computer monitors are better, they are both purpose built. Let them stick to their purposes and you will live in harmony. TV's look great at displaying films and multimedia. PC monitors win when displaying webpages (text is smooth) and gaming.

They aren't necessarily. It depends on the TV. Most TV's have a lot of input lag but some have dedicated PC mode that cuts down on the lag. Other the that is really about the over all quality of the TV set. A $700 tv might not even look as good as a cheap TN panel on the other hand a $3000 TV might look even better then a $1500 ISP monitor. Resolution, screen size and view distance are all personal preference. To me a 40" full HD TV looks pretty darn good even closeup, well as long as the games have a healthy dose of AA.

Everyone said things that are relevant.

Biggest concerns we have as pc gamers is the response time and input lag. Those things are what FPS players are really concern about. Other games not so much.

If your talking about in terms of color and accuracy, a proper IPS monitor is going to look way alot nicer than a TN LCD TV.

Pixel density is only a real concern when you aren't gaming on the TV, because your text will literally look like trash. So when you use your TV as a monitor you will have to do alot of tweeking to get the text even bearable to look at. That is if the screen is about 30"

Wow, that was very informative--thanks for linking that! I never understood why my HTPC's output at my TV's "native" resolution never quite looked right. Darn you overscan! I really can't stand it. I've only connected via HDMI though--maybe I'll see if DVI can help curb the issue.

EDIT--I'm so glad I came across this post! It prompted me to look into the advanced settings in my new TV to find that you can change the overscan settings--and now I don't have to worry about horizontal or vertical clipping of the image from my HTPC! About time TV's are integrating settings to alleviate the issue. The previous TV (an old, god-awful DLP) didn't have anything like that.
