Q. I've just bought a Samsung 2233SW Widescreen LCD monitor, and i'm wondering why games can't seem to display at 60fps when i'm turning my character in Call of Duty 4 for example. Everything else like running forwards or sideways, and even the other soldier's motions are 60fps but specifically when i'm panning the camera, there's a stutter. Even if FRAPS clearly shows framerates going way over 100fps in those instances. Before i upgraded my monitor, i was enjoying silky smooth 60fps or higher framerates on my CRT monitor, no matter what i was doing onscreen.
Is there a limitation to LCD monitors that i should know about? that even though the PC is churning out 60fps, the monitor displays significantly less than that?
My rig:
Core 2 Duo E7200 2.53ghz
2GB Ram
8800GT 256MB DDR3

A. LCD monitors do not refresh like a normal CRT monitor does.
A CRT monitor refreshes the whole screen based on it's refresh rate, which usually is 60hz or 60 times a second.
LCD's refresh individual pixel changes, and the speed of that refresh is based on the monitors response time. Which for your monitor is 5ms.
That is why you are noticing the stuttering or screen-tear that you speak of.
Most monitors built for gaming have a sub 5ms response time because of that exact issue. Some people cannot tell the difference between 6ms and 4ms, others can.

Whats the best way to clean a LCD computer monitor?
Q. I have a Toshiba Qosmio laptop, with a 17' LCD Flat screen and Im not sure how to go about cleaning it. Should I just use windex and a paper towel like I would on my TV, or is there a special way to clean LCD monitors?????
A. Cleaning Your LCD Screen
The major computer outlet stores are now starting to carry LCD cleaners for Flat Panel Monitors and Notebooks that do not contain the chemicals found in some commercial glass cleaners. These cleaners will definitely do the job nicely, but you do have to purchase them. If you do not wish to purchase these factory made cleaners, then you can clean your LCD Screen in the following manner.
What You Can Use
Water.
Water with a tiny amount of soft liquid soap.
Isopropyl Alcohol.
Hexane.
Petroleum Benzine.
Commercial glass cleaners that do not contain ammonia.
What You Should Avoid
Acetone.
Ammonia.
Ethyl acid.
Ethyl Alcohol.
Methyl chloride.
Toluene.
Commercial glass cleaners containing ammonia.
How You Should Do It
You should clean your LCD Screen display by applying the cleaner to a soft, clean cloth. Then you should wipe the cloth across the display from left to right, moving from the top of the display down to the bottom of the display. If your display contains grease or some other contaminant, then you should dampen your cloth with water instead of a commercial cleaner as the cleaner may smear the contaminants across the screen.
