Basically what does the ms part stand...i know vaguely...but not fully..i can either choose a 17inch lcd with 8ms/6ms response time or 19inch crt...which one?
 
I have a 12ms LCD(Sam.712N) and a 19in CRT(NEC Fe991sb) and I like gaming more on the CRT because it looks better, but if you LAN alot LCDs are great.

So if you LAN allthe time go for the LCD but if not I would choose the CRT.
Oh yea, the MS thing is the time it takes to switch from,usally, grey to grey.....at least I think. The lower the better.

"Response Time is an attribute that applies to LCD monitors. It translates to the amount of time it takes for a liquid crystal cell to go from active (black) to inactive (white) and back to active (black) again. It is measured in milliseconds (ms). Lower numbers mean faster transitions and therefore less visible image artifacts. Older monitors with long response times would create a smear or blur pattern around moving objects, making them unacceptable for moving video. However current LCDs monitors have improved to the point that this is rarely seen."
-Wikipedia

They say black to white then back to black but usally the advertised time is grey to grey.
 
Personal taste to determine what you'd prefer at 17" or 19". Are they identical in all other ways (brightness, contrast ratio, connectors (DVI, D-Sub, both, S-Video). . .?

I like 17". I can see the pixels too easily with a 19" monitor, and I like being able to see everything without having to move my eyes around (waste of time when you gotta shovel bitches).
 
lol..thnx for the info guys...but sum1 said in a thread that depending on the ms speed it can only go to a max fps without becoming blurry?..so what would 8/6ms get blurry at?

Above 125 FPS

You wont see this much in FPS games.

8 ms is 8/1000ths of a second.

1000 divided by 8 is 125.

You could ask an 8ms monitor to refresh 125 times a second.

LCD response time and refresh rate are apples and oranges. It takes LCD with 8 ms response time full 8/1000th second to gradualy change from black to white to black again. It does not mean it can blink 125 times a second. Faster response time is always better even at low refresh rate because the eyes still see the gradual change of pixel. You don't need higher refresh rate than the response time to tell the different.
 
response times come in two flavors.

1) Black to White to Black, often referred to as "true" response time. This is what the first LCD's used to measure their response time. 25ms was common a year or so ago. Now 16, 12, and 8ms are easy to find.

2) Gray to Gray, this is a newly adopted response time which makes it easier for manufacturers to fudge their response times. They can cut corners to make the GtG response time very fast, yet true response time will be much different. From what i have seen, GtG response time X 2 or X 2.5 is usually about the true response time. GtG is pretty much used as a marketing tool to make their LCD's seem faster cuz most people dont realize they they are comparing apples to oranges when they say "Oh ya, this is a 4ms or 2ms panel and is lower than the 8ms over there" when in actuality they will be very close and the 8ms will sometimes be faster.

Do your homework! Do not be fooled!
 
isnt a 17in lcd equivalent to a 19in crt since the lcd is measured by viewing area instead of the physical size?
 
I would go with the 8ms response time LCD over a 6ms response LCD or a 19" CRT. Why?

8ms is believable to me, whereas 6ms means to me they fudged a bit on the Gray to Gray. Don't know if this is true or not, as it would depend on the specific display, but that's just how I view it.

If you work with text at all for a significant portion of your computing (i.e. email, websites, etc.) I'd strongly recommend LCD over CRT. It looks so much better. IQ ftw
 
kk...thnx for all the information :)

ill search for a good lcd in my prcie range (£180) and then comeback with my choices so you guys can tell me which one is best..thnx

Err, no. It doesn't work like this at all. Ghosting has nothing to do with the frame refresh rate, its affected by frame delta differences. An LCD monitor won't show ghosting on a static image, no matter how how many FPS that image is being refreshed.

Now, back to that 8ms response time. Imagine a an object moving across your 1600-pixel wide screen. If it takes 2 seconds to cross the screen, its moving 800 pixels/s. Or individual pixels are being updated in 1.25ms. So any LCD with a refresh time higher than 1.25ms will show ghosting with an image changing at this speed.
 
so basically even a 2ms lcd screen will show ghosting?

is ghosting apparent when playing games...becasue my crt screen is amazing right now and its 18inch viewable even though its 19inch
 
i can see ghosting...and i think crts dont have ghosting cause their refresh rates are so much lower than lcds (under 1ms?)

Under extreme conditions, yes, such as white text scrolling quickly on a black background, or very fast motion. CRTs have response times well under 1ms (with normal phosphors, that is), so they don't normall exhibit ghosting.
 
...will i see ghosting whilts playing games like fear/cs:source/hl2/doom3/far cry etc? and will it be evident?

Impossible to say. Some people don't notice it; others are driven crazy by it. The -average- person, though, will notice very little ghosting on an 8ms monitor, except possibly in the extreme cases I mentioned.

what about u? do u notice them?

Me? Very rarely.

For me, the worst part about LCDs for gaming isn't ghosting, but rather the poor black levels. A 1000:1 contrast ratio is pretty much my rock-bottom minimum...and even here, the shiny-grey blacks and lack of shadow detail annoy me. I have 2 LCD monitors I use for text work...but I break out the CRT for movies and games.
 
basically a good contrast is needed then :p thanks this will help me...anyone know a good £180lcd?
