Response time

[Biges]

Hi!
I'd like to ask some questions regarding the response time of LCD panels:
1) How often is the value given by the manufacturers correct? Are there some cases, when the given values are really much lower than the real? And, however unlikely, are the the opposite cases?
2) How important the value really is in movies and games?
Thanks

have a read about response time here: http://www.tftcentral.co.uk/specs.htm, should help :)

As long as the spec is 16ms or below, and not 25ms+ like some old-school or professional graphic LCDs are. You *should* be fine for games and movies.

Though some people seem to be more finicky about it than others *shrug* just depends on how anal you are.

I bought a Acer P223WAd 22" Widescreen LCD. Has a 2ms response time and glossy screen, works great.

For monitors i would go as low as possible for response time.

For monitors i would go as low as possible for response time.And you'll end up with a TN panel with very poor dark and light color reproduction and a game like Doom3 will be virtually unplayable. :( I've suffered that scenario with a Samsung 19" TN panel.

I went from a TN monitor with low(er) response time to a *VA with (supposedly) worse response time. Can't tell the difference, no discernible lag effects in either. I don't twitch game, but I do play other types of games (Oblivion being the most effected by response time) and watch movies. Not bothered in the slightest by the worse response time, and in fact can't notice it at all. OTOH, I'm much more pleased by all the benefits of a *VA monitor, better colors (true 8-bit instead of dithered 6-bit) and contrast most of all.

There will be lots of people on both sides of this, so I would urge you to try to figure this out on your own. Go to a store that has a monitor with more response time, and see with your own eyes if it bothers you, or if you can even notice it at all. If not, then remove that from your criteria unless you're an online competitive FPS gamer, in which case just stick with a CRT. ;)

Also be careful with the matte vs. glossy aspect; glossy looks great in stores, but IMHO a matte is far preferable at home, especially if you're not a hermit and actually like the sunlight streaming into your room. Some people love glossy though, regardless. Another area to not listen to people and just decide for yourself after researching the objective pros and cons of both.

Thanks for your opinions.
I tested a few monitors and I think *VA is fine for playing games (and I really noticed no problems with movies). In an unlikely case I'd be froced to play something really, really demanding, I can use my 19" CRT :)

My Acer is 2ms response time and works great, glossy screen improves color plus, if you have dark colors, change contrast or brightness ;)

besides response time, there is also input lag, two different thing. its not important to movie, but it matters in online games.

My Acer is 2ms response time and works great, glossy screen improves color plus, if you have dark colors, change contrast or brightness ;)It has nothing to do with contrast/brightness. When your working in various shades of black and dark gray, the 6bit per channel TN panels cannot produce the colors correctly and you lose lots of detail. Contrast/brightness/gamma adjustment cannot fix this.

I don't like glossy screens, if I want to stare into a mirror I'll go into my bathroom. If I want to see what's behind me, I'll turn my head :p

I find response time is a bit of an overrated specification.

Usually the manufacturer will give you the lowest number they can. VA panels are not as good in regards to response time for dark colors, but are excellent for mid-shades to lighter colors. TNs are good all-around, but because they are 6-bit and employ HiFRC and dithering to approximate colors. S-IPS are better than VA but not as good as TN, but their response time is not as dependent on dark to light or dark to dark shifts as VA.

TN panels are the fastest, but I prefer the 5ms ones without overdrive. I don't find any real difference between 2ms and 5ms panels, as the 2ms panels employ overdrive which can cause input lag due to extra frame buffering.

Thanks for the answer. I really don't consider getting TN, as their colors are less then adeqate for my demanding tastet :) So far I have that borrowed LP2465 :)
