LCD vs CRT response time?

[Flakk]

i've never even seen a response time advertised for a CRT monitor.. are all CRT's faster than LCDs? Some of the new LCD's are 16ms or 25ms.. which is fast for an LCD. Is that still slower than a CRT?

 

[bigshooter]

there is no lcd that is as fast as a crt.

CRTs don't have a response time. They have a refresh rate instead. Not really the same thing though.

ah ok.. so for gaming, crt's are the best

16ms delay is small, but in a first-person shooter online, 16ms more is still a lil bit more on top of latency to the server. unless it doesnt work the same.. but i dont see y not

16ms isn't perfect yet. crt is better optimally. u can have 100+hz refresh and color/contrast is better. that baddy hidding in a dark corner won't have his dark colors be indistinguishable from other muddy dark colors etc. you won't be limited to one resolution as with lcd.

It has nothing to do with latency to the server, nor does the response time actually measure latency.

It measures the average time taken by a pixel to change from one colour to another. Normally the figure measures black to white, (full voltage change), which is generally best case. Grey to another shade of grey, or any other colour, is generally slightly slower than the advertised response time.

The slower the response time, the slower the time taken for the pixel to completely change to the correct colour, resulting in a blurred image.

yeah i know that, but it IS a delay.. and in a game, that delay would be added to the time it takes to draw the pixels of an enemy who just popped into your screen..

I just mentioned server latency to show how a small number as 16-25ms can matter. A good ping time for me in a server is 50ms, and 80ms is noticably worse. So with a lcd with 25ms delay would make my normal 50ms ping feel like 75ms? just kinda fooling around and being curious here

Short answer - NO.

Read up a bit on how Half Life's network code works. Server latency has nothing to do with adding time to drawing characters on your screen. The code predicts where people are/will be. All the latency tells you is how long it takes to send/get the latest updates from the server as to where all the players are located and to send where you shot your gun.

In other words, it isn't going to make jack of a difference what your LCD response time is compared to your server latency as Andy already said. All a higher response time does is cause ghosting (seeing a "shadow" of the prior image on screen).

No it isn't. Screen response is instantaneous. The object is drawn with no delay. The only delay is the pixel colour reaching the correct value.

How? My friend was playing BroodWar with his LCD, in order for him to play it his LCD must have changed the resolution, no?

u "can" but its not good. lcds have pixels. can you divide 1240 into say 1024 or whatever evenly? when u display 800x600 on a 1280x1240 screen u sacrifice. you cant split a pixel into fractions. therefore the other resolutions use tricks to fit the screen, lowering quality.
