my new 19" LCD monitor can support like 75 refresh rate, and com_maxfps 125 makes it look/feel like crap

Is it normal to have a slow motion effect when playing Q3 ?

I had a old skool CRT monitor and never had this problem

Are there any settings im missing ... ?

LCD Monitor FPS Question

lcds have a higher reaction time then crts, 2 ms is quite playable, but i wouldnt play on 4 8 or 16 ms reaction time (time the lcd needs to change color)

u might try dual lineup

LCD Monitor FPS Question

Modern LCD's on S-IPS or TN matrixes are not crap.We are having a similar discussion on lem private,dont forget some manufacturers state one response time and when a group of experts measure it the response time is actually much higher.In other words,some manufacturers are using false advertising.

Here is one good review of LCD monitors:
http://www.xbitlabs.com/articles/other/display/20inch-4.html

Personally Im considering to switch from CRT to LCD,so far I ran into only one obstacle.U are "limited" to the native resolution,which is in case of 20" 16:10 ratio monitors 1680x1050.So to play newer games for example on that res u need a high end pc and a beast of a gfx card that will support that res in the first place.U can lower the resolution but it will either look crap or with black edges on the sides cause of the smaller pic,the screen space will not be filled 100%.

what are u taking about? all is about refresh time max on lcd is 75 hz (75 time per sec) crt can get 120 hz.

the chemical process of a pixel for changing color after the frame reached the lcd is either 2 ms 4 ms etc
thats called reaction time.
sure, if u have 75 hz monitor on 4 ms, it can be smoother as 60 hz with 2 ms etc.
anyways, crt can get way above 120 hz, i just use 60 hz, works pretty bad x)

LCD Monitor FPS Question

Taken from wikipedia:

Much of the discussion of refresh rate does not apply to LCD monitors. This is because while a phosphor on a CRT will begin to dim as soon as the electron beam passes it, LCD cells open to pass a continuous stream of light, and do not dim until instructed to produce a darker color. Pertaining to LCDs, see also response time and Input lag.

Input lag is a phenomenon associated with some types of LCD displays, and nearly all types of HDTVs, that refers to latency, or lag measured by the difference between the time a signal is input into a display and the time it is shown by the display. This lag time has been measured as high as 65ms, or the equivalent of 3-4 frames on a 60Hz display. Currently, the only TFT panels known to have this phenomenon are so-called overdrive panels. These include S-PVA, S-MVA, and Overdrive-TN panels. S-PVA have been observed to suffer from greater input lag than P-MVA panels, while IPS, S-IPS and AS-IPS panels are not or only minimally affected.

Connecting to the last line,it confirms the first line in my previous post which I wrote before I read this Happy

nope Winking Look at history of LCD displays and transistors. BTW 2ms and others values are gauged only on grey colors. If youre using colors, this times will be higher Winking Good manufacturers of LCDs are AG neovo and maybe LG i think. I dont recommend samsung, asus and acer

Apple Mac mini M4 + Apple Magic Keyboard + Logitech G603

It's "response time" and it's not at all higher than a CRT's one. A CRT has around 0.86 ms in response time whereas LCD screens haven't beaten 2ms. Plus you can't compare response times between a CRT and a LCD monitor because of the different kind of technologies used. A CRT displaying a movie with even 12ms response time would not make you "feel" anything wrong whereas doing the same thing on a LCD would instantly make you notice a blur. Even if LCD screens get to 1ms you would feel (more or less) the ghosting on them.

So to sum this up, CRT still rules for gaming.

LCD Monitor FPS Question

1. bluring is caused couse of pixes color change in LCD monitor, they just ned way more time than CRT do, 2ms is quite playable but [...]

2. refresh rate of LCD monitors are limited to 75Hz it means LCD display is able to show framerate up to 75fps withnout spliting the scren while animation on it, u can play q3 on 125fps but while moving screen will be splited on half due 2x to higer framerate than 75, u notice it when screen animation change quickly ad u wont notice it on stable scene

3. angles of visibility, all LCD monitors change colors depends on wahat angle u will look at it, some les some more, u might get used to it but on CRT these negative thing dosent exist
