LCD not smooth/fluid as CRT?

My friend got his samsung 940b and i played some cs to test it out.
while the vsync is on: The refresh rate is limited to 75hz @ 800x600 rendering at 75fps and comparing to my crt monitor, over 100hz refresh rate @ 800x600 rendering at 100fps, its not as smooth/fluid as my crt.

while the vsync is off: 100fps on the lcd setup, its worse! so it looks like i have to leave vsync on for smoothness.

are all lcd's like that?

btw, he used the vga cables, (dvi cable are on the way from newegg) will dvi make any difference in smoothness/fluid?

Plans For The Future:

In the near future, LCDs, CRTs, and Plasmas will be replaced by a new tech called SED.
SED (Also called "Surface-conduction Electron-emitter Display") will offer the following specs:

(WARNING: what you are about to see could make you pee your pants).

Response times of 1millisecond or EVEN LOWER!!!
Contrast Ratio of up to 100,000:1 !!!
Viewing angles of up to 160 degrees !!!
Can scale up to 50” of HDTV viewable goodness !!!
Blacks can go as low as 0.003 cd/m2 !!!
Maximum Resolutions will be 1,920x1,080 !!!

Other stuff about SED:

-SED will also offer more vivid colours and blacker blacks
-SED uses 1/3 the power necessary to run a plasma display
-SED is expected to be cheaper than LCDs, but more expensive than plasmas
-Tohsiba and Canon are working together to bring this tech to life
-Tohsiba and Canon have made a new company called SED inc., which will be dedicated to production and manufacturing of SED displays. For more info about SED.inc, follow this link http://www.canon.com/press/p2004sep14.html
-The first 50" SED displays are expected to hit the Japanese market next Spring
-Toshiba will be producing 75,000 displays per month, in 2007

How it works:

The way the technology works means scaling up the size of the screens is very simple, as you just use bigger glass plates and more electrons.

im liking this! i'll hang onto my crt for now.

This again? It's 180 degrees.


What's saying it can't scale higher?

Nothing except for that same review posted everywhere. Most, or if not all other sources have not stated any limits, except the cryptic phrase "any size".

That 50" limit thing appears to be a rumor, or a passage was misconstrued & taken out of context...
 
Have you tried running this test in the native res (1280x1024) of the monitor? Perhaps some of the ghosting is due to the interpolated image.

Electrons hitting a fluorescent surface to produce light, so basically it's a CRT ;)
 
I have also noticed that many games need me to select "VSync" in order to have smooth framerates on my LCD, but will actually yield lower framerates overall. Does anyone know what's going on here, or if purchasing a DVI-LCD would change this?
 
This is just the nature of LCD's.

I have a 24" LCD and I have the same problem as he has. Either you have to live with the screen tearing present when VSync is off, or live with the lag time cauesd when VSync is on.
 
LCDs refresh rates dont go into the 100s. So you're never going to get what you get with your CRT. 75hz, however, will be a lot better than 60 (72hz is the VESA specified minimum frequencey for when humans dont notice flicker)
