Does LCD make you work slower?

i've got a CRT recently and everytime on it my work speeds up somehow i'm clicking through things faster and going through material faster.

everytime i go back to the LCD it doesn't work quite as fast.

why does that happen? larger resolution on the LCD? smoother CRT experience? can only guess.

have you noticed this?:D
 
one way to compare this experience is like moving from a dialup to a broadband connection. smoother faster work.
 
maybe it is the same feeling as moving from 60hz lcd to 120 hz lcd? i'm guessing because i havent used a 120hz lcd so far.

I believe that it has something to do with motion blur -- tracking your eyes on moving mouse pointer, moving windows, reading while scrolling text, etc. are all easier on CRT than on LCD due to motion blur.

That's because LCD displays are continuously shining (sample-and-hold display) while CRT are flickering (impulse-driven display), and your eye tracking motion creates some motion blur. Pixel persistence contributes (~2-5ms) too every refresh, though eye tracking motion blur is more major as that adds 16ms of motion blur per frame. As a frame (of a moving object) displays statically between refreshes, your eyes are still continuously moving in the same direction of the motion. (Note: Even if the eye is not perfect at tracking objects, the eyes are still continuously moving during a whole refresh.) That retinally blurs the static frames -- the motion blur is the distance of object movement between frames. (References: One example simple diagram of eye tracking motion blur is Page 4 of this Sony presentation, another one example advanced scientific reference (load the full paper), and more references here)

Here's sample tests to try on LCD versus CRT:
1. Try to scroll a web browser window (using smooth-scroll) while trying to read the text.
2. Move a web browser window around while trying to read the text.
3. Move the mouse pointer around on a blank screen (white window or black window) while trying to track your eyes on it.

You'll quickly see that motion is much sharper, clearer on CRT than on LCD.
Less blurry motion on CRT.
In these situations, your eyes are a little ahead (where they need to be) on a CRT, than on an LCD, especially when things are in motion.
More reading done, your eyes further along than they would have been, your eyes already on the mouse cursor because it was easier to follow, more work done sooner. All those seconds add up over time, for SOME people. Others get more work done on LCD because they find the display more comfortable (flicker-free), but clearly, you're not one of those people...

There might be other factors, but I think this one is the biggie.

Unless the LCD you are using has a high input lag, and I mean really high, and you to do a ton of mouse clicks/movement, I don't think most people would say their LCD makes them work slower.

Motion blur could be a factor, if you are watching a lot of videos or fast moving things for some reason. But for normal work stuff, I don't see how it really matters. It's not like you are reading moving text (or at least most people don't).

The only logical reason I can really think of for work to be slower on an LCD is simply the size of the screen. If working on a 17"-21" CRT, the workspace will naturally be smaller than a 23"-27" LCD, and you will have to move your mouse more to cover the same space on the LCD. If that is the issue, easy way to fix that is simply to speed up your mouse in win settings.
 
CRT monitors KILL my eyes and honestly probably slow me down as I am always noticing imperfections and clarity issues, as Namelessme said play with your mouse settings, helps a lot.
 
motion blur and mouse speed... probably right.. i'm comparing a 22" TN LCD vs 21" CRT. the resolution doesn't make a difference, the crt is just faster at the same mouse speed between the displays.
 
its probably some x factor. things feel more alive and snappy on this display (crt). its like the LCD has got some fatigue.

lol yeah? only lcd i can tolerate is a Apple cinema 27". i'm guessing you've not used good high end CRT in prime condition.

Sounds a lot like input lag to me, but I wouldn't think a TNer would have much in the way of input lag. Unless you just happen to be sensitive to the smallest amount of lag.

As for CRTs vs LCDs, everyone has different preferences. I have used high end CRTs before, and their text won't be as sharp as a good LCD. Just the way it is... They are great with some other things, but font sharpness isn't one of them. So that may bother some people, just the way lag seems to bother you.

you can make the text acceptably sharp by changing the resolution on the crt.

its pretty sharp till 1920x1440, but lower if you want it bigger.

im not sure if its the lag or response time since its a TN panel, probably the hz.
 
for me its mostly the refresh rate
i find moving the mouse at 60hz so exhausting that i can't even use it for coding

lcd blur is another thing...
but i feel it only slows down my workflow (3d modeling etc) by 10-20%
and it doesn't really exhaust me
