When looking @ a crt device, my tft seems blurry to me

never seen that either, only restriction i've seen is 75Hz can only be used in VGA, locked to 60Hz in DVI.
As for the refresh rate vs. response time thing, I dont know. To update pixels in 2ms would require 500Hz refresh rate. Maybe it just means that on a 16ms monitor, it constantly lags behind the input by 1 frame. Either way I can't tell the difference between my old 16ms monitor and my new 5ms one.

There is no benefit, absolutely none, in running a tft at anything other than 60hz. Setting it to 75hz will not allow the display of 75fps, it will still be 60fps. Just because you input a 75hz image to a tft it does not mean the output will be 75hz!
Regarding the response times, using your 16ms example, it is certainly not ideal for a display to be in a state of transition for a whole 16ms between frames, the image would be unrecognisable. We need to see a nice and sharp static image for 16ms, then another nice and sharp image for the next 16ms with no state of transition. Hence the lower the response times the better. Lag has very little to do with response and more to do with image processing.

In my nVidia toolbar it allows me to set it to 75Hz and the Monitor says it can, is it a DVI limitation?
The signal you are sending to your monitor is 1440x900@75Hz
The output your monitor is displaying is 1440x900@60Hz
The image processing in your monitor prevents the input refresh rate from exceeding the panel's capability (all consumer panels are 60Hz). A 60Hz input will update pixels 60 times per second, a 75Hz input will update 60 per second, anything more will result in 'out of range' or similar as the processing is not 'compatible' with higher than 75Hz.
Just because a monitor 'supports' or is 'compatible' with 75Hz doesn't mean it outputs at 75Hz.
Set your display to 60Hz and be (mildly) amazed by the increased clarity and motion smoothness.

gonna need some proof for that. but anyway, my point was that atft running at 60ms wont display anything any quicker. reponse times may be falling yes, but you wont be displaying anything from the card any quicker. most 16ms display or under and pretty much fine anyway.

From what I've read TFTs always work at 60 Hz internally, so even if it's set to 75 Hz, it's just converting the signal down to 60 Hz (presumably either by skipping frames or interpolation - hence why 75 Hz can sometimes appear blurry).
First thing I notice when I sit down at my parents PC is how much softer the image is on their CRT compared to my TFT. I find it odd that anyone would find a TFT blurry after using a CRT. Hence why people are asking if snowdogs TFT is using native resolution, and suggesting he uses the TFT at 60 Hz. Also '1280' is not a resolution, and we don't know whether the TFT is widescreen. Without more information it's impossible to say what the problem could be. Model number should be on the back of the screen somewhere.

About a third of the way down the article.
So to everyone who has set their refresh rate to 75Hz, get it down to 60Hz!!!
