Hello,

I have a Thinkpad T61 7659-CTO (WXGA) with what I believe to be a non-LED screen. I recently looked into buying another used T61 or a T400 ... both of these had LED screens and I found (a) the brightness to be noticably less than in the T61 I already own, and, the white has a distinct yellow touch to it and is not as "bright white" as what I am used to. I found it to be unpleasant on the eyes.

Now, are there later models of the T400 that has a brighter screen?

And w.r.t. the new models ( I plan to buy a new Thinkpad soon), have the screens gotten any brighter?

W.r.t. "nits" or "cd/cm", what value would the T61 without LED have, or, if unknown, what value should I be looking for in a new Thinkpad to get a proper brightness? I believe that some of the new models either have 200 or 250 nits.

Can anyone shed some light on this? :)

Thanks in advance! Alexander

This may help a little:

http://i7.photobucket.com/albums/y259/m ... 110258.jpg (tried to get both to be the same brightness, left is 8/8 and right is ~8/15)
http://i7.photobucket.com/albums/y259/m ... 110257.jpg both at max brightness
the left is a dell latitude D630, WXGA CCFL screen, April 2008. right is a thinkpad T400, WXGA+ LED screen, September 2009. the LED screen is more blue and brighter, but the CCFL actually looks pretty good too.

in general an LED backlit screen should be a bit brighter than a CCFL screen.
All T61 14.1" WXGA screens are CCFL and rated at 185 nits, 300:1 contrast ratio. The T400 WXGA+ LED screen is 250 nits, 300:1 contrast ratio.
The T400s/T410s/X300/X301 WXGA+ LED backlit screen is 300 nits. Some W700/X200 thinkpads have a 400 nit screen.

for the thinkpads currently sold, most screens are 200/220/250 nits. the X series has brighter screens, and the high resolution screens are generally brighter for any newer thinkpad.
