T400 vs T500 Screen Resolution (LED backlit)

2008-09-13, 9:54 AM

It's nice to see that LED backlight is now available for both the ThinkPad T400 and T500. 

However the T400/T500 Notebook Specifications indicate the following resolutions for the LED backlit screens:

T400  WXGA+ 1680 x 1050 129 dpi 200+ nit

T500  WXGA   1280 x 800     98 dpi 185+ nit

I'm wondering why the larger screen has the lower resolution, and also why illumination is not as good.

Are these specs correct?

The T400 you posted is a WSXGA+ screen and while the T500 use a WXGA screen. While the nit is probably to do with different backlight assembly.

Most people would not be able to tell the difference between 185 and 200 nit LCDs unless they had one next to the other...and these are not very bright at all, judging by the specs you've provided.


In daily use: R60F, R500F, T61, T410

Collecting dust: T60

Enjoying retirement: A31p, T42p,

Non-ThinkPads: Panasonic CF-31 & CF-52, HP 8760W

Yes, it's nice to see the LED backlight option available for the T500 model. I had hoped for higher resolution to match what I have on my  15" Macbook Pro at 1440x900 and it was a concern for me when I was trying to decide on which option for the screen to go with my T500.

I thought I might regret my choice but after receiving my T500 I'm extremely happy with the LED backlight option even it's resolution is a little lower. 

If one decides to place the the higher resolution screen on the Macbook Pro beside the T500 you'll probably notice the slight difference in resolution with the text and windows. But in real life I don't think you'll spend time with your head inches away from the screen studying the pixel difference. 

Even thought the LED WXGA  screen on the T500 is only 1280 x 800 I'm very happy with it.
