    Hi im trying to decide to purchase on the w500 which is a wuxga ccfl backlit. Is ccfl that bad on it compared to an led. Is the screen brighter on led vs ccfl for the w500. also is the wuxga resolution too much compared to wsxga?

    Thanks

    There is no led option for the w500, both are ccfl (at least in the us)

    I can't speak from experience, but looking at the specs the ccfl is superior to the led screen on the T500 in terms of resolution (WSXGA+ vs. WXGA), brightness (200+ vs 185+ nits) and probably contrast (the ccfl WSXGA+ has 500:1 contrast, which is superior to any other screen offered on a thinkpad). Lenovo is not offering superior quality LED screens (less than 300 nits, relatively low contrast, average color gamuts) on their notebooks, probably to keep costs down as these screens remain expensive.

    Thanks for that info Paul - I wasn't aware of the contrast difference.

    I'm wondering if that is a typo regarding the brightness of the LED vs CCFL on the T500 though. Aren't LED lit screens supposed to be much brighter?

    Since I use my laptop indoors 95% of the time, do you think contrast would be a bigger factor than brightness? What's a more important feature when considering the overall quality and usability of the screen?

    Sorry for the delayed response, been very busy lately and not checking the forums. The brightness specs may be a typo since, as you mentioned, LED screens do tend to be brighter than CCFL screens. Despite that, I've tended to use my notebooks at reduced screen brightness while indoors in all but the brightest office settings (usually only when exposed to direct daylight), negating the benefits of any additional maximum brightness. It's worth noting, however, that the LED screen would provide increased longevity over its lifetime and reduced power consumption for better battery run-time.

    i dont notice MUCH difference between the X300 led and the W500 CCFL i use them both indoor

    in dark i tend to darken the LED on X300 because it hurts the eyes a little
