    I'm lookin to spruce the ol girl up, and was curious: how many NIT is my screen?
    it's a cf-29ctkgzdm.

    i find, sometimes during the day, I need it to be brighter.
    Also, I had though about doing an LED swap, but wasn't sure how the brightness there would factor in (I can google formulas all day long, myself).

    EDIT
    after some further research, I've found that LEDs are alot of hype when compared to CCFL (at present). Can you increase the NIT on your screen by just replacing the CCFL????

    I have an extra lid laying around to play with.

    You can freshen it up quite a bit by putting in a new touch panel.

    You can brighten it up by removing the three layers of the touch panel and using clear plastic/glass instead.

    Max 500 nit. May be lower not sure here.

    You can buy one of these 1000 nit CF-30's I've got. :D

    And you have seen this I'm sure. http://forum.notebookreview.com/6067167-post1.html

    So where does the Nit come from?

    Not being a total idiot, I can surmise that it is a combination of how bright my light is, with how dulling my screen is? yes?

    SO, one could postulate that upgrading the ccfl to a higher nit (or LED) would suffice.
    Will the 1000nit ccfl fit in my 29? But then has to compare oranges to oranges: it may be that they just decreased the dullness of the screen to increas nit in the 30's?
    thoughts?

    I just copped a new ts glass, kb, hdd, and feet.
    oh, how nice it will be to get my touch screen back!

    I found this interesting:

    calling cd/m2 ``nit'' when needed

    Is it correct? I think so but, I'm not an engineer.

    It certainly sounds correct. I know how irritating "knots per hour" is to us nautical types.

    Yean, I got one. But it isn't 6000 nits. It's about 1000 nits of backlighting and around 5000 nits maximum that the sun can provide when shining bright on the display.
    It's easy to explane. If you have a regular screen it usually maxes out around 350 for a cheap laptop and 500 for a more expensive laptop. If the sun shines on that display, you don't see anything because the sun can give something like 5000 nits (I'm not sure how much google or wiki it if you want to know) so the regular screen looses big time as 500 is no match to outshine the sun.
    The transflective screens have a kind of mirror behind the display that reflects the 5000nits from the sun and it tops it up with 1000 nits, so it can be "brighter than the sun".
    Bottomline is that it works quite well and although I haven't had a real summer-mid-day-sun to shine on it, I never had to make it brighter than half way. Full brightness is often too much light and not comfortable!
