Seeking good/best T400 display for outdoor/direct-sunlight

[hydrostarr]

I'm seeking a good/best T400 display for outdoor/direct-sunlight viewing.

Looks like I've found a reasonably-priced T400 with a LG-Philips LP141WP1-TLB8, FRU=42T0579 (not quite a LP141WP2-TLB1, but still an LG...for whatever that's worth...and I've been told by another source that LG-Philips tend to offer better-quality displays...alas, this may be personal preference?). 220 nit according to http://www.thinkwiki.org/wiki/TFT_display .

Any comments on this (LP141WP1-TLB8) display? Would this be my best T400 option (aside from upgrading any T400 to a LP141WP2-TLB1)?

I'm not sure, but I'm reading that the LP141WP1-TLB8 might be a CCFL/backlit system, instead of LED backlit. Is one technology necessarily "better" than the other for this application? And/or does the CCFL present a potential problem for my outdoor/sunlight viewing, battery drain, or anything else? (Battery is also quite important for me, but secondary to the sunlight viewing...)

The biggest factor for well a screen works outdoors is the brightness of the screen, the brighter the better. The T400 was offered with a high brightness LCD, about 3x brighter than the typical notebook screen. It's a Samsung screen, part number LTN141AT09. If you can find one of those or do the swap yourself, that's your best option to use a T400 outdoors.

Yeah, great point. I see this LTN141AT09 listed as a 680-nit screen on http://www.thinkwiki.org/wiki/TFT_display . 2 problems I have with this display: 1) it's a 1280x800, and I'm concerned that resolution would be too small, and 2) I can't find this display sold anywhere (everyone's out of stock that I've seen), although I haven't looked that hard. I'm wondering if the aforementioned 1440x900 screens are good enough for a bright display, eg: http://forum.notebookreview.com/what-no ... ost6569712 .

I'm still wondering about the following display, if anyone has any comments?

My X200 is about 200 nits and doesn't do real well outdoors. Is an extra 100 nit enough? I don't know as I've never seen one. I did see one of 680 nit disaplys on ebay last month. I think it was running about $125. Perhaps you just got to wait it out. As for the resolution, I guess you can't have it all. Scrolling works well on the point stick. I don't mind the WXGA on my X200.

Hmm, good to know.

I'm specifically seeking thoughts on the pic found here:

The T410 is just so much more bright than the R52 next to it (which is same brightness as my "new" T60p). I'm not trying to buy said T410. But I think the question might boil down to: if the T400 I'm looking to buy (all the details above or at the aforementioned link) has a similar brightness as the T410 in the above pic, then I think I'm gonna be good.

Thoughts?

A lot of the dimness could be attributed to the fact that the R52's backlight is five years old, perhaps not. My R60 was about a year and a half old when I got my X200. Both were rated at 200 nit, but the X200 is significantly brighter and I don't think the R650's display was ever that bright when new.

Another good point to know.

Also, if the T400 model I seek is CCFL backlit (vs LED backlit), could that present any particular problem/challenge for brightness, battery drain, life of display, etc?

Another point: a used 220-nit display (LP141WP1-TLB8, with its supposed CCFL backlight that wears out sooner than LED backlights?) may or may not be as bright as a new 200-nit display (FRU=42T0597, an AUO B141PW03 according to http://www.thinkwiki.org/wiki/TFT_display ), the latter is another option I have to buy.

Thoughts?
