T400- WXGA+ "High Nit" LED option...info?

One day in the last week, a new display option appeared for the T400. The base display is the WXGA (1280x800) with CCFL backlighting and the two options are a WXGA+ (1440x900) CCFL or WXGA+ (1440x900) with LED backlighting. But at least for one day, there was yet another option (priced at $150, if I recall correctly) for a 14.1" WXGA+ (1440x900) "High Nit" with LED backlighting. Unfortunately, it has vanished from the options list now???

Both of the CCFL-backlit versions are 185+ nit displays. The existing WXGA+ LED option is a 200+ nit display.

So I have two questions- what happened to the 'High Nit' options? Will it return and, if so, when? And is it a 250-nit display or perhaps even 300-nit???

FYI- the ThinkPad X200s uses a 250-nit display and the X300/X301 have a 300-nit display standard. The SL300 also benefits from a super-bright 300-nit display.

 

Same issue as in this thread, I think.

It could very well have been a typo, given Lenovo's inclination for such mistakes.

 

I am guessing that a high-nit option will be offered shortly.

I've noticed that when Lenovo adds more options they are live on the site sometime before they are available for purchase and then they are taken down. I've seen this happen with processors and hard drives. Shortly thereafter they are available for purchase.

An additional clue is that 200 nit is *not* a high-nit display. It is average at best. The reference to a "high nit" display cannot possibly be the current LED backlight.

I think this is what you are looking for. I don't know the details but there is a high-nit WXGA LED screen.

Search for 6474R8U on the page.

 

Similar to the way they've had the Intel GMA X3100 listed as the GPU on the IdeaPad Y430 for over a week now....but their downloaded spec sheet (and common sense) show that it's the GMA 4500MHD!

 

Great find mavci.

That press release seems to be for newly released topseller models 6474R8U and 6474R9U which have a "high nit" display. They don't appear available for sale anywhere yet nor has a February version of tabook been published yet.

Anyway, the high-nit option is currently available for custom made systems through certain (non-consumer) channels. I imagine it will appear on the regular consumer web portal soon - I'd guess within the next week or two.

The question is how bright is the display - and do you need that much brightness? Higher brightness does not necessarily does not mean a better display and in fact can often mean worse picture quality for photo and video purposes. For example, after calibrating my Lenovo L220x display the brightness is 80/100 to attain the best image quality. High nits displays are generally only useful if you use the display in high direct sunlight. If you are in a controlled lighting environment then you won't need the high brightness and you are better off with a cheaper, less bright (but high-resolution) panel on the T400.
