Precision M4400 Owner's Lounge

I totally agree... I have a FlexView and it feels so stupid when a new machine can only be a major downgrade.

Notebookcheck.com (and .net in English IIRC) offers viewing angle demonstrations as videos and usually talks about color quality/ calibration aspects. Though I still don't know which screen/ notebook is an acceptable successor for my T42p.

 

The WXGA+ LED on the E6500 & the M4400 are pretty much the same screens, offered by different vendors across both models.
Aside from the higher resolution, I can't make out the difference between an M4400 with WXGA+ LED & an M4400 with RGB-LED side by side.

 

Notebookcheck.net was the only site I found that frequently gave this kind of data, which is why I said "Most of them." I raved about them here a week ago, just before I purchased my M4400 (which I just received the shipping notice for, yay!): http://forum.notebookreview.com/showthread.php?t=357650&p=4573460

I'd found Notebookcheck.net's reviews for the E6500 and E6400. However, though the E6500 review included a viewing angle demonstration, it was missing the contrast ratio data, and basically said the display didn't "approach" the quality of the old Flexview displays (they didn't review the WUXGA LCD option, though, which I would have loved to see). The E6400 WXGA+ display is quite bright, but has rather dismal contrast, and the viewing angle photo reminded me thoroughly of my crappy T61p LCD "frosty" Samsung panel. Neither review included color gamut charts, response/input lag times, or other useful data for quantitatively describing the display's actual image quality. /sadpanda

So yes, I'm a big fan of their reviews, but despite them, it's still usually impossible to find the quantitative information about particular models/displays I'd like to know about. I want a good display badly enough to take a chance on the unreviewed M4400 RGB LED display...the few user accounts I've heard of it indicate it's a pretty good option (despite no current version of Windows being capable of accurately displaying colors on a wide-gamut screen). I'm optimistic, I'll soon see for myself!

 

Regarding LCD info for WXGA+ LED screen on Latitude E6500, the notebookcheck review lists the folloowing, pretty good contrast after hardware adjusting of screen.

Maximum
303 cd/m²
Average
287.8 cd/m²
Black
0.46 cd/m²
Contrast

Thanks, I hadn't noticed it there, in the light gray text next to the picture. I'll blame my crappy Samsung LCD panel...

If this M4400 RGB LED doesn't impress me, I'll probably send it back and try out the E6500.

I forgot to mention, one thing even the Notebookcheck.net reviews usually omit is the LCD panel identification information (manufacturer, model number, etc.). Unfortunately, manufacturers (Dell and Lenovo, for sure) often use multiple LCD panel types (with different characteristics), even for the same laptop model and selected display option. Granted, this information may be of limited use, given that manufacturers don't allow customers to request specific subcomponent manufacturers or model numbers. However, maybe publicizing this info would force them to start including that info/option, or stop using multiple types? If I was buying an expensive car, I'd certainly want to know if any major components were going to be swapped out for potentially substandard components made by a different manufacturer.

 

that would damage their relationship with the suppliers, and potentially cause supply issues (if people are demanding one and refuse to buy the alternative supplier)

but its a nice idea though, could be used to their advantage if they say right we only use the market leading brand components

i was quite surprised dell uses a branded webcam in the M4400 ( i forget, its either creative or logitech

i expected it to be some generic module

 

Regarding the displays available on m4400, and especially wuxga questions, and the rgb led spec, I'd recommend You viewing the following thread: M4400 - WUXGA vs WUXGA RGB LED...

http://forum.notebookreview.com/showthread.php?t=333840

 

this might be a bit off topic, but does anyone know the screen type on the WUXGA inspiron 8600 and the UXGA inspiron 8200?

i ask because they seem to have better viewing angles than my precision m4400. are they IPS screens? the 8200 in particular has very good viewing angles, when i saw my team mate's IPS thinkpad screen i was reminded of it.

 

Thanks! Trust me, I saw it prior to making my purchase. It was a very interesting thread, though lacking some important *quantitative* information. Still, the side-by-side pictures were very useful...I'm a big fan of that kind of DIY quasi-quantitative analysis. With the help of another NBR user, I did a side-by-side photographic T61p comparison a year ago, to try to settle the Samsung vs. LG WSXGA+ panel debate.

 

yeah, me either found the WUXGA vs WUXGA RGB LED topic very useful at the time before the purchase, and even after
