Disappointed with LED LCD in E6400

I would go with the WUXGA. From what I hear, it is an excellent screen. Brightness should be comparable to the LED version due to the WUXGA using 2 CCFL lamps. It will also have much better color reproduction.

I understand the way you feel. I was so pumped when LED screens came out, but I have had a 1330 and now a 6400 with crappy LED screens. Dell needs to stick with the supplier that has better screens. (They should call Sony and try and resource some xbrite screens)

I know I can call Dell and have them send me another LED screen, but I don't have the patience to go through calling them, waiting for the part, hoping it is a better screen, then swapping it out.

 

Mine's the LPL0140 (LG) and, as I have said many times, I'm very happy with it.

I normally run at half brightness under which condition the contrast and colour reproduction look good. Higher brightness is only needed when working under very bright lighting (eg outside) in which case being able to read the display at all is a major bonus. It's also quite usable with the brightness one step above minimum which helps the battery life.

Aside from the better battery performance, I don't have to worry about the CCFL lamp gradually losing brightness.

I am sure you would have either a)sold the laptop or b)replaced it with a newer model before you would get to the panels half-life.

Seriously, I keep a laptop maybe 3 years. There is no way that I could accumulate enough hours on the lamp to notice the dimming.

I love LED technology, I just wish Dell would stick with LG and get rid of the horrid samsung pieces of crap!

 

I have had 2 E6400s since they were released. I got an exchange because my first one had some dead pixels.

Both of the screens looked fine to me but I don't do any photo editing and the only comparisons I have are some old Dell 19" flat panels, the 12.1" flat panel on my xps m1210 (looks like garbage next to the LED screen in the E6400), and my 24" samsung 245BW.

The only one that beats the E6400 LED screen is the 24" samsung. And what I mean by beats is that it is brighter and everything looks sharper but that probably has something to do with with the fact that it is a WUXGA desktop screen.

 

No, it probably has something to do with that 24" Sammy having a S-IPS or PVA panel....

I am pretty sure that, aside from the 17" WUXGA used on the XPS, these laptops use crappy TN panels.

 

That's a definite possibility. I don't know much about LCDs all I know was it was the best looking one out of all the ones I looked into buying.

 

The Samsung 245BW uses a TN panel, but its a pretty good one (I have one), and as far as I know ALL current laptops use TN panels. The only one I know of that doesn't/didn't is the flexview screen found on some thinkpads which was an IPS panel (godlike). The quality of TN panels varies wildly (at least with laptops). Go to Best Buy and take a look at a Macbook Air or a Macbook Pro if you wanna see what a good one looks like (for a laptop). Also 100% of those desktop monitors on display are TN panels, though you might see a Westinghouse LM2410 (MVA) or any Apple Cinema Display (S-IPS).

 

^ Sony AW series has a RGB backlight. Not sure what panel in uses.

But generally speaking any good desktop monitor is brighter and has higher contrast than laptops.

 

Anybody have the same problem?:
If the brightness is on the lowest step, the display is flickering?

I´ve an Samsung panel...

Edit: It´s only when the notebook runs with the battery...

 

So is it the general conclusion that the Samsung LED panels are the problem and the LG LED panels are good ?
