Dell :: WUXGA Screens In M4400 And M6400
Nov 3, 2008
I am a Thinkpad user but extremely interested in the Dell M4400 and M6400 because of their seemingly better screens. I would love to get details on these screen, most importantly are the IPS ("FlexView")?
Questions:
1. What does "Edge To Edge" mean?
2. What does "RGB" mean?
3. Are any of these screens IPS "FlexView"?
M6400:
17" WUXGA UltraSharp Display (1920x1200) Resolution
17" WUXGA RGB LED Back-Lit Display (1920x1200) Resolution
17" WUXGA RGB LED Edge To Edge Back-Lit Display (1920x1200) Resolution
M4400:
15.4" WUXGA TrueLife RGB LED display (1920x1200) featuring 100% Adobe® Color Gamut
15.4" WUXGA AG day light viewing (1920x1200)

The CCFL WUXGA screen belongs to a precision M90 and is almost 3 years old. Keep that in mind for this review.
The RGBLED is way brighter than the CCFL; at nightime, I would only use the minimum brightness setting.........................

There is now an RGB LED option available for the M4400 for $299. I'd love to hear how this screen performs in real life.

The hardware id is SEC5443....so it's the Samsung panel. Can anyone tell me the hardware id of the LG 2CCFL WUXGA 15,4" so i can ask Dell to replace it for that?
It's actually weird that of the two possibilities for the the panels on each type
WXGA+ WLED ...samsung has the better one
WUXGA 2CCFL....LG has the better one?
is this right? If not i'm going to try to have it replaced with the RGB LED when it's available

I'm thinking about buying a M4400 with WUXGA 2CCFL screen.
I'm a web developer, so I need "space" on the screen for running programs as Eclipse, etc... However I'm a bit worried for if the fonts (reading text, typing code...) are very small.
I read that the Vista DPI scaling engine is really good and can solve this issue.
Could anyone attach some screen captures with 96 dpi (default) and 120 dpi, using Vista DPI scaling?

discussion on the RGB WUXGA screen but nothing definitive. This display is the main reason I am interested in the M4400 over the W500. Can anyone comment on the quality of this display? Is it bright, good contrast, ect? Also, the Dell online site says it is a "TRUELIFE" which I believe means it is a glossy screen. Do they offer a non glossy screen over the phone?
My other questions are a bit more minor:
Does this laptop use the Centrino 2 G45 chipset? I ask because the Dell's don't have DDR3 memory which I thought was a requirement for Centrino 2 chipsets?
What is the size of the HDD slot? The Dell configurator allows for 2 HDD's. Does this mean there are 2 HDD slots or is it using the DVD slot for the 2nd HDD?
Does this laptop do well with SDD's? Specifically Intel's speedy SSD's? I know the Lenovo's cannot use the full speed of the SSD because Lenovo slowed down the SATA port for battery life.
Is the keyboard and trackpoint good quality? I know Dell consumer laptops have horrible keyboards. Does this compare well to Lenovo keyboards?
How is the overall build quality? I know it is a magnesium structure. I am mostly concerned with how stiff the screen is? I hate screens that wobble around.
Is there anything else I should know about this laptop?
This is what I am looking at:
Core 2 Duo P8600 (2.4Ghz / 1066Mhz FSB / 3MB L2)
Windows Vista Basic
1GB DDR2-800 (2x1GB)
Internal Backlit Keyboard
Nvidia QuadroFX 770M 512MB
80GB 5400RPM HDD
15.4" UltraSharp WUXGA (1920x1200) RGB-LED TRUELIFE Display
Dell Wireless 370 Bluetooth Module
Intel WiFi Link 5300 802.11a/g/n Draft Mini Card
6 Cell Battery
3 Year Basic Limited Warranty and 3 Year NBD On-Site Service
$1811
I will add my own memory and hard drive and upgrade the OS to Vista Ultimate using my schools free upgrade.

it is only 51mb.
Specviewperf is probably a better openGL benchmark,particularly for the common openGL software used,but is a rather unreasonable download size compared to this,which does a short openGL test as well as cpu rendering tests.
So if some owners of any of the Precisions can post a score here,it will probably be helpful to prospective owners as to what sort of comparative performance between models and specs there is.
here is mine,specs ...

I bought two laptops from Dell Outlet M4400 and M6400. Really need help deciding which one I should keep (and add to my signature) and which one to send back. I am sure this community can help me make an informed decision. Thanks.
My usage:
-Development - VS 2008, MS SQL and tools.
-Graphics - Limited Photoshop (Beginner to Mid level)
-Virtual Machines - 1 to 2 at any given time
-Always ON configuration
-NO Gaming - sorry I suck at games!
-Occasional Travel
M4400: $1500
QX9300 - 2GB - 80GB 72K RPM - RGB LED LCD - NVidia 1700
My plan is to swap the 80 GB with my tablet PC's 120 GB and install 320 GB in modular bay also get 4 GB RAM bringing total cost to about $1650
Pros: Manageable size, RGB LED
Cons: Additional cost for RAM and modular bay HDD, Not sure about TrueLife Glossyness yet!
M6400: $1700
QX9300 - 4GB - 120 GB SSD + 250 GB 72K - WXGA LCD - Nvidia 2700
Pros: Pretty much everything
Cons: Low res LCD and BIG+Heavy even for occasional travel or meetings.
I could find cheaper configurations but I picked the one's with QX9300. There are some available in both machines that are T9900 and are ~$300 cheaper.
Questions:
1. Am I making the right decision by getting QX9300 given my somewhat non power usage? Is heat an issue in either? I do want to future proof at least for 2 years.
2. If I go for lower CPU should I go for x9100 or T9900 or Q9000/9100, they do show up occasionally on the outlet site.
3. I really find the second hard drive option useful. Does the slightly higher mobility of m4400 justify additional cost to buy and install the mod bay HDD?
4. Are the prices reasonable for the configurations above? I can find a m4400 with T9900/4GB/250GB/WXGA for ~$1150 and a M6400 with T9900/4GB/NO SSD for ~$1200

The M4400 supports dual-channel DDR2-800 memory.
The M6400 supports dual-channel DDR3-1066 memory.
Both systems have a FSB that operates at 1066 MHz.
I'm trying to understand if the different memory technologies ultimately make a difference for computational (i.e. math on large data sets) performance in these particular machines.
Consider an M4400 and M6400 with identical CPUs and amounts of DDR-2 and DDR-3 memory, respectively. And suppose that all relevant memory latencies are identical. For the sake of this question, I don't care about power consumption and heat (which is obviously a benefit of DDR3).
Question:
Since both machines support dual-channel memory operation, the maximum effective bandwidth of the memory bus is doubled. So the dual-channel DDR2-800 can achieve 12.8 GB/sec transfer rate, while the dual-channel DDR3-1066 can achieve 17 GB/sec transfer rate. In either case, these rates are higher than the 8.5 GB/sec rate that the FSB can achieve, so it seems that performance in both machines is limited by the speed of the FSB (1066 MHz). Is that correct?
For more info on matched FSB and memory ratings under Core 2, see:

Yup me again, in my hunt to determine if M6400 is right for me as it costs just about as much as a used car, I want to make sure its a good investment before I buy it.
What is the main difference with the M6400 and the M6400 Covet?
I configured both with the same specs and the Covet is about $900 more in price?
Does orange paint really cost that much?

Dell only offer the 1080p (WUXGA+) screen(s) in the country I am in. I am planning to get the 15.6'' one. the high
I think I will have to find a place where I can have a look on a notebook with that screen, and see if I can handle it. Right now I am very sceptical. I just can't believe that Dell do not offer the 720p screen when I am finally ready to take the plunge.
Is there anyone here that can actually use WUXGA+ on 15.6-16'' without having to resort to changing DPI, font size or zooming?

I met a guy who had a e1705 with the 1440 by 900 LCD with Xbrite, and I must say that I felt it was a great looking LCD. As a gamer I can't help but feel that my games would perform better along with my 7950 GTX with a smaller native resolution. And it wouldn't bother me because it still has the Gloss and Xbrite like features.
I was wondering if someone out there knew what type of gains and losses I'm looking at overall. I'm seriously considering changing out my LCD on my M1710.
But.... My blu Ray's wont' work will they? Well they won't play at 1080 anymore right?

Looking at the Studio 15. I've had 15" Dells in the past and always got 1680x1050. Thought it was a great resolution. Now they have 1920x1200 or 1440 x whatever but LED.

whether the optional WUXGA (1920x1200) display is an LCD or LED? I know the base/standard WXGA (1280x800) is an LCD and the WXGA+ (1440x900) is an LED, which explains why it's a $125 upgrade.

I moved my WUXGA 9300 screen to my new M90. It works okay and looks gorgeous, but it's 'off' position is solid white. Meaning when the screen turns 'off' it goes to solid white.
Anyone know why this is happening or what I could do?
I'm running the A08 Dell BIOS and I have a Quadro FX 1500m.

Does anyone know if this screen would be compatible with a Dell Studio 1737, even though mine just has the WXGA+ screen? Mine has been cracked and someone is selling one new on eBay for £86.99 which is a decent price

What do you use to clean your screens with? I have grubby little fingerprints ALL over mine, and it is especially annoying on black screens in movies/games and such.
I almost bought a pack of normal "LCD Cleaning Wipes" but then I noticed it had Alcohol in it and shyed away from it. Why? I'm assuming that Alcohol would hurt the sensitive gloss finish on the screen, but my assumption could be wrong (and hopefully it is, would be much simpler to use those wipes). I also tried just using a dry wash cloth and just gently rubbing the prints off, but it only smeared them, and I'm afraid I'll damage the screen if I push any harder than I already am. Using a wet wash cloth seemed to have no effect either.
So how about it? What method do YOU use, and find best, to clean your screens?

the question is pretty much in the title. I'm thinking about buying a E6500 Latitude with WUXGA 2CCFL display. The comments about the 2CCFL backlight I've read so far haven't been very positive, but I haven't owned a backlight so far and can't decide how serious the possible issues are.
I'm mainly working in a text editor on a black background or surfing the web, in particular I'm not doing any photo editing. I'll watch a DVD from time to time but I'm not used to the best display and it shouldn't be too hard to meet my demands when it comes to colors. But of course the display shouldn't suck,
displaying wrong colors or being bright at some places and dark at others. And it should be sufficiently bright for working under normal lighting conditions without having to sit right in front of a wall with curtains closed as it is the case with my current display.
The alternative would be a WSXGA display with LED light and I'd probably choose a E6400 instead of a E6500 in this case. But I could also buy it on a E6500.
I'd appreciate any suggestions helping me which display to pick.

I ordered my XPS M1530 at the beginning of this month, and I decided to add a blu-ray drive to it, so they had to cancel and place the order again.
I received my XPS m1530 this Monday 12/15/2008.
M1530, t9300, 4gb 667mhz, 8600mt 256mb, 320gb, Blu-ray Burner, 9cell, midnight blue...
One of the main reasons I chose to go with the dell was:
A. I had the option of having a very high resolution screen 1900 x 1200 (wuxga)
B. I got a good deal on a 4 year accidental damage warranty w/ the package.
--
I was so excited about getting a 1900 x 1200 screen; it would allow me to be as productive as on my desktop since I work with many windows open. I also play a little with video editing.
As soon as I received it I tested out the notebook for several hours.
The first thing I noticed was that white and light colors are shimmery / grainy. I have never seen this on any other screen that I work on.
After several hours I found myself feeling a little nauseous. In addition, my eyes felt strained.
I have never experience this in my life as I sit in front of computers 8-10 hours a day for the past 20 years (Work).
I raised the DPI of the fonts in vista to make them a normal size, so I don't feel that the size of the letters caused this feeling.
The next day, I decided to try again. This time I set the screen to 1440 x 900. I still experienced the same effect. I think the shimmery / graininess of the screen is causing this, as it causes the text to blend in with the background to a degree.
I tried using the notebook throughout the week. I tried getting used to it, and I did somewhat, but still felt uncomfortable working on it for an extended period of time (after only 2 hours).
I then called my sales rep. to see if he had heard of this problem. His only advice was that I should call customer support.
I called customer support, and got someone from the Philippines on the phone very quickly. The person was very nice, friendly, and wanted to help me. I was impressed. (They probably don’t want me to return it within 21 days).
He told me this is the nature of the wuxga screens. He was willing to send me another notebook to compare it with either a 1440x900 display or another wuxga.
I then did a bit of searching and found other people expressing dissatisfaction about the graininess (which is what I think is causing my fatigue) on the wuxga screens as well as other Samsung screens.
My question to everyone is:
Has anyone else experience this?
Do you think switching to the 1440 x 900 LED screen will resolve this issue?
Does the WUXGA 1900 x 1200 screen come in any other brands besides Samsung, eg. LG ?
I am really dreading on downgrading to 1440x900 as I love the real estate that the wuxga screen provides, but something is up with its quality.
I am trying to convince myself that I will get used to it but I really do not think this is the case..

I'm not really all that up to date on laptop hardware, especially so far as the screen and such is concerned, but I would like to put a WUXGA screen in my DV7t, is this possible? Will just any WUXGA panel work and plug in, or am I going to be stuck with an HP WSXGA+ panel? Either way, I have to upgrade this 1440 x 900 display,

I received a Latitude E6500 with a WUXGA screen with the dreaded screen brightness problems. This is the same problem discussed here:
E6500 WUXGA -
The bottom corners on mine are very dark. I had been expecting a little, and had been planning on dealing with it like I have with some laptops in the past, but it's kind of outrageous how discolored they are. Screen brightness evenness is very poor as well, with the bottom part of the screen significantly brighter.
My purchase order lists my screen as:
Module,Liquid Crystal Display 15WU+,2CCFL,Samsung Maybach/Avia
How are people getting the exact model number and part number for their displays?
At any rate, it's the bad Samsung kind of screen. A lot of threads including the one I linked to state that there is also an LG/Philips screen that is much better for the same Dell WUXGA screen component.
Has anyone managed to get Dell to change a Samsung screen for an LG/Philips? If so, how did you do so?
My chat rep tells me that they can only replace using whatever was in the order initially.
