D620 poor screen clarity

As requested by the moderators, a new thread for the continued discussion of the Latitude D620 screen issues has been created.
It and can be found at:
http://www.dellcommunity.com/supportforums/board/message?board.id=insp_video&message.id=156588&view=by_date_ascending&page=1
or

=======================================================================================================
Great news from the moderator on this issue (see below). If anyone has one of the revised screens, please let us
know how it performs and which issues have been resolved.

Latitude D620 Customer Screen Rating Table

=======================================================================================================
Just received my D620 and I'm very disappointed with the screen clarity! The screen has a silvery, matte appearance that looks out of focus, even at native resolution (WXGA+ 1440x900). I've been using a D600 for 18 months and it doesn't suffer from the same fuzzy, washed out appearance. I'll be returning the D620 as soon as I can, even if it costs me money! :(
=======================================================================================================

Update - Sadly, I no longer have my D620 as I couldn't live with the poor screen quality delivered by Dell.
Below is a summary of this thread. I've place it here on Page 1 for easy reference. Hopfully this will help others make an informed choice when purchasing one of these units.
The most common complaints about the screen are that it's grainy, has a silvery appearance, has narrow vertical viewing angles, has light leakage and is not as bright as previous models. A picture comparision of a D600 and D620 is provided further down this page.

The following post best represents where we are at:
will0861 pg79 - "Well I spoke to Jackie again today in the executive resolution center. She told me that the engineers are aware of the issue, and they are working on a fix.......for "the next round of computers to come out." So basically the D630 may have a screen that is actually usable. Of course I have no way to verify this, but having worked in a large corporate enviorment like Dell, I am pretty confident in saying that as long as Dell doesn't notice any slowdown in sales, they will never use quality screens. And since Dell keeps their computers around for 18 months, it won't be anytime soon.
So, I have the return lables coming, and this is going back to Dell. I am actually dissapointed. The D620 is a great balance of power, and portability, but they ruined it with this inferior display.
This is the last time I tell anyone to buy a Dell laptop. Dell, I know you are a goliath, but your slipping sales, and your second place standing behind HP should tell you something. You had better improve your quality, or you will be third, behind some other company that knows how to use a clear, bright, and legible display in their laptops.

Technical updates from the moderators (in this thread):
DELL-Rollie
pg 4: "While I am not an engineer, I am in contact with Dell’s LCD engineering team in response to your concerns in this thread.  Two of our senior engineers have spent the past two weeks focusing only on this issue.  They have been working closely with our LCD suppliers to test a variety of samples.  While they have not completed this testing, they continue to look at potential causes.  I am keeping close tabs on their progress and will post an update when I have more information."

DELL-Jimmy P
pg 13: "Sorry for the delay, but I did not want to respond until I had some additional information. Now, this might be a bit complicated, so please bear with me.
Our Engineers have continued looking at the D620 LCD panels. They have called customers to better understand what exactly is being seen, captured customers’ systems, obtained samples from suppliers and held focus groups to review potential changes.
One point I’d like to clarify is that the D620 LCD panels meet the same standards of brightness, viewing angle and antiglare particles (haze) as the D610 LCD panels, just as they were designed to. The haze, used on both the D610 and D620 LCDs, is made up of these antiglare particles that help diffuse the light and reduce glare. Dell did not change this haze level or brightness level on the D620 LCDs from the D610 LCDs. Please understand that no one is saying that you do not see a difference. I bring this up in the hope that you will understand why it has been difficult for us to figure out why there is a difference.
The one key difference between the D610 and D620 LCD Panels is that the D620 uses a wide screen LCD. The wider screen LCD has smaller and more numerous pixels than the D610 LCD. This appears to be causing a more pronounced narrow viewing angle and hazier appearance for some users - which may cause a dimmer and grainier look as you have reported. We are still working to better understand this issue and will keep you updated as more information becomes available."

DELL-Jimmy P
pg 58: "The D620 Development Team continues to work on LCD design enhancements to address the LCD complaints highlighted here.  Usability and Customer Studies have been conducted and will continue to be conducted as we continue to validate proposed enhancements.  Given that we still do not have 100% of the enhancements finalized & validated, we can not commit on a roll-out date as of yet.  The enhancements would be LCD design changes - changes which take time to engineer and completely cut-in.  Therefore there is no adjustment that can be made to change the viewing on your current panel.  We will do what we can to keep all of you posted.  We understand your frustrations and are doing all that we can to deliver the level of panel performance you rightfully expect, and want you to expect, from your Dell Latitude Notebook.  We thank you for your patience as we continue to work through and validate these enhancements to optimize viewing on the D620 LCD."

DELL-Jimmy P re-posted the original technical update on Pg 36.

alesis
pg 36: "...We have many D600 and D610's with 1400x1050 screens and none of them exhibit the problems of  the D620. I fail to see how the D620 at 1440x900 with a wider screen and slightly reduced height, would have numerous more pixels..."
RGMBRAZIL
pg 37: "...the main difference in the D620 LCD Screen is the backlight that has the source of light in the bottom of the screen.  All previous models from Dell mentioned here, were not wide screen models, and the source of light came from booth sides of the screen, according to Dell supervisor explanation..."
nVladik78
pg 37: "Stopped by a Dell kiosk at the mall today to take a look at the e1405. The screen looks unbelievably good compared to d620 screens we have here...E1405 has the same dell part number screen as the d620, only different coating..."
TerjeM
pg 39: "Jimmy, there has been 1400x1040 screens available for the Lattitude 600 machines for many years now. I believe the C610 was the first model in this class that had such a screen... So, the math is: 1400x1050 = 1.470.000 pixels on the D610     1440x900 = 1.296.000 pixels on the D620"

=======================================================================================================

You would expect a high proportion of responses here to be negative as people that are happy with their screens wouldn't even come looking for this site. I'd like to encourage people that are happy with their screens to also respond so that we can see if there's a pattern of good and bad brands/models. The more responses we receive, the more we can see how big the problem is. If the list gets too long I'll aggregate the results by removing member names and provide a count of people with a certain screen types and responses.


Thnks alesis.

Welcome to the Forum,

Screen quality is top on my list for a portable system.

Try Screen Properties, Settings, Advanced and set dpi to a normal 96dpi
from the 120DPI that Dell often ships them with (supposed to make fonts bigger) ReBoot after the change and see if it looks better.

Sorry but I don't know any details of D620 (or D600) screens, you mention "backlight deffuser" and I know nothing of that except that it would likely need replaced if that were the problem.

One thing for sure, would be that it should be better than your D600. due to improved Video Software and Video Systems, was your D600 SXGA or XGA resolution?

On my older D800. there are many other settings (same "...settings, Advanced, on the Video System tab, Color Settings) and in addition to the Gamma and other sliders, it came with stored profiles to try and you could also download other profiles to store in that folder. Some are designed to look better for 'Movies' others for 'Games' etc..

Remember that Dell gives you 21 days from "SHIP Date" to return for cause and you will likely get more in the way of support during this short time period.

Hardware, software or settings, you have a problem that requires swift action. My nine year old LM still shows a beautiful screen and this D800 blew away the year old Sony VAIO (GRS700 15" XGA) that it replaced, both on brightness as well as clarity.

Checked this setting and it was already set to 96 dpi. The clarity of the font is fine.

The problem is the matting effect of the LCD backlight diffuser.

It's very obvious if you do a side-by-side comparison with a D600. The D620 has a silvery, 'out of focus' appearance, compared to the D600.

My D600 has a SXGA+ screen (1400x1050), so it is comparable.

Perhaps the best way to describe the problem is that the D620 screen looks grainy, particlarly where a white background is present. I've spoken to Dell Support and they are prepared to replace the screen, but I'm not sure if this will fix the problem.

Is anyone else experiancing this problem?

Thought I'd post some pictures to demonstrate the difference. The grainy appearance on the D620 is obvious. If any DELL engineers read  this thread, I'd appreaciate some advice on why there is such a difference. Has there been a change in screen technology? Is this something that will be corrected in the future?

Do you have the Nvidia Quadro graphics card in your 620? I've read elsewhere that getting the dedicated graphics really improves the screen appearance........

Also, what brand screen do you have? Samsung, AUO, LG???

This unit was supplied with the integrated Base Intel(R) Graphics Media Accelerator 950,
Integrated Intel 945GM Chipset - For UMA.

I don't believe this is a graphics card issue, it's a physical property of the screen that's at fault. Most likely the LCD backlight diffuser. The grainy pattern stays completely static when you move a window or image around the screen, indicating the backdrop material is at fault.
 
Can you advise how to determine the screen brand/type.

To see who made your screen, go to Control Panel, System, Hardware Tab, Device Manager. When you get to Device Manager, look for the Monitor or Display option. The make of your display should be listed there.........try looking for a details tab or something if you don't see it at first. Some examples are LG, AUO, SEC (Samsung) usually followed by some numbers.

I couldn't find any usefull information in the control panel.

Looked up my System Info on the DELL site using my service tag number, and found:
 
Parts#   Part Description
HC948   LCD,14.1WXGA+,VESA,LPL
 
 
Also, downloaded and ran Astra32. It reports:
 
Monitor Vendor:      LG Philips
Monitor Panel:        LP154W01 Internal Panel
Manufacture Date: January 2005
Minotor ID:              LPL0000
EDID Version:        1.3
Gamma Factor:      3.550
 
Looks like theres some evidence of this type of problem with WUXGA screens in the Inspiron range.
 
 
 
The bad screens in these threads also happen to be LG Philips screens!
 
It'd be good to know if other D620's have been supplied with brands other than Philips. If anyone has the DELL part number for a 14.1" WXGA+ Samsung screen that would be useful.

Interesting.....I've read elsewhere that for the most part people are very happy with the Samsung screens on the D620, but I don't know about LG.

My D620 arrives today and i'm anxious to see the display.........hopefully I get the Samsung and not the LG!

Alesis - I also have experienced what you are seeing. I am part of an engineering team and to a person everyone on my team has indicated why is my screen "fuzzy". I sit across from an IBM laptop user w/ an onboard Intel 915GM graphics chip (mine is the 945GM) and he is making fun of my screen and it's "not so clear" look. We just received this laptop for review for our company. Here is something interesting that we discovered while trying to figure out what was up. If you look in the BIOS there is a Video setting to 'Enable or Disable' LCD Panel Expansion. This is Enabled by Default on my system so I tried turning it off. Lo and behold the image becomes smaller on my screen but sharp as heck. My excitement was short lived though as when Windows boots up and after log-in the screen flashes and reverts back to its' fuzzy self. The BIOS resets itself to enabled (?). Hopefully this clues someone in on the DELL engineering side. And thanks to your suggestion of the Astra32 software I confirmed mine is also an LG Phillips display. Hope this helps.

I got my D620 today too and alas I have the same LG screen. I pumped the brightness up all the way and played with the Nvidia settings on my graphics card and managed to get it looking pretty decent. I do see what you're talking about though with the "grainy" look, especially on white backgrounds. It doesn't really bother me that much right now, but if it does, I'll just have Dell replace my monitor eventually.

efaulkner - Glad to hear you were able to find some settings that make your screen usable.
 
I ask the Dell customer service representative if they could replace my screen with a brand other than LG Philips. They advised me that it would depend entirely on local stock. To my great surprise, the service technician arrived today with a Samsung replacement screen!
 
I thought my luck had changed, but unfortunately not. :(
 
The Samsung screen suffers from the same sparkle problem, although slightly less than the LG Philips.
 
My options are limited now. I'll be speaking to Dell about returning the unit. I don't do this lightly as it will cost me about 7% of the purchase price.

The Samsung details (taken from the spare parts box) are:
Part No.        Part Desc
JC269           LCD,14.1 WXGA+, VESA, SMSNG
 
Astra32 reports (or miss-reports) the screen as:
Monitor Vendor:     Seiko Epson
Monitor Panel:      Unknown (SEC 4457)
Manufacture Date:   January 2006
Monitor ID:         SEC4457

Sorry to hear the Samsung wasn't any better.........I guess I won't waste time trying to switch displays. I think I can get used to this screen. Good luck finding a laptop that satisfies you!

By the looks of those photos the difference is that you have ClearType enabled in one but not the other.

Go to Control Panel > Display > Appearance > Effects and select ClearType.  Beware that there are two kinds of screens: RGB and BGR. (You can't change that setting here.) If it looks fuzzy with colorful edges to the fonts you need to tune the settings.

To tune your settings, use Microsofts online tuner: http://www.microsoft.com/typography/cleartype/tuner/Step1.aspx

There is also a 3rd party utility called ClearTweak, and I believe Microsoft has a "PowerToys" download that can do it too.

Good luck!
