Dell Latitude E5570

Having the wrong display resolution would make things look blurry, but Windows usually gets that right.

Therefore I wonder if the anti-glare coating is the problem. Having no anti-glare coating gives the clearest displays but these are then vulnerable to reflection problems.

On some displays this can cause the "screen door" effect which is like looking through a fine wire mesh door and reduces the clarity and contrast. On the 14" panels which Dell uses I found that the LG display was slightly better than the AUO in this respect so I was surprised to find that the 15.6" AUO panel was better than the 14". The Sharp panel in my Precision 5510 has better contrast than my E5570's AUO panel which I attribute to having less anti-glare coating. You can see this in the photo of these two notebooks side-by-side in my 5510 review where the 5510 has more glare. I haven't noticed this to be a problem in everyday usage.

thanks john, i'm not sure if there's a screen door effect. i checked for pwm and there is pwm. maybe the present of blue light contributes to the eye fatigue? i read that dell is infamous with having the blue light problem in their wled screens.
i tried all kind of local solutions (increasing brightness with the fn keys and decreasing/increasing the brightness + reducing the contrast in intel graphic. all to know good.
meanwhile i couldn't figure any other solution. any ideas?
this is the second time that i'll have to send my e5570 back.
i bought the e5570 because i'm a fan of the keyboard and i wanted a nice screen. any idea if dell implemented this keyboard in another model?

 

In my experience (guided by my Datacolor Spyder calibrator) most notebook displays have a blue bias. You could search thorugh the reviews at notebookcheck to see if another notebook has same AUO display in which case you can download and use the .icc display calibration file.

The Precision 3510 is basically the same as the E5570 and has the same keyboard. However, I suspect it also uses the same display panels - you will have to search for clues.

thanks! unfortunately the 3510 isn't an option.

i did download the "icc profile 6500k" that is in notebookcheck.pl review of the dell 3510, that seems to have the same LG panel (and the same dell p/n part) as the e5570. although i am not really sure what this ICC file stands for (not sure what it is exactly??), but it sure didn't made any difference what so ever to the viewing experience.
anyone that is interested can download it from this link: http://www.notebookcheck.pl/Recenzja-Dell-Precision-3510.168276.0.html (CTRL+F - find the word "ICC" and press on it).

also, i can confirm that the LG panel uses pwm (i did the ufo test and the pencil test). maybe this is the reason to my eye fatigue.

is there any way to know in advance which configuration of the dell e5570 uses the AUO/Samsung panel? or is it just more likely to aim for the higher end models?

 

1. Make sure that the computer is using the .icc profile. There are some instructions here. You will notice a change in the colour balance - probably less blue and the white less dazzling.

2. As far as Dell is concerned, the AUO / Samsung / LG panels are interchangeable and not assigned to particular versions of the notebook. Indeed, their inventory system may not specifically recognise the manufacturer. My E5570 parts list (put the service tag into the Dell support site) says "F7HH2 LIQUID CRYSTAL DISPLAY, 15.6FHD, AG, EDP1.3, LEGEND" but is actually an AUO panel. The notebookcheck.pl review of the E5570 has the same part number for the LG panel. (Similarly, the parts list for my 5510 said Samsung PM951 SSD but it was a Toshiba SSD with equivalent performance.) This interchangeability is why Dell support can't promise that a replaement part is from a different manufacturer.

However, we need to be certain that the panel you have received is not defective in some way. The photos in the notebookcheck.pl review make the display look good and there are no adverse comments by the reviewer. I found the 14" LG panel in my E7450 to be easier on the eyes than the AUO panel of the E7440. Again, both parts are equivalent in Dell's system. Don't normally use the display at full bridghtness. You should find around 70% to 80% brightness is plenty for indoor use.

Quick question please, I am getting a E5570 with a 500GB 2.5" HDD and 4cell (smaller) battery. Can I add a M.2 SSD in addition to the 2.5" HDD? I know I will have to order some small bracket to secure the M.2 SSD.

In the E5470 I understand that the M.2 SSD and 2.5" HDD would occupy the same physical space; hence you cannot have both installed at the same time. However, in the E5570 with its larger physical footprint can I install both M.2 SSD and 2.5" HDD at the same time (with the smaller 4cell battery of course)? Thank you.

 

2.5" HDD shares space with the M.2/PCIe 2280 ssd slot (and battery). Need a bracket if you want to use m.2. must choose between m.2 and 2.5", cant' do both. If you choose larger battery (6-cell), can't use 2.5", can still use m.2/PCIe 2280

in addition to the above, there is a spare WWAN slot which only accepts the shorter m.2 2242 SATA cards (must be the 2242 length, not 2280 length. probably doesnt support PCIe but no one has tried a 2242 PCIe card). You only need an extra screw to secure the m.2 2242 card

on the E5470, it's the same thing (2.5" sharing space with m.2/PCIe 2280, has additional spare WWAN slot for m.2 2242 SATA). E5470 doesn't have any extended battery options, only 62WHr 4-cell (or 47Whr 3-cell)
on the E5570, 47Whr 4-cell allows you to use 2.5". if you choose to upgrade to 87Whr 6-cell, you can't use 2.5", only m.2/PCIe 2280)

 

Ah ok, I was aware if the space limitations in the E5470 but was hoping that the 15.6" E5570 would have enough extra space to accommodate both a M.2 SSD and 2.5" drive...guess not! Thanks for your confirmation, I may have to return this E5570 (although I got a pretty good deal for it via the Outlet) after I receive it.

 

The photo in the E5570 owners manual shows that a 2.5" drive will block the M.2 bay. Had Dell provided a slightly smaller battery then the 2.5" bay could have been moved across and dual drive would be an option. I'm a little surprised that they didn't do that (those who want long battery life get the big battery) as an SSD boot drive with HDD for bulk storage is a cost-effective balance between performance and capacity.

Thank you John. Yes, I saw the photo but to me (maybe wishful thinking) it looked like maybe you can fit both M.2 and 2.5" SSDs. Welp I just got the laptop and sure enough, you can only have one or the other (2.5" drive or M2. 2280 SSD). Yes, you can buy the 2242 M.2 SSD and put in in the WWAN slot...but I already own a few M.2 2280 SSDs and want to re-use them.

I feel like each subsequent generation of Latitudes, which still nice in their own right, are downgrades in functionality from the previous generation. I have both a E5470 and E5570 now that I just bought and will have to decide which one to keep. Functionality-wise, the 14" and 15" 5000-series Latitudes are basically the same this generation! 1-spindle out-of-the-box (the 2242 M.2 SSD in the WWAN slot is not really advertised as officially supported I don't think) with same CPU and GPU options...just screen size difference and numpad in the 15" (off-set keyboard as a result). Even the batteries appear to be interchangable. I got the 3cell for the E5470 and 4cell for the E5570, and was able to swap them (the battery connector cable is specific to the E5470 and E5570 though, since they are different lengths. However they are removable both from the motherboard and battery ends).

Anyone have a reliable source in the US to purchase the M.2 SSD bracket, plastic shroud cover, and M2x3 screws? Both my laptops came with 2.5" drives so I'll need these parts to install a 2280 M.2 drive...major PITA I say.
