    hi folks,

    has anyone tried swapping the 720p display that comes with this model for a 1080p display?

    there's a good tutorial for swapping the 720p screen here:

    **TUTORIAL** LCD Replacement/Repair for Lenovo Thinkpad Edge E520 - YouTube

    the maker of the tutorial said he'd tried a 1080p but it didn't work. on the dell forum, there's this thread:

    http://forum.notebookreview.com/dell-xps-studio-xps/554402-dell-xps-l501x-lcd-display-swap.html

    ...which shows a different fullHD capable cable was needed. i'm guessing this is the same deal with the e520. on page 32 of that thread is a picture of the new cable. anyone know if that cable looks like it would work on the e520? or have any input on this idea? the screen i would like to put in is the matte screen talked about on the earlier thread. its basically the dell xps 1080p screen but matte...


    gary.

    I think HD+ (1600x900) is better for a 15.6" display then a FullHD (1920x1080).

    FullHD there a some very good displays from AUO.
    • AUO B156HW1 V.4: Full-HD, LED, 1.920 x 1.080 Pixel, Glossy, 500:1, 95% NTSC 195 US-Dollar
    • AUO B156HW1 V.7: Full-HD, LED, 1.920 x 1.080 Pixel, Matte, 500:1, 95% NTSC 195 US-Dollar

    Maybe somebody know if there are some good HD+ displays with good color and contrast 500:1 (or better).

    Perhaps it is possible to take a display used in T520?

    Maybe someone can get hands on a LG LTN156KT02401 (FRU 93P5681), HD+ display, that Lenovo puts in L520 and T520. Test see above.

    If this one works in E520, this will be very nice!

    You can swap to a HD+ (1600x900) or FullHD (1920x1080) display like in Lenovo L520/T520 or W520. Both of them are very good compared to lame HD display in Lenovo E520.

    Review FullHD display in Lenovo W520:
    Review Lenovo ThinkPad W520 Notebook - Notebookcheck.net Reviews

    But you may need an other Display-Ribbon-Cable (FullHD capable) that is used in L520/T520/W520. You can order this cable directly at Lenovo support. I will swap my dispay in a couple of weeks.

    FRU's for HD+ / FullHD cable are 45M2859 Teflon and 45M2860 Coaxial.
    FRU for HD Cable is 45M2857 Teflon and 45M2858 Coaxial.


    You can order cable here:
    http://support.lenovo.com/en_US/detail.page?LegacyDocID=MIGR-73348

    Here a thread about the cable:

    Does anyone know if there is an IPS screen yet that fits the E520? I dont care about the resolution personally, so much as better image quality than the standard TN panel.

    Sorry to OP if this post is not wanted, if so I shall remove it.

    Thanks for reply!!!
    You replace of exactly model and work of 100%? and what screen recommend me? I think with 1920x1080 screen will be very small or wrong.

    And the cable of E520 FRU is 04W1850 or this is not problem and can put HD+ cables.

    No, there is no compatible IPS screen. But look at this AUO Display, it is very good (http://www.notebookcheck.net/Review-Lenovo-ThinkPad-W520-Notebook.53220.0.html). So only if you allways want to look at your screen from a 90° angle, then you really need a IPS Display. I have one Lenovo X220 with IPS Display here, viewing angle are great, but colors not. Good TN+ displays like AUO have much better colors and contrast.

    I've read in a german board, that cable is same in all 520 (e520, l520, w520, t520, sl520). You even can solder yourself the missing links/wires in HD cable, if you dont want to buy the HD+ cable. Look here:
    HD+ Matrix on SL510 - Lenovo Community

    Recomended displays are:

    Yes, FullHD on 15,6" will have very small fonts. On other side you have a lot of space for documents (open office, cad, photoshop). HD+ is better i think for 15,6" Display. But FullHD AUO is very good, so if fonts are small for somebody, you can increase them in Windows7 Settings to 125%.

    Thanks for the information!

    Ive just received the E520 with 1366x768 matte, and the screen is indeed rather below average.

    If the 1600x900 matte is better quality as well as higher res, I will get it.

    Laptopscreen.com does not list any 1600x900's for the T520, only the W520 and T510

    IBM-Lenovo THINKPAD T510 replacement Laptop LCD Screen from $59.99 Brand-new screens (never used).

    IBM-Lenovo THINKPAD W520 replacement Laptop LCD Screen from $59.99 Brand-new screens (never used).

    I will email him and ask which panels the 1600x900 above use.

    Edit:

    Received an immediate reply from laptopscreen.com so I may try the 1600 x 900.

    I also recently bought an EC520 for my wife, but noticed the display is close to unacceptable. While it has the same ppi as the 1280x800 panel on my 6-year old Dell Inspiron6400, the image quality is much worse.

    So I spent the last week trying to explore the possiblity of upgrading the panal, ideally to something like 1600x900. And I would like to share my limited finding here and see if it can contribute to the first success:

    - The 1366x768 (so-called HD) panel on my E520 is an "AUO B156XW02 V3"; it requires a 40-pin 'LVDS single-channel 6-bit' cable. Unfortunately (according to another forum) anything above 1440x900 must be connected using a dual-channel cable as more pixels need to be transmitted at a time. This simply means upgrading the E520 panel is not a plug&play job. Some people have tried to plug a HD+ panel into E520 and only found that half the pixels were lit (because only half of the channels are connected). SO just a kind warning here: DO NOT buy the HD+ panel before you know how to get the right signal out of the master-board;

    - The potentially usable 1600x900 (so-called HD+) panels I've found are "LP156WD1-TLB2" from LG and "B156RW01 V1" from AUO. According to their specs, they both require 40-pin 'LVDS dual-channel 6-bit' cables, and apart from the 8-pins that are not used in the single-channel connector, all other pins seem to have the same assignment (which is a good sign).

    So now there are two remaining questions:

    1) Does the E520 master-board actually supply 1600x900 signal to the LVDS cable? If not, there is no way to upgrade, but I may still consider replacing the lame panel with a better HD one;

    2) The LDVS cable in E520 (FRU 04W1850) also carries signal for the camera/mic; presumably the cable at the masterboard-end should be 44-pin, then split into 40 to the LCD panel, and the other four to the camera/mic. 8 of the 40 pins should be 'not connected'. For a HD+ panel, we will need find a cable with all 44 pins connected. As E520 doesn't have a standard option of HD+, I don't think Lenovo actually make such cables. So is DIY the only way to get hold of such a cable?

    Can anyone find the answers to these questions?
