Re: Upgrading T520 screen from 1366 x 768 to 1920 x 1080

I also ordered one from laptopscreen.com , v.4 one. Make sure you talk to a representative and ask that the particular panel you want (whichever version you prefer) is in stock. A lot of vendors, ebay sellers and third party retailers such as laptopscreen.com, carry compatible screens that may lack in quality. Unless you're fine with that, do ask for EXACT part always.

Re: Upgrading T520 screen from 1366 x 768 to 1920 x 1080

Just to add to this with my experience on the T450.   Came with the standard screen and I purchased the HD+ screen, however does not work with the standard cable.

 

Seems the T450 is fitted with the single channel cable and the HD+ needs dual channel.

 

Having a nightmare finding the cable to buy...... If anyone knows any part numbers, it would be helpful.

 

Interestingly enough, on a Lenovo Parts PDF, they only list 2 cables.  1 for Non-Touch and the other for Touch.

Re: Upgrading T520 screen from 1366 x 768 to 1920 x 1080

 Regarding the LCD model: The AUO B156HW01 V4 (same FHD display shipped with the T5x0 and W5x0) is one of the best 15.6" 1920x1080 displays available, but the AUO B156HW01 V5 is one of the worst (ironically). The V4 is matte, has excellent contrast, and has a high color gamut (95% NTSC). The V5 is glossy (not necessarily a bad thing, but is a difference between the two), has very poor contrast, and has a standard gamut (60% NTSC).

 

------

 

As for buying the AUO B156HW01 V4: The best place that I have found to order this exact part is here: http://www.laptopscreen.com/English/screen-part-number/B156HW01%20V.4/

Hey, edit1754.

 

I'm doing a little research because I have a T520 on which I want to upgrade the 1366x768 screen.

 

I searched laptopscreen.com and found that both B156HW01 V.4 and B156HW01 V.5 come in matte as well as glossy.

Are you sure about your best/worst assessement as it relates to gloss/matte and model number?

Was the AUO B156HW01 V4 the only screen shipped in new T5x0 laptops or did Lenovo use other vendors?

 

Searching eBay and other sites I have found devices from several manufacturers matching Lenovo's FRU, 04W1544 (LCD module, 15.6-inch FHD LED-backlight).

 

Also, is finding an exact match on "AUO B156HW01 V.4" enough to ensure that I get the 95% NTSC unit or are there other details I need to specify?

For instance, laptopscreen.com has three models:

B156HW01 V.4

B156HW01 V.4 HW0A

B156HW01 V.4 HW1A

Are all these the same? Is one preferable over the others?

If I remember correctly, the T530/W530 had also other panels as well.

I've done few T5x0/W5x0 mods with several B156HW01 V.4 and never seen different submodels, so I can't say which one is better, the "plain" v4 was considered the best panel at that time.

 

FWIW, I have also used B156HW01 V.5 (not so good as V4) and B156HW01 V.7 (same as V4 but glossy instead of matte). As well as a LP156WF1-TLB1  (very nice, but still inferior to the V4). They all worked perfectly and with no issues.

 

All these panels are plug & play.

Have you used screens from other brands? Any that are as good as the B156HW01 V.4?

Yes, a LTN156HT01-101, which in my opinion is even inferior to the LP156WF1-TLB1.

 

So the AUOs V4 or V7 remain your best choice...
