Y50 Replacement Displays Compendium

I didn't notice the difference between the TN and the IPS in input lag in BF4. I was able to maintain above a 2:1 K/D fairly easily, without too much of a hit compared to how I do on my desktop. I'm sure it's there, but the better quality screen definitely makes up for it. I didn't see much of a difference in the amount of ghosting either. Again, it's there, but not much more and the quality of the screen makes up for it.

 

+1 for the B156HAN01.2 ordered from lcdtech889 on ebay. Could not be happier with this upgrade. Big thanks to everyone in this thread.

 

Hi all, I recently discovered this forum after googling a bit about my newly acquired Lenovo Y50.
I want to replace the original TN panel of my Y50 and I am trying to find the difference between B156HAN01.2 and B156HAN01.1 - could anyone help me out here?
What would be the cheapest place to order from Germany?
Thanks in advance.

 

Here are the differences on panelook. Apart from B156HAN01.2 is a discontinued model both panels are mostly identical except B156HAN01.1 is slightly more hungry for power consumption.

 

I have the B156HAN01.2, however I did not know about the 25ms. Is there any screen out there that is comaptible and has lower ms? What is a good ms rate?

My big PC has 2ms on the monitor, so what is good to have on a laptop?

 

Your big PC definitely has TN technology, as it provides the fastest response times. However 2ms is usually a pure marketing, stating only G2G transitions behind these values. A good reading about it here. Response times for IPS are always slower. However this thread has some feedback from people, playing fast FPS games on B156HAN01.2 and LP156WF4(SP)(D1) (which has even slower response times) and reporting almost no problems with that. So basically 25ms should be just fine. Also some general info about panel technologies here, which might prove useful.

 

Discontinued, yes. But there are still places out there to get them. They may not be making them anymore, but they are still available.

Just like what mc_smile said above. You won't notice a difference. 25ms is 1/40 of a second. Your brain will adjust to the slight difference without issue.

 

So I guess the B156HAN01.2 is the one to get when both can be had for the same price? Thanks.

 

For anyone wondering how does the BHAN156 1.2 play,

I've played and finished Bioshock infinite, metro 2033,far cry 3, Need for Speed most wanted (2012) and i haven't noticed any considerable issue.
I also regularly play planetside 2,and i dont have anything to report about it either.

This comes from someone that played games on a 15ms monitor, and recently a 10ms one.

 

Hello

For those who are looking for low Response IPS screen (16ms) this is the one of the best models out there "Samsung LTN156HL01" ,however it's also very hard to get ..
I found someone on AliExpress who claims he have this particular model - So I Make an order and waiting for the shipment to arrive.

Here you can PM to him and then purchase if you like.

*I still Cant confirm the model since I Don't got the shipment yet.
*Will update as soon as I will get it.

Update:
I Confirm the model is LTN156HL01 - the screen is amazing !!!

 

For those who want to know if it's possible to replace an UHD (4K) for one of those FHD, I'm sorry (even for myself). It's not possible.

The 4K / UHD display is LVDS 40 pins connector.

R.I.P. hope

 

I'm pretty convinced now panelook fked up their database and got things reversed, the newer notebooks that are coming out are all using B156HAN01.2 rather than 1.1, and it doesn't make any sense for the newer model to be more power hungry than the predecessor when both have almost identical specs.

there was also another post in this thread that said 1,1 is discontinued


EDIT: there is a site for LTN156HL01-102, which is the panel used on gs60 and g550jk. it's the matte version of 101
http://www.nbkit.com/Wholesale-laptop-_c79749

I messaged them and they said they do have the exact model, and ships from HK.

it seems tempting, but it is on the expensive side and I don't know if I should trust these guys

 

um, no. just from the fact LVDS doesn't even support QHD is already enough to say that it's not LVDS, the highest res LVDS can support is like 2000x1100 ish.

if you ever bothered to read the HW manual you'll know that it's a 4 lane eDP connector

 

So does it mean that we should look for 40 pin eDP connector panel like this one?

LQ156Z1JW03 Datasheet download - Panelook.com

How should I know the spec of the panel to choose? I want to open the lid of the panel and figure out the specs but I don't know what to look for.
I appropriate if anyone can help me with it.

 

that's another mistake made by panelook, all eDP come in 30 pins, but their lanes, which are the cables, can be different, for example if you want a 4k panel you will need a 4 lane eDP, while for 1080p a 2 lane eDP will do. there's no problem if you are going down from a 4 lane to 2 lane, but I don't what will happen if you try displaying 4k with a 2 lane eDP.

this really just means the connector is compatible, but they give you extra wires for higher res.

that said, there should be no problem downgrading from UHD to FHD, since the 4k models all have 4 lane eDP. I just don't think it can go vice versa

 

Thanks for the description. So does it mean that I can get this one?

do you own a 4k model? if so you can

 

If it will help to ensure what we will get, I opened my 4K model and I found this connector:

 

So it seems that it's LVDS. and it's definitely 40 pin. Does 48hz limit is because of this though?

There are two great options for the replacement:
B156HAN03.0
B156HW01 V.4
One is eDP and the other is LVDS. Just waiting to see what is the connection to place the order....

 

Just some review regarding LaptopScreen.com. I ordered a B156HAN01.2 on Friday and received my screen this morning by Fedex in France. That's pretty fast!

However, bad luck the panel is defective... The connector seems to be the reason of the issue, it doesn't plug properly and I had to put back the stock one.

I just opened a support ticket and I'm waiting for their reply. I hope their support is as efficient as their delivery.

 

just ? wow I can't believe lenovo used 40 pin LVDS for 4k...

that makes no sense, LVDS has a bandwidth cap at 2048 × 1536 at 60hz...

 

From what I read, LVDS is only the physical layer and the specification doesn't define how data is to be sent. Therefore, it's up to the manufacturer to determine data rate and encoding. This would mean that Lenovo (or whoever designed the laptop) determined what was to be used and they were limited only by the panel they would use.

 

Do all of these mean that the UHD screen cannot be replaced with any better screen?
I could not find any good 15.6" LVDS panel with top and bottom screws anyway. There is one option which I've found, but it was side mounting...

 

according to y50 manual and parts list the cable for UHD model as eDP (pn 5C10F78811). Not sure why that label says its lvds on that cable... but seein as FHD model is eDP i doubt lenovo would create a lvds based motherboard just for UHD screen.

 

After the B156HAN01.2 I ordered on Aliexpress turned out to be a dud/DOA and having to reinstall the orginal screen, I finally got a refund after the seller never responded to the dispute after 5 days. (I should be getting refund in 10-15 days)

I was going to order from lcdtech889, but it appears they are sold out until Friday 9/5 or Monday 9/8. It also appears as if they only have the Matte version. I prefer the glossy version, but the the Glossy version seems impossible to find anywhere. Hoping they get it Friday and I can order it and get it in this laptop ASAP. I have already been let down once, I'm hoping I dont get a DOA one again! I can't stand this screen any more! It literally hurts my eyes to look at it. I would have paid Lenovo the extra to not have this issue initially...

 

there is a limit on the cable links, which is capped at the said resolution. so far there's no panel above FHD made with LVDS, and I'm more convinced that this is just an error.

actually I take back what I said about 30 pin eDP before, there actually is 40 pin eDP, and the port shown in the picture does have 40 pins... Idk what happened there with the sticker......

 

So it could be the LVDS connector but using the eDP protocol. From what I understand, that is.

 

Interesting... Lenovo Y50 4K Ultra HD Signature Edition Gaming PC WITH TOUCH!

Buy Lenovo Y50-70 4K Touchscreen Laptop, Intel Core i7 - Microsoft Store

 

Alright, I don't want to be that guy who posts something that has been asked a million times, but I have searched and searched and then actually found the search function and used it to search, and I can't seem to find anyone with an answer about the touch screen.
So, I worked at a phone/laptop repair store for two years. I replaced screens all day long. These screens have a digitizer and then an actual lcd display. Unless the y50 is different than anything else, it should be a glass digitizer attached with adhesive and then the lcd underneath. So if no one has tried this yet, I will volunteer myself as a pioneer. In order to do this I need a confirmation that I will be in the history books for this one. Also I need to wait for my next paycheck so I can order the screen.
I believe that I will simply have to use a heat gun and pry the glass off of the bezel. I should find those four screws under this glass. Somewhere, likely on the bottom right or left corner, will be a flex (ribbon) cable coming out of the glass. I will have to work around that and install the new lcd screen. I will then use additional adhesive to re-attach the glass.

If anyone else has tried this or has other knowledge that makes this task not possible, please tell me asap. I will take the glass off in the next day or two just to confirm my theory before ordering the screen. There will be an excessive use of compressed air because there is nothing more that I hate than getting dust under a digitizer.

 

ouch! sorry to hear that. hopefully you get a replacement asap

 

I can't exactly recall where I saw the post, but someone posted before about a 4K Touch edition in the Microsoft store some time ago. Saw the model myself. It went out of stock pretty quickly though. I'm not sure if it was in the original y50 thread that got locked or the Owners thread...

 

Hi guys I just got my new B156HAN01.2 from lcdoled-market and I must say it is awesome. No ghosting or anything. It was really well packed too! You should check out this guy on ebay

... Everything is good, but I managed to broke my screen frame after installing the new screen. It is just the plastic thing that holds the frame tight that got broken when I pushed "maybe" too hard. I am talking about the left bottom side of the frame which the guy in the video pulls out first. It happened when I tried to press it back to place, and now it wont sit tight. Is it possible to get a new frame? Need halp

 

No that's still impossible, the pins have different I/O for each

 

I mean...the Cover glass is glued on, so unless you can glue it back…idk how you are gonna deal with that

 

Hi guys,

I'm trying to return my laptop, but if I have to pay 15% or whatever, I'd prefer o adventure in the replacement here.

To help somehow this dabate abour eDP and LVDS, this is the photo of the display's back

What are our options for this screen? I'm not looking for a 4k replacement. A FHD with a good color gamut is the ideal already.

 

If anyone wants the stock innolux panel I have one to sell for $40 shipped. Has about 5 hours of use, ships from the US, and I accept paypal.

 

dude, can you at least try to take a picture with texts not flipped up side down ya know? I appreciate the help tho...

 

Do you still have the LP156WF4-(SP)(D1) in stock. My ticket number is 186924. I was told I have to purchase the U1 model which is glossy and apparently $20 more expensive.

Thanks

 

From what I read, LVDS is only the physical layer. It doesn't specify what the I/O is in the LVDS standard. That would leave the I/O up to whoever designs the circuits.

Quote from Wikipedia: "Since LVDS is a physical layer specification only, many data communication standards and applications use it but then add a data link layer as defined in the OSI model on top of it."

 

from http://www.vesa.org/wp-content/uploads/2010/12/DisplayPort-DevCon-Presentation-eDP-Dec-2010-v3.pdf

 

Is it actually glued onto the entire lcd like the newer smart phones or is it just glued around the bezel?

 

Guess I was wrong.

Anyway, since we were referring to that pdf I figured I'd post another thing from it that may be helpful.

 

The one thing that would make this laptop better than all the others for me is if the screen was 120hz and had that backlight strobing... :/

I'd gladly pay an extra $300 for that, even though it wouldn't cost nearly that much to implement.

If only it had that... Hell, I'd accept having a crappy TN panel if I was able to get that.

 

So is a 40-pin eDP even possible? I still don't understand that much. Obviously our connector is a LVDS, according to that one guys laptop picture (assumine he for sure is on the UHD laptop, not a FHD laptop).

 

there is a 40 pin eDP, but we just don't know if that LVDS on sticker is actually real or not, because LVDS has a bandwidth limit


on a side note, HAS ANYONE PURCHASED FROM dvdsuper999? THEIR LINK IS RIGHT HERE B156HAN01 2 1080p LCD Screen Display 15 6" for N156HGE EA1 B156HTN03 4 EDP 30pin | eBay

just wondering if anyone tried that seller before, making sure it's not one of those compatible model bs

 

So basically we don't know if it's a 40pin eDP unless someone eventually has a screen and tries it?

 

basically yes...

although there is a slight chance that it may be as well LVDS.

remember, the 4k model uses a pentile screen, something samsung knows well to cheat on production cost. although nominally it's 3840x2160, the subpixels are actually white pixels that adds up the total number of pixels, which means the panel has an effective luminance resolution of 4k, but in reality it doesn't have 4k pixels, which means even with a bandwidth cap on LVDS, with a limited refresh rate it can possibly still run

in the end, the best way is still to have someone try it out...

 

In this case I would say the chance of being LVDS is more, and it would be the reason for the hardware limitation of 48hz (as Lenovo recently stated that it's not a software lock, but a hardware limitation). I feel that I would trust the label somehow. So let's say if I would want to try a LVDS, 40 pin connector panel, do you have any recommendation? since I am a graphic designer, the color gamut is the most important spec. and high contrast ratio. I would say is there any option close to Dell XPS15 screen?

 

I mean B156HW01 V4 is a 6 bit 95% wide gamut panel that uses 40 pin LVDS... but it's a TN panel Idk if you would want that

I think it's too early to call for a conclusion that the interface is LVDS, I wouldn't call on it until someone tries it out.
so far I know no panel beyond FHD that would use LVDS really

also someone please confirm this with me
HAS ANYONE PURCHASED FROM dvdsuper999? B156HAN01 2 1080p LCD Screen Display 15 6" for N156HGE EA1 B156HTN03 4 EDP 30pin | eBay

 

But B156HW01 V4 mounting is from sides (according to panelook, and some online images). and y50 is up and down... so it won't fit. Am I correct?
