Y50 Replacement Displays Compendium

Good question. I personally don't know, but a different panel is usually a different panel. Unless you know for a fact that they just renamed a panel for a different manufacturer.

 

Ok, lucky that I ordered that B156HAN01.2, as the LG LP156WF4 (SP)(D1) is not happy. Here's what I recieved:


It looks bad, like every other pixel row line is black suffers temporary burn-in. Yes burn-in. Here is the boot screen after having it up for a few minutes. It's showing the windows from the previous log-in. It does go away if you let the panel sit for a few minutes, but wth?



Maybe the IPS versions of the Y50 come configured differently or other components in the notebook need adjusting or calibration, I don't know. The stock screen works fine. It's almost like it's teasing me. This is really frustrating. Any thoughts or ideas on this?

Such a good notebook, love it when using external monitors. Hate to use it with it's own screen. Unless anyone has any suggestions, guess I'll wait for the B156HAN01.2.

 

Hold the phone. And now it's fine...?

I hooked up the LG LP156WF4 (SP)(D1) to give it one last test. It started out with flickering and burn-in from previous session and then it all cleared up. No I didn't do anything between the burn-in and it clearing up. Um.... do IPS panels need a warm up period when you first use them? It looks great (read: awesome) now, sharp, bright and OMG viewing angles! I'm going to do some testing and make sure it doesn't lapse back.

If it stays like this, i am officially loving this notebook again.

 

Just received and installed my AUO B156HAN01.2 Check the image comparison here: http://forum.notebookreview.com/ideapad-essential/741832-y50-thread-635.html#post9714571

 

Great, once I get home I'll add this to the first post. Thanks for sharing.

 

My guide had been updated and i posted a YouTube video. Enjoy.

Will add comparison pics on panels later tonight or tomorrow.

 

Great video, shillydwagon!! Very helpful! Thanks for that.

But that said, i'm also a bit mad about it, as i was almost sold on the P34g v2 and now...
Have to think another round about it, but the Y50 in my preferred configuration is not in sight yet here in germany... I do not only want, but i really need a new laptop within short time, as my macbook's graphics card has died (typical fail on the 2011er model unfortunately) and i only can run it on the integrated Intel GPU anymore...

Please keep us updated about your screen's burn in problems and if you gonna keep it...

 

Ha. =) Well, for the P34g v2 (that was high on my list too. ) you can factor in that the replacement screens are a bit tricky to get? Otherwise, this thing (Y50) rocks now. Maybe get the touch and make sure you get a decent screen?

The burn in or whatever it was is gone. Maybe the 30pin was a tad bit lose? I did completely re-do it for the YouTube video, so that was done after the burn in issue resolved itself. I have been using this screen for a couple hours now, no issues. I will post if they crop up again. Still a very odd. Comparison pictures in a few.

 

The new LG LP156WF4 (SP)(D1) is rocking. It's matte, but very bright and the colors are great. Using the notebook on normal display setting, default brightness/contrast/gamma and 100% scaling. I can see text with no strain and it's very clear and sharp.

Here are some comparison pictures between the stock InnoLux N156HGE-EAB, TN panel and the new LG LP156WF4 (SP)(D1), IPS panel. Stock TN on left, LG IPS on right:

Your default panel was an Innolux? I thought it was either AUO or CMN?

 

Any difference in battery life with the new panels?

 

Just wondering if you encountered any "warranty stickers" while taking out the display?
Just wondering if we could replace it and if we run in to any problems, just put the old display back and send it in for warranty

I watched the video and didn't notice any but to my understanding, this is the second time you're putting it in so I'm curious if there was any on the first time of taking it apart?

 

I did not encounter any warranty void stickers. However, the piece that holds the cable in has clear edges that can tear in a jagged pattern, mine did along the top.

 

Sorry, I hardly use it on battery and more of a mobile computer between sites. For what it's worth, the new panel is rated at 150% the power consumption, 5.58W (Typ) vs 3.7W. http://www.panelook.com/modelcompare.php?ids=19846,22455

 

Same panel, Chimei Innolux (CMI) changed name to Innolux: reference

 

Many thanks shilly, the LG looks beautiful. I'm perfectly happy with matte too, so I think I'll be ordering this as a replacement screen when my y50 finally gets in. They pushed shipping from 7/10 to 7/16 =.=... Ordered from Lenovo Canada on 5/27. Atrocious really.

 

I know you guys are talking about the y50 but any info in the y40? I heard from users that the screen is also lackluster so I wonder if it can be replace like the Y50.

 

Oh boy-this is a massive problem for me if that equates to a reduction in battery. Somebody please confirm

 

Your comparison pics are amazing, like your video is. :thumbsup:
Didn't think that the replacement would be that easy to do.

Only thing that worries me a bit is maybe voided warranty? I mean, if there would be a problem down the road with something that has absolutely nothing to do with the screen, they can't deny the warranty, can they?
On the other hand, i wouldn't be too surprised bout that as some (many?) companies would take that chance to deny any support...?

Do you think you were able to do it without Lenovo recognizing your customisation?

Shillydwagon, can you PLEASE test your battery life with medium screen brightness and surfing the web, youtube, a bit listening to music, office work...? Would be very appreciated...
I'm with 'ycon' on that. If battery life would be reduced significantly that would be quite bad...

 

It's also about 150% brighter. Makes sense that it uses more power. Correction, 50% brighter(on both our parts)

 

Hi guys,
first time poster here. I'm also thinking to swap monitors when I get mine. I'm guessing that battery drain would depend on brightness setting so the swap it self wouldn't change the consumption. That's it just happy to be here .

 

double post

 

Have to admit, that makes kinda sense.
But a actual battery life test like in my afore mentioned post would bring us confirmation.

Shillydwagon, if you could provide us with this info, that would be very helpful, mate!

 

I'll see what I can do. Stay tuned.

 

If you are uncomfortable with potential warranty issues, I wouldn't do it. If you did and had something go wrong, not having to do with the screen, I would put it back to original. They wouldn't pop off the screen for a failed HDD or motherboard, you know? And if they determine that the issue calls for a replacement notebook, you still have your screen.

And to re-iterate, messing with the panel probably voids the warranty on the panel and potentially the whole notebook. So, you have to be comfortable with that possibility.

 

Thanks man!

Did you inform Lenovo about your replacing of the screen or do/did you just risk voiding you guarantee?

I think about informing Lenovo about my intention and to document it with pictures or so to bring maximum transparency into this procedure for them, so that if there would be a problem (which would has nothing to do with the screen) somewhen down the road, they would know, what was done on the computer before and there was no fail on my side...

I heard about 'tearing' effects on the original panel. Did you have these probs too and if yes, are they gone with your new panel?
Did your ghosting probs appear again?

Sorry for asking so much, but i guess you almost have sold me now on the Y50 though...

 

No, I did not inform Lenovo. I am comfortable knowing I most likely voided my screen warranty and maybe my notebook warranty. I tinker with things all the time. I really hated the old screen. I didn't use it without a monitor, at all, after the first couple of days. It really is amazing how I loved it while using monitors and hated it with its own screen. I am on battery right now on 60% screen, still comfy to use.

I don't think Lenovo can assume the risk associated with people replacing their own screens, but you never know. Let me know what they say.

I seriously didn't use the stock panel enough to notice tearing. It was awful, period.

The ghosting issue never came back. At this point I am inclined to believe I did not seat the cable all the way. Which, of course, I am embarrassed about. But hey, if someone else runs into that issue, at least they know! Right?

The way I use the Y50 (site to site with keyboard-mouse-monitor setups on each end), this panel works great for me. Actually I used it in the kitchen last night, away from my computer desk monitor, gasp!

 

Re: Lenovo warranty

I recall chatting up a US Lenovo agent a couple of years back, regarding the warranty on a ThinkPad after an LCD replacement.

I was told that it was fine, but the new panel will be excluded from the warranty.
Basically taking apart your Lenovo laptop did not void warranty at the time for upgrades: HDD, CD, Wi-Fi, BT, LCD, etc.

Speaking to Dell on the same topic in on-line chat basically came down to: Touch one screw, and your warranty is a goner.


Please note this is out-dated info, but you can always pop into an on-line chat for your manufacturer and ask them the question directly.
It may help to post your laptop serial number to them - warranty terms would be different for "consumer grade" laptops and "business grade",
as it is typical for businesses to have their own IT departments, and tying their hands with warranty issues for simple upgrades and on-site troubleshooting is impractical.

Observations and Thoughts:
Would rather use this panel at 50% brightness than the CMI panel at 100% brightness. Noticible screen brightening in steps when going from dark to light. When openning and maximizing Word with a dark desktop you can see white in Word gradually brighten in about 10 steps. Same with minimizing it again, whites darken in steps. Maybe that’s a power saving feature? This effect is not noticeable at full brightness.

This dimming/brightening is rather distracting while web browsing. About an hour in added one more up arrow to 60% brightness, much more usable but still distracting. I don’t think this screen likes lower brightness levels. It stops being noticeable at 80%. This does not happen while plugged it at 40%, must be a power saving feature.

Hope this helps. Ok, done with Y50 projects now. :hi2:

 

Hello! first time poster here. I have seen the instructions to remove the screen on non-touch models with bezel around the edges. The touch-models are unibody glass with no bezel. How would I go about replacing the panel? Also, would the touch function work with replacing the panel?

 

Finally got my LP156WF4(SP)(B1) and replaced the screen. It looks much better, highly recommend spending the extra $100.. going from TN to IPS makes a big difference and I think viewing angles are a big deal on laptops.

 

Are you wanting to put a 4K panel into a laptop that previously had an FHD panel? Or are you wanting a replacement for the 4K panel that Lenovo is selling?

My answer to either question would be: why?

 

I'm glad I didn't see this thread before ordering my Y50 4K. I probably would have gone with the FHD model and then replaced the screen. But I was able to get the 4K model with a 256 GB HD from Newegg for $1,299, so if I had purchased the FHD model with the 1 TB hybrid drive, I would have spent at least $100 putting in an SSD and another $100 on a new panel, so I think I'm going to be happy that I went ahead and got the 4K panel for not much more money. It should be delivered any minute. Can't wait.

 

Are you encountering the same sort of gradual screen brightening when going from dark to light as Sillydwagon? I know that he has a LP156WF4(SP)(D1) panel instead of a LP156WF4(SP)(B1) I'm not even sure what the difference between the two are. Could someone clarify this?

 

Panel Specification Compare - Panelook.com

Less brightness: 300 cd/m2 (Typ.) vs 400 cd/m2 (Typ.) (Is it glossy? D1 is matte.)
Wider viewing angle: 85/85/85/85 (Typ.)(CR≥10) vs 80/80/80/80 (Min.)(CR≥10)
More power consuption: 7.28W (Typ.) vs 5.58W (Typ.)

 

Okay, thank you. I'm still curious about the whole screen brightening issue and how noticeable it actually is. It may be a deal breaker for me and I may just go with the B156HAN01.2 panel.

 

I don't understand why you guys would be so limited in options, laptopscreen carries a plethora of Samsung PLS screens.
LTN156HL01-101 (Fun fact, 102 is used on gs60 ghost）for example is a pls panel used on the Asus q501l and laptopscreen is selling them at 90 bucks. So why pay $140 for a screen when you can get better ones for less? LG and auo aren't the only options and there are tons of better ones
LTN156HL01-101 Replacement Laptop LCD Screen From $79.99 Brand-new screens.
If you want reViews simply look for Asus q501l or gs60 which a lot of you should be familiar already

Btw theSe all use 30 pin eDP so there's no compatibility issue

 

Thanks for bringing this up. I don't have any previous experience with replacing displays so I just assumed my options were limited to what people were suggesting due to compatibility issues. But it did seem strange to me that people weren't considering other options. I think I may just go with one of the PLS screens.

 

I think it's part of the energy manager app.. If I go into it and turn it from high performance to green mode it'll turn down the brightness in steps but I don't notice my screen doing it otherwise even when going from dark to light areas.

 

So I just ordered the LTN156HL01-101 PLS screen. I should get it by next Thursday or Friday and will update you guys on some comparison pictures!

 

Very much looking forward to this. For those curious, I ordered my Y50 from Tigerdirect and also confirm (others already have) that it's just a Chi Mei screen and Tiger is incorrectly labeling it. I had a long call with their support about this, imploring them to change their specs. They refused, and instead are sending me a replacement laptop saying it may fix the problem (face-palm). That said their fully decked laptop (with 1TB drive) is priced at $1099.99 which is the cheapest I have seen. Lenovo Y50 Intel Core i7 16GB Memory 1TB HDD 15.6 Notebook Windows 8.1 64-Bit - 59425651 at TigerDirect.com

I am using the savings to buy a new replacement screen. I looked up the Intel HD Graphics card in the Y50. In an Intel forum an Intel Support Rep said the following "The driver we currently have supports 8, 16 and 32 Bit under color Depth which means 8, 10 and 12 Bits per color correspondingly. "

heibk201 makes a good point, we really can work with almost any 4 screw 30 pin eDP screen. Does anyone know what the best screens are out there or how to track those down? As great as laptopscreen.com is, it doesn't allow for easy browsing.

 

Whoa. Does that really come with 4GB VRAM? Not that it's crucial to me, but if the display info is wrong, that might be too. I think I'll have to get this one and replace the screen, too. Awesome deal, though; thank you for posting it.

 

Yes it's the 4GB version screenshot included


There is no IPS version of the non-touch 1080p version of the Y50. Lenovo support claims there are no plans to have an IPS one. After searching around I felt the tigerdirect.com Y50 was the best bang for your buck if you don't want 4K or Touch. If you do order it, please do the same thing I did and tell them it's not IPS. Maybe if enough people tell them, they'll fix things. The fact they are so stubborn regarding their spec sheet is mind numbing. I spoke to supervisors and then managers including tech support. They just dont care.

 

Can't you file a complaint with BBB for false advertising or something? I mean they are blatantly lying and sticking with it even when its pointed out...

 

I will probably do the same, or go with the one of the others that looked great (or something seemingly compatible on laptopscreen.com) when I'm back from a trip next week... just so disgusted with the default panel, it's really unfortunate that they didn't at least include something better and increase the price by $50. Oh well. At least replacement is a breeze

 

usually screen dealers don't give info on what type of panel it is and databases such as panelook are limited. the best ways to figure out screens are

1. learn to decode each brands' naming patterns
2. find a laptop with an IPS panel and look at its panel serial number and search it up for similar products

 

I think that even going three levels as I did wasn't a substantial enough escalation for them to take a look at things. At the end of the day, most consumers will never know the difference. They'll just think it's a crappy IPS panel. I told Lenovo as a last act of desperation. Lenovo said that they cannot be 100% on what a reseller sells. Apparently there are already over two dozen different variations of the Y50 ranging from different components too. For example my Y50 has a synaptics trackpad, others have Elan. I have a 7160 Wifi card, others have 3160. It's very annoying because most spec sheets don't list this information - especially the 2gb versus 4gb on the 860m.

They insist on sending me a replacement machine, I will abide them. When the replacement arrives and it has the same panel maybe then someone will listen.

 

Hi,

I've a little skeptical about the resellers information about the screen. I will only buy a Matte IPS (I used it a fair bit outdoors).

Does the B156HAN01 2 come in a matte version? If not, which one does?

 

That is the matte version. 1.2

 

So what is the highest color gamut or lowest response time IPS display that will probably fit in this model?

I will gladly buy it and try it out and report the results.

I am worried about the high response times on these IPS panels 25-35ms seems ridiculously high. I am used to a 1ms TN panel. Will i notice this difference with input lag or ghosting etc?
