Are there any 18.4" quality screens?

I actually sent them an e-mail enquirying about the LTN184HT02 before I got a chance to see your post. It's always the same story with the online companies: they list every possible and imaginable screen to give the idea that they are a huge retailer who has everything, but in truth they only have a small fraction of they list in stock.

 

That's a shame the AW screen is at least halfway decent or even a little more than halfway maybe 70% decent and has good horizontal viewing angles which I think are the more important ones vs Vertical viewing angles as its easy to tilt the screen higher or lower to compensate for the poorer vertical viewing angles. Almost all LCD's suck at vertical unless it's IPS. Like 2 more weeks and I get to trade my desktop and cash for the Alienware portable desktop (notebook) m18x. I'm just worried he voided the warranty because he replaced the stock fans with some higher cfm higher static pressure Japanese fans with the same dimensions and connectors. If anything they should increase the warranty they provide more air flow and run quieter and the higher static pressure directs the air with more force in 1 direction but you know how companies are when they want to get out of warranty duties. But this thing still has 3 years and 2 months warranty left.

 

Ask for the stock fans. If you have a warranty issue, you can always swap them back.

But keep in mind, for High OCs, if something fries, it wont be under warranty, typically.

 

Kabatik i would like to show you something

 

Please don't post pictures of anything that has "bulging veins" in it.

 

hahah maaan nooo it it NOT that jeeez

It's this ! I just purchased it yesterday and they called it: --->> LCD Laptop Screen 18.4" EAGLE3 Samsung

this is description according seller :

Manufacturer refurbished: An item that has been professionally restored to working order by a manufacturer-approved vendor. This means the product has been inspected, cleaned and repaired to meet manufacturer specifications and is in excellent condition. This item may or may not be in its original packaging. See the seller’s listing for full details. See all condition definitions

I phoned them up and asked them how the sreen is and they said it is Matte which is PERFECT
And when I asked them if it's LED they said it is not led .. so i really DO NOT NOW
they wrote in description LTN184HT02 and claiming it is not LED RGB ??

katabatik they said even this :
This component is confirmed to be a fully compatible replacement part for the below products, but may also be suitable for use in other computers. Please check the high resolution photo and manufacturer part number if in doubt.
SONY VGN AW21XYQ

MPN: LTN184HT02

 

Where did you purchased it from?

If it's LTN184HT02 it has to be LED. Question is: did they swap the references? I know theses guys work with tons of references, but LED vs CCFL is of paramount importance to compatibility.

How much are they asking for it? Is it new?

 

I have purchased it on ebay but here is original website and i realised that they do not charge for postage from website but from ebay they charged me 6 pounds ..

They said it is matt so it HAS to be RGB LED CCFL is only glosy i think
Why they call it EAGLE 3 ?

What about this ? So it is NOT only matt
LTN184HT02 18.4 Inch WUXGA Glossy Laptop LCD Samsung

Here is LTN184HT02 for ridiculous price ..

http://www.ebay.co.uk/itm/NEW-18-4-...804?pt=LH_DefaultDomain_0&hash=item230f88b4e4

 

Sorry to break the news, but I doubt that that is an original Samsung screen For that price it is probably one of those asian screens that are all over the internet.

The eBay link that you sent is from some guy in China who is selling chinese screens for 10x more than they are worth. Notice that he says that he has 20 to sell (odd, given that this screen's production was discontinued quite some time ago) and nowhere does he mention that it is Samsung.

Given that they are not the originals but are only suposed to have the same specs as the original in terms of size, resolution, backlighting type and connection, they are free to make them glossy or matte.

I'm going to check those guys from Canada. The price would be what you'd expect for the original. The keyword here is "RGB LED". Only the LTN184HT02 was RGB LED, which is rare. Most LED screens are WLED. A dealer who knows his stuff must be able to provide this information along with the complete model number and a serial number.

As I said, the only way to find this screen nowadays is being lucky enough to find a refurbished unit or some screen belong to and old stock. There is no way some can have 20 of them laying around to be sold.

Still, do let me know what you think of the quality of your new screen. Who knows? Maybe it isn't as bad as the Chi Mei.

 

But chi mei making only glossy no?
You remember when I asked.you where.do you live..?
So I was planning to deal with you
If I will be unable to fit the screen or connectors will be diff. would you buy it?

 

Chi Mei makes both glossy and matte. However, matte screens are not as easy to find as glossy.

I am only interested in the original Samsung. But please, do let me know how many pins the screen has. I haven't been able to confirm if our Chi Meis are 30 or 40 pin.

 

I used to own a VAIO AW laptop, the screen was one of the best I have ever seen. Now I am using an ASUS N53SV, changed my screen to an AUO B156HW01 V7 by myself.

 

Just got home and received screen today and took picture from rear
Do you think this is not original ? when says samsung.. ?

 

Is it new or refurbished? If it is new I'm still not sure it is the a genuine LTN184HT02 (having the Samsung logo doesn't prove all that much).

Please, do give us feedback on the image quality. It should be noticeably different from the Chi Mei - especially the colours - if it really is the Samsung.

I'm eagerly waiting for your feedback.

 

uum that will take a while cos I need to figure out how to disassemble display on my acer + if connectors not gonna match ?

 

THAT might pose a problem... The original LTN184HT02 had a 30 pin connector and the Chi Mei spec sheet I pulled from the net says ours is a 40 pin connector.

Be carefull with the connections. You might fry the mobo or something else. I've read a thread on the forum of a guy who tried to use and adapter to fit his screen and fried something.

Anyway,

1) Check the connector type of your Chi Mei

2) Check the new screen's connector

3) See if they have the same number of pins AND the same pin layout.

If they are different, let me know the type of connector that your new screen has. I'm going to talk to my Clevo dealer tomorrow and I'll ask him if there is any workaround in these situations.

If at any stage you are unsure of how to proceed, take your Acer and your new screen to a good pc repair shop that assumes responsability for any damage caused to client's computers during repair and have them do it for you. Compared to the price of a fried laptop, whatever they charge is going to be cheap.

If I can be of any help, I will gladly help you to the best of my knowledge.

BTW, there are lots of Acer screen replacement video guides on YouTube. Not sure if there are any for your specific model, but have a look around.

Also, check this out:

I really do hope that you bought a true Samsung screen and that it is compatible. It would have been a great find. Good luck.

 

I just want to share this website:

Global Panel Exchange Center - Panelook.com

You can find answers to most of your questions regarding to specs of screen panels.

 

The Chi Mei N184H6-L02 has a 40 pin connector. It an Ipex connector with the following reference:

STE-I-PEX-20455-040E-12

The Samsung LTN184HT02 has a 30 pin connector

There are adapters but I'm not sure if they really work.

Thanks for the link philideng, but there is no info on the LTN184HT02 on that site.

I've done a lot of digging today and as far as screens replacements go, I've concluded that it's a jungle out there: a lot of sellers are clueless on the exact specs of the screens they are selling and just say whatever comes to mind, hoping to push the product. Prices vary wildly. I've seen differences of more than 100% for the same screen. There are even comediants (let's call them that way ) on eBay who are trying to sell Chi Meis with the LTN184HT02 reference for nearly 1k

GalaxySII,

Unless you can fit the monitor on your Acer and make it work, I believe I'll stop digging and settle for calibrating my Chi Mei, hoping that it sucks a bit less. Sellers do not provide reliable information and buying without seeing the screen first is a shot in the dark.

 

Katabatik
This is chi mei LCD fitted in my laptop ...
What do you think ? There is ONLY one connector .. On samsung there are 3 connectors !
Is it different connections?

 

Just a suggestion - if Samsung has 30pin and a few extra connectors, and your Chi Mei has 40pin it is possible that you have all the needed lines, but in one connector.

 

You got me there 3 connectors, uh? Are they all 30 pin? I have no idea what they are for and I'd avise you against experimenting before knowing their function. Perhaps the folks at the Sony AW owner's lounge can shed some light on the subject.

@katabatik
I found very interesting site!
They describing compatibility !!

N184H6-L02 - http://pantalla-portatil.net/pantallas-para-portatiles-184-LED.html

 

Just a caution:

Meaning compatible does not necessarily bring you the same color and contrast performence.

 

You took the words out of my mouth. Hence the importance of being the original screen that fit the Sonys AW.

 

GalaxySII

It seems there are two versions: LTN184HT02 and LTN184HT02-S01. According to the pictures you bought the later. This is site is, by far, the one that has the better information about the products they sell. As I said before, most sellers know very little about the product they sell and just want to push whatever is in stock.

Saddly, if our Chi Meis are 40 pin, it will be very difficult/impossible to fit them in our pcs. Even last night I verified, yet again, how much the Chi Mei sucks. Dark scenes in movies do look terrible. As a last resort, I'm going to calibrate the screen, hoping that the color rendition improves slightly. However, TN screens are a PITA to calibrate.

 

That's why I spent $200 on a 96% aRGB 15.6'' FHD panel last summer.

Now I'm planning getting the VAIO Z panel for $400 and try to fit it to my 13.3'' laptop (since the Z's panel is 13.1'')

 

I already posted it on the previous page, never mind

 

philiden

I dont thik you right !
How can not bring me same perform. or contrast it IS DISPLAY ..
And how can it affect that I will be looking at screen from different angles and I will not see x-ray ??
I had this screen before I know what is it and how is it ..

 

there are two versions but glossy or matt noothing else
i have checked this properly and there is no SIGN that samsung made LTN184HT02 and LTN184HT02-S01
All websites says it is discontinued

If u want calibrate go here : http://www.lagom.nl/lcd-test/

 

Just found PDF of chi mei LCD

 

Cannot find pdf for samsung .. pity
but I hve found great site where they proved me that I have LED!

Hi, I just said what is generally true. Unless it is the identical panel (same model number), I will never say the replacement panel gives the same performance. Last summer I was looking for AUO B156HW01 V7, and I bought one saying "replacement panel for B156HW01 V7" and I ended up getting a panel from LG, which does not have the wide gamut I wanted from B156HW01. So I am just saying based on my experience.

In the future when I buy panels, I will first check the specs of the particular panel I am going to buy, then confirm with the seller that they are selling the exact model, not any "repalcement".

 

Exactly.

philideng,

So, in your opinion, the panels para equip the current Sony laptops are still the best?

 

I would say currently, only the Z2 series. The screen is almost perfect, 96% aRGB with FHD. It is not IPS though, otherwise the price would be unaffordable even to business users. SA only has a so-so panel (a little less than sRGB, but it has 1600x900 resolution. As for the SB, the panel is IPS but the color is not good either.

And the VAIO AW series was discontinued. I think the screen on the AW is unbeatable as well. Years ago I heard it has 127% aRGB but that just sounds...so I would say I'm not sure.

 

I tend to give more importance to colour reproduction precision and good viewing angles than to an extremely wide gamut, which has its own problems in applications that are not colour aware. This can be solved with good sRGB emulation, but I'm not sure that even exists outside desktop monitors.

IPS has one disadvantage: it usually has agressive AG coating making the pictures look granny and text fuzzy. I owned a Dell IPS desktop monitor and returned with because of the granny AG coating.

 

I called these guys today. They said that there are no alternatives to the Chi Mei. They even advised me to send a picture of the back of the screen to fully check compatibility.

As I said previously, it is not sufficient to be 18.4" LED FHD to be compatible. Connectors must be compatible and their placemment (left, right, top) must also be the same. Then, there's the issue of revisions. The same model might have had several revisions and they might not be fully compatible among them. The electronics must also be the same.

In a nutshell: we're stuck with Chi Mei. Most sellers just want to sell whatever is in stock. At least these guys were honest (as well as the guys from Germany).

I'm waiting for my calibrator to arrive. I don't have much hope that it will make much difference, but I will post my findings here or on the P180HM owner's lounge.

 

OK !!!
It's done am finished with research anyway ...
I thought someone do customizing or experiments with screens obviously not ..
BUT I will keep screen cos I know this is LED and there is no better 18'' in the world ..
and now, i am watching cheap AWs on ebay .. even with faulty screen and will buy vaio AW ..

About that calibration .. I have posted link did you look at it?
And all tell you it is not gonna help any better cos viewing angles are and will be always bad ! (X-RAY)
END

 

Man. this was a great thread! Very informative!

 

So, there's no chance to rewire the cable, as not compatible at all?

 

Rewiring is a "at your own risk" thing. In order for that to have any probability of success, you'll have to have the detailed pins assignments of both connectors and pray that voltages are the same, etc. I know that there are 40 to 30 pin converters, but I have no idea if that works. If all that could go wrong was a blank/black screen it would be worth a try. However, it is not altogether impossbile to fry a mobo doing these kind of experiments :-(

GalaxySII,

I understand your frustration, trust me. I did see the link you provided, but I am talking about calibration with a Datacolor Spyder probe. As you said, viewing angles will always suck, because that is inherent to the screen. If you want really wide viewing angles you'll have to go IPS but there are no 18.4" IPS screens and the IPS offer in the laptop world is still very limited. IPS also has the problem of having hard AG coating which makes images look grainy.

An old Sony AW might be your only hope to own an 18.4" laptop with a good screen. I thought of that too, but second hand AWs are rare and overpriced. Saw a guy selling one on Amazon for £1200. For that kind of money you buy a professional 24" or 27" desktop monitor. An AW with a broken screen should be cheaper and might be a good deal.

However, bear in mind that not all AWs came with the LTN184HT02-S01. Some came with the LTN184HT03 which was CCFL and notoriously dim. Others came with the LTN184HT02, (one comnector instead of two). As the guys from Madrid said: knowing your laptop's model is far from sufficient to know the exact replacement screen.

 

Yeah, sadly it is this dangerous I was looking to rewire a DELL M4400 RGB LED, but it's near to impossible. Not only the backlit is different, but the connector is proprietary and the pin layout is a mess. There are people who have gone CCFL to LED, but then you'll still have to deal with the wire mess. Someday if I manage to find someone to take a look at both schematics, probably just to rule it off, but there is a very small chance to happen as well. After all M4400 has been shipped with all the backlit options - Single, Dual CCFL, LED and RGB LED (as far as I know, I could be wrong on single CCFL).

Can u phone them up again and ask them for specification manual pdf for LTN184HT02,?
I found for chi mei but couldnd find for samsung .. And I will compare pin layout..
Thnx

LTN184HT02-A01 is NOT LED and it is wrong there is only LTN184HT01-A01 or LTN184HT01-A02
LTN184HT02-S01 is LED Anti-Glare !

Edit
I have checked and this mine IS LED but different revision S01 is lower than A01
if it is not led, it would have two cables on the bottom for power for lamp bulbs but there are not there ..

Edit 2
Katabatik
I have vaio aw manual and there are switches when somebody replacing different screens !

Edit 3 !!
That website is full of rubbish !!

Edit 4
LTN184HT02-A02 does NOT exist there is LTN184HT01-A02 !!

 

Thread still going? Here’s another 18.4 LCD Laptop: Eurocom Leopard 2.0

The Leopard's 18.4-inch display is a full HD (1,920 by 1,080) panel with glossy edge-to-edge glass. Color quality is outstanding and blacks are dark and solid, but the panel's reflective surface can be distracting. That said, the big screen is ideal for gaming, movies, and viewing multipage documents.

The Leopard 2.0 is huge; it measures 2.8 by 17.3 by 12 inches (HWD) and weighs in at 12 pounds, which is a bit lighter than the Alienware M18x

Unfortunately, Eurocom will no longer be using the P180HM chassis, according to a company spokesperson. Instead, it will move to a 17.3-inch form factor, which means the Leopard 2.0 will be phased out in the very near future.

 

Katabatik
Here is chi mei 40 pin assignment on the left and LTN184HT01-A02 on the right .. couldnt find LTN184HT02 pdf ..
But as I checked this is completely identical
UNIVERSAL pin assignment !
those last ten on chi mei belongs for LED power and on LTN184HT02 they are separated ill bet !! That 8pin MAY BE

 

The Eurocom Leopard is the same as the Clevo P180HM.

 

I wouldn't go as far as to say "universal". I too searched for the LTN184HT02 pdf without success Remember that LTN184HT01 is CCFL.

Have you tried to contact Samsumg and ask they if they have a service manual or a data sheet with the LTN184HT02 pin assignment?

As for those on-line sellers, as I said, are clueless, for the most part, clueless about what they are selling and couldn't care less. Those Xiamen guys say that "TN184HT02-S01 18.4" 1920 x 1080 2CCFL Glossy LED Backlight LCD Screen". "2 CCFL Glossy LED". ? CCFL and LED on the same screen? That must be some cutting edge technology, proprietary of Xaimen Astonish Forest... Astonishing indeed

 

You wrote same text twice
Yeah it is very hard to contact samsung and they will never provide such thing, some pdf,they would go: ''wth he want from us'' I have those pdf from some russian web but they doesn't have LTN...02 in stock so no pdf.. I have emailed them..
Well nice screens vaios .. do you plan replace screen or whole laptop?
Do you think that we would be able to swap screens? Or you lost hope?
