Laptop Screen Upgrades

You can't sell on this forum because you don't meet the membership/posting requirements.

 

where do you guys recommend buying a laptop screen? i have a sager and cannot find a reputable place online. thank you for any help.

 

I bought my IPS for my Zbook 15 G2 from Laptopscreen.com. It took a while for the screen to get here but they're pretty reasonably priced.

 

Please ignore, just found the thread with all the info i need.

OOOOPPPPPSSS!

 

Ya what is that all about anyway? Some kind of new port standard? I would imagine someone is going to be making adapters for that soon.

 

I recently opted to go with NE156QUM-N66 .... all I can really say is it's a huge improvement over my now former panel.. The full write up@ http://forum.notebookreview.com/threads/nh58raq-np6855-screen-upgrade-experience.833976/

This model of laptop isn't mentioned anywhere on the web other than for sales of it.

WARNING tons of details in the post.....from panels to cabling and comparisons to experiences with different sellers.

 

Anyone care for a GT73VR (17.3") with a 18.4" 4K screen upgrade? Lol

https://www.dropbox.com/s/r3yw67bdbtul2hp/20200902_145736.jpg?dl=0

 

I installed a B156HAN04.2 into a Dell Precision 7530 and it worked fine, no issues. Nice colors on this panel too.

 

I would ask for picture proof before they ship it. I have had aliexpress send me a counterfeit panel. I have had nothing but a bad experience in every regard you can think of with them.

 

Hi,
unfortunately my screen in DELL PRECISION 7740 is broken, mechanical damage and I have to replace the screen and the question is whether I have to put in the same model or it is possible to upgrade to 4K screen
thx to answer.

 

First figure out what screen is in the laptop by using wininfo
Take the model info to panelook to find the size / dimensions
Sort the panels by size and compare them for features you're interested in i.e. original vs 4K models
Match up the EDP cable pins as some mobo side sockets have a 30 pin w/ 30 pin panel or 30 mobo to 40 pin panel (option) or they're 40 pin to 40 pin

I swapped a FHD to UHD using these methods and it's working fine.

 

not just ali express. ebay and newegg too. Two bad panels in a row. Its really frustrating. Plus I order an AUO panel, and receive a SHARP. The replacement panel market is a total mess. Very hard to find a reliable supplier.

 

@SUADE8880 Hi im currently thinking about upgrading the Screen in my Legion 5 to B156ZAN05.1 4k 120hz
Ive seen that you owned this panel - can you tell me how the experience with it is? (colors, brightness, gsync working? etc)

Also i know that Panel would require the Mainboard of the Legion to have a 40pin 4 lane edp connector. As i do not yet own the laptop ive searched for pictures of the mianboard in lenovos parts database and found this:

https://pasteboard.co/Jw4GCso.jpg

As im fairly new to this - could anyone confirm that this is indeed a 40pin slot?

 

There are 4 pairs of caps, so it should have a 4 lane eDP in there, or its a 2 lane, and USB for the web cam...

 

According to Lenovo the legion will ship with this display:

https://m.panelook.com/NV156FHM-NX1_BOE_15.6_LCM_overview_45539.html

which is a real crap display but still uses edp 4 lane 40pin.

I could assume that it would most likely work..

 

Then yes, the needed cable is already present.

 

Thank you!

 

@ eXspir3

I went through the 4K upgrade as posted earlier while not this particular display researched the same size panels extensively. The problem I ran into was for a reasonable price no one had 120hz 4K's in stock.

https://www.panelook.com/modelcompare.php?ids=42501,43684,36194,40964,40776,39623,45287,39913

Take a look at those models and check for availability and specific replacement as many sellers will send you another model in its place. Confirm the exact model you decide on before submitting an order to reduce delays when they present you with another model in the shipping invoice and needing to return it.

The N66 I went with is performing well. There are some quirks going from FHD to UHD though depending on the OS / HW but functionally it works well. I've noticed that Windows HWM.exe process tends to bloat at times in memory usage but that's resolved with a reboot after a few days of uptime. There's a huge difference in how things look though for the better when switching from a dull display. Response time with normal use is fine, 60hz isn't that bad compared to 120hz unless you're doing something that requires a faster refresh for FPS.

 

@Tech Junky

Thx, i have 2 particular options in mind:

Either im going to go the said b156Zan05 Route which i described before. If that doesnt work out im going for the fairly new NV156FHM-NY5 1080p 144hz 500nit 100% Adobe RGB Display.

In my dreams i would have a good 4k Display for content consumption that supports 120hz so when i want to game i can dial the ingame render back to 1080p and enjoy it at 120hz.
Thats why all the 60hz 4k options are not really viable for me.

I Actually found suppliers for the B156ZAN05.1 which sell it for 130€ which is fine with me as the NV156FHM-NY5 would also cost me around that.

 

Definitely not a one size fits all when it comes to preferences.....

I don't see the NY5 being sold anywhere for the most part... Suppliers you find on panelook can be difficult to deal with unless you're buying multiple panels. Again the sales results for NY5 would indicate a high probability of getting a substitute model when shipped. (been there, done that)

https://www.panelook.com/modelcompare.php?ids=38454,36617,40445,41166,45536 FHD 144hz models I looked at and could source.

 

I found a seller that sells the NY4 Panel and asked him in message for the NY5 and he says he does actually have it and just received the first batch.
Even provided me with a picture of the Panel.

But yeah maybe fraud i dont know

https://www.aliexpress.com/item/4001289879061.html

Otherwise the N4J does look good and is sourceable

 

A good clue is if you can find them on multiple sites and specific photos like ebay of the actual panel. I went through tons of sellers before going with kreplacement.com and was able to confirm the actual panel after submitting an order for the BZAN you're looking at. When I went to confirm the order via e-mail with them they didn't have the BZAN specific model and asked them based on the list of comparable panels I had researched for which ones they had on hand and went with the N66.

Put in the leg work now to prevent disappointment when it shows up as something different.

 

The B156ZAN05.1 is a beautiful display covering 100% Adobe RGB color spectrum with a brightness higher than most average displays to provide more than adequate outdoor usage. I loved it.

However, I could never get it to work on 120hz due to bandwidth issues that Nvidia Optimus can not provide channeling through integrated graphics. Keep it in mind that the only laptops that are able to do 4K 120hz(Alienware, Razer) comes with the mux switch.

From the looks of the mainboard on the Legion it looks to be a 40pin but it isn't 100% certain that the connector at the end of the cable to the display side is a matched. Just like the new Razer laptops the cable started out as a 40pin .5mm pitch to a 40pin .4mm pitch. You'll have to weigh that in too and you can't tell without looking at the cable.

 

Thx! @SUADE8880
I am positive that the cable should be 40pin on both ends as it is used comes with the NV156FHM-NX1 that is listed as edp 40pin 4 lanes. But i will wait for the notebook to arrive anyways so ill have a look!
Also regarding the MUX switch --> This basically means i can turn off Nvidia optimus bypassing the integrated graphics right?

I will get the Lenovo Legion 5 15ARH05H 82B1005EGE and while i found no information on this exact model there is a video online about the same notebook (Model 82B1000AUS) but with 1660ti instead of 2060 and better screen stating this functionality at minute 11:55:



If this all works out i will be as happy as one can be haha!

 

To add to that:

After researching i have found the Lenovo yoga Slim 7 sporting the Ryzen 7 4700u or Ryzen 7 4800u both support Displayoutput at 5120x2880 @ 60hz via USB-C just using the integrated Radeon Vega 7nm Graphics which is also used in the Ryzen 7 4800H of the Legion 5.
5120x2880 is 1,77 times as much pixel as 3840x2160. So Maybe it would even be possible to get 4k to work at 100hz (60*1,77 = 106) without disabling integrated graphics in the first place.

I am not sure by any means - its just what i found out browsing specsheets haha.

 

Just be careful that there are different variants of 40pin due to it's pin pitch. In this case however, the display listed to be the common .5mm pin pitch. So you should be fine.

Yes, the mux switch will give Nvidia complete control to the internal display.

 

Anybody tried sticking an upgraded LCD into a mid range Lenovo?
I have an Ideapad 5 15are05 15.6 with 30 pin EDP display that I am looking to upgrade.
Especially interested in bright low power/efficient displays.

 

https://www.panelook.com/N156HCE-GN1_Innolux_15.6_LCM_overview_41166.html

500nit FHD display, anybody know if it works with Lenovo (Ideapad)?

 

Figure out your current display with HWINFO64 and then compare the dimensions to make sure it will fit. Keep an eye on the voltages / pins to make sure they're compatible.

Alternatively check the model # of your PC for compatible upgrades when it was being sold.

 

Anyone can download from panelook the datasheet of the screen "B173HAN05.1" in pdf format and share here? Very hard find this information...

Thanks.

 

What exactly are you looking for? Most of the info is already provided on the page for the panel. Do some comparisons with other devices using google.

 

Need the pin assignment like this.

 

I would like to upgrade my precision 7540 to 4k. Does anyone know what the model number is for the cable I need?

 

Ah very disappointing day for me, got the screen, but first of all the PCB at the bottom is slightly wider than the PCB of the original screen (no idea there could be these kinds of differences).
This is critical, there is no way to fit the screen into the housing.
Then even worse, the tape slightly lifted on the right side of the display, I applied new electrical tape over it, aligned it very nicely, but I pressed it down slightly too hard and now there are lines through the display.... this sucks.

We go back to the original screen. An expensive experiment, and for me personally I am done upgrading screens on laptops, it is just too error prone.

 

Hello guys!
I have a Samsung QX511 and recently, when I turn it on, the screen shows a big black rectangle in the middle (occupying 1/3 of the entire screen). Only after some time the rectangle starts to flicker a lot and later it disappears, then the screen works perfectly. I tried to open the notebook to see if the cable was well plugged: it was. But I somehow worsened the problem: for some days the screen began working only on 1/3, the other 2/3 were black. I tried to change the lcd cable, since I was under the impression that it was the problem (moving the cable the screen worsened, instead unwiring and touching the screen didn't have any effect), but the problem remained the same. So now I assume it's a screen problem (what do you think?). I'm going to change the screen, but I'd like to upgrade it to a full hd. The current screen is a LTN156AT19-801, I've searched thorougly on the internet but I can't find a fullhd compatible. Is there any?
Thank you!

 

@ dreamscreen

https://www.panelook.com/LTN156AT19-801_Samsung_15.6_LCM_overview_18881.html - this shows your specs and sizing. Being a 15.6" it's possible to upgrade to FHD / UHD depending on the GPU / CPU capabilities.

Depending on if you want to keep the touch screen or not is going to be a factor as well. Touch Screen = $$$$ vs non-touch.

Being that it's LVDS and not eDP sort of limits some of the options but, it's possible.

359.3 × 222.45 - this is the sizing you're looking for for the physical panel

https://www.panelook.com/sizmodlist.php?st=E20&pl=&so_attr=&sizes[]=1560&st=E20&by=desc&page=18
This takes you to the sorted by size around the same size as your current panel. There's a model or two in a prior page but there are more 1080 options from this page forward.

https://www.panelook.com/NV156FHM-N4B_BOE_15.6_LCM_overview_34862.html 1080/144hz eDP
https://www.panelook.com/B156HW03 V0_AUO_15.6_LCM_overview_13461.html 1080/60hz LVDS

 

Thank you a lot @Tech Junky for your help!

Currently my notebook doesn't support touch screen so, although it would be useful, I don't mind not having it in the new screen.

I did look on this website but I didn't know it was so simple as just looking onto the size, awesome.
I've just searched throughout the list and it seems that very few have the same size though.

I don't understand why are you suggesting this one if my current screen is LVDS, would it be supported also eDP?

I've noticed that the Outline Size of this screen is 359.5(W)×223.8(H) ×4.1(D) mm
My current screen is slightly different ( 359.3(H)×222.45(V) ×4(D) mm), would it be ok anyway? Sorry my ignorance, I'm wondering if the screws would fit.
I've also noticed that Display colours would be 262K 60% NTSC, my current one instead supports 16.2M 45% NTSC. Is this a big inconvenience?

A part from those you suggested me, I've found only this other screen:
https://www.panelook.com/LTN156KT06-801_Samsung_15.6_LCM_overview_15662.html
Which is only 1600x900, but perhaps is this more compatible given it is a Samsung screen as my current one?

Thank you again!

 

So, you have an idea on pieces of this process but before you dig too deep I would start with figuring out what MOBO cable options you have if you're stuck with LVDS it's one scenario and if you're able to convert to eDP it's more options of FHD or even potentially UHD if that's something you're interested in. I personally said hell with FHD to FHD and bumped to UHD for about the same price when it was all said and done.

You have a mm or two tolerance in fitting these things. If it's off just slightly it will still fit. As to the eDP one it's possible that you can convert the signal through another cable or adapter depending on the laptop. For instance mine had a 30<>30 but the new screen was 30<>40 so I needed a different cable that would allow a 40 pin output to the new panel. Sometimes the OEM has ports for both LVDS / eDP and you simply need a cable swap but to confirm it you'll need to crack the case open and take a look at the board to see what your options are.

Colors are relative to what you'll be using it for and what your perception of them is. Going from a 262K to 16.2M will be dramatic in how things appear more vibrant than they currently do. If you look at my thread on my upgrade I took side by side photos before/after and you'll see the difference. http://forum.notebookreview.com/threads/nh58raq-np6855-screen-upgrade-experience.833976/

 

Hello,

i have a notebook DELL G3 17" 3779, this notebook mount a display with this specific:

Monitor Name: AU Optronics B173HAN01.3
Monitor Name (Manuf): B173HAN [DELL P/N: MWY7K]
Monitor Hardware ID: Monitor\AUO139D

This display have 30 pin, i want updated it to 120hz or more, the new display have 40pin, if you see my motherboard that have 40 pin connector (see photo), if i change cable and install display with 40 piu you think working good? who have tryed this?

 

@ GigilinE

If you can find a cable that is 40<>40 then it should work. The determining factor though is the channels the MOBO can provide will determine if the panel you're looking at will be supported or not. If the MOBO only supplies 2 channels a 4 channel panel wouldn't work.

Check the specs for the CPU/GPU to find out what it supports for resolution / refresh limits to not end up with a panel under performing due to HW limitations.

https://www.panelook.com/B173HAN01.3_AUO_17.3_LCM_parameter_33384.html (eDP 2 channel / 30 pin)

https://www.panelook.com/popularmodels.php?id=33384 - direct replacements

Going up from the replacements is possible per se you want to go from 262K colors to 16.7M colors just make sure the physical size matches or is very close and the pin pitch matches

 

My cpu is Intel(R) Core(TM) i7-8750H CPU @ 2.20GHz
1 gpu is : Intel UHD Graphics 630
2 gpu is: nVIDIA GeForce GTX 1060

my hardware can supports also 240hz, you think if i buy cable 40 to 40 and monitor 120/144hz working?

EDIT: sorry but why you have post 240k color?

 

With those specs and a new cable you should be fine.
I'm running a 9750H / GTX1650 and picked up a 4K that's working great.
Sometimes finding the cable can be an issue. If you can't find one check with kreplacement.com as they seem to be able to source them easily along with the panels.

Be aware of "compatible" shipments and specify / verify the specific panel being shipped vs another model that's comparable in their eyes when it comes to any seller. I had zeroed in on a specific model and got something totally different / returned it and then went with KR but ran into the swap issue again but had backup models in mind already and picked the next best option from specs / value.

 

i want see datasheet on panelook but it ask 800$ lol
you have a plan for see B173HAN01.3 and B173HAN01.6?
the first is 30 pin (my panel) and second is 40 pin, i want see if is compatible

 

They're essentially the same panel with different revisions being .3 and .6

https://www.panelook.com/modelcompare.php?ids=33384,35469

One is 30P and other is 40P
.3 is 2 Lane / .6 is 4 Lane
.3 is 262K / .6 is 16.7M
.6 will use slightly more power because of the higher refresh rate.

All you need is a cable that will output 40 pins instead of 30.

 

does anyone know which pins on a 40 pin eDP LCD panel are used for EDID? im trying to program a custom EDID directly to the panel, i have a TL866II+ programmer and i have a cable meant for programming the edid stored on the displays rom chip but its not detecting it so i think the cable may be junk. the cable im referring to is below, would it be easier for me to just direct connect to the appropriate pins and the dump/write/verify?

 

For most 40-pin eDPs it is 34, 35 and one of the V+s and grounds. In this panel (on the right) those are labeled ' LCD_VCC' and ' LCD_GND':


Note that ' LED Ground', ' LED Power Supply', ' BKLT_GND' and ' BKLT_PWR' and suchlike designate pins specifically for the backlight power circuit and run on much higher voltages, about ~19V vs. 3.3V for the control circuit (barring a few 3D panels that use 5V). Of course, you don't want to connect to these pins to power the puny eeprom.

Either way, the above is probably correct for your panel as well, but can't hurt to verify with the panel specification sheet (Google or Panelook). Once you have verified which pins you actually need then check whether these are populated on your cable (peel back the yellow wrapper). If they're not then simply desolder some of the other wires and reconnect them, similar to what this user has done in a similar pinch.

If, however, they are populated then blame the programmer. There's tons and tons of different small I2C chips and only the most fancy of programmers can recognise the majority of them (price-category $500+) and without identifying the chip the programmer won't know what settings to use to write to it. You can always guess though and simply select one of the common models. Atmel AT24C is pretty standard.

 

thank you, i've spent many hours looking for what you just linked me to. i actually peeled the cover off the plug earlier suspecting it was wired incorrectly, the TL866 was giving a pin error, ignoring it only read blank. the plug only has 4 wires soldered which i could easily re-solder once i know which pins are which, going by the alienware thread you linked and his plug setup am i right to assume this is the pin order thats staggered left/right/left in order all the way to 40?




as for the panel B173HAN04.4 i think i have the spec sheet in a pdf that im now feeling dumb for not even thinking of looking there

 

Yes, that alternate left/right is correct. So you have a cable that is correctly wired to connect to an LVDS panel's edid eeprom; 4, 6, 7 and 10 (the 'first' of the grounds). Swap them and you have a connector that can wire to eDP instead.

There's no difference between the two in a technical sense; both are coaxial, it's just the protocol that is different and, hence, the pin-out. The coloured image above also shows neatly why eDP came about in the first place; both the LVDS and eDP setups use 40 pins, but with the same number of pins the former can do around 1920x1200 and the second 4096x2560, a factor of 4.5+ in raw data throughput (both are uncompressed).

 

the closest panel i could find a spec sheet on was B173HAN04.0 which is very similar, could you tell me which of these i should be working with

 

if im understanding this correctly (probably not) i would leave 4, 6, and 7 where they are but move 10 to 11 or 14? am i even close?
