Laptop Screen Upgrades

https://en.wikipedia.org/wiki/DisplayPort#Resolution_and_refresh_frequency_limits

It gets a bit murky at 1.2 vs 1.4 or 2.x.

You have a 50/50 shot at it working @ 4K vs 1080

 

I don't really understand.
DP 1.2 is HBR2 which give about 4.32 Gbit/s per lane.
So a 3 lane DP 1.2 should provide 12.96 Gbit/s and 4K @ 60Hz require 12.54 Gbit/s . Am I getting something wrong?

That being said, I can't seem the find the NE173QHM-NY2 anywhere.
So I am only left with the
B173ZAN05.0
or the
B173QTN01.5

These are pretty much all the displays I would want to put in my laptop:
https://www.panelook.com/modelsearc...ch_high=1740&ppi_low=140&sunlight_readable=-1

BTW, I will also need a 30pin to 40 pin eDP adapter, right?
https://www.aliexpress.com/w/wholesale-30pin-to-40pin.html

 

The easy answer would be if your laptop had a 4K option when it was for sale or not.

Otherwise you need to check the specs for the CPU / GPU to make sure 4K is possible and then confirm the eDP specs are wired for a 4K option or if they limited the traces to 2K or less in the service manual.

 

OK, I understand.
1. The laptop doesn't have Optimus, so it's only the GPU here that matters, right now I have a 860M GPU, which supports DP 1.2 and 4K @ 60Hz.
2. The processor is a 4940MX.
3. The laptop was offered with G-sync and 3D displays, but never had anything more than 1080p @ 120Hz.

I guess, my best bet is the B173QTN01.5
I will need the eDP 30 pin to 40 pin converter, right?

 

You should be able to source a 40-pin cable and avoid any converters. Converter's are just another point of failure to deal with.

Look in the service manual and dig up the cable options as even a bump to 144hz will result in a different cable. G-sync / 3D tends to lean towards a 4K ability and you might already have a 40 pin cable in place unless you got the base screen being sold at the time.

The only thing that sticks out as a potential issue is the iGPU associated with the 4940MX might not tolerate 4K. It says it will but, that's a bit suspect as to which port supports it whether eDP or HDMI or DP.

I would gather your info and a couple of panel options and find a seller to source options from. From there you can decide on which panel you want to try out. I found it easier to find a seller that had both the panel and cable I needed in one transaction instead of having competing shipping times of arrival.

 

You do make a valid point. Well, I don't have the original eDP cable. But here is the original eDP cable for this model:
6-43-P1771-A10-K is 30Pin-30Pin eDP cable for CLEVO P177SM-A.
https://www.aliexpress.com/item/327...earchweb0_0,searchweb201602_,searchweb201603_
I have no idea what I need to buy.

 

https://repo.palkeo.com/clevo-mirror/P1xxSM/ (UN: repo/PW: repo)

You'll find a service manual here and potential PN's for the cable you'll need.

Should probably show up w/ EDP4K in the name if there's an option available.

 

You are right. But why does it say 40pin, when the connection is 30 pin?

It's definitely 30-pin:
https://www.aliexpress.com/item/32814650782.html

 

Because they're counterintuitive about labeling the cables. The MOBO side stays the same and the panel side varies to either 30/40 pins.

Whether or not A10-K will work on a 4K display is a different story. This is where you need to be a detective and look at the schematics and see what the EDP portion shows whether or not it mentions 4K is a clue. While we know the CPU/GPU support it the MOBO needs to as well.

Good news is the replacement cable is 40 pins and you won't need any adapters.

 

I am super confused, I counted 40 pins for the LCD header in these pictures:
https://www.aliexpress.com/item/32814650782.html

 

The MOBO side w/ white plastic is 30 PINS
The PANEL side is 40 PINS

It moves some of the wires to accommodate the panels with 40 pins.

 

I hope you are right cause I counted 30 pins here:
https://ae01.alicdn.com/kf/HTB1UHw5...o-P177SM-A-6-43-P1771-A10-K-20454-30p-SH1.jpg

 

The problem you run into with most of these sites is generic photos of the items.

[email protected] - e-mail these guys and ask them for confirmation, they can also bundle the shipment of both items to arrive at the same time and their prices are pretty good.

 

Hi everyone,

I have an old but still good Dell Vostro 3460 laptop. I like it, it is still useful except the display is low resolution and very poor quality. Can somebody please help me how could change the default screen to a FHD IPS screen?

Right now it has this (it’s the default): https://www.panelook.com/modeldetail.php?id=15316

Thanks

 

From here you get the size

320.4 × 205.1 / LVDS / 40 pins

How much effort do you want to put into it?

Looking @ LVDS / 1080 there isn't any options. It's going to require switching to eDP and that's up to your laptop if it ever came with an eDP model variant which would give a part # for a different cable which opens the options to better colors / resolution.

Good news is if you can do eDP there's not too many options to sift through that meet your 1080/more than 262K colors.

https://www.panelook.com/modelcompa...975,23640,25359,27367,32776,33405,34048,43329

Stripping out the discontinued models and inferior color coverage you're left with 4 options.... 2 @ edp 4 lane (40 pin) and 2 @ edp 2 lane (30 pin) depending on what your MOBO will support with a different cable.

https://www.panelook.com/modelcompare.php?ids=15316,25359,34048,18919,23640

 

Thank you.
There is no such thing as LVDS to EDP converter?
I am not sure how to find out what my MOBO can support.

 

https://www.sevarg.net/2019/02/10/thinkpad-t430s-ips-screen-upgrade/

Apparently there is. Looks like it would double the cost but, there's a way to do it. Since this isn't a native swap 1:1 it's hard to say if you'll get 2 or 4 lane support out of an adapter and your current panel supports a single lane in comparison as well as providing about 1/3 of the power. In theory it should work if you're willing to take the risk and deal with potentially having to swap more than 1 panel to find the right combination that works.

 

Thanks. But I’ve seen these on Aliexpress and I wrote to a seller and they told me these are only for Thinkpads. I am not sure if that is true, but its a bit pricey to try. Do you think they can only work with the specific Thinkpad models? Could they be programmed to work with them only?

 

I haven't looked into them prior to your question and it's always a risk that things like that won't work.

I'm sure though if they make / sell one for thinkpads they probably have generic ones for everything else. You just have to do your homework and find one that will work if that's the path you want to take.

 

Lonising, are you sure the NY1 has PWM? Some Chinese users say the opposite (NY1 using DC Dimming). The best way to confirm would be with a Super Slow Motion (Some smartphones have 240Hz Slow Motion), does the screen causes headaches or eyestrain?

 

It was definitely PWM.

At any rate, I have reinstalled the original AUO display, because the BOE NY1 display I purchased stopped working (and the seller is refusing to respond nor give me a refund). I hardly use the built-in display anyway, now that I've got my LG 27GL83A monitor.

 

Okay, gonna skip NY1 then. Thank You!

 

Between these two panels, which one do you think is better?
https://www.panelook.com/modelcompare.php?ids=20840,24679

Edit:
From Notebookcheck:
https://nqbzyw.db.files.1drv.com/y4...WTQLr5Hrc9xHvuXmwiq-ZZdLTPIL2Q/bla.png?psid=1

 

Hello, could someone help me choose between these two panels for my legion 5 with amd?
NV156FHM-N4J
NV156FHM-NY5
I have these doubts: The N4j has hdr400 and the ny5 only says hdr, will there be differences in quality? Besides the ny5 has a wide range of colors, but will I see oversaturated windows even if I set a srgb color profile? Thanks a lot

 

https://www.panelook.com/modelcompare.php?ids=41414,46515 << compares both side by side

N4J has a haze applied for antiglare
NY5 has better color coverage spectrum
N4J has a slightly better viewing angle by 4 degrees in each direction

If it were my decision I would go with NY5 since it doesn't have the haze applied and fuller colors available.

 

Maybe it's not a gaming laptop, but I think it may be relevant to anyone interested in small machines, I've just been able to modify HP X360 Pavilion 11u from stock 1366x768 screen to N116HAN5.0 Full HD screen. Improvement is very much visible, the biggest problem with this machine is the fact that the display is glued to the digitizer. It's compatible out of the box, however in my case I've had to reinstall system, since it started BSODing all of a sudden, however since it works fine after the reinstall and SSD swap I believe it's just a coincidence (it's been lying on my workbench disassembled for quite a while). Anyway, hope this makes someone's day happier

 

Thank you very much, I think I also prefer the ny5 but I am afraid that with so much color coverage, windows and srgb content it will look too oversaturated. Anyone know about it?

 

http://forum.notebookreview.com/threads/nh58raq-np6855-screen-upgrade-experience.833976/ This is my upgrade with a side by side screen comparison.

 

Hello everyone,

I just purchased Acer Aspire 5 A515-44-R02Y laptop
It has AU Optronics B156HAN02.1 LCD inside (based on EDID info).

So I have a crazy and risky idea to swap it with 100% sRGB LCD.

One guy on another forum asked Acer support about similar laptop A515-44G compatible LCDs, they gave him this list:
KL.15603.004 CPO LCD 15.6(FHD AG 85) LM156LFCL07 STNBS
KL.15603.004 LED LCD Panel Panda 15.6'W FHD None Glare LM156LFCL07 LF 220nit 25ms 1000:1 (eDP, value IPS, narrow border)
KL.15605.062 LED LCD Panel AUO 15.6'W FHD None Glare B156HAN02.1 H/W:4B LF 250nit 25ms 700:1 (eDP, value IPS, narrow border)
KL.15608.043 LED LCD Panel LPL 15.6'W FHD None Glare LP156WFC-SPD5 LF 250nit 25ms 700:1 (eDP, Value IPS,narrow, 3.2mm max)
KL.1560C.009 LED LCD Panel SHARP 15.6'W FHD None Glare LQ156M1JW01 LF 300nit 25ms 1000:1 (eDP, IPS, narrow, 3.2t)

When I upgraded RAM, WiFi and installed HDD on the laptop I noticed that it has 40 pin eDP connector (photo attached).
But it looks like LCD itself has 30 pin eDP (2 lanes).
Is it common practice for laptop manufacturers?

LCD is glued which is not a great thing of course:
https://laptopmedia.com/us/highlights/inside-acer-aspire-5-a515-44g-disassembly-and-upgrade-options/



At Panellook I see such options:
https://www.panelook.com/modelsearc...high=220&depth_typ_low=3.0&depth_typ_high=3.2

https://www.panelook.com/modelcompa...518,41242,35110,34288,39913,44377,46771,42488

It's weird that this one is not in the list: https://www.panelook.com/LQ156M1JW01_Sharp_15.6_LCM_overview_45233.html
Do you think it will be possible to find, purchase and install LCDs that I got in Panellook search?
How critical is the several mm difference in Outline Dimension Vertical measure?
Thank you so much in advance!

 

@tbter When looking at things you want to match the "outline dim. 350.66(H)×216.15(V) ×3.2(D) mm"

As to the pinning when you look up the panels by outline size you can compare them side by side for differences like pins / pin pitch to make the right decision.

To decipher the 30p vs 40p that's something you have to dig into to the support manual to determine what your laptop will ultimately support.

My upgrade for instance never came with a 4K option but did list an eDP cable part # for a 40p output to the panel and I was able to use that and upgrade to 4K w/o any issues.
-- btw the mobo side is a 30p socket that snaps to the mobo

If you figure out the cable issue you can get the right screen options.

 

@tbter You can use a panel with the resolution of 1920x1080 and the refresh rate of 60Hz in this model, 144Hz panels and 3840x2160 panels are not supported, so avoid buying a panel with these specs, there are 3 unsuitable panels in your comparison.

 

Why do you say they're incompatible? Is it just because they're not listed as an OEM option? I went 4K w/o an OEM option and it works just fine. What matters are the HW specs of the CPU/GPU and then fitting the panels with the appropriate cabling.

 

I think you have done the upgrade on a gaming laptop with higher specs, his model has an integrated graphics and it's an everyday laptop, if he manages to successfully install a 4k panel in that model it will be awesome

 

I think when it comes down to it you look at the CPU/i/GPU and figure out what it can handle. Most relatively recent components don't have an issue driving a 4K panel. I wouldn't consider a GTX1650 high spec in comparison to "gaming laptops" you see posted around here.

https://www.aliexpress.com/i/1005001266204971.html -- looking at the model referenced by @ tbter

AMD Ryzen 7 4700U - https://www.amd.com/en/products/apu/amd-ryzen-7-4700u
https://laptoping.com/gpus/product/amd-radeon-graphics-of-ryzen-7-4700u/ - shows about 1/2 the benchmark speed of my GTX 1650

I wouldn't say it's impossible to put a 4K into this particular chassis as it's not spec'd to be a gaming laptop anyway. Display performance shouldn't be an issue when it comes down to it. Making sure the panel / pins / pitch lineup will be the issue to sort out as this model didn't come with a 4K option in the lineup.

 

Thank you guys,
Ordered this one: https://www.panelook.com/N156HCG-EN1_Innolux_15.6_LCM_overview_45792.html
Will see how it goes.
It has 5 mm smaller Outline Vertical.
But I hope that it won't be a problem.
Hope to get and install this panel in couple of days.
Will keep you posted.

 

I installed a B173QTN01.4 panel (1440p, 120Hz) into a Clevo P870TM1-G successfully. Lost G-Sync.

Here is the thread: LINK

 

I have successfully updated the Legion 5 display with the NV156FHM-NY5 panel. Only one problem: panelook says it has freesync but the AMD program says it's incompatible, does anyone know how to fix it?

 

Purge the drivers and reinstall would be my first step w/ DDU

If that doesn't work then it's going to be more complex firmware or EDID reprogram if it's actually an included feature of the panel.

 

Has anyone had any experience with the 15.6" 120Hz UHD LCD's? I just bought a used MSI Alpha 15 A3DDK with a 144Hz FHD LCD, but would prefer to have a 4k display.

My understanding is that the 144Hz 1080p LCD's typically use 4 HBR2 lanes, so a 60Hz UHD display should be compatible (unless I'm missing something), but I'm unsure about the 120Hz UHD displays.

The dedicated GPU is a Radeon RX 5500M which should support Displayport 1.4 (and therefore presumably HBR3?), but I can't find any information on whether the LCD is connected directly to the 5500M or to the integrated Radeon Vega 10 Graphics on the 3750H CPU and whether the integrated graphics support HBR3 or not.

I also don't know whether those panels are physically compatible with the chassis.

Has anyone had any experience with these? I'd also be interested in the 60Hz UHD OLED panels, but again I'm unsure if they'd be compatible or not.

My final question (for now) is whether there'd be any issues with a triple UHD display setup consisting of (hopefully) the 120Hz UHD LCD, a UHD TV connected via HDMI 2.0 and a cheap UHD monitor connected via displayport.

Thanks in advance for any help.

 

To be honest, for many of these questions the only answer is through trial and error. You don't want to know how many displays I went through throughout the years.

 

I was worried that would be the case, but I've never replaced an LCD with a different model before and I'm hoping someone can point out any obvious mistakes, incompatibilities or omissions before I buy something unsuitable. Sorry for the overly long posts.

It feels like there should be some software tool that can tell me at least whether the LCD is internally connected directly to the dedicated graphics or through the integrated graphics. I can't seem to find that though. It also feels like there should be information on the supported DP version of the integrated graphics, but again I can't find that.

The current panel is a B156HAN08.0. According to Panelook, this has overall dimensions of 350.66(W)×216.15(H)x3.05(Typ)-3.2(Max)(D) mm, is connected through a 40pin connector with a pitch of 0.5mm and has an input voltage of 3.3-3.6V.

Aliexpress lists the NE156QUM-NZ3 for around 116 EUR. According to Panelook, the overall dimensions are 350.66(W)×216.12(H)x2.6(Max)(D) mm, is also connected through a 40pin connector with a pitch of 0.5mm and has an input voltage of 3.3V.

There are also listings for the B156ZAN05.0 for around 129 EUR. Again according to Panelook, the overall dimensions are 350.66(W)×216.45(H)x2.6(Max)(D) mm, is also connected through a 40pin connector with a pitch of 0.5mm and has an input voltage of 3.3V.

Finally there's a listing for the ATNA56WR08-0 OLED panel for around 198 EUR. I can't seem to find the overall dimensions, but it's also listed as being connected through a 40pin connector with a pitch of 0.5mm and an input voltage of 3.3V.

The B156ZAN05.0 has a Mini LED backlight as opposed to the NE156QUM-NZ3 which has a WLED backlight, so for that reason alone I'm leaning towards the B156ZAN05.0 even if it costs a bit more. My understanding though was the Mini LED was more useful for HDR content, and the B156ZAN05.0 seems to only be an 8 bit panel (and therefore presumably incapable of receiving HDR signals?). Has anyone had experience with these Mini LED panels? Are they worth paying a bit more for?

There's a post on reddit from someone that connected the B156ZAN05.0 through a 30 pin cable instead of 40, and was able to run it at 2160p 60Hz (but not 120Hz), presumably with 2 HBR3 lanes. Hopefully even if the motherboard doesn't support HBR3 I can run it with 4 HBR2 lanes and switch between 2160p 60Hz and 1080p 120Hz.

I think I'd prefer a 120Hz LCD to a 60Hz OLED, but that's a tempting option too.

EDIT: I'm also concerned about the connector placement. On the current B156HAN08.0 ( https://www.panelook.com/images/202004/1587630241064495.jpg ) it seems to be in a slightly different position than on the B156ZAN05.0 ( https://www.panelook.com/images/202003/1584946703527332.jpg ) or the NE156QUM-NZ3 ( https://www.panelook.com/images/202102/1613805920068585.jpg ) and with the ATNA56WR08-0 ( https://www.panelook.com/images/202007/1595855983330247.jpg ) I can't even tell if it's the same connector.

EDIT2: Fixed small mistake with HBR version.

 

Open the case but, it's not like a desktop where a dedicated GPU has its own ports to connect to.

These are the newest tech for panels and should provide better images / longevity due to the newer tech.

Some MOBO's only have a 30 pin to attach to and the other end facing the panel can be modified to 40 pin output. My laptop had a 2nd cable option that went 30<>40 vs the original being 30<>30. The swap out cost $15 for the different cable and works fine. My model never came with a 4K panel but looking through the components CPU/GPU it spec'd out as supporting it so I went for it.

It's all preference but, OLED will not last as long as LCD or mini-LED due to burn in issues and the OLED consumes more battery when not connected to AC.

Normally not an issue but, if it is you can get an extension cable if perhaps the port move from one side to the other.

I spent days evaluating different models / options and it's a bit of a process nailing down what you want and whether it's worth it from the $$$ stand point.

As to ordering confirm they will ship the exact model you want as many send out substitutes that aren't to the same spec and when it shows up you end up with typically an inferior product. (been there, done that)

I was looking at the 120HZ 4K as well but, no one had it in stock and the ones that did were way over priced and went w/ a 60hz. The improvement over the panel it shipped with was night and day anyway and the 120hz wouldn't really make a difference in normal day to day use. It depends more on what your plans for use are if it's gaming then FHD / 1440 is a better option. If you want real estate to spread things out or tile windows then 4K works well.

 

@krp

Make it a bit easier to compare things side by side - https://panelook.com/modelcompare.php?ids=34288,43684,45892,47315, 40776

I added my upgrade to the end of the list of comparisons and it's the same size as what you're looking at which means you could use my upgrade experience for comparisons of different models as well.

 

Thanks. After reading through your post, I realised that I had been looking at panel voltage, not backlight voltage. That's listed as 7V minimum for the current panel, and 9V minimum for the B156ZAN05.0 that I had been leaning towards. I'm guessing that's not a risk I should take? Can you also tell me what you mean by 25% haze as opposed to true matte?

I guess that changes my options to the NE156QUM-NZ3 if I want UHD 120Hz, the ATNA56WR08-0 for OLED UHD HDR or something like the one you chose for LCD UHD HDR.

 

The Haze is the anti-glare coating they apply to a glossy screen to dull the reflections.

https://panelook.com/modelcompare.php?ids=34288,43684,45892,47315,40776

I went with the N66 for a few reasons - 4K / low power / # of colors / brightness / contrast

The Voltages are just something to keep an eye on but as long as the MOBO can supply at least those numbers the panel would work. Less V's though means better battery life as you draw less power. Older panels draw more power due to design efficiencies that have improved since they were first released.

As long as the physical measurements line up and the pin count line up that's 1/2 the battle. Picking the specs is the hard part and how much you're will to throw at it in price.

 

Is there any way to find out what voltages my motherboard supports? I'm a bit concerned about that post you linked to where someone seemingly fried their motherboard from connecting an LCD with the wrong backlight voltage.

 

Thanks for all the help so far. The current 144Hz FHD screen is the only >60Hz LCD I've had, so I'm going to try using it for a few weeks to see if I actually notice any difference before deciding whether to go for a 60Hz UHD LCD, a 120Hz UHD LCD or a 60Hz UHD OLED

 

For anyone else looking, 'Advanced display settings' in Windows shows you which GPU every display is connected to. In my case the Internal Display is 'Connected to AMD Radeon(TM) RX Vega 10 Graphics' while the external displays are 'Connected to Radeon RX 5500M'. My understanding is that the iGPU only handles the internal display and gets help from the dedicated GPU for more demanding applications like gaming on the internal display, whereas the dedicated GPU handles everything to do with the external displays.

Unfortunately, that doesn't really help me. I've installed the full AMD Radeon bloatware package as well, and there under Settings->Display->Display Specs it shows that 'Current Link Settings' are '5.4 Gbps x 4' which corresponds to HBR2 (and a 40-pin cable, presumably). Unfortunately I'd need HBR3 (8.1 Gbps x4) for the 120Hz UHD LCD. Maybe the RX Vega 10 Graphics support that, but I can't find any source of information on that.

 

https://www.amd.com/en/products/graphics/amd-radeon-rx-5500m

Looking at the Vega 10 portion seems AMD has went the route of iGPU similar to Intel w/ UHD series graphics. So, looking at the "APU" i.e. iGPU depends on the processor as to which specs the APU is providing. Looking at the 5500M specs though you're fine up to 4K.

 

I already have a 4k tv and a 4k monitor connected externally through the 5500M, that's not the issue. I'm also pretty sure that the RX Vega 10 supports HBR2 (and therefore presumably 60Hz 4k), since that seems to be how the 144Hz 1080 panel is currently connected. I'm trying to figure out whether the RX Vega 10 supports HBR3 for 120Hz 4k.
