w651sf screen upgrade

Hello , i just want to upgrade my screen to full hd from 1366x768 ( silly one ).
Anyone can give me some tips about it , links as well for which screen and cables should i buy.
@Prema
Thanks.

 

Which panel do you have now? Use HWiNFO or MonInfo to find out, if you don't know already.

If the W651SF is similar to the W650SF then there's four out-of-the-box options; hd or fhd eDP and hd or fhd LVDS. According to the service manual there are different motherboard versions to accommodate them, but some Clevo models have dual connectors (regardless of what the esm claims), which means you could use either screen type, (rovided you have the correct cable, of course). Also, if you happen to have an eDP screen right now then you wouldn't need a different cable since it is already 2-lane, whereas the LVDS panels use either a 1-channel or a 2-channel cable.

Since you have to open it up in order to swap the screen anyway, best check the motherboard's connector(s) first. If you happen to have a dual connector type then it allows far more screen options to choose from.

 

Hey, thanks for reply.
My laptop has LG Display LP156WH3-TLT1 panel so which panel should i buy and do i need anything else?

 

That's an LVDS, so you'll have a single-channel LVDS cable right now. That means buying a dual-channel to make fhd work, apart from the screen itself; ask for part nr. '6-43-W65E1-021-L'. Acceptable price is around $25-30. If they charge you much more than that then simply ask other resellers or after-market spare parts sellers.

As for the panel; there's plenty to choose from. Question is whether you care about quality (colours, blacks etc.) or whether simply 1080p is sufficient? If you want a good panel, then you'll have to buy a used item in order to get what you ask for (most sellers will ship 'compatible', which is a lottery). Also, would glossy be ok? Within the same model lcd the glossy version will trump the matte on all aspects, apart from reflections, of course.

 

Is this what i need to buy ? > https://www.alibaba.com/product-detail/RoHS-Compliant-LCD-Cable-Factory-40_60587062221.html
Sorry i'm not experienced on changing laptop screens. If u give me some example links would be better for me so i can find same in my country or can buy on aliexpress.
I mostly care about panel , needs to be matte.

 

Nice cable. You could diy your own with that, but don't think that is up your alley just yet. Thing is that the LVDS cable is pretty much interchangeable on the lcd side, but the motherboard end is manufacturer- and model-dependent. Each pin has to be matched to the correct output and there's no standardisation here, requiring model-specific cables (jacking up the prices, unfortunately).

Ask your reseller for the part nr. listed above or inquire with others. There's an extensive list of European resellers and some US/Canadian resellers participate in these forums, so you can ask these directly via a pm.

For a panel swap guide search YouTube or iFixit; it's all pretty much the same thing. Something for a different Clevo model is fine, but so are those of other brands. They all use similar designs, the only possibly tricky ones being touchscreen models.

Here's a list of matching panels (and possible reviews):

• B156HTN02.1
• LP156WF4-SLB1
• LP156WF4-SLB2
• LP156WF4-SLB3
• LP156WF4-SLB5
• LP156WF4-SLB6
• LP156WF4-SLB7
• LP156WF4-SLBA
• N156HGE-LA1

Sadly, not a lot to go on. Only a few of them have been measured and the ones that have aren't something to get excited about. All are better than the hd you have now, so there's that at least. The glossies would've been better and there are some other mattes, but they have the connector at the opposite side, so the cable won't be able to reach them.

The last one on the list is the stock fhd panel that came with the W65xSF, but it is pretty dreadful, all things considered. My bet would be on the only AUO, the B156HTN02.1. (how-to video, too). There's no reviews either, but AUO makes some nice panels and at least it'll be possible to run it at higher refresh rates whereas none of the LGs will be capable of that.

Wherever you order; ask for the specific model. Otherwise there's a good chance you'll receive a compatible alternative, which could mean that appalling LA1 ...

 

I think it will be better if i open back case of my laptop and screen than take photo of them after that i think you can tell me which cable i need to buy excatly.
I think any panel which have 40 pin and 15.6 inch will be compatible with my laptop and I just need to get correct cable , right ?

 

Hi T456 i just need a quick help from you.

Is possible this cable works? Edp connecter to screen 40pin lvds board?

 

That depends; with 'LVDS board' do you mean a converter board or an LVDS panel? If you want to hook up an LVDS display to an eDP socket then no, it would not work (without using an active adapter). But a display cable is just a bunch of copper wires, so you could, in theory, use an 'LVDS' cable to do eDP-mb -> eDP display or 'eDP' cable for LVDS-mb -> LVDS display. This would be a lot of work though, since the pins will be wired differently, requiring extensive modding (research, soldering iron and steady hands). Also, most eDP connectors are now 0.4mm pitch whereas LVDS is usually 0.5mm and mixing those will cause shorting.

No. You have to take into account eDP vs. LVDS, pin-configuration, pin-pitch and location of the connector (left vs. right).

The panel I've listed will work, but you're of course free to try a different panel (my list is not inclusive). Just be aware that using an eDP type and/or wrong pin-configuration will fry the new panel (and occasionally the cable or laptop's motherboard).

 

I have a v3-571g acer, some models have FHD others HD, the ones that have FH, hava a edp board connection and a edp screen, others that have HD screen is LVDS-LVDS like mine.

In my case i have a board with a LVDS slot and a 20pin cable.



What i m asking is: "Can i use that cable (that i show you in the image before) that connects 40pin LVDS to my board, and connects edp to the screen?"

The cable is make for my model laptop, is for v3-571g acer laptop.

Sorry my english and thank you.

 

Ah, in that case; no. Well ... apart from the soldering and such, but that takes practice, time and previous experience. The pin-out of the eDP cable will not play nice with your new fhd lvds panel.

Search for different, same-era Acer models that came with fhd LVDS panels and try to source their display cables. However, even if the mb connector is 40-pin and thus sufficient for 2-channel lvds that does not mean the pins on the 2nd channel will be powered (you need 2-channel lvds for all panels 900p and more). Though chances are they are live, since it is cheaper to make a generic board, but you make certain by measuring all pins with a multimeter.

If you cannot obtain a 2-channel LVDS cable from another Acer system, but provided the V3-571G uses a 2-channel mb then you could also buy a diy cable which are easier to mod. But then you'd have to know which pin on the mb connector does what, requiring a schematic of your motherboard:
