This one.  I don't think anything else is needed.

It worked. Thank you.

Hey guys.

 

So, I ended up getting a wx7100 and a new edp panel, but I need some help about the panel.

I got the edp cable, but the connector to the panel is different. Searching online a bit, it seems

I have to use an interposer (P/N 75V7G) and a second cable (P/N 64HMY) like this

In forums they say that the interposer is an edp-to-lvds converter (?)

Is this correct or do I just have to use a converter on the edp cable? Am I missing something?

 

Thank you

嘿,伙计们。

 

所以，我最终得到了一个 wx7100 和一个新的 edp 面板，但我需要一些关于面板的帮助。

我得到了 edp 电缆，但面板的连接器不同。在网上搜索一下，似乎

我必须使用像这样的内插器 （P/N 75V7G） 和第二根电缆 （P/N 64HMY）

https://www.ebay.com/itm/203100779785?_skw=m6600+interposer&itmmeta=01JCRT9T9SYJEWB74ZRSNGJ0HV&hash=item2f49bff509:g:rxwAAOSwG9Jg1cT5&itmprp=enc%3AAQAJAAAA0HoV3kP08IDx%2BKZ9MfhVJKn8znPWuJelsCB1AonJIv0D1vocBGCP1PRhBGi5fBGMy77qleu2S3pexweeOyPOIkYTQ1nnhtwKC4%2BSMueM0Q%2BguQKkR8GUDOwwbk7OxzKDf7LIOTAM69y1uSnZB7jjA2LUnAJAjLJ0AMnnag2GxZVxPVZEI7utTLPhwyPvt6T0BTCM0zmAIvM8fF2YtewaZl78zYnStmvCuiSulkaIMmXldM%2BTZg1Fv5GrtWbjHqyIaahdkk11VpmUTb2%2BLavfSyY%3D|tkp%3ABk9SR_6kp5rmZA

在论坛中，他们说中介层是 edp 到 lvds 转换器 （？）

这是正确的还是我只需要在 edp 电缆上使用转换器？我是否遗漏了什么？

 

谢谢

You'll need to use 3D eDP cable
The motherboard of the M6700 has two video ports

The M6700 will automatically disable the iGPU when connected to the eDP screen

For Dell Precision M6700 3D Screen Cable DC02C002D00 6VCJW 06VCJW | eBay

[AndrewK2685]

Thank you. The cable you posted is the one I've originally got (P/N 6VCJW - from same seller!!)

but the connector to the panel is like top-down style, where as on my panel is the slide-in style.

Is this correct?

 

Thank you

Andreas

[AndrewK2685]

Hi again

 

So this is the connector from the cable that I need to go to the 40-pin eDP panel.

It looks like the same one going to the motherboard.

Any ideas how I can convert it for the standard 40-pin eDP panel?

-the auction for the cable stated it as P/N 6VCJW,

unless they sold me the wrong cable 🙂 

@GREYSTAR@Aaron44126@TheQuentincc is your eDP cable similar?

can you tell me where you got it from?

 

Thank you

Andreas

Hi guys, 

 

Just to start off I want to say I really appreciate all the messages on this forum, I always wanted a laptop with an mxm slot and my dream has recently come true when I got an m6700 for a very good price with a k3000m. This forum as well as the nbrchive.net has been very useful for my research on it and it is incredible that such knowledge still exists. 

 

Anyways, I've been really happy with the m6700 I got as it has the IPS 10bit color display + delta fans + dual heatsink. A real monster! Some fixes had to be made but all in all it's running perfectly. 

 

I do a bit of gaming but nothing fancy, some e-sports and older story based games (gta 4 + 5 as well as CoD). I overcloked the k3000m to 1ghz and that made a good difference, the games I play are playable at 1080p low settings but performance tends to dip sometimes, I would like the experience to be better.

I'm planning to upgrade the gpu, my budget is around 50 euros and this is where I need some advice :

 

I found a M2000m for 40 euros locally and I think it is a reasonable price for a ~960m equivalent, especially if I can sell the k3000m OC for around the same price (they sell for around 45 euros 2nd hand in France)

- Will the mxm A card be compatible with the mxm B cooler? 

- Since I have an edp display with no Optimus available, if the gpu is "unrecognized" will I get a black display (saw that as an issue for m4700) ?

 - an m3000m is available for 60 euros on AliExpress, is it worth going out and getting it as it is ~970m equivalent? 

 

Also on a side note I can't get the 10bit colors to work, when I select it in the Nvidia panel and hit apply, the screen flashes twice but then the setting gets reversed to 8 bit, I am on drivers 397. 

Thanks, 

[JadeRover]

Hellos Andreas, 

It looks like they sent you the wrong cable, I have a srgb cable (for the IPS display, basically the cable we have carries the 40 pin edp signal to an interposer board at the bottom of the display bezel, this interposer than converts the 40 pin edp into 50 pin lvds + power cable for the dream color IPS lvds display). The 2 ends of this cable are this horizontal connector that you show in your picture. 

The cable we have is in the first Pic (notice the RGB-MB sticker + yellow eDP sticker )  

 

The cable you need is this 2nd one (notice the 3D sticker + the yellow eDP sticker also) part number is 6VCJW, so the seller must have messed up

Finally the cable you don't want! This 3rd lvds one (notice the HD+/FHD sticker as well as the white lvds sticker near the motherboard connector) 

 

Good luck! 

[Aaron44126]

Eh, normally the "3D" cable is the one that you want, unless you are trying to put the original 10-bit IPS panel in.  The "3D" cable will work with other eDP panels as long as the panel connector is the same.  I used the "3D" cable and was able to hook it up to a 1080p 120Hz eDP display panel in the laptop.  I didn't end up keeping it because it was a glossy panel.

 

@JadeRover

I believe you can use a MXM-A board in there and it will fit but it has been a long time since I saw someone try that...  Can't remember if it was M6600 or M6700 or M6800.  You are right, though, if the system doesn't like the GPU card then you won't get any display at all.  Well, sometimes in cases like this you can get an external display to work even if the built-in laptop display will not.

 

GeForce 980M is probably the "easiest" good GPU upgrade to slap in this laptop, but it looks like that is a bit over your budget.

[JadeRover]

@Aaron44126

Okay thanks, and do you know of a way to make a non supported/unknown gpu work on the internal display and without optimus? Does it have something to do with the bios or vbios maybe? Seing as for some cards a special bios must be flashed.

 

I have a ch341a and I have dabbled in bios editing+flashing before so it wouldn't be an issue for me to do it again

[Aaron44126]

I was able to use Quadro M5000M with the internal display without Optimus (note: LVDS display). I think most first-gen Maxwell GPUs would work (Quadro MX000M, or any GeForce 900 series). M2200 is a second-gen Maxwell GPU and I don’t know if they made any VBIOS changes that would mess that up.

[AndrewK2685]

Hi @JadeRover

 

Thank you for your reply and the very comprehensive post about the screen cables.

Indeed they probably messed up. Also, I noticed that my cable was

different than @GREYSTAR ( DC02C002F00 instead of DC02C002D00)

even though it had the correct P/N... Anyway I ordered a new cable and will report back.

@Aaron44126yeah I also got it as "3D" supposedly, but they probably messed up..

 

Many thanks!
