    Hello. Flex cable allows to activate the blacklight pins on the MXM slot to the eDP connector. Without the blacklight pins being on, the screen stays off. Black screen, no display, etc. With this mod, you can install it on the new RTX Ampère, Ada cards. All of the cards have DP or eDP on port DP_D, the signals are ok but the cards are lacking the blacklight pins. The manufacturers don't care about laptop users. Basically we are forcing the powering of the blacklight pins so the internal eDP display will work.

    Hello, thanks for replying. The sleep mode works when the lid is closed, the screen goes black then goes on when the lid is open. Power saving, needs testing, but it should work. For the brightness PWM control, as said, some motherboard have it integrated, some not. Yes, from now, I'm manufacturing 30 pcs of the solder-less mod, with the funds, I can make a v2 if people needs it. It'll be cheap too.

    When there's an iGPU + dGPU in a MXM system, it usually have a MUX switch between IGPU, dGPU and the LCD connector. I think when it's on iGPU, it'll disable everything that's related to internal display for the dGPU. Again, needs testing on this part. People who wants to use the newest non-OEM RTX GPUs, they don't really care about iGPU. They want dGPU performance 100% and display capabilities (internal and out). Some MXM laptops are lacking iGPUs capabilities too. My flex cable is version 1. Once more people will buy it and test it, I'll have some feedback and I can maybe make a version 2 with advanced PWM control? I heard some motherboard can't control the PWM. For example Clevo laptops have BRIGHTNESS_R and PANEL_PWM for the LCD connector. I assume it's connected to the motherboard for the brightness control.

    Yes, you can put a manual potentiometer on the pin 27, for PWM lol. Yes when the laptop is in sleep mode, it just offs the power, depending on the laptop. The Clevo P570WM doesn't have a MUX switch for the LCD conn (eDP) I got confused for these points here: So you didn't test the GTX 1060 MXM on the laptop yet with the backlight mod? Because you said the vbios of the 1060 has HDMI for DP_C. Because I know the P3000 MXM has the backlight pads enabled and eDP on D.

    Hello. Nice. So you got your MXM GPU with a basic DP out (not eDP) on DP_C to display on your eDP screen? And it worked like that? Does your laptop have a resistor or a PWM transistor on the motherboard? It's usually called BRIGHTNESS_R on Clevo. Could you remind me again what's the brand of your GTX 1060M? Zotac, right? Is it made for a laptop or for embedded use only? (Desktop, external output only). So you ended up using the P3000? Rather than the 1060M? You can maybe find a vbios that can allow DP_C for DP? Yes the backlight mod works for these cards since for no reasons they lack it... It's 3.3V power to the 3 pins. We're sending power to the 3 pins. By looking at the MXM slot diagrams, you see that these 3 pins are going the LCD connector at the end and NOT TO THE MXM CARD ITSELF!! You can also buy an RTX 4060/4070 from ZRT/X-VSION and have full eDP support. And I also said this before you comment now: There were 2 ways to bring "eDP support" Buy an RTX 3000/4000/5000 from HP, they have DP on all ports even on C. Or do the backlight mod by soldering. Edit: I found a vbios for GTX 1060 for the MSI GT72VR: https://www.techpowerup.com/vgabios/191865/191865

    I know why it doesn't display on the internal screen, the card is made for desktop use only, like the X-VSION and Aetina cards. That's why you still have some output on an external display. If you're lucky enough, your card may lack a DP_D on your vbios? Try and flash a HP ZBOOK G6 T2000 one and see how it behaves ? If it doesn't work, then your backlight pins aren't enabled on the PCB of the card and you need the flex cable mod for the backlight or... You can do the mod by soldering on the MXM slot pins. Hey there, not this attitude with me, okay? I'm trying to help this person and trying to get the newest RTX MXM to work in the laptops.

    Hello again. You're telling me, an RTX Turing card with eDP on port D worked in your 2011 eDP laptop?? It means you can use an RTX 4070 MXM to work with your eDP display using my incoming flex cable mod for backlight enable. Yes Aetina cards lack the backlight pins so no display. Although they have DP on DP_D. A new vbios won't help the Aetina cards to obtain eDP support, it's hardware related.
  8. SuperMG
    Did you try the RTX 3000/4000/5000 from HP too? You can find cheap 3000 ones but I don't know if it'll fit or not. You said you can output thru HDMI, correct? What about DP?
  9. SuperMG
    Yeah I know that. But will it display in the bios too? I was more curious on this. Just sad the R3 bios is limited. The M6600 has UEFI correct? I think so, because someone managed to get an RTX Turing to display on the eDP screen.
  10. SuperMG
    What card it is? From HP or from Aetina/Adlink? HP has eDP support on port D
  11. SuperMG
    Wait, you have a M17X R3 eDP correct? I saw your laptop's MXM slot diagram, you can do the soldered version of the backlight mod! It means you can make your RTX 3080 MXM work with your R3 screen! I need to see if it'll work on this laptop because of the mux switch...
  12. SuperMG
    I would rather change. Look at the Clevo X7200, there's probably a whitelist for the GPU on the master slot, because the GTX 700 and above won't work. The Zbook G2 and G3 have the eDP on DP_C. I don't even know if there are any Pascal Vbios who use eDP on DP_C... But he can try the Quadro RTX Turing from HP because they all have DP on every ports and even DP_C Although, If he really want to use his GTX 1060M... I know one only way to convert "eDP/DP" DP_D to DP_C...

    Hello. For the BIOS mod, I mean it depends on your laptop because you have Optimus, it's an LVDS based system and it's an old Alienware afterall. For the eDP laptops: For our use case, we need to power the BACKLIGHT pins because the modern cards are lacking it simply! The GPU core doesn't even power its own backlight pins and that's why the internal eDP screen isn't even displaying anything! After looking at a various of MXM slot diagrams (from multiple laptops), I see that the 23, 25 and 27 are "one-way signals", meaning it's only going to the display connector and not going back to the MXM GPU.

    @janepa If you have an eDP laptop (DP_D eDP) with a MXM slot, please try the mod by soldering pins 278/280 to pins 23,25 and 27 for the backlighting. You'll see that your 4090, 3070 and RTX 5000 will work with the main screen. Try it please.

    Hello. Do you know where the eDP is on the X-VSION 4080/4090? I see eDP port on NVIDIA's control panel but I don't get it. I don't get it on which port the EDP is? On port DP_E??? does that even make sense? Please let me know, X-VSION's datasheet shows eDP on DP_B... My flex cable is just to enable the backlight pins back so we can have a display at the end. Most Turing to Ada are lacking the pins. Most of them have DP and eDP on DP_D The picture I sent clearly shows how it works. I see no LVDS conversion. It just 3.3V to power the backlight pins, that's it.
