Your laptop probably does DP_C output. Because I know that HP Quadro Pascal and Turing have all the eDP port set to DP_C. You need to find a vbios or a way to modify the eDP port to DP_C. Your 4090 either doesn't have eDP or has it but it's on the DP_D port.

I asked the manufacturer of the RTX 4070 MXM if they can switch the DP_D to DP_C output for the eDP compatibility. The manufacturer ignored me but did give me a tracking number for the incoming RTX 4090 115W I bought. If all of the 4060/4070 from X-VISION have eDP on DP_C it would be a big win for most of 2012-2018 laptops. We can have the 4060/4070 display in the internal screen!

Yes but Aetina doesn't have eDP support due to its VBIOS yes?

The display is from the Intel UHD and the renderer is the 4090 correct? Could you please also provide us the ZRT 4090 VBIOS please? Thank you.

Hello here's a group about Clevo P570WM compatibility list of MXM Graphics cards. The Clevo P570WM has two MXM slots. This laptop doesn't have integrated graphics, so no Optimus. Both MXM slots could provide PCIe Gen 3 speeds. This laptop has two motherboard versions: one that's for LVDS display 60Hz and one that's for eDP display 120Hz (V2.2 of the board). LVDS display boards can allow from GTX 400M Fermi all the way up to GTX 900M Maxwell but "Beta Sample/Engineering Sample" of Pascal VBIOS cards could work. eDP display boards can allow from GTX 600M Kepler to RTX Turing with brightness control at 120Hz. eDP display should be on port DP_C. Yes you heard it, RTX Turing works on this laptop with HP or Dell VBIOS. I tested with an RTX 3000, so other models from the same era should work (T1000, T2000, RTX 4000/5000). I didn't test Aetina, GETEC, ADlink Turing cards. I heard some don't even have eDP. What about Ampere and Ada MXM cards? It depends on the manufacturer and the VBIOS the card has. I can guarantee you that anything above Pascal won't work on LVDS displays. Same goes for cards that don't support eDP out on DP_C. I tested RTX 4070 MXM from X-VISION. It has eDP but only for the DP_D out. The manufacturer could possibly rewrite the VBIOS thru readable code and make the eDP to DP_C out. Meanwhile, DP and HDMI external outputs were working. But there's a workaround to make newer cards to work on Clevo P570WM while using the laptop's display. Use the master MXM slot as display. LVDS: Maxwell for master (best is GTX 980 or M5000M) eDP: Pascal or Turing for master (best is Quadro P5200 or Quadro RTX 5000) Use the secondary MXM slot as renderer. RTX 3060/3070/3080/4060/4070/4080/4090 for slave. I would recommend a card that's below 115W TDP because the original heatsink won't handle anything above the mentioned TDP. You need to do some workarounds in the Windows registry to make the slave's card the main DirectX and OpenGL card. The drivers should be at the same version. There are no FPS limits unlike on Alienware M18X R2/M17X R4 with the Intel HD that's capping everything at 60FPS max. For AMD cards, I haven't tested anything on the first master slot. I only tested an HD 8970M which worked on eDP.

Hello. I tested an RTX 3000 on my laptop and it worked. any RTX 3000 with HP/Dell bios works on eDP. So it means RTX 4000 and 5000 will work for my laptop. Is the RTX 3000 HP DP_C? Correct? The 4070 from X-VISION is DP_D. I got no display from it other than external outputs.

Hello, how do I know which is DP_C, DP_D?? The 4080 from X-VISION has eDP port declared but the seller says card doesn't do eDP.

Does someone have different 4070/4080/4090 VBIOS from like Aetina, ZRT?

Bios from ZRT? I'll receive the 4090 X-Vsion in a week. Are the DP_ from the VBIOS or are they hardcoded to the hardware ?

4070 is probably DP_D. What about the HP 8770W/8570W/Zbook G2 at? Are they DP_C too? I tried the 4080 too on my Clevo eDP, it didn't work for the internal display. On Alienware it does the 8 beeps

The 4070 I bought had also "eDP" written but it didn't work as said. On Alienware eDP and Clevo eDP. Would probably have the same results on Dreamcolor displays.

I'll not run it on Alienware. It'll go on Clevo p570, had no issues with 4080 115W power limited thru Nvidia inspector. The 4090 I got is a 115W one and doesn't have any capacitors lying around the x-bracket's zone. The 4070 I have, doesn't have eDP. It doesn't work on M17X R4 and Clevo P570wm eDP displays. 4080/4090 have the connector present on the Nvidia control panel but they don't have eDP.

Actually you have the first commercial version. I'll get the newest one without the x-bracket issue. Look at their new pictures now

I already bought from them a 4090 115W. Thanks for mentioning the X-BRACKET layout. I told them to give me the right one!

I'll ask x-vision for a custom bracket. Surely they have one, how did they test the GPU then? I want to pass all the heatpipes on the bottom of the CPU socket. (front view of the motherboard). Then Connect the heatpipes to the copper plate of the GPU2.
