Dreamcolor Display from HP ZBook 17 G2 into 8760w?

[loopster]

I've got a Dreamcolor display assembly from a parted out HP ZBook 17 G2 here.

Does anyone know whether the panel of this assembly can be integrated into a Elitebook 8760w as a straightforward swap?

The 8760w is running a M4000M.

I can't use the Dreamcolor display on the Zbook 17 with RTX3000 (or P3000 for that matter) as I understand, as the RTX3000 card needs

Hybrid graphics enabled in this model, which in turn would automatically be disabled with a DC display.

As far as I know the display connector is different. Other than that it should work.

The display is the same : 

LP173WF3-SLB3

also same as the ones ending in SBL1/SBL2/SBL4.

 

They use an eDP cable going to a converter that converts the 40 pin eDP int 50 pin LVDS that then breaks out into 2 cables that plug into the display.

 

Motherboard eDP connector -> (eDP cable) -> eDP to LVDS converter board -> (2x lcd cables) -> LCD 50 + 10 pin LVDS input

 

What is sure to work is get a non working dreamcolor motherboard cable + board + LCD cable from 8760w and use the lcd you salvaged from the zbook.

[JadeRover]

Actually the pinout of 8760w motherboard eDP connector is not compatible with zbook eDP Motherboard connector.

 

8760w has eDP and LVDS on the same connector wheras Zbook had only eDP on the connector.

 

pluggin zbook display cable on 8760w will short out LVDS and cause no boot at best and motherboard damage at worst.

 

Therefore you can only salvage the display from the Zbook 17 g2. You will need to source the DreamColor cables  + board made specifically for the 8760w.

I eventually put it in my second zbook 17 g1, which is currently running a crappy K610M. I'll probably drop the M4000M into this one,

and maybe sell the 8760w with k3100m inside.

Does the G1 support eDP on DP_D? You can drop an RTX 4000 or RTX 5000 from HP.

 

I dropped an RTX 5000 HP for the Dell precision M6700 eDP 120Hz edition.

[JadeRover]

I will soon get a G1/G2 not sure, blindly bought it for 40 euros, seller had no info at all.

 

On g1 schematic it has eDP on DP_D

 

One day when I have time I while write a complete guide on zbook 15/17 that have MXM slot (g1 -> g6)

[loopster]

I have no idea what that means :-).

I actually have a rtx3000 in my primary zbook 17.

 

I think it's Adlink

[JadeRover]

Uhhh, that not an acual picture right ?

 

We were talking about the pinout of the MXM connector that links up the GPUs display outputs on 4 different channels : A, B, C and D

 

Usually eDP from the GPU is located on channel D called DP_D

 

But for it to work the laptop must wire the eDP port to DP_D  of the GPU !

 

The confusion is that some zbooks : Zbook 15 g1 + g2 + g3 and zbook 17 g3 have it wired to DP_C meaning no output on the internal screen

That is an actual picture of my RTX3000 from the ebay listing I got it from, with its heatsink mounted ofc.

Was advertised as "NVIDIA Embedded MXM GPU Module with NVIDIA® Quadro® Embedded RTX3000 Mobile".

Won it for 120 sth. €.

Hello. This GPU doesn't have backlight pins set. So even if your laptop supports eDP on DP_D, your screen will stay black.

 

There is a dirt cheap RTX 3000 for 99€ on ebay, it's the HP variant with the backlight pins.

[loopster]

Yeah, and I got my running just fine, thanks 😉 My machine is a zbook 17. The RTX3000 displays through the integrated GPU. 

That's why I have to keep hybrid graphics enabled in bios. Otherwise it will create a black screen.

And that's the reason why the RTX3000 can't be used in combination with a dreamcolor screen, as the DC will automatically disable the igpu.

I got the HP RTX 3000 to work in DC with the Dell M6700.

Great, dunno know whether HP RTX3000 would run in the 17 G1 though with a 3rd party DC.

The thing is, the standard, non-DC Zbook uses an LVDS screen, and also the DC is LVDS I believe.

I don't know how this works exactly, but apparently the igpu puts out the video signal through the display cable,

which connects onto this board, and it is then converted to LVDS via this board below the screen.

 

HP for ZBook 17 G1, 17 G2, LVDS Board (PN: 741282-001, LS-9374P) - 2630138

 

The ZBook DC screen converts edp to LVDS too with an internal controller board behind the panel.

 

Dunno why, it's just a weird design to me.

 

Edit: apparently it would run:

That is the correct, Zbook 17 g1 uses a mux switch between dGPU and iGPU that goes to the eDP connector on the motherboard. Then that eDP signal is converted to LVDS and fed to the panel, they probably did this as 17.3 inch eDP panels were rare in 2013, they used off the shelf LVDS ones instead.

 

HOWEVER, iGPU has only 2 lanes of eDP (you can see that on the schematic) and the dGPU has the full 4.

 

When you have a DC screen it needs 4 lanes of eDP, all other stock screens require only 2. So with a stock screen BIOS will give you option for Hybrid graphics enable/disable.

 

When DC screen is plugged in, BIOS sees this and immediately disables hybrid graphic option and forces display through dGPU = no display if you don't have a dGPU installer or the dGPU you installed has no eDP OR it has DP (display port) but wit no backligh control pins = Black screen.

 

HP RTX3000 does have eDP on the correct port, DP_D so this card should work on the zbook 17 g1. I will test this soon as I have HP RTX3000 andzbook 17 g2.

 

Also here is an even cheaper RTX3000 (close to France in Europe) : Nvidia Quadro RTX3000 6 Go GDDR6 N19E-Q1-KD-A1 (HP ZBOOK 17 G6) | eBay 90 euros

Thanks JadeRover for expanding in more precise detail. Of course I was aware of the MUX business when I wrote "don't know how this works exactly".

What I meant was that e.g. I am not aware of the lanes bottleneck. What I understood thus far is that the igpu in the zbook 17 G1/2 can't drive a 10-bit panel.

 

One rather curious thing I found with this RTX3000 version of mine (presumed as ADLINK as I mentioned, bought in 04/2025) is that you cannot switch on the laptop on the docking station with the lid closed and any display port or thunderbolt port output connected to an external screen, maybe also VGA, not sure atm. - no matter directly on the laptop, or on the dock - because this will cause the UEFI/Bios to lock up, or "fail to post" for a lack of a better expression.

It does post just fine however connected to dock and nothing connected, or when switching it on with external outputs connected and the lid open.

Probably some handshake going awry somewhere...
I think I could easily solve this be removing the lid switch magnet from the display bezel, but for the moment I am not too bothered by this

to actually test out this theory...

 

Edit: curiousity got the better of me, I checked and it works with lid closed and VGA only hooked up.
