cool, was considering M5000M vs 980M upgrade for my machine hence the ask as i have LVDS. i mean id love a 10 series, but without DC (or equivalent) i'm stuck. 

Hello. I do have a few Maxwell MXM if you want. GTX 970M and 980M. Compatible with LVDS and eDP. One is a Clevo and one is a Dell.

[Daedalus]

Cool will reach out to you via PM. 
has anyone found any links/suppliers for the cable to allow the Dreamcolour IPS screens to work with the mobo? I know guitarg was working on one.

Are you using the latest driver? And what about the brightness adjustment, is it stuck to the max or can you adjust it normally?

I am using driver 426.5 the brightness control works even with the shortcut keys fn+f9,fn+f10

I recently found something:
https://www.ebay.com/itm/145765636591
This cable theoretically (as it seems to me, may be wrong) connects the motherboard and the original display for the DreamColor on 8760w, 8770w - LP173WF3-SLBx ("x" may be 4, 3 or 2). All is perfect (S-IPS, matte, exotic 10-bit color depth), but connection type of this display is 50-pin LVDS. 😀 Moreover, he is relatively old and difficult to find in new condition.
The main disadvantage of this option is that installing this display and cable does not improve the laptop's compatibility with fundamentally newer video cards. A much more promising option would be an eDP 30-pin cable (for FHD displays), which respected @GuitarG is working on...

But the Quadro Pascal such as P5000 and P5200 will work on Dreamcolor. I got the RTX 3000 from HP to work with the Dreamcolor in PEG of the M6700 and the P3000 did display in PEG but ACPI error due to the VBIOS.

Nice find. Most of this forum will have a bidding war lol. Good to see they exist, I was trying to find one for my upgrade. I’d seen an IPS screen too but wasn’t sure if even this cable would work with it. Doesn’t this need an additional DC inverter board too?

However as you say @Vladka76 it won’t help us run the newest cards. I think RTX 5000 is the super best we can try with Dc.

Yes, all DELL's similar workstations have iGPU enabled and working - so they can work with newer cards even via LVDS interface (I've read about it, this was not my own experience; I've even heard that MXM 3060 (Ampere!) worked well with LVDS display). But our beloved HP EliteBook's don't have iGPU at all (newer ZBook's already have it)...
Yes, I've heard that in DELL's Pascal cards works only with Engineering (early) vBIOS, but Turing cards all works well.
Now I can only dream about RTX 3000 (standard MXM 3.0b) working in my 8770w... 😕

3060 is massively bottlenecked by Intel Optimus and the old mux switch. 3060 has also the weird 40W TDP bug on Haswell based systems that use Intel Optimus. 3060 works great on pure-eDP

I'm afraid just one cable won't be enough. You're right, a complete DC kit consists of a color depth converter board and two cables: an outgoing eDP cable from the mobo to the converter and a LVDS cable from the converter to the display. I tried searching for the complete kit but couldn't find anything. There are a lot of DC cables, by the way - will be no bidding war here. 😀
I also thought about buying such a cable to start creating my own experimental EDP cable.

I guess that the DELL M6700 (with eDP), but not M6800 -  is the best one for upgrading video cards?
Yes, I've heard that a discrete graphics card without an iGPU (without Optimus) is 15-20% faster. That's comforting — and it motivates to figure out how to help EliteBooks...

I got the RTX 4080 in pure-eDP to work on M6800, the only problem is the heatsink for the temps. I don't have any TDP bugs, it's full speed.

 

M6700 can do max RTX 5000 Turing. Everything new won't work on eDP, need to use LVDS for newer cards.... (HDMI out is full performance)

🤩 This is simply great!

It seems that it is better to buy M6700 with LVDS cable and display?

Have you ever upgraded our EliteBooks (8560-8570-8760-8770)? 😉

No I didn't. I only did Clevo and Dell.

 

eDP with newer cards could work in full UEFI but I don't know how to get full UEFI to work, that's why the newer RTX Ampère and Ada don't work.

 

I have a M6700 for sale, with LVDS and eDP 120Hz screen. And the custom RTX heatsink

If i recall correctly, HP elitebooks dont have the traces in CPU socket to run iGPU (intelHD) so its MXM or Bust....... which does suck. i think the newer 840's have it, but the 8570W doesnt.

At least you don't have Intel Optimus with an old mux switch

From an energy efficiency perspective, having Optimus is better than just DGPU, since it is still a laptop.

My idea is to buy eDP 30pin cable for Clevo and use original one from HP (or buy one cheaply to not destroy original one :P).
Simply, because then we solder only one side. Muuuuch easier to make it work. And less subject to noise problems.

Only real question is will it work with my RTX? As you know I already checked with K1000M and everythings works as intended. But it was so long time ago I don't remember.


And I checked videos I made when trying 4k cable, it worked too, but my bad was in using LVDS hp cable. 4K clevo cables would be a lot better (signal needs special treatment - traces length, noise supression, etc).

That's why on Chinese forum they said guy modified clevo cable for his 8770w

 

[Daedalus]

Yeah I saw that reading thru the other post, it makes sense now. 
would that negate the need for the dream colour board? Therefore a normal IPS screen maybe possible?

I can find these cables but the board is unobtainable

Will the M6700 DC board be compatible with your cable and screen?

[Daedalus]

That’s a valid question, not sure without researching pinout. Maybe something guitarg could confirm. 
its worth a try though as it might open options. However a dell screen might be a pain to fit to Hp hardware

This sounds quite logical and correct! 👍

Cheap dirt. AFAIK, about 15-20$. Even those 4K ones.

Very! In fact, one guy using here is right on this forum, too. Have you seen ultimate 8770w thread ? 

Though..

... now I remember there was reason he uses Radeon MXM 😕 And I hate that word. Compability (between vbios and LCD matrix). And I encountered that problem before, with Clevo.

I have a lot of free time on my hands (pun intented, you know, carpal tunnel ^^). Maybe I will think of something.

EDIT. Well, during writing I already got first idea. I need zbook 17 g6 original LCD to check. It should be 100% compatible with mine RTX, since it's same platform and even laptop model.
And even if it doesn't work, we still make step toward solution.
