HP Elitebook 8570W - is it still good ? Hardware modifications

[Daedalus]

Going on @Vladka76 view of using the Clevo Cable +HP DC + etc etc.  And please correct me if im wrong,  I assume standard 30pin layout, data pins etc.  So no "magic" happens at the display panel as e.g LG panel exists in Dell, Clevo, etc there should be standardised (except for mounting points) the only change would be the DC board doing the converting. could we not use a "other" brand solution? one thats more available than the "unobtainium" DC board? probably overthinking it here. 

I agree with the view of no need for 4K screen etc, but does that simplify it?

Thanks, but that wasn't exactly my view. 🙂

It seems you've misunderstood the idea.
She was to use only a modified cable between the motherboard and display, without a converter board at all. Re-read the latest replies from DevilAnGeL, the author of the "Ultimate 8770W yet?" thread. You even wrote there earlier.
I've read that DELL workstations also use a similar converter board (with a newer microprocessor). I can't say how compatible it is with HP.

Yes, dell m6600 and dell m6700 DC models have that DC conveter board that transforms the incoming eDP to 50 pin LVDS + 10 pin power cable used by the DC LCD.

 

The HP zbook 17 g1, g2 and 15 g1 that have the DC screen option also use such converter boards.

 

Keep in mind that for all the models stated the converter board looks something like this :

 

So if you get the DC cables for your model you see that it connects to your board in a non standard eDP format = can't use that cable to connect to a standard eDP panel conenctor.

 

Also the zbook 17 g1 and g2 all have this converted board as they all have LVDS displays and the motherboard outputs eDP. Not sure why HP chose this approach, probably because eDP lcds were rare in 2013-2014.

 

so zbook 17 g1/g2 with 900p to 1080p screes have this board if you want a sure way to get your hands on one.

And yes I get your idea, since the motherboard outputs eDP signals (4 lanes of eDP) but it terminates in an unusable connector. The only solution is to DIY / get made a custom cable that connects to the eDP connector on the motherboard and then directly to the eDP display, bypassing the DC board that would create an unusable signal.

 

4 lanes of eDP is on part with modern laptops, you can connect 4K dislays or 1080p >120Hz displays as well. Worth looking into as the only custom part needed is a custom eDP cable, the LCD can be an off the shelf 40 pin eDP display.

No problem @Vladka76 happy to be wrong 😉 just enquiring if that option had been investigated. 

 

Thanks @JadeRover that was kinda where my head was at with using standardized units for Display then we remove the intermediate board (which seems to be very difficult to obtain) 4K screen would be lovely but may overtax the HW in our 8570w's as previously called out. Would deffo buy the cable once we manage to get them built. 

 

Yeah never got a response from Devilangel on my query, he did an awesome build, TaoBao was a nightmare to navigate.
