M4800: not all are built the same (LVDS vs. eDP)


Recommended Posts

Hi guy!

 

Today i will talk about M4800.

 

Multi-Prototype:

May be all people don't know or don't care: "M4800 have 2 prototype of Motherboard" <--- it's the dead point that i discovery. 

 

Prototype 1: Dell Motherboard LVDS TRPM M4800 (full lucky):

+ use LVDS for internal Display (with max resolusion is Full HD)

+ can disable Switch Graphics (run only Quadro/Firepro) full performance, full external port.

+ if don't want Quardo/Firepro can run with optimus.

---> Replace Wifi + upgrade WWAN/mSata SSD ----> a monster of Workstation Mobile.

 

Prototype 2: Dell Motherboard EDP TRPM M4800:

+ use eDP for internal Display - eDP full HD / HD+ (not so lucky):

+ can not disable Switch Graphics. (black screen)

+ cannot export sigal to HDMI/DP/VGA

+ internal Display use intelHD 4600

+ Quadro/Firepro can use for any Software use Cuda/OpenGL for render/editor. (can disable Quadro/Firepro by DSDT).

---> Replace wifi + upgrade WWAN/mSata SSD ----> a monstar too ( but smaller than Prototype 1).

 

i'm not sure but may be Prototype 3 for 4K display use DP (don't have intelHD4600):

+ use DP for internal Display - that may be good if can inject monitor by some key or may be bad because don't have intelHD 4600

 

How check:

Use Ubuntu Live:

command is: Xrandr

 

<image updating>

 

 

Check VBIOS

<image updating>

 

Use Aida64 report

<image updating>

 

Prototype 1: install OSX very very easy.

Prototype 2 (is my M4800): very very easy with enable Switch Graphics. (not talk about it).

let's talking about disbale Switch Graphics! - big issuse with black screen.

 

.... updating......

 

next day i will update more. ...

 

more image, more infomation, and more about same hardware (M6800, Zbook 15 Dream Color, 8570w Dream Corlor, ROG 120Hz 3D screen ... ).

 

thanks for watching.

I have the 4K screen,  can get both HDMI / and external DP port to work using the Nvidia Web Drivers, but never the internal display.  I want to tackle this by trying to modify the NVDA configuration but cannot get the correct configuration.
