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.
