The problem that I am currently experiencing is that the internal display is not functioning the way it should. The internal screen becomes partially fragmented after boot or black without injection kext made with Hackintool. Although the internal monitor is not functioning correctly, when I connect an external monitor (with FHD resolution) during/before boot It becomes fully functioning. If I connect it after boot then the screen will become less fragmented (will only fragment when there is a lot of change on the screen) and only fully functioning with mirror display option enabled. Here is a link to my repo with the current OpenCore setup. Here is the kernel log. DSDT dump DSDT.zip
I have a fully working E7440 laptop with Mojave, but I have one issue when I try to use my 4K monitor Samsung U28E590. I enabled HiDPI and installed RDM in order to select resolutions higher than 1920x1080, however it doesn't matter what resolution I choose over that 1920x1080 I never get the real resolution but a blurry fake one. I tried with my monitor native resolution (3840x2160) and many others with no luck. It looks like OSX is just faking the resolution and keeps just sending 1920x1080. I connected my laptop to monitor using a HDMI cable. Does anyone had experience using a 4K monitor with an E7440 laptop? Is it possible to use a retina resolution with this setting?
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.
