Damn, I'm getting random reboots while rendering video with Adobe Media Encoder. I also have a GTX1070, but AFAIK GPU doesn't do any real work, when encoding in h264. The temps are usually below 60degC, which is nowhere near CPU limit. Very weird. Update: Wrong CPU Type + Undervolting is...

Hacking along with this build. Sort of hit a brick wall with the Intel HD630 4K Glitches. This is probably due to DVMT-Prealloc, but I'm curious whether there are any ways around it. As mentioned before, it's not a deal-breaker, just an annoyance, but I would be eternally at peace if I find a...

Hey guys, any luck with Backlight Control on the GTX1070 built-in G-SYNC panel? I've managed to get the screen recognized as Built-in, and the slider is there (even the keyboard shortcuts work) However neither the slider nor the hotkeys have any effect on the screen brightness. Maybe...

Update! I had a bit of time off work, decided to improve my quality of life by fixing the Thunderbolt problem I have been having (hot-swapping). I've reached a point I set out to, only with the help of the people that posted in this forum earlier, so I feel like I owe it them to make this post...

Hey @xeoneux! Well, the answer is yes, but no. I got USB-C video working, but 4K was too much for it. It's down to DVMT-prealloc size, which is just too small. I experienced video glitches and random reboots when graphics got a bit more complex (like rapidly moving a window). The display, on...

Hi, Thanks. I've tried that already. Doing that results in an instant reboot/crash/black screen (depending on what I do with the tablet)

Tried going back to IntelGraphicsFixup, ended up with the same glitching problem. The only thing left to do is increase DVMT-prealloc size in BIOS which I can't do. So, a dead-end.

Correction: If I bootup with monitor on, it doesn't glitch, however the computer restarts abruptly when doing a graphics intensive task. If I'm not able to change the DVMT-prealloc, would you suggest going back to IntelGraphicsFixup? I'd lose 4K, but at least I'd be able to use the Tablet.

I'm not going to mess with BIOS integrity. There isn't an easily accessible setting in BIOS that I can change... So I suppose I will have to live with it. I guess this could be marked as solved, as I get 4K video through my USB-C. Thanks again for your help!

I'm still working on it... Can't seem to find a reason for the glitch. There's only a handful of programs that get glitchy (complex 3d objects get glitchy as well). The glitches stay if I change the resolution. However, I found that if the display is ON during boot-up, the glitches don't appear...

Yes, it works, but keeps glitching. Also, the iGPU does not appear in system report. Either way, I've patched the connector-type to DP, but no improvements. I need to tidy up my install as I've been chipping away parts of it due to switching to WhateverGreen. Hence the problem in the kextcache...

I've attached both variants of the properties. Note that I cannot "turn on" the Wacom display using the 591b ig-platform-id as it results in an abrupt restart. Thanks again.

Okay, I've reconfigured my system to use WhateverGreen and Lilu. With enable-hdmi20 (and -cdfon) I'm able to get 4K output though my thunderbolt port! But I have to use an incorrect AAPL,ig-platform-id. 0x59120000 works (Only with MacBookPro14,3 (which is the closest to my system)) The IGPU...

Interesting, I thought that only applied to HDMI ports. Okay, I've tried to avoid using WhateverGreen for as long as possible as it breaks my bootup for some reason, but it seems that I must use it anyway. Let's see what I can do about it. Appologies for the IOREG with no screen, I seem to...

I have definitely pushed forward. I now have Nvidia doing the displaying on the Built-in monitor and the Display Port Monitor, AND IntelGPU displaying on the tablet connected via Thunderbolt port. (I can also hot-plug thunderbolt port stuff) (But sometimes I still get "too much power" message on...

Thank you for your reply, RehabMan I did try the usual route of enabling the IGPU, which, I assume, I succeeded. (I used WhateverGreen in conjuction to However, the problem is that the I need the Discreet GPU to display the graphics, while IGPU to work only for the USB-C connection (as...

Hello all. I have a very interesting issue and I need someone help me reach a possible solution. So I have managed to get my hack running to the point I am pretty much satisfied. The only problematic point left is the Thunderbolt type-c plug. Still can't figure out how to enable hotswaping...
