ho un problema con un monitor Dell p2715q 4k, funziona bene a prima vista, ma quando lavoro su programmi piu' pesanti, ho qualche problemino , del tipo che su certe azioni risulta rallentato a livello grafico. Invece se ridimensionato il monitor alla risoluzione nativa (3840x2160), sembra che questo problema sparisca. In pratica ho problemi solo nelle dimensioni intermedie. sapete se si puo' fare qualcosa? Il problema credo sia dovuto al monitor e non alla scheda video, perche' su un monitor full hd non ho problemi di rallentamento.
Per ora sto usando solo Lilu e wahtervergreen , senza questi il monitor nemmeno si accende.
So I managed to do a vanilla install of 10.14 on my new machine.
I have 2 exact same displays hooked up to my ASUS STRIX RX470 8G.
Display 1: connected via HDMI
Display 2: connected via DVI to HDMI cable
Display #1 works perfectly fine, but display #2 has a really ugly pink/ magenta tint to it.
In Clover (in fact even in the first half of booting) the second display has the colors just right.
Then, my screen glitches/ flashes for a second
The display #1 continues to work properly, #2 turns pink.
The display sleep does not work correctly. Starting with Mac 10.12.4, the display sometimes does not wake up. The backlight works, there is no image, a black screen. Currently installed 10.14.1. All the same. If the display is sent to sleep, then sometimes it can wake up in a black screen with a working backlight. From the description, it is not difficult to guess that the display sometimes wakes up correctly and sometimes wakes up in a black screen. In the course of the experiments, I also saw that the display sometimes woke up and showed the boot screen (the Apple logo and progress bar), a second after that the desktop appeared. This behavior occurs only when the display wakes up on a black screen and then I close and open the laptop cover again, after which the boot screen sometimes appears for a second, but sometimes nothing appears, the system just hangs.
I hope I clearly described the symptoms of the problem.
The screenshot was taken after the experiment. I sent the display to sleep, then woke it up. He woke up in a black image with burning lights. Then I closed and opened the laptop bucket, pressed the space bar and waited a few seconds. After a few seconds, the boot screen with the Apple logo appeared and then the desktop appeared. Immediately made a screenshot.

I managed to boot into Mac OS Sierra with my Intel Core 2 Duo, Nvidia 9400 GT and 4 GB of Ram machine, got internet and sound working, but the issue appears when I boot with Nvidia Web Driver. I get these acid colours, but Graphics Acceleration is working fine. I tried to inject EDID from my display, but no results as well. Would be really grateful if someone could provide some help. Thank you!
