Hi
@CaseySJ,
(Sorry, my English is poor. The following is Google Translate. I hope you can understand it.)
I encountered a problem when the
BIOS->IGPU->Enabled booted When loading the system to the 4/3 progress, the display will flash. Sometimes can enter Catalina, sometimes it will enter a
black screen.
This happens only after the computer is turned off and then on, Sometimes enter a black screen sometimes not, This problem is not only on CATALINA, but also on Mojave, I don’t understand why this happens.
I tried to solve the black screen problem and found 2 cases;
①: check
-v Boot Arguments flag can enter Catalina
②: When ① cannot be resolved,
BIOS->IGPU->Disabled can enter Catalina. After restarting BIOS:Enabled IGPU again i can still enter Catalina.
I think this problem is caused by LG UltaFine 5K?
Here's my spec:
Intel Core i9-9900K
GIGABYTE Z390 DESIGNARE
AREZ-STRIX-RXVEGA64-O8G-GAMING
Samsung 970 EVO SSD 1TB
Corsair LPX 16Gx2 3200 ddr4 * 2
LG UltaFine 5K(2019)
