I followed the OC guide, and installed Catalina 10.15.5 on my PC.
The installation went very well. Most parts also work well after I login to the desktop except the following
Each time I tried to log back into the desktop from sleep, I would get a black screen very shortly after I entered the desktop.
And black screen will last from a few seconds to a few minutes, no exact lasting time.
Keyboards and mouse are still working during black screen, I can see the operations after the monitor works again.
It connects LG monitor via DP port and I tried to modified the dp version between 1.2 and 1.4, got the same issue.
Attached my entire OC folder, I'm so appreciated if someone could help me check it out, or tell me which part I should focus on.
Thanks in advance!

Trying to get Hardware Acceleration working on my Hackintosh (HEVC Support) however I am such a noob, OpenCore is very new to me and would love some support.
I have included screenshots and the EFI that is currently working on my System, I have USB 2 & 3.0 all working, however, the only thing I can fault is my GPU not being hardware acceleration enabled.
Final Cut Pro X - Recognises GPU
VideoProc - Doesn't recognise anything.
(I am running the latest version of OpenCore 0.5.9)
Things I've tried: I tried following the post https://www.tonymacx86.com/threads/catalina-10-15-2-update-lost-hevc-h265-acceleration.288563/ - No Luck
I have also tried: https://forums.macrumors.com/threads/activate-amd-hardware-acceleration.2180095/page-53?post=28255048#post-28255048 - No luck either!
My friend online tells me I shouldn't need such Kext as he has the same build as me but when I load his EFI on my system it boots with no USB 2 or 3.0 (I'm keeping his EFI off here as I've uploaded mine.)
Please note: I appreciate all (any) pieces of advice and please do bear in mind that I am a noob and may need whatever you say simplifying as I can get easily confused.
This guide is a work in progress and will be updated as I refine the installation.
This is my first "modern" hack supporting UEFI and my first hack using Clover "on-the-fly" patches. My previous hacks
Laptop: Thinkpad T61 / Nvidia NVS 140m
Laptop: Dell Latitude E6410 / Nvidia G3100m
Desktop: Gigabyte G31 / GeForce 9600
Desktop: Biostar TH55HD / Sapphire Pulse RX580 (Google "Catalina Biostar TH55HD" and look for user name deeveedee)
are all perfectly running Catalina and I patched them all "manually" - all DSDT patches applied with MaciSL with virtually no Clover on-the-fly patching and all booted Legacy Clover. This UEFI hack was MUCH easier and took about 20 hours vs. a combined hundreds of hours for the old hacks. I wanted a hack that was a little more future proof and I think this is it. I hope you enjoy this as much as I am enjoying it. It is a perfect MacMini8,1.
My system specs
HP EliteDesk 800 G4 Mini (I7-8700T / UHD 630 / Q370 Chipset / 32GB DDR4 RAM)
3 x DP Ports (connected to monitors using DP -> DVI adapters)
6 x USB 3.1
1 x USB Type-C 3.1
2 x NVMe SSD (M.2 PCIe x4 2280/2230 combo ports)
1 x SATA6 SSD
1 x Intel Ethernet RJ-45
Conexant CX20632 Audio Codec
SMBIOS MacModel MacMini 8,1
Unsupported M.2 PCIe x1 2230 Intel Wi-Fi (currently disabled in BIOS). I may replace this with Brcm, but am using only Ethernet (IntelMausi) for now.

Known Issues and their solutions
(Solved. Cycle power on the new display) A new display may not be detected if the new display is plugged into an unused display port while the HP EliteDesk 800 G4 Mini is sleeping. Solution is to cycle power on the new display after waking the EliteDesk 800 G4 Mini. Cycling display power on the newly added display causes displays to be re-detected.
(Solved. Problem resolves itself after a few boot cycles) After applying the Catalina 10.15.5.02 supplemental update, Catalina booted to a single display. After a few boot cycles, multi-display operation was restored to normal.
(Solved and included in the attached EliteDesk.zip archive) Unable to upgrade from 10.15.4 to 10.15.5 when using IntelMausiEthernet.kext. Solution is to switch to IntelMausi.kext (Rev 1.0.2 here).
(Solved and included in the attached EliteDesk.zip archive) Some USB devices were not recognized. My SSDT-UIAC.aml was incomplete and did not specify all required USB port types (missing SSxx ports). The attached EliteDesk.zip archive includes this fix.
(Reported this as a possible Clover issue - no solution yet) Clover boot loader may default to Recovery volume after a normal shutdown. Work-around is to select your normal macOS volume. This may only happen when Clover is configured to boot LastBootedVolume and may be "fixable" by explicitly setting a boot volume (haven't tested this).
(No longer observed) At least one display blanks (sleeps) when plugging / unplugging USB device (observed in front USB 3.1 ports). Display wakes immediately on keyboard and mouse activity, so this is a minor issue but may be indicative of another issue.
(Solved - this is a BIOS setting and requires no macOS changes) Safari has problems loading insanelymac web pages after sleep / wake. I suspect that the problem is with the embedded video on the pages. Also observed video problem in AppStore after sleep/wake. Console: VideoDecodersUnavailable. Solution is to enable Intel ME in BIOS.
(Solved and included in the attached EliteDesk.zip archive) Display does not fully wake after resuming from sleep (needs an extra mouse or keyboard stimulus to fully wake). Solution is to change boot arg darkwake=0 to darkwake=2. Other values of darkwake may work as well, but this is the first I tried and it worked.
(Solved and included in the attached EliteDesk.zip archive) -disablegfxfirmware boot arg is not required with WEG. I inadvertently left this boot arg after I encountered an endless gfx firmware update boot loop while working on my FB patching. This boot arg is no longer necessary after completing FB patching with WEG.
(Solved and included in the attached EliteDesk.zip archive): Sometimes, CMOS time is lost on shutdown or restart. Solution is to enable Clover's Apple RTC fix in config.plist.
(Solved and included in the attached EliteDesk.zip archive) headphone jack doesn't work. Solution is to change HDEF layout-id to 28.
(Solved and included in the attached EliteDesk.zip archive) System freezes on wake from sleep because of a kernel panic related to hda-gfx (my system does not have HDMI and my DP->DVI adapters do not drive monitor speakers). Solution is to add No-hda-gfx property to HDEF as described here. This property is recognized as a Lilu flag and prevents loading hda-gfx.
(Solved and included in the attached EliteDesk.zip archive) Device (PMCR) is not defined. Solution is a SSDT that "injects" the missing device.
(Solved and included in the attached archive) eficheck is loaded (not sure why this is bad, but may be a privacy issue - see here). Solution is to add updated EFICheckDisabler kext that include Q370 chipset. See here.
