Hello @JohnSRQ,

Couple quick comments about HDMI connection to TV:
  • Modes such as Deep Color, HDR, and Wide Color must be turned off in the TV.
  • Some TVs have special instructions for connecting to a PC or gaming console. Please check the TV's documentation.

Using GPU HDMI I now manage to get a consistent signal on the flat screen now but only if I downgrade the image: I must set to 50 Hz and a lower resolution than the screen's default, in other words, standard definition .

My TV does not have Deep color or HDR, etc. It’s not 4K. I’ve checked and rechecked TV settings and manual. Like I say, it worked with previous build.

I feel like something isn’t set right, the same TV worked with same cable etc with my previous build which had much less powerful GPU. In system report is see Radeon RX 5500 XT 8 GB which is correct. How do I check to make sure the right driver is being loaded. The system report shows AMDRadeonX6000.kext loaded.

Anything I can check in IORegistry? Do I need to modify SSDT?

Thanks

Another option is to download and try SwitchResX.

Hi all

Can you please suggest a supported nic card 10GB both SPF+ or RJ45 that I could use?

Trying to do a direct connection to a 10GB port on file server (freenas) for higher transfer speeds

Thank you

I accidentally updated to 10.15.7 without updating OpenCore. I can no longer boot from hard drive, and my serials were erased. How do I fix?

Simply boot from your Bootable Backup disk that was made in Step 13 of Post #1 (specifically, connect the bootable backup disk then press F12 at the BIOS Splash Screen and select that disk from the list). After booting from that disk, use Carbon Copy Cloner to clone the backup disk back to the main SSD. Also mount EFI partitions of both drives and copy EFI folder from backup disk to main disk.

Please note that if your main SSD is actually okay, but you believe that only the OpenCore EFI folder is bad, then it's only necessary to copy the EFI folder from the EFI partition of the bootable backup disk. It's not necessary in this case to clone the backup disk to the main disk.
