    AMD Radeon RX 550 - 560 injected with Opencore macOS Big Sur

    I did, same odd results with the colors etc. I'm beginning to think the old dude on Dell forums was right about the channels being weird or whatever.. I'm picking up another box to try tomorrow that's a little more modern. I'll try these cards in it and see what happens. maybe they're fine and...

    AMD Radeon RX 550 - 560 injected with Opencore macOS Big Sur

    agreed, standardization is great. just the same, if I boot with both the rx and my old gt710 connected to the display, I can access the bios from the 710 and see the rx listed in video cards.... but if I boot with the rx connected to the display, this happens

    AMD Radeon RX 550 - 560 injected with Opencore macOS Big Sur

    I agree. but still, I keep finding "it won't work" in different forums. I can get into BIOS, but it's really hard to see anything ;-) I can't believe just how much conflicting information there is about running low profile rx550 in this old Dell. wow

    AMD Radeon RX 550 - 560 injected with Opencore macOS Big Sur

    this is odd... done folks from Dell forums says it's impossible to run rx cards on this platform, others say it works fine. I'm finding it hard to believe u have two bad cards. I mean, that's basically my luck but still.

    AMD Radeon RX 550 - 560 injected with Opencore macOS Big Sur

    I was hoping to find out why they're behaving exactly the same way, rectify the issue and use one of them in my editing rig. my understanding is that these cards are supposed to be plug n play easy upgrades.

    AMD Radeon RX 550 - 560 injected with Opencore macOS Big Sur

    lol agreed. I purchased 2 of these.... the first one intent on using for the hack, but Amazon said it was damaged/un deliverable... so I purchased a second, and they both arrived the same day, undamaged. both cards exhibit these patterns. I can't even see the bios , sigh, I think I might be...

    AMD Radeon RX 550 - 560 injected with Opencore macOS Big Sur

    I have the pink yestron rx550 4gb mentioned earlier. when I start the computer the only available resolution is 1080p, and no acceleration. I'm sure that I do not understand what needs to be done to access full memory and acceleration of this card. is it as simple as adding a boot argument...
