A1222+ and Radeon RX550 - works in boot menu but not AmigaOs 4.1

[kubatyszko]

Hi there,
I have a brand new A1222+ (Topaz), installed OS4.1 and it’s working fine with the built in GPU.
When I install my Radeon RX550 (the same type as ready-made A1222+ have but different manufacturer). it works in the boot menu, I also see the OS startup progress bar with drivers loading etc,
But it never shows the AmigaOS 4.1 logo.
I’m wondering there’s a driver I need to activate or some other issue?

I didn’t. I just installed it and I get the same behavior.
Is there a “wrong ” way to install it?
I did the full novice install (because it was too much work confirming everything).

I just did a full wipe and reinstall of the OS and the Enhancer - same situation.
I checked, and the RadeonRX.chip line is in my Kicklayout, which seems to be the only requirement for the driver to work. I only have one section in the Kicklayout.
Could this have anything to do with the fact that my Radeon only has DisplayPort outputs ?

Thanks

My monitor can do 1920x1200, so it should be fine. My a1222+ is actually hooked up to two monitors (different size but the same resolution), one over DVI to the motherboard, the other over DisplayPort to the Radeon. While the radeon is there the motherboard outputs nothing, and I only see the boot menu and kickstart loading progress.
I'll check what resolutions I have in the prefs.

Thanks
