AMD Radeon Navi GPU

Are you getting some kind of issues using two displays?
I’m wondering drive another display. Actually I have an 4K philips 27” display. Two of them side by side would be nice.
But will it work?

I've got three displays running on my PowerColor RX5700 without any issues. One display is 4K@60Hz and the two other are 1440p@75Hz.

Thank you!

Let's go shopping!

What connectors are you using for these? I can't get my RX5700 to run all three monitors. Two DVI, one HDMI. Tried WAG/Lilu and different SMBIOS but I can't find a solution.

All three are connected using DisplayPort. Latest Lilu and WEG. SMBIOS iMacPro1,1. Boot arg: agdpmod=pikera
I have tried using one of the 1440p displays with HDMI, and it worked but with 60 Hz as max refresh rate.

Gotcha, thanks. I'm currently using Lilu, WEG, iMacPro1,1 and the boot arg but it won't work. I'll have to give it a go with a third DP cable.

Yes. Geekbench 5.1 Compute OpenCL.

Is this the test I should run?

yes, that’s the test. I asked because my 5700XT gets a similar result

it's a great result for a budget card.

Just updating you, I bought a second 4k display, both are running great!

Any progress?
