I purchased an AMD FirePro W5100 to play QubesOS on three or four screens, and it recognizes up to two of them, but the third one repeatedly recognizes HDMI (using a DisplayPort to HDMI adapter) on and off after startup.
(The display frame comes on and off in the Display settings).I think the connection itself is working, but is it possible to enable QubesOS to use a third device?
Do you have all 3 monitors working in non-Qubes OS system?
You can boot from some Live Linux OS (e.g. Fedora Live) to tst this.
Maybe it’s because of this:
If you’re using four active adapters, that could be the problem. From the Eyefinity FAQs:
This DisplayPort signal can also be synchronized with DVI and HDMI signals, but only two of these signals may be utilized on an AMD Radeon™ GPU. This is why AMD Eyefinity technology requires a native DisplayPort signal for the third (or higher) monitor.
And from footnote #1 of the FirePro W5100 datasheet:
A maximum of two active adapters is recommended for consumer systems.
So I would try two active and two passive adapters rather than four active ones. Regards, Joe
Sorry for the late reply, W5100 was mentioned on this forum and I thought it would work!I had purchased it, but it turned out to be sad.Since there is no choice, I will continue to display only two pieces.
