I’m currently running Kubuntu 19.10 with kernel 5.3.0-42-generic and a ROG Stirx RX 570 graphics card. The card has 4 video out ports; 2 dvi, 1 hdmi, and 1 display port. I’m currently running two monitors. One is through the hdmi and the other is through dvi using a dvi to hdmi cable.
I recently moved and to save space connected a Mac Mini to the large screen 4k tv. That gives me an additional 27 inch monitor. The extra monitor had dvi and hdmi ports. Yesterday I connected the third monitor to the dvi ports on the graphics card and the monitor but the monitor wasn’t receiving a signal.
Is there an issue using both dvi ports from the gpu in linux or are three monitors generally a problem in linux? I’d like to find out before ordering a display port to hdmi cable. No reason to order it if it probably won’t work. Thanks
