Hello I Have been using Ubuntu two years now and i finally decided to treat myself and get two identical Acer R240HY 1920x1080 Monitors. Everything works as intended with only one monitor. As soon as I restart my computer with the second monitor attached to the dvi splitter the the display settings show Unknown Display and that the locked resolution is 1024x768

I have tried deleting the monitors.xml config file and it didn't work. I tried downloading any proprietary drivers, which did not work. After failed attempts to install Radeon services and drivers: I reinstalled Ubuntu twice.

My neofetch is:

Any help would be appreciated.

EDIT

As requested here is a link to the dvi splitter that I am trying to use:

I also tried to check my error logs on a whim and found that there are many errors like so: 

Jul  6 15:48:33 Azimov kernel: [  187.392635] [drm:radeon_dvi_detect [radeon]] *ERROR* DVI-I-1: probed a monitor but no|invalid EDID
Jul  6 15:48:33 Azimov kernel: [  187.675779] rfkill: input handler disabled
Jul  6 15:49:36 Azimov kernel: [  250.219737] radeon_dp_aux_transfer_native: 158 callbacks suppressed

I wonder if this could be a kernel issue or something. Thank you to any and all.

  • Just a comment that screenfetch gives a different splash screen you may prefer over neofetch: https://askubuntu.com/questions/1020692/terminal-splash-screen-with-weather-calendar-time-sysinfo/1020693#1020693 Do you have a link to this "DVI splitter"? – WinEunuuchs2Unix Jul 05 '19 at 02:29
  • Edited in the dvi splitter product page. Thank you! Tried out the screenfetch. I like it! – Adam Kalinowski Jul 06 '19 at 20:05

Before buying on Amazon I check the user reviews. The dvi splitter in question only gets 2.6 stars out of 5. In particular this question was asked:

  • Will this product work with 720p, 1080i, or 1080p signals?

And the responses (from your point of view) are not good:
