Im currently running on a rtx 2060 in my build and i deciced to go streaming and i thought if i put my old gpu gtx 1070 as stream decoder. So after putting in my old one the screens started to flicker on booting and finally it booted up on 1 screen of my 3 monitors and i looked up in device manager and it only detected my gtx 1070 and rtx and gave an error code on my 2060 while al my monitor inputs are in my 2060? any help to keep them running seperately or any tips?
 
Solution
Your gpu cards have to match to use them in sli. You cant use two different gpus for two different monitors. You can use onboard graphics, if you have them, and a gpu at same time but this wont help you in streaming probably.
