I have a motherboard that I am firing outside its case, and I can not get it to work on a certain monitor. It WILL work on an older monitor I have, but it will not display anything on a slightly newer monitor. We also know that the newer monitor is good since we just used it. Is there a setting that we are missing or some reason that certain motherboards won't work with certain monitors??? I also have multiple video cards that I can change it out with if that could be the problem... Any help is appreciated.
It would help to list what parts you are using then it will be easier to give some advice, also if its a dual output gpu which port are you using?
