iPC not outputing on monitor 1

Have an iPC that seems to have an issue with the onboard video. When the console boots up I see a BIOS screen that I have not seen before. It's a graphical screen instead of just text. After that the screen becomes distorted and then a few seconds later it boots up with monitor two thinking it's monitor one. I am thinking that the onboard video has gone and not fixable. Is this a correct assumption?

Thanks a bunch
