Can anyone here help me?

As you can see my colours are off and I can’t seem to figure out what I have done wrong. I know it is something simple I am missing and I would really appreciate a nudge in the right direction.

I have tried the framebuffer patching but I do t really understand the values I am using. I think it may be something to do with my connectors but I just can’t figure it out.

Thank you to anyone who reads this or can offer some help.
