Screen Appearance

Now I am totally confused as I put up a post about my screen which I cannot put right. Some areas have larger print than the others, the whole thing is a dogs dinner. However, I got a message saying I had put two messages on two different forums. I never knew I had done that! Now I am not sure whether this is the right forum for my request for help or whether I should be somewhere else??

I cannot get the text the right size, the lower left hand side of the Outlook panel has larger text than any other and the top of the screen with the tool bars are way to big too also, the text about the emails is too smal!!. What should the screen resolution actually be?? How the blazes do i put all this right please? If this is not the right panel for my cry for help, please tell me which one is??
