Hide your sheets which you are using in dashboard,
Put the dashboard size to automatic. So that whatever the screen resolution you are viewing based on that it will render.
If you are using Fixed with some resolution and if that resolution doesn't while viewing the report you will get a scroll bar.
Hope this helps.
