Forum:SH:View of Site Question

My screen res is 2560 x 1440. The actual articles only occupy about 50% of my screen; on the sides of every single page are the horrendous ugly blue banner-things featuring images of characters from the new cartoon I'm never going to watch. Howwww does one get rid of them/make the actual articles take up the whole screen? (Side question: any way to auto-disable the annoying videos at the top of certain articles?)
