Today i went out and bought a Wireless Keyboard and a mouse. I am hooking up my Macbook 13.3 to my tv with the apple connector and the RGB cable. However the screen seems to be to large for my tv. Everything on the desktop looks normal but when I open firefox or any other application it is HUGE. I went into my tv settings and put it all the settings and nothing looks good. Is there a setting on the mac i should switch? Thanks for your help!!!!
