hi all, new to this so sorry if its simple or has been covered. I connected my macbook to my lcd via the hdmi connection and all is good but i can only see my photos on the screen in a very random order. i turned off my screen saver and wallpaper on the laptop but the photos still change on the tv screen. All i want to do is watch my itunes movies on a lcd. please help, again sorry if it sound to simple!
