I have an older Toshiba 32" TV without HDMI in my workshop. I tried hooking up my ROKU stick with a HDMI to Composite (red, yellow, white) adapter. The menu appears fine but when you try to actually view a show , you only see a small portion on the screen. Its like the picture is way to large for the screen and you only see a portion of the top left corner. I cant find any setting that will correct this. Anyone have any ideas?
