For example google.com has links in the upper left but I can just barely see the bottom of the text. There is screen settings in the Opera browser but only for screen width not height! (or am I missing it?)
I have a 53" 16:9 HDTV and the screen input is set to FULL which should allow complete display. (and is the only setting TV will allow when input is from component 16:9 inputs)
Welcome to WiiChat.
First, make sure the widescreen settings in the Wii Settings Menu are correct. Then you may need to adjust your TV to Widescreen Display instead of FULL.
...But if there's no way to set it to Widescreen display, you may need to change the screen to standard 4:3 (or whatever it is).
All my online info is on my profile including Wii number, game friend codes, etc.
