Aspect ratio won't change to 16:9 for my nintendo wii. it stays as 4:3 even when i change the output setting on my wii to 16:9. the nintendo wii support said that you have to change the aspect ratio on the tv itself as well, but i couldn't find out how. i am also using the nintendo component cables (bought separately specifically for the wii).

You can change how your tv displays in the video setting menu under display. You will have a choice between 4:3, 16:9, 16:10, cinema or automatic. I think to fill your screen the best you should choose 16:10 but this is not going to guarantee that all channels will fill the screen. It still has to do with how it is being broadcast to you.

Your tv is going to default to whatever the resolution is that is being pushed to it. Your source is probably only outputting a 4:3 format. It can be forced into 16:9 but will not fill out screen. You will just get a letterbox.

Hi
Having looked at the full manual - downloaded from here and savable:
http://tda.panasonic-europe-service.com/docs/2z54662404z3z38916z656ez706466z22zdf06e277f71e6367f9e09db70241478cb0ad23ae/tsn3/data/ALL/HXWA30EG/OI/902781/vqt4x32.pdf
I think you will find that you cannot actually change from 4:3 to 16:9 aspect ratio for a particular pixel sized picture. When you set the pixels for the picture you want, the aspect ratio is set automatically.
For example:
16Megapixels 4608x3456 4:3
12Megapixels 4608x2592 16:9
See page 96 of the manual mentioned above for a full table of Megapixels, size, ratio etc
Therefore changing the picture size from the simple menu changes the aspect ratio but you do not have control of the aspect ratio for each size, in other words you cannot take a 16Megapixel picture at 16:9, it has to be 4:3.
Hope this has been helpful
Cheers

Different channels are broadcast in different aspect ratios, depending on the network and the show(s) being broadcast. Many older show are still broadcast in the 4:3 ratio to avoid distortion. Currently, there is nothing in the broadcast signal that tells the TV what aspect ratio to use. Therefore, TV remotes have a selection button (mine says "P.SIZE") that allows the user to change the aspect ratio to optimize the viewing experience.

Check the settings on your laptop to make sure it is outputting a resolution that the TV will support.

You should be able to change the aspect ratio to fit the size of your screen. This will be the 16:9 4:3 16:10 settings.

You can access these by going to MENU---> PICTURE -----> Select ratio that works----> exit out and watch TV.

IF this will not fix it you need to look into the signals being fed to the TV as sometimes they can have a funny effect on the output picture. Some cable boxes will alter the picture and then it won't come out right on the TV. If it is all inputs doing this tho then changing just the Aspect ratio on the TV should solve the problem.

Vizio has a set of buttons on the left side where you can access your settings and change the aspect ratio of your TV. Though why you want it changed is beyond me. Wide screen is for 16:9 aspect ratios. At 4:3 (Standard) you won't be using your full TV picture.

LENS MEMORY means that

You can save and name the adjusted ZOOM/FOCUS,

H-AREA POSITION and V-AREA POSITION there is just 4 adjustment settings in

memory excluding ASPECT RATIO the aspect ratio depend on signal but you can change manually when needed.

these are all type of signals and there possible aspect ratios

hi,
first of all check the video setting of ur DVD player or satellite receiver which ur connected to the projector. in its video setting select output video format aspect ratio as 16:9. the projecter will output the format what it get in its input.
u can elect the aspect ratio in the projector remote just press the ASPECT button to select different format
ok

Aspect ratio is limited by source material. Even if it's set at 4:3, it will still display 16:9 if available such as in movies.
