This is an easy task.press the minu button of your screen until you reach the option of stretching the screen ( a square with 4 arrows at corners).
You can also adjust the resolution by clicking display icon in control panel.

Check the button for picture size and adjust accordingly.

The inverter is usually the cause if you have perfect audio but the screen is black. You can get inverter boards from www.tvcircuitboards.com

You can close your browser window by clicking on the red "x" in the top right hand side corner of your screen. The red "x" means "close". The "square" in the center next to the "x" means make "bigger". The - key next to the square in the upper righ hand side corner of your screen means "minimize". "Minimize" means bring the window to the bottom of the screen. It's like tucking it away or hiding it. If your window is full size and you click the minimize button, it will make the screen a smaller square in the center of your monitor. If you click it again, it hides the window at the bottom of your screen. You can see which windows re open by reading the labels at the bottom of your screen. To bring a screen back up to regular size when its minimized on the bottom - just click on it with your mouse.

any display in the corners of channel number av etc ?? if you turn the volume up and down does that show on the display if not likely to be a dead panel

what is the solution?

Turn off the Picture in Picture (PIP) option using the remote control. I had this problem and it worked for me!

This TV has 2 main circuit boards (2 LCD backlight controlers): the Power Supply board may have fried the video board on it's way out ...
You can either arange to have the TV replaced under warenty if not have it serviced. In any case best of luck with Vizio support line.

Everyone bought this TV because it was so cheap... now we find out why: Vizio cuts corners on everything from engineering to support!! All brands are not created equal. Sometimes you get what you pay for.
