Computer not showing on full screen on ext.

I hook up my laptop (dell studio 16) to my 50" lcd tv and it only shows on about 60% of the screen. is there a way to get it to show on the WHOLE screen?

 

Under catalyst control center, displays and desktops, configure, scaling options, move the slider all the way to the right, apply.

 

catalyst control center? sorry. a lot of this is new to me.

 

Find the correct resolution supported by your tv. What model is your tv?

 

the tv is a vizio, i think it's actually 53". Full HD LCD that mean the laptop wont show full screen unless it's 1080p?

 

Is this the HDTV that you have? Vizio VF550M

Or is it this one? Vizio VF550XVT1A
http://www.vizio.com/flat-panel-hdtvs/vf550xvt1a.html

They're both 55" LCD HDTV's that support the following resolutions via VGA and HDMI.
640x480, 800x600, 1024x768, 1920x1080

 

this one. http://www.vizio.com/sv470xvt1a.html

i checked the model number on the back.

 

How are you connecting to it? HDMI, VGA, DVI, Composite, etc?

 

It says it supports the following resolutions.
Computer Support: 800 x 600, 1024 x 768, 1366 x 768, 1920 x 1080

Also, what display aspect are you viewing it in?

 

This was pulled straight from the owners manual.
