Difference between DVI and S-Video?

Right now I have my computer running to my Sharp Aquos 26 inch LCD. I want to eventually be able to use this as my TV and computer monitor. It has a strange resolution of 1366 x 768. Right now I have it connected to my PC using an S-video connection and it doesn’t look very good, and I’m using a 1024 X 768 redsolution. This leaves me with about a half an inch of black on both sides. Someone told me that using the wrong resolution could actually damage the LCD, is this true? If I switch to DVI will text and images appear sharper? I’m also thinking about using power strip to get the exact resolution do you guys recommend this program?
 
Hi, I'll try to help with my limited knowledge...hopefully others can clarify if necessary.

Well Svideo, that's made for TV's....you have your standard RGB component cables, then Svideo, then composite cables, each getting better in quality for TV's.

DVI is the Digital Video Interface...made for computers. Digital signal from computer to monitor, instead of converting from Analog to Digital like most monitors.

So the DVI supports much higher resolution, and would be the best for your Aquos TV...as Svideo supports the TV resolution, which is like 320 or 480 lines I think.

I've never used powerstrip, but give it a try, i assume it can't hurt. :)
 
Powerstrip will let you set custom resolutions, but if you have an nvidia card, the forceware drivers will let you do that without any additional crap.

DVI will result in a far sharper image, as well as better color reproduction. It will let you take your TV to its maximum.
 
What's happening is that since svideo in an analog signal it has to get converted from the pure digital connection that we all love which results in a loss of quality. The highest analog signal for a TV will be either VGA or Component but it's much better (and simplier) to go with DVI if you can. If you do go DVI make sure you use a DVI-I cable.

I need sleep now. :)
 
Actually in order of quality from least to greatest of video connections is coaxial cable(F-Connector like standard tv cable), composite, s-video, component, VGA/RGBHV, then DVI,HDMI and SDI are all pretty equal as full digital transports.
