I am debating between an 18" computer monitor and a 20"+ TV. I like how the monitor comes on when the PC gets turned on, but I think a larger screen would look a bit better. What type graphic card and what settings should be used if using the S-Video mode of a graphic card. Does any one recommend a particular model? Are there different considerations if I end up using the 18" monitor instead? My motherboard has an AGP slot for video. Does amount of video memory effect the picture the same if you are using a monitor vs. a TV?
