what's BNC?

I got my dell bargain Samsung 900NF monitor ($289 shipped) the other day and still awaiting the arrival of my new pc. I noticed that there are 5 rather industrial looking connections on the back of the monitor that manual refers to as BNC. I've never seen these before. Are they usefull? My computer has a Geoforce Pro video card, can I use these bnc's or should I just use the regular connection?

BNC is a type of connector, kind of like an RCA connector, but it twist-locks on.

You'll need to get a VGA to BNC cable to use those connectors on the monitor. Not that unusual, but if you have a VGA input you might as well use that.

The cool thing about BNC is it isolates the individual video signals, so theoretically, you can get a cleaner picture. Kind of like the difference between composite and component video on a DVD player.

I have an old Nanao monitor that has the BNC connectors. There's a noticeable difference in video quality.

I'm not sure about this - you may be right. But the reason why the picture is clearer is because it is a better matched impedance line than normal RCA cable which have transmission losses, And the connectors are not as lossy as well.

Just a bit from the EE perspective.

BNC is what is commonly used in cctv setups much better then rca and coaxial, but probably wont be much better then vga.
