Just got a LG Electronics 915FT that has a BNC connection. I also purchased the BNC's for it (DSUB to BNC). One thing to keep in mind with BNC's is you loose the plug&play feature of the monitor, though mine also has a USB hub and the monitor can be controlled and recognized with the USB connection. Nice monitor, no horizontal lines which drive me crazy. I think this is a great alternative to the Trinitron tubes.
I am going to be using 1600x1200 all the time and will go higher from time to time. I want to keep the picture as good as possible, so I got the BNC cable.
