Samsung 213T: check signal cable

[mattw]

when i turned the monitor off, i got the above message. ive rebooted several times and checked all the connections. per samsung's site, when the computer is off, cable disconnected from cpu, i should get this message so they say the monitor is ok; the problem is video card, drivers, etc. i reinstalled the drivers.

i have an old 17" CRT and it works when connected to the port the 213T uses so im assuming its not the card.

what else can i check? please help as the CRT looks like crap next to the 2001fp. oh, the cpu and monitor are 5 months old.

TIA
