It’s been just over a month now since I started using my third Samsung SyncMaster 215TW. I am happy to report that this particular unit has performed flawlessly and I have not seen the vertical blue line that was displayed in the other units I had.  At this point I would say that the other units (which were close in serial number) were simply a byproduct of poor components installed during assembly.

I have always thought of Samsung as a leader in LCD technology.  This experience has not changed my mind.
