Samsung Display Quark?
I just purchased a Samsung 955DF 19" crt flat screen monitor. Great
colors and resolution. Looks nice but it seems like the picture tube is set back a ways from the front bezel causing a black edge (non displayable portion of tube) around the screen. I have the screen adjusted to max, tried different display sizes and refresh rates. Still have this black portion between the displayed area and the front bezel. Is this normal? It sort of driving me crazy. Any information is appreciated? Nick |

Are you absolutely certian that it is not a "Black Surround" crt, like
Thompson, Sony, Toshiba, etc use?? Are there small "tick" marks centred on vertical edges of the crt? "Nick Funk" wrote in message ... I just purchased a Samsung 955DF 19" crt flat screen monitor.

I don't see any black tick marks. I do notice one small pixel centered
on each side of the display area. It is located just outside of the display area in the black area of the screen.

Nick,
This is normal for this type CRT. Crazy or not. Those single "pixels" are the tick marks on that "Black Mask" type CRT that Arthur mentioned. They are there to visibly mark the center of the viewable area for geometry alignments by the equipment that sets up the alignments on the assembly line (and later for technical adjustments by qualified techs). You are also seeing the thickness of the glass which is thicker than what you were accustomed to as well as the front bezel being smaller. Good Luck, Bill Jr "Nick Funk" wrote in message ...
