Good point, the old RGB interface (usually 3xBNC connectors) is truly Red, Green and Blue colors with either separate H & V sync lines (i.e. HD-15/VGA connector) and/or Sync-On-Green, whereas modern Component Video still uses the RED/GREEN/BLUE colors on the RCA connectors, but is actually Luminance (Y), B-Y and R-Y, hence the alternative name "YPbPr". COMPONENT VIDEO TO VGA CONVERTER Box performs the requisite color remapping. [Although a few old Monitors selectively support RGB and YPbPr color mappings.]:
FYI: I found downloadable PC drivers for Princeton AR2.7 and AR2.7AV Monitors, which begs the question as to WHAT does your AR2.7T support:
ONLY Resolution, Vertical & Horizontal frame rates are as follows, so I would conclude VGA I/F MIGHT NOT support 720p or 1080i on the VGA I/F and you may have to use one of the two so-called "RGB" interfaces...which makes sense if you are connecting devices other than a PC to the Monitor:
Fol. review explains that it comes with VGA and two HD-15 (RGB/HV) interfaces, so the aforementioned Converter Box should get the job done:
And also provided a LINK to Princeton Graphics that I was having a hard time Googling:
But it looks like a Web-Squatter has taken over that sitename.....
So, I've come up empty trying to find a proper MANUAL....so I may not be seeing all of the pertinent info.....
