Hello,
I am trying to determine if I have the correct cable for attaching
a Sony CPD-1304 Trinitron (Multifrequency) Color display to an Orchid
Prodesigner Plus VGA card.
The cable that I am using appears to allow correct operation
(I can display images at all advertized resolutions) however
the output of the VMODE utility (shipped with the Orchid
card) has me puzzled. VMODE reports that the attached display
is a PS/2 8514 Interlaced display. This leads me to believe
that the Orchid is seeing the Sony as an interlaced display
when in fact the Sony can accept an interlaced or non-interlaced
signal (non-interlaced being the preferred method here). The
Orchid card is documented as being able to generate an interlaced
or non-interlaced signal.
Upon reading the Orchid User's Manual, I found that the Orchid card
determines the characteristics of the attached display by
examining the state of two of the cable wires which are used
as id bits. The three states that are recognized are as follows:
1) Fixed frequency analog monochrome (8503) or variable frequency anlalog
monochrome
2) Fixed freq. analog color (8512, 8513) or variable frequency analog color
(non-interlaced)
3) Dual freq. analog color interlaced (8514) or variable frequency
analog color interlaced.
I would expect the Sony 1304 to be in the 2nd category. If this
is indeed the case, then either the VMODE program is in error
or I have the wrong cable.
My request is as follows:
Could someone who has the Sony 1304 and Orchid Prodesigner Plus
combination please run the VMODE program and let me know what
type of display the VMODE program reports?
Also, if anyone has the Sony part number for the correct cable,
that would be good to know as well.
Finally, is there any easy way to test whether or not the display
is receiving an interlaced signal?
Any other relevant information is welcome. Please email responses
and I will post a note summarizing the results of my query.
Thanks much,
John Garnett
