[comp.sys.ibm.pc.hardware] Sony CDP 1304 Monitor

lasky@iris.Berkeley.EDU (Ty Lasky) (08/17/90)

	 Touche = good stuff.
 	 Not only do you get a slick tower system, with a speedy ESDI drive,
	you also get the NEC Multisync-eliminator - the Sony CDP 1304 monitor.



I would like to know more about this Sony monitor, and why it is so much
better than the NEC.  Is this monitor 1024x768 non-interlaced?  Is it
multisync?  What is the dot-pitch (also, what is the dot-pitch on the
NEC, and what exactly does this dot-pitch stuff mean anyways)?  Any other info?

Thanks,

Yes. Although the usefulness of that on a 14 inch product is debatable.

Yes, but it doesn't go down to 15Khz like the NEC 3D. DP is .25 mm.

It just means how far apart the dots are. If you are interested in
the Sony 1304, the Seiko 1450 will be worth looking at. But if you
want 1024x768 non-interlaced, look at 16 inch monitors (like the
NEC 4D) also.

I'm trying hard to visualize world peace. Did it work yet?

The CPD-1304 is a 1024x768 Non-interlaced monitor which uses Sony's
Trinitron CRT technology.  Yes it is multi-sync; sorry I'm doing this
from memory.  The dot pitch (the spacing between the dots, or in this
case the spacing between the slots since the Trinitron uses a slotted
mask) is either .25mm or .28mm.  This is pretty good.

I am biased because I own one and because I've owned a 1302 monitor before
that.  The Sony 1304 is the only monitor in the price range that can handle
1024x768 in non-interlace.  What this means is it's not prone to flicker like
other interlace monitors at the same resolution.  Unfortunately to take
advantage of this capability, you have to get a VGA board that can run at
non-interlace (ie. Video7, Orchird, ATI, etc.).

The 1304 is a 14" multisyncing .25mm dot pitch analog monitor.  It is not
able to scan below 31 KHz, so it can't be used with any CGA or EGA cards (but
then again, it's inputs are only analog, not digital).  This is NOT a problem
since most decent VGA cards will double overscan the 320x200 CGA resolution
into 320x400 to work with VGA monitors at 31 KHz.

The .25mm dot pitch means each trinary color set is spaced .25mm apart.  In
the Sony trinitron tube, the mask is slotted with each color dot spaced like
this: |||.  Each  |  is red, green, blue respectively.  In terms of horizontal
resolution, no other monitor comes close because of this mask scheme.  However
the vertical resolution is not much better then others because of the slotted
mask.

Well regardless, I love mine.  It works great with my VRAM board and even
though it doesn't have the nifty "memory" feature of the NEC 3D, I find I
don't need it anyway, because all my resolutions CGA to SuperVGA are sized
just fine.

If you need more info, email me.

                                           ^^^^^^^
DO these things always have to be so BIG? I don't want such an
ugly beast on my desk/table. Can't you have a nice small one
AND high resolution?
