Sony CPD-9000 Resolution

[vol.2]

Hey there, does anyone know if these monitors can do interlaced modes at all? I read the instruction manual and it doesn't mention interlaced at all, it seems they are intended to be used with early computer systems so the manual only talks about hooking them up to MSX computers and the like.

Basically, it says you can do either analog or digital RGB, at 640 or 320 x 240, no mention of interlaced. Would it make sense that if it could do 240p at 15kHz refresh rates, then it should just happily display 640x480 interlaced?

There shouldn’t be any issues with interlaced / 480i

Ok thanks

I bought one of those Sony 9" CPD-9000 Trinitron RGB monitor off of ebay many moons ago. It works like a charm but has a hard time with handling arcade jamma pcbs that have "high RGB output levels" (i.e. -- the Cave DoDonpachi Dai Fukkatsu v1.5 pcb comes to mind with it's default well-known "high RGB output levels"). The fake high-res Seta Aleck 64 game of Hanabi De Joon runs in 640 x 240 res mode along with Namco's Mr. Driller 2 arcade pcb which also runs with a 640 x 240 res mode as well. It handles tate arcade pcbs without any problems with 240p input indeed (15.7kHz low-res with 320 x 240 is the "sweet spot" and looks super "razor-sharp" indeed). No screen burn-in issues to deal with/convergence is dialed at the factory as I got it brand new back in the day -- you can't get 'em brand new nowadays.

A special proprietary 8-pin cable is needed to get an RGB signal input with this particular Sony RGB monitor and is quite hard to find nowadays -- very uncommon these days.

Thanks for the reply.

I actually have the cable as my monitor came with one when I bought it!, along with the original power cord and the foam from the original box. When I opened it up, there was absolutely zero dust on the high voltage components, and the whole thing is just so minty fresh that I don't think it had ever been used before; it's basically brand NOS.

I got all 480i modes working, and it happily takes my Playstation 2 via RGB and also the input from my Raspberry Pi 4 through Mike Chi's RT Ultimate. I can play my Neo Geo stuff through that (I bought the games from GOG and packaged them as zips for the emulator).

Unfortunately, I think the yoke got a tiny bit shifted during shipping as the image is just a tiny bit tilted. It's not so bad as to be generally noticeable in play, but it kind of bugs me and I might have to correct it. Hopefully it won't make a huge difference in the convergence, but if it does, the internal controls actually have electronic controls for both vertical and hor static convergence, and separate top and bottom vert convergence pots. There is an enormous number of correction pots in these monitors for someone that wants it to look perfect.

All in all a really great little monitor and so happy to have one.

Only thing is I can't find the Service manual, so if anyone has a lead, pls let me know!
