I know this post might be better off at the direct-view CRT forum (I already posted this problem there) but I figured members over here could be familiar with the setup I'm trying to do and the related connections.

I've got a 19" CRT PC monitor with 5 BNC inputs additional to the VGA (D-sub) input. These BNC inputs are labeled R, G, B, V-sync and H-sync. I was wondering if it would be possible to connect my PSTwo to the monitor through my PS2 Monster component cables and some RCA female to BNC male adapters (except audio RCA outputs ;) ). If I remember correctly, the PS2 Browser Setup has an option to change between RGB and Y/Pb/Pr outputs.
The problem would be the two remaining BNC inputs, H-sync and V-sync. Are both or any of these signals embedded in some of the other outputs? Are both of these signals needed?

Thanks in advance!

I don't know either the PS2 nor the monitor, but I doubt it puts out RGB on component connections. If it does, it is likely RGsB.

You monitor should be able to handle RGsB, RGBS, or RGBHV on the BNCs (google if you don't know what I just wrote).

I think you need a playstation forum. Basically, you just want RGsB, RGBS, or RGBHV out of the PS2, they should be able to tell you how to do this.

Tranz - if you do find a solution, please post it here. I found the same option in my PS2; hooked it to the inputs of my VP30. Never got it to work. Tho the component/Ypp option works fine - I was just messing around - wasn't using the RGB input on the VP, since it doesn't take the computer res I run, and my component inputs were full.

But - never got it to work; and it is tough to fix, since once you set the PS2 to RGB, it doesn't have any output over component - had to dig up the coax adapter just to change the settings back. Gaack.

The monitor is not extremely old but the technical specs have been removed from the site it is a Hyundai P910+

Thx for your response

:eek: well that turned out to be quite an important fact to know. The main reason I haven't tinkered with it using BNC/RCA adapters was the remaining two sync inputs, which I don't know if the CRT would accept sync signals alternatively from any of the other inputs. (RGsB is sync on green right? Is this a standard RGB output type from consoles?)

EDIT: should I mess up, I could change settings back with the original composite outputs, right?

It outputs sync on green AFAIK. You could use a sync splitter circuit (cheap and easy) to get composite sync or H and V sync, or if it has a composite cable that works at the same time, you could try plugging that into the composite sync input on your projector and it may find the sync from that.

I remember looking into this a while back. From what I remember, Sony disabled (or crippled) the RGB out. It had something to do with the RGB output bypassing anti-piracy protections or something. I also seem to recall that there was some sort or hardware hack that could be done to "fix" the issue, but in my opinion, its a lot more trouble than its worth.

I'm interested in that sync splitter circuit. Any idea where to buy one or find plans to build it?

Would there any difference in PQ from using independent H and V sync cables from using the combined sync input?

About the component cables, these are the 3-video + 2-audio signal Monster brand.

Thanks for the info! :)

You could probably just use the venerable LM1881 - do a quick google on it and you should find some schematics pretty quickly - the chip is cheap and does the whole job pretty much.

I have never seen a difference between using composite sync and separate sync - I had to steal one of the sync cables off my projector to use in the house, and never saw a difference so never put it back again, the NEC switcher has the option to output composite sync regardless of the source, and I just use that now.

Just in case you were too lazy to google.

I believe you people have now given me all the tools and directions needed to start with this "experiment"
Thanks to everyone in this thread for sharing this space and your knowledge/experience in something not directly related to your forum. VERY much appreciated.

I'll post whatever comes up with this.

The "crippling" of the RGB output is just disabling DVD playback. DVDs will always play back in component with Macrovision, unless you either install a small FPGA with a lot of wires inside the console or connect one pin of the video encoder to ground. I don't think this matters, though. Nobody in their right mind watches DVDs on a PS2. The lasers fail quickly anyway, and the PSTwo is the most unreliable piece of...electronics I have seen.
I have worked repairing PS2's. Had they not brought me lots of money I'd call them something not fit for writing here.

BTW, the PS2 does output sync on green. Stripping sync from the composite using an LM1881 works fine, too. I have used both. Having an FPGA in the machine is very convenient because one can use it to force progressive scan on all video modes, which makes the picture much nicer on a CRT projector.

A message to dokworm as his pm quota is full

I have a older projector and need a sync splitter to use the yuv output of a dvd player and input the signal in rgbhv signal into my sony vph1020qm
can you contact me as you seem to know all the tricks

Back in the day I built a few RGB cables for the PS2 and Xbox. I still have a few of the LM1881 chips if anyone is serious about making an adapter I'd be happy to share them. When I got mine the only place I found online wanted to sell a minimum order of like 20 or something.

crowsss - to convert yuv to rgbhv you need a 'transcoder'. The discussion here has mostly been about getting RGsB to RGBHV by stripping the sync from green.
