I would assume RGBS and not RGBHV, for wide compatibility between 15kHz and 31kHz displays - most VGA CRT monitors will accept RGBS/composite sync with no issues. And most (all?) Sony PVMs/BVMs that go above 15kHz don't have Vsync inputs.

Let's see if we get a definite answer from the dev, then.

USA poster, aren't you? Anyway, it'd make sense if the device does the job so that anybody can use it directly with an ordinary monitor.

Try looking for RGB interfaces from other brands RE: affordable sync converters in countries where Extron stuff is expensive... i.e. Inline branded ones, Altinex. Try searching 'RGB interface' on eBay

Bet that's what's being used, in conjunction with a SOG stripper/green cleaner.
Keep in mind that a stock PS2 (3000) can output buffered H V C sync from the first 3 pins on the last encoder.
1881 ics helps you output a h\v\c sync from video\csync signal... but not combine sync signals. I think that ps2 has internal c\h and v sync separately generated, maybe he took it from there,
The product is plug and play, no mods required and works on all models so he has not pulled HV sync.
Comp video is fed into the stripper.
C H V sync comes out. There is 0 need to combine anything, all the options are there.
You could also feed the green channel into the stripper if running SOG mode.
The only issue I see is trying to strip sync from green, then cleaning the extra voltage off green. Its a real PITA with lack luster results.

I will, thanks, but hopefully it's not needed for this.

Glad I wasn't the only one confused by what this actually does concerning sync (specifically RGsB in 480p).
The Tindie link provides more info.
Some features of this board:
- Onboard power filtering through decoupling capacitors
- No external power required
- No buttons to manage
- Dual sync separators and cleaners
- Clean RGBs output
Didn't have this problem with the SyncBaby, and the PlayBaby works fine with my OEV 143, so not sure why the 20L5 doesn't work with it.
The developer thinks that the 75ohm sync is too low for the 20L5 and is thinking of offering a TTL version, currently waiting to hear back. I have other ways of playing PS1 in RGB on the 20L5 so not a big deal.

Have you heard back on this? I poked the developer on tindie a few days ago asking about compatibility and haven't heard anything back yet.
He replied to me just once (he said he's been busy with his day job) and said that he hasn't heard back from another person that was having a similar issue, but I could return it for a refund. I agreed and asked him for his mailing address, but haven't heard back after that.
Oh well, it would probably cost too much to send back to Canada, and I can use the PlayBaby with other monitors (it also worked with the 20L5 when I used an official PS1 AV breakout box with CVBS as sync, although the picture would shift to the side a bit on bright screens for some reason).
Is this still the recommended option for PS1 DSUB adapters that's readily available? Tindie store is on break but I assume they're in stock. Wish it had a bit more of a case for strain relief though...
Other option I know of is Jeff Chen's design but those usually aren't on sale anywhere as far as I know.
You could maybe have someone make an adapter using Jeff Chen's designs if you know someone who can solder and has a 3D printer. Tempted to do so myself, but I don't have a 3D printer.
I'd like to recommend the PlayBaby, but it has compatibility issues in my experience. In addition to my 20L5 shown in my previous post, it also doesn't seem to work properly with my GBSC, it shows black as blue, same as some D-SUB cables from Retroaccess.
The lack of a case also makes it seem overly fragile, doubly so for my unit which is really hard to insert/remove.

Thanks, should have read through the thread more carefully. I can't say I love the exposed design of this thing, but DSub options are few and far between. I have the skill to make Jeff's design, just can't be bothered with the time investment.
Maybe I can grab some BNC RGBS cables somewhere and add a DSub adapter at the end?
I'm not too fond of dedicated BNC cables nowadays either, as they're expensive and I've had at least one pin get a bad connection over time.
For PS1, I just spliced in 220uf caps into a PS2 component cable and use a Sony AV breakout box I modded to output luma on the yellow RCA jack, and use RCA to BNC (and BNC to VGA when needed).
Seems the flickering part of my problem is power-related. I'm officially going to give up on the one beefy power brick powering all barrel jack systems idea from My Life In Gaming- I've had nothing but trouble with it with multiple sets of cables and PSUs. Each console will be back to its own dedicated power supply from now on.

To best of my knowledge, this is the first DSUB adapter available for the PS1/PS2 gaming console. There was an official VGA cable made for the PS2 that came packaged with a distribution of Linux on the PS2; however the cable reportedly only worked with the Linux distribution (for some reason).
Extremely hard to find, I picked up two back in the day. It was years before Blaze repurposed their software boot disc for component output, but it essentially does the same thing in (SoG) VGA.
