How to get the pixel/dot clock of an arcade game for the OSSC

I will state up front that I don't know anything about phase...

but in my experience with the OSSC, taking someone else's phase adjustment and applying to your TV/PCB/console may not have the best results.

Firebrandx had some useful OSSC profiles that that I imported. They looked pretty good but the phase needed to be adjusted slightly to crisp up the image.

I am making an assumption that everything looked great on firebrandx's setup.

I manually adjusted the phase for each console and for my multis. 240p test suite helps with the adjustment (where it's available). I had to do some by eye.

The OSSC pro has automatic phase adjustment that seems to work pretty damn well.

Retrotink 5x has it as well but I think it looks awful. I'm, not a 5x fan.

What about the RT4k? I’m hoping it’s more like the OSSC Pro than the 5x.

I hear great things about the 4k but I hear great things about the 5x too.

My issue is specifically with the automatic phase detection of the 5x. In my experience, the clarity of the game changes as I'm playing it. It's very annoying.

I purchased the 5x for it's downscaling capabilities. It let me down in that regard as well.

I got the ossc pro because of the troubles mentioned above. I'm very happy with my purchase. Phase detection is excellent and the downscaling is amazing.

I like other retrotink products a lot and have them in my setup.
 
@twistedsymphony Funny, I dialed in all my arcade boards but somehow it looks like I missed my STV.

Gimme a little time please and I'll see if I can get you some numbers to try. I don't have the same display as you though and the original OSSC doesn't play nice with all displays and sometimes it can be a hassle to get a good lock.

As for phase, yeah phase is unique to each user so that won't always transfer to other setups easily. Fortunately phase is pretty easy to figure out if you carefully look at the pixels as you adjust it. That's after everything else is setup though. At least, that's how I do it.
 
I did mange to get it looking ok. just going through the settings seeing how each one effected the image and tweaking. Once I got the whole image to display without getting cut-off The biggest improvement was bumping up from 2x to 4x, even though that puts it at a higher res than my monitor, that for some reason cut down on the noise (it's still present but it's better). doing that induced some weird color banding on the left side that I was able to hide with some settings on the monitor itself.

it's still far from perfect but at least now it's a significant improvement over the taito scaler

systems like the STV and the Sony ZN boards are hard because they switch around resolutions per game, and even some games change resolution mid game depending on the screen.
 
That's good to hear, glad you made progress. Yeah games with res swapping can be a pain on older scalers for sure.

Good luck!

FWIW I’ve found lowering the R, G or B values/intensity on the OSSC (via the “Video in Proc”) menu can greatly reduce and/or eliminate color artifacts. I used to have some wicked green push/noisy pixels on CPS3 that had to have my G level adjusted downward to alleviate.
