PS1 RGB cables are supposed to have 220uF caps in them, whereas RGB cables for PS2/PS3 are supposed to have no components in them (the caps were moved inside the console). I have successfully used my PS1-specific SCART cable on my PS2 with no apparent issues, so I imagine you're correct.vol.2 wrote:As to an explanation, it may be that the capacitors or resistors inside the cable are the reason. I believe that PSX and PS2 scart cables are different in that way, and that one of them is supposed to work for both (the PSX I think) but not the other way around.

Re: Questions that do not deserve a thread
Which one of these boards would be better for a 2 slot Neo-Geo CMVS? I want to redo mine with proper video attenuation.
The resistor values are different for each board. Also, one of them uses 220uF caps on the rgb and sync output lines, but the other one just uses a cap on the sync output.

Re: Questions that do not deserve a thread
Does any of you who owns a sync strike remember what to jump in order to switch from csync to hsync?
It's got D1, D2, D3...
Sorry to bring this out here, but the sync strike thread seems like got abandoned about 5 years ago...

Anyone ever use this? Is this the same as a Garo? Ideally connect it to a GSCART switch.
I already have a MayFlash 2:1 Component to VGA adapter. I even fixed the black screen issue on bright screens where voltage drops for 4 frames to 0 with a simple ceramic capacitor fix.
Just curious if this would allow me to connect component consoles such as Wii/Gamecube and route them through my gscart. Of course I would need a VGA to Scart Cable if it does what I think it can.

Re: Questions that do not deserve a thread
You can already connect component sources to the gscartsw by sending Y > G, Pb > B, Pr > R on the RGB inputs. You would of course still get YPbPr on the output side, which is fine for devices that can switch between colour spaces (PVMs, OSSC).ChuChu Flamingo wrote: Just curious if this would allow me to connect component consoles such as Wii/Gamecube and route them through my gscart.

Re: Questions that do not deserve a thread
Does this have everything to do with those PS1/PS2 comparisons that everyone was basing their judging upon? How's it to tell the same capped cables were being on their PS2's at the time?nmalinoski wrote:PS1 RGB cables are supposed to have 220uF caps in them, whereas RGB cables for PS2/PS3 are supposed to have no components in them (the caps were moved inside the console).

This bods a real re-do in some areas.

First, that's only the case with the newest gscartsw model; that's not feasible with any of the older models.makar1 wrote:You can already connect component sources to the gscartsw by sending Y > G, Pb > B, Pr > R on the RGB inputs.

Secondly, even if he did have one of the new gscartsw models that does component forwarding, I think the goal here is to consolidate video formats to simplify video processing on the other end of the gscartsw; to convert YPbPr to RGBS before connecting it to the gscartsw so that you only have to deal with RGBS when it comes to things like scaling and routing, which would also eliminate any need to manually switch between YPbPr and RGB.

Is there a list of TVs that support 24K anywhere?
I have a VIVO plasma TV that runs my Sega 24k 496×384 boards just fine but everything else needs a GBS.

I'd love to hear some alternatives for 24k also. Trying to get my Virtua Fighter boards hooked up to something with native support.

Re: Questions that do not deserve a thread
that's hardly native support, when the image gets rescaled first thing inside. And if you don't intend on using an actual 384 line display (as in 24khz CRT), you can just as well use an OSSC to double to 48khz 768p, which every display on this planet happily accepts. And thinking of 768p, there have been nice 4:3 plasma screens with XGA resolutions.Trying to get my Virtua Fighter boards hooked up to something with native support. I was thinking of taking a punt on a "professional" NEC plasma display but haven't quite summoned the courage yet.
When I first had the chance to pick up a plasma sync I was really excited. Greatly machined displayed, with lots of inputs, heavy built quality, speakers inside the base, back-lit remote and everything, but unfortunately the quality of the panel wasn't up to it. Way worse than your average Pioneer VGA plasma.I was thinking of taking a punt on a "professional" NEC plasma display but haven't quite summoned the courage yet.

Re: Questions that do not deserve a thread
Native in the sense that I don't need any external processing. I have my own reasons for trying to avoid a separate box - firstly it looks like shit in the living room and also my DX902B actually doesn't accept 768p from the OSSC. I would presumably need a dsc301 or similar to bump up to 1080p but I don't want to make my family living room look like a garden shed. No dual/Tri sync monitors for me with a little one running around, and no room yet for an Astro City etc. Just looking for a tidy, discrete setup.
Thanks for the tip on the NEC pro displays. Best avoided then.

If you're talking about LCD, then probably either Dell U2211H or NEC EA231WMI.
I've tested the Dell and the NEC with Gradius 4 (24KHz) - Dell works fine, NEC is kind of picky - need to plug and unplug a few times.
I've tested the Dell with Zero Gunner (24 KHz) - it drops out a lot so I think a sync cleaner is needed.

Re: Questions that do not deserve a thread
Anybody know if CRT Emu Driver supports Freesync on compatible cards?
I want to see if I can get freesync working with fixed framerate low-res games on a 15kHz CRT, mainly for reduced lag. I just don't know what drivers to use.

Re: Questions that do not deserve a thread
So, unless you're talking about something special, freesync only works with monitors that support it. I don't think any CRTs have the monitor-side adaptive tech in them. It works by monkeying with the vertical blanking rate.BazookaBen wrote:Anybody know if CRT Emu Driver supports Freesync on compatible cards?

Re: Questions that do not deserve a thread
I've been trying to hunt down a minor issue on an Ikegami-1517R and I've about given up. I get black streaking to the right of solid white on dark backgrounds. Its extremely noticeable if I crank the contrast/brightness and open the menu (streaks go across the entire screen when cranked). I have a second monitor that is also a 1517R and it has zero streaking when cranked. I've swapped literally every part in the monitor with a known working one. I even double swapped the video processor, RGB board, deflection board, power supply with different ones. If anyone knows of any menu settings that I'm missing to adjust the clamping or anything else I should look at please let me know. At least this is almost never noticeable except when I'm at my desktop to load mame and even then its barely noticeable. I am just curious at this point.
Also: this issue is present with no video signal sent to monitor, and I've tried different power cables and outlets in a different room.

Re: Questions that do not deserve a thread
The idea is to run to an HDMI>VGA or Component adapter, then use Custom Resolution Utility to trick the driver into thinking the monitor is freesync. This part I've done before with a PC CRT, but those go through a "re-sync" process every time you change refresh rate or resolution, which means a black screen whenever you drop below max refresh.vol.2 wrote:So, unless you're talking about something special, freesync only works with monitors that support it. I don't think any CRTs have the monitor-side adaptive tech in them. It works by monkeying with the vertical blanking rate.
So 15kHz CRT's usually don't do that, which is why 240p>480i transitions are instantaneous. And I'll be playing 60fps-locked games, so as long as the frame times are consistent enough, I think I'll have a stable picture, except with lower lag because I won't be using vsync.
I haven't cobbled together the hardware to try it yet though. I plan on doing this in the next couple weeks.

Re: Questions that do not deserve a thread
Has anyone ever compared the video quality of PSP games from a PSP into the OSSC vs PSP games on the VITA using a playstation TV?
Re: Questions that do not deserve a thread
When using a PSP through the OSSC you can't get rid of the underscan (272 active lines on a 480p signal). To eliminate the underscan you need a secondary scaler.

Do you have any suggestions for this?

Re: Questions that do not deserve a thread
Scaling with so little resolution available is nothing that I would recommend. You will probably end up with a blurry mess no matter what. For 1080p+ screens the Extron DSC 301 does a nice job of transforming any incoming image from an OSSC.

Re: Questions that do not deserve a thread
Did anybody ever get an HDFury Vertex? Looks like there isn't any reason to choose it over the Linker.
I see their rep is busy peddling misinformation and dodging questions about chroma subsampling over at the avforums.
One member over there was particularly persistent, but didn't ever get a straight answer.
HDFury started out saying chroma subsampling is "proprietary information" (that's bullshit) and finally got around to saying it's *almost 4:4:4* (also bullshit).
It's either uncompressed or it isn't. There's no grey area.
Anyhow, does anybody have one they can throw a test pattern at?

Re: Questions that do not deserve a thread
I don't even understand why they're dodging that question. For 99% of their audience it really doesn't matter. It doesn't matter if you're just running movies through it and it doesn't matter if you're recording the output with a 4:2:0 codec. I don't see it hurting their sales if just outright said, that the source is downsampled for processing and upsampled again (if the output is set to 4:4:4).
Re: Questions that do not deserve a thread

I'm a bit surprised that people insist that it does not pass through 4:4:4 - I have previously used it to modify the EDID of my Dell monitor because MacOS decided that it would really like to feed it 4:4:4 YCbCr and the monitor processes that internally as 4:2:2. I hated the blurry color syntax highlighting caused by that and since there does not appear to be any way to fix that on the Mac side (without disabling System Integrity Protection), I used the Vertex to inject an RGB-only EDID, which gave me non-blurry colored text. To me that seems to indicate that at least for RGB at 1920x1200 the Vertex does not do anything that results in reduced chroma resolution.Anyhow, does anybody have one they can throw a test pattern at?

Of course, that makes little difference if someone is upscaling retro console video as 1080p output from a DVDO, because there's plenty of color resolution and the DVDO is already 4:2:2.
The new mCable is shaping up to be better for 3d stuff, so I have a feeling the Linker chained with another video processor will still be my favorite plug and play low lag 4k scaling solution. Also, the Linker doesn't add ringing or soften the output.
None of this will matter much to most people soon, anyhow. The Extron HD-HD 4k has it all with a frame of lag. So, the HDFury 4k scalers are probably only for people that can't let go of their DVDO and own a display that can't scale 1080p properly.

Any reason to expect HD-HD 4Ks becoming cheaper soon? The non-4K HD-HD works phenomenally, I have really high expectations for the 4k, if only I could afford one.

It's already priced in an affordable range for their target market and it handles the current standard (4k@60Hz 4:4:4 with optional frame lock/frame rate conversion).
Probably won't hit the used market in significant numbers (or reasonable prices) until there's a compelling reason to upgrade.
Mind you, the HD-HD 4k isn't the only good 4k video scaler. There are more ambitious units out there from other manufacturers that will also eventually hit the market. Maybe one of those will also offer really good deinterlacing, because Extron doesn't have it. Regardless, almost all the really interesting new units have uncompressed color.

Re: Questions that do not deserve a thread
I'm looking to feed 480p from my Dreamcast to my Samsung plasma display, and I'm curious what my best option is. I'm using a SCART cable from retro access and I have both a Framemeister and Shinybow SCART to component transcoder. My plasma has analog component inputs, so I'm wondering if it's better to go SCART>Shinybow>component in(analog) or SCART>Framemeister>HDMI in(digital)? Thanks in advance.
