I'm thinking of turning one of my older PCs into a retro

Bump. Id like to know the answer to this too

may get better results with an original xbox running coinops.

That s-video connector is just a connector. It's the signal that matters. These cards output minimum 31Khz, and usually a higher minimum of 60Khz. If you can find a modern video card with s-video out that can output at 15Khz, then go for it. But unless you get a video card specifically made to output to consumer TVs or arcade monitors, it ain't gonna happen. If you want to go PC to CRT TV, then you really need to go RGB. Anything else would just require another converter/adapter.

>>3631987
Sounds like a solid plan. The only issues you should have would be relating to worn out parts, cooling issues, noise, limited processing power, and a big clunky ATX box being an eyesore if you've got it in a living room. S-video was pretty damn common on old video cards, particularly if they were fairly good.

You might have a few other oddities to factor in depending on whether you go with windows, linux or reactOS. As a bonus, you can add in a few PC games, particularly ones that use non-flight joysticks and the like.

>>3632012
The S-video and composite ports on video cards were always referred to specifically as "TV-out". Why else would they be there? It wasn't some opportunistic hacky spin on VGA. Early 3d-cards were said to have flaky TV out, and back then it was something of a special feature, naturally because of the extra circuitry that had to be included.

forgive the simple question but would using a cry computer monitor via vga be better than say using a lcd monitor via hdmi in terms of input lag? I emulate on my pc and am considering getting a crt pc monitor if I can find any

>>3632040
crt would absolutely be better, there is no input lag.

>>3632020
LCD TVs with S-Video and composite inputs. They can accept the higher frequency video just fine. Look, unless the videocard specifically outputs at 15Khz, it won't work. If it does, then it's a card with specific TV compatible video out. Just having an s-video port isn't a guarantee.

>>3631987
The s-video output will be forced to 480i and will look like shit. You cannot get 240p from that port.

>>3632117
You can, it's all a matter of software.

>>3632040
CRT monitors were relatively heavy and long for their size (ie. diagonal inches). Cheap ones seem to have deficiencies. Many, especially those cheepies, had only one VGA connection, and that tended to be stuck cable instead of a port, screwing you out of seamlessly connecting a fruitberry pi, dreamcast or DOS machine in addition to an emulation PC.

Aside from that, they were wonderful, comparing favourably to TVs.

/crt/ here. Sadly, the drivers for most if not all SVideo compatible VGA cards are not capable of outputting 240p. If you don't want to go full autismo and run RGB, you will probably get a more satisfying image from a VGA CRT displaying 640x480@60hz with a simple scanline filter

>>3632012
No, those ports do actually output 15khz. AT/AMD was the specialist in direct TV-outs on video cards.

That said it's invariably interlaced so no 240p or what have you.

>>3632105
Where did you hear of video cards equipped with such impractical S-video connectors operating at VGA timings? LCD TVs were not he norm when video out started becoming offered, and I never even saw a video card that came with a VGA to S-video cable, which I suspect they just might have been able to do if they sloppily half-implemented S-video and composite.

>>3632105
>They can accept the higher frequency video just fine
S-Video and Composite as a standard cannot be used for anything outside of standard definition 15khz video.

Those LCDs with S-Video and Composite connections are just upscaling that to their panel's native resolution. If you have a GPU with S-Video or Composite out, it is explicitly 15khz video. The GPU takes whatever resolution is being used and encode it into a 720x480(assuming NTSC) frame which is then output as a standard interlaced video signal to your display of choice.

>>3631987
>Will the image be displayed true/correctly on the CRT?
No. Everything will be scaled to 480i. It will be blurry as fuck and really flickery/jumpy.

Will this thing do what OP wants? I rember hearing about it 10 years ago when I was thinks of building a mame cabinet.

>>3632012
Most of what you said was wrong. Stop misinforming people.

>>3631987
That connector is not "s-video" on most cards, but an adapter that connects to a wire with composite/svideo. It will ONLY do 480i for what you are trying.

Your best bet is to get an older Radeon GPU that can be forced, with special drivers, into 240p output mode through dvi/vga. Then turning that dvi or vga output into whatever you want from there and plugging it into your CRT.

Radeon 4890 or 4870 have the tv-out port (if for some reason you still want the tv out port), and also have the ability to use the custom drivers to force 240p over dvi.

As far as lag or delay? None except if you buy cheap connectors from the dvi of the gpu. You are probably going to be spending $100 or so for a Audio Authority 9a60(or similar) to get your radeon 4xxx dvi port hooked up to your CRT.

Before anyone asks. DVI can go to VGA then to the 9a60 then to your component TV at 240p.

>>3632118
Please show us this software. No software currently, even emudriver or soft15k, can access that port.

>>3632312
>can access that port.
Maybe on some recent versions of Windows.

If you're an enthusiast then go for a RGB solution with "zero" loss of quality. There are custom graphics cards available on arcade oriented sides where the output is guaranteed to be compatible with an old TV(given it has RGB input via Scart or components). Ati's low grade (5450/6450) cards seem to be the perfect matches for such endeavours. I think the cards on arcade sites just have a customized bios. Or... just buy an old PC monitor if you're hesitant regarding unnecessary spendings.

>>3632012
Wrong. You can hook that connector straight up to a TV. I know because I've done it before.

Also, most old cards like that use a 7-pin s-video, and they can output at least component, but need a breakout cable (that was usually supplied with the card).

>>3632123
Why not just 320x240@120Hz?
That way you'll get natural scanlines.

>>3632309
*As long as it's the 4 pin mini-din as pictured, then it's strictly s-video.

More than 4 pins will need a breakout adapter.

>>3632494
You'll want to use black frame insertion to eliminate motion problems.

May as well up the horizontal to 3840 too. That helps to accommodate the widest range of resolutions without introducing scaling artifacts.

>>3632726
Not many monitors can go up to 3840x240@120Hz so I think making specific res for each system is better.
Also what kind of motion problems would black frame insertion fix?

>>3632735
Yes they can. Easily. Lrn2hsync.

You want to preserve the original frame rate as best you can otherwise there's going to be largely uncontrolled interpolation going on which is not a good thing.

>>3632776
So yeah, I managed to get the modeline working, but black frame insertion isn't working as intended.
I just see the black flickering and increasing Vsync swap interval just makes the game choppier.

>>3632105
The fuck are you talking about? I ran S video on many CRTs with my old-ass Radeon X300 no problem

there are low-profile cards with S-video out. there are also quite small mini-atx cases that don't look half bad

>>3633312
>nothing mechanical in a graphics card

Electronics can get worn out just as well. Electrolytic caps get used up, electromigration slowly erodes chips, etc.

>>3633312
>nothing mechanical in a graphics card
Capacitors! Also, the thermal goop could theoretically loose proper consistency.

Of course, the capacitors on the card aren't likely to be particularly strained ones, but then, that card sure as hell isn't the only component involved.
>a passively cooled card should suffice
AGAIN, there are other components. (and of the cards at hand, the one that's passively cooled by default may not be the card of choice.)
>don't need a lot for retro games
EMULATION. Native retro apps was a suggestion thrown in.
>also quite small mini-atx
And this is where the noise issue can become a very serious challenge!

How old are you talking? A really old box is going to need really old emulators, and those emulators are going to be buggy inaccurate pieces of shit. Your old shit is also probably going to be power hungry as fuck compared to something new. Not worth it.

Just use HDMI instead of some dumb roundabout method when HDMI works just fine

>>3634428

>but,but,but, just do the fucking NORMAL kinda thing, not the other thing that's the kind of thing a FREAK would be doing!

>>3633316

Holy shit, /vr/ trying to be smart.

>hurr muh capacitors
Not using capacitors kills them quicker than using them, pleb
Shitty quality capacitors expand and are easily noticeable and exchangeable even without a multimeter.

>>3634428
YES! Let's introduce lag from digital to analog conversation and HDMI framebuffer because fuck it, my CRT is S-video anyways and conversation boxes exist.

>>3632123
Yes they can, you manually enter the resolution, works on any Radeon or Geforce.

>>3632012
>>3632105

Nope, they output 15Khz, all of them.
Get rekt noob.

>>3631987
>Plan to have it hooked up to a CRT via S-Video connector.
Why not just RGB with a scandoubler/flickerfixer?

>>3636239
There just so happened to be a wave of lousy capacitors with just this type of vr gear. When companies decided to save money by switching to cheap Taiwanese suppliers like Luxom and Rulycon. And this was at that time before some Taiwanese companies upped their manufacturing tolerances to Japanese standards.

I'm not trying anything, I'm quite familiar with power feeding parts. In fact, I've seen a pentium one with a solid state / surface mounted capacitor, it happened to be a Dell, it's a rather awkward that dell seems to be rather good on the PSU side.

>>3631987
The setup will work. I've done it many times. The screen won't lag. The image will be displayed as true/correctly as your emulator and display settings allow. This can range from perfect to shit. Cards designed specifically for what you want to do are still made today. Those would be the "last known 'good' " ones. Older cards can be better and cheaper but may be harder to find.

>>3631987

Just do 640 x 480 VGA monitor with software scanlines.

Getting perfect 240p output is quite a journey and you still might end up needing to use some 7400 series stuff at the end.

I have done plenty research on 15kh cards.

The most powerful appears to be the Radeon HD 4890 with an s-video output.

There was a card based off the Radeon HD 3650 called the ATI Wonder HD, which was a media center graphics and capture card. There was an expansion accessory that allowed it to output component (YPbPr). The card is rare and the component accessory is nearly unheard of, so don't get your hopes up.

>>3636797
>software scanlines
you can get natural scanlines at 240@120hz

>>3637413
svideo.com has a wide range of ATI to component adaptor cables.

One of those and CRU would surely get the results OP is after...unless I'm missing something?

>>3637929
Obviously a card with 7 or 9 pin VIVO output would be needed, rather than the 4 pin in OP pic.

>>3631987
The S-Video output will be ok, but not great. It'll force anything you output into resampeld 480i.

Better would be to google crt_emudriver and then either get an RGB monitor, or second to that, a RGB>YPbPr (component) or S-Video transcoder, depending on your CRT. That will give you a pretty clean signal.

>>3636787
>vr gear
Those cards are not /vr/ you idiot.

>>3631987
i know that some radeon cards from x300 era had s-video. they ought to be decent for emulating older systems.

480i only m8.

The TV-out on these things is useless for anything retro.

>>3638716
If it's something great for playing games from 1999, it's /vr/ gear!
