s-vid output to rgb scart?

[ryu]

i recently noticed that my computer's graphics card has s-vid output. since i own a pair of pvm monitors, i've been wondering if i could get some use out of that.

what would be the best way to go from there into a scart input? i know old pal consoles had these scart adapters to use, but i'm pretty sure they convert the video into composite vid.

looking at wikipedia

This is a non standard 7-pin mini-DIN connectors (this variant is called "7P"). These are used on computer equipment (PCs). A 7-pin socket accepts and is pin compatible with standard 4-pin S-Video plug.[6] The three extra sockets may be used to supply composite (CVBS) or an RGB or YPbPr video signal

it seems i could even get rgb out of this?

RGB is RGB
SVIDEO is SVIDEO

You can't get RGB from svideo.

It's possible to accept svideo via SCART, but the SCART input needs to be able to accept it.... Not all can.

[ryu]

alright, guess i'll just play around with this and see if it works

Forget using the S-Video out, you don't benefit anything using it. If you have a vga card, and a sony pvm you can get some "vga to BNC" cable and conect your PC to the pvm. Before doing it you should boot the PC in a vga monitor and change the resolution to a lower resolution using a program like Soft-15khz, or CRT EmuDriver. If your sony pvm in particular don't have bnc inputs, or you prefer to use scart rgb you can make a VGA to scart cable, or buy a made one, on try the new UMSA - Ultimate SCART Adapter from the ArcadeForge.

PS: Thanks to Fudoh for correcting me

Pardon me, but if you connect a PC to a PVM *without using Soft15khz* you'll permanently damage your PVM (and won't get a proper picture anyway). How can you recommend this ?

[Overkill]

My God, you're right! I just forgot the signal is coming in 31Khz! And even with the soft15Khz you can't boot the PC connected to the PVM. The low 15Khz resolutions will only start after the windows boot. My fault, gonna edit the post. The only method without risk of damaging the PVM will be a ArcadeVga, or a compatible vga card flashed with a ArcadeVga firmware.

Sure, but a mini-DIN socket is not always S-Video. The video card on my last desktop (ATi Radeon X800XL) provided TV-out via a DIN socket, and if you used an S-Video cable you'd get an S-Video signal, or you could use an included breakout cable for Component output.

You've lost me!

I never said his mini-din was s-video.... I can only assume it is as he said it is.

[fagin]

And even with the soft15Khz you can't boot the PC connected to the PVM.

I'm not sure if this is 100% for all OS and gfx set-ups now.....

Under Windows7 with my gfx card and soft15, which doesnt actually work properly, booted through the windows splash screens fine connected to Sony CRT.

All I did was ensure the default res was 640x480 and it was as if Windows 7 / gfx drivers changed the output to interlaced - automatically.... weird.

[ryu]

to be honest i was hoping for my pc to be able to output 480i through the mini-din connector. my pvms don't have bnc ports.

i didn't know there's solutions for outputting sd resolutions through vga. thanks for those infos - the soft 15 khz & umsa solution seems pretty nice, just too bad i'm using windows 7 on my desktop.

i'll ask my brother (who likes hoarding spare pcs and parts) if he can cook me something up. otherwise i'll just see if i can get a sd resolution out of the s-video output.

i wasn't sure when i made the thread, but assumed it since that quote said it was used for pcs. but yeah, my vga's got a mini-din connector.

Why is Windows 7 a problem - it shouldn't be.

i checked their forums and it said windows vista wasn't supported, so i assumed it might not work. i also imagine it to be a pain to have to clear out the desktop each time i'd want to use 240p output. i don't think that would show a lot of icons.
my brother gave me a pc with win xp for free anyways, so this won't be a problem no matter what.

[matrigs]

i can't get soft15khz to work with lower resolutions than 640x480 in windows 7.

windows xp works like a charm though.

and this on my desktop with a nvidia card and a laptop with a radeon so it's rather not hardware dependent.

[fagin]

I can get lower than VGA in Windows7 and soft15.... I just can't enable 15khz on my video card properly.

Win7 64bit here.

are you using any software to change the res like quickres ? or are you able to make some custom resolutions in windows. i can't.

also - are you using the soft15khz dongle ?

[ryu]

the dongle's only used for geforce 8x, 9x and gtx cards.

i got everything running on my second computer. however, when i set the resolution to 240p my monitor stopped getting a signal. any chance that my vga monitor just doesn't support 15khz? i don't have any ways to test this on an actual 15khz monitor yet.

[matrigs]

lcd's don't work with 15 khz.

at least none that i know.

[ryu]

ah, alright. glad to hear that

Quickres only and no dongle.

They can and there are some that do, but not that many.

I can confirm that Acer P244W will work with 15 and 25khz, in addition to any other resolution up to 1080p on it's VGA port. It's a shame they're older and a bitch to find now.

You sure it works with 15khz... Specs in manual only mention the lowest being 25khz

I've put 15khz into it. It works, with the exception of Gradius IV, but Gradius IV puts out a pretty whack 15khz picture, so I blame the source and not the target.

[fagin]

[ryu]

alright - i recently got the equipment to hook it up to a low res monitor, but i want to avoid accidentally blowing it. is 15khz short for 15.6khz? because that seems to be what my soft15khz pc is outputting at 240p.

also, even with a desktop resolution of 240p, programs can still exceed that resolution when used in fullscreen mode, right?

[fagin]

Don't worry - soft15khz will output the correct khz when set! You have nothing to worry about.

Of course programs can exceed the 320x240p desktop resolutions - but it won't hurt anything.

[ryu]

ah, what i meant by exceeding the desktop resolution wasn't that. i meant if programs could force a higher resolution output over the desktop resolution.

[fagin]

The desktop area is nothing to do with the resolution your video card is outputting.

[ryu]

ah yeah. i tried it anyways and it worked fine. thanks!

[ryu]

should have mentioned i have so far only tried this with one game. i'm still dubious about using emulators on it.

for example using winkawaks, it needs to be set to a fullscreen resolution higher than 15khz for blazing star to run. is this nothing to worry about either?
