S-Video to CRT TV problems

[Matt Stapleton]

Hi guys. I'm in the process of building a Mame cabinet, and for now I'd like to output the PC on to a CRT TV. The TV only has scart, so I've had to configure as such: S-Video>RCA (with scart adapter). However, the image I get is black and white, and I only get a distinguishable image on the post and 'starting windows' screen. After that, the image becomes wavy, distorted etc. Anyone have any tips on how to get colour and a clear output? Thank you

Perhaps you are confusing composite and component outputs

Keep in mind that NTSC is only 720x480 and PAL is only 720x576 so using a standard TV will give you quite poor resolution

Black and white, then wavy would indicate that the PC is attempting to output an NTSC signal via S-video, and the TV is looking for a PAL signal via SCart.

Is there any way I can change the output from NTSC to PAL? I can't access the PC whilst it's plugged in to the TV as I can't see anything on the screen, and when I have both the TV and Monitor (vga) it's not saying there's an svideo output in display settings. Sorry I've never really been good with displays - any help is much appreciated.

You might need a different adapter. One with switchable NTCS/PAL output.

Furthermore pal only supports 50 and 100Hz right. Your refresh rate on your adapter may be set wrong because this definitely isn't plug and play. Even if that fixed the wavy lines there is still the black and white...

Perhaps I should just go for a CRT monitor, would save a lot of hassle. Thanks anyway!

A monitor would far more suitable. Generally plug and play and higher resolution

You could give this a try?

A black and white image means the tv is not NTSC compatible. If you can see a black and white image then the tv is capable of displaying a 60hz image. It would just flicker if it didn't. You don't want to bother with an NTSC to pal converter. A good one is expensive and a cheap one will give you ghosting.

Svideo is only capable of either NTSC or Pal color so if the tv can't handle NTSC 3.58 then you need an rgb signal. Many pal only tv's are capable of a 60hz RGB signal through scart and you will get a full color image from arcade content.

Your best bet is a VGA to scart adapter which should let you output am rgb signal in 60hz in full color. Avoid composite and RCA inputs which would only work if the tv could handle NTSC 3.58. Most Sony tv's could, most other brands of pal tv couldn't. Some could only do NTSC 4.43 which would give you squashed graphics.

You just bought the wrong adapter.
