In the nineties and noughties, in addition to regular monitor output, PC graphics cards sometimes had output towards analog TV input.
Fiddling hints:
- PAL versus NTSC matters, and more importantly, drivers can be stupid and stubborn about using their preference over yours
- Refresh rate matters - usually tied to the mode you set, not always only to that.
- I've seen the monitor's refresh have effect on the TV out('s refresh?)
- I've seen my card go to 0 saturation. Don't assume that seeing a grayscale image must be the cabling, the wrong PAL/NTSC variant, or such.
- Some TVs adapt to signal when changing input/channel - and not always while you're fiddling on the computer side. It may help to switch the TV to something else and back.
- There may be a deinterlacing setting. Using it means things look less twitchy, at the cost of a little blurriness. Since you probably want to set a larger font size for SDTV resolutions, a moderate setting is usually worth it.
