Graphics card TV out notes

✎ This article/section is a stub — some half-sorted notes, not necessarily checked, not necessarily correct. Feel free to ignore, or tell me about it.

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.
