No, the signal indicates whether a given field is for even or odd scanlines. I used plenty of computers and CRTs around that time and not one incorrectly displayed progressive as interlaced.

- TazeTSchnitzel 10y agoTo clarify, I'm talking about CRT TVs, not computer monitors. The latter aren't (usually†) interlaced. †There's some interesting exceptions!
- ghusbands 10y agoI'm talking about televisions and similar. You are still simply wrong. Nearly all of the 8-bit and 16-bit consoles and computers that output to CRT default to non-interlaced, without the TV alternating fields. Look at other responses in this thread to see how interlacing used to be achieved and the flexibility it had.
- TazeTSchnitzel 10y agoAh, I see now. Your comment about the half-length scanline made me understand.
- boomlinde 10y agoNeither are most CRT TVs, if you keep feeding them the odd/even field repeatedly. I keep CRT TVs and monitors at home and can easily verify this. The effect is usually dark gaps between the lines or doubled lines (where the corresponding field would otherwise have been drawn). Doubled lines, as in the same as the previous line of the same field, not from the previous field. It's not a particularly obscure subject or uncommon trick, so I don't see why you would keep insisting that it isn't so when any source that possibly could have proven you right, if you were, will prove you wrong.
- TazeTSchnitzel 10y agoI think I misunderstood the responses I got at first, and I couldn't easily find a source. Now that I do understand, it's quite interesting.
