--- Quote from: NickG on August 23, 2008, 09:49:08 am ---Yeah, but then the game would be sideways, too, wouldn't it? It is the real PCB so the scanlines should be vertical; as should be the monitor. --- End quote --- That's what I mean, I don't remember seeing, and didn't recently see on original machines, vertical scanlines on vertically oriented games...although in some old videos of games up-close, they do seem vertical. ?? --- Quote ---BTW, I think that's actually the shadow mask density creating the lines in those pictures, Ummon. The scan is still normal raster, you can tell by the refresh. --- End quote --- Refresh? You mean, if I were watching it myself vs looking at the picture in the thread? --- Quote from: FrizzleFried on August 23, 2008, 02:44:50 pm ---You do realize that a monitor doesn't care what orientation it is installed in, it will always scan from top to bottom as if it was in the horizontal position. If it's set vertically, lets say twisted 90 degrees counter clockwise while looking at the screen, the scan lines will run from left to right...if it's twisted 90 degrees clockwise it will scan from right to left. --- End quote --- Um, maybe you mean it the reverse? And, yeah, that's what all my raster monitors - arcade and pc - do. |

Ok I gotta admit I don't really know for sure what I am talking about, and that the thing I was referring to as "the refresh" may be the same thing Xiaou2 is reffering to as the scanline. I was talking about the dark vertical bar area which is parallel to the ladders and between Donkey Kong and the Lady in the first pic and along the rightmost ladders in the second pic. Here is a more dramatic image of what I was picking out in your linked post; taken with a faster camera. If FrizzleFried is correct (and if I have understood him correctly) then what I was looking at is something else entirely. Does this mean that for vertical game's PCBs you have to switch the x and y deflection coils or use a special chassis entirely? |

Look at the same thread, but down at CornishHen's pics. You'll see the "refresh" darkening is VERTICAL (as it should be) |

Y'know, I've never really known exactly what scanlines are or their general importance to some people, so this is a bit alien to me. Anyone? |

Anyone? --- End quote --- I know for me, I watched a lot of television close to the screen and would see the pixels, scanlines, and whatnot. I would really notice them. On an old monitor, when the screen was blurry you'd really notice that the pixels and lines blur together and look very bad. A sign of a quality monitor and/or new game would be very crisp, clear, well defined scanlines. I'm sure scanlines as I remember them never existed, but rather are the sum of my collective memories of pixels, scanlines, masks, and matrices. Most games just don't look right without some emulation of scanlines to me. |
