One cool thing you can try with a pc crt is 31.5 khz modes. Several old CRT monitors can handle this. I have two Sony Trinitrons that support this mode. In advancemame I have set this mode and applied scan lines and the difference between this mode and 15.75 khz modes on my other monitor are minimal. The only difference I can tell is that the that the 31.5 khz mode is a little darker and duller with the fake scanlines than the real 15.75 khz resolution. But it still looks very good. I think it actually looks better to just leave them off and live with the slightly pixelated looking 31.5 khz mode, as the brightness is very good. |

Perhaps if I did some of thing discussed in this thread I would get the same results. I think maybe advancemame is doubling the resolution to exactly 672x480 instead of 640x480. |

The biggest issue with making a PC/Lcd monitor look like an arcade monitor is not the lines. Its the color bleed and mixing and slight blur & glow. What really needs to be done... is to use software to simulate the pixel color mixing/bleeding on the fly. Now that we have dual (and quad..) core pcs... it would be great to use that extra processor to do the image output. OR Maybe Randy could whip up a hardware version... which then would take a vga input.. tweak it, then output it to the monitor. |
