Half of that is Greek to me. I'm nowhere near that level. |

I'll break it out to you: Arcade monitors have scanlines and a fluid picture because they have half the horizontal frequency of a regular VGA monitor. That is, the VGA has 31 khz and the arcade monitor has 15 khz. An RGB signal from ArcadeVGA, SuperNES, Saturn, is always 15 khz, the resolution usually is 320x240 non-interlaced (runs at 60 frames per second, the most recommended) or 640x480 interlaced (runs at 30 frames per second, avoid if possible for arcade games due to flicker). Now any Standart Definition CRT TV has 15 khz BUT your problem is: you can't input RGB because in North America there's no RGB connection. So what you have to do, is pick your RGB connection and a converter (not an adapter, there's a need to change the nature of the signal) to make it compatible with your TV. That would be the SCART RGB to YPrPb converter. A member in shmups system11 told me it would work and i'm investing toward this setup. Let's pick two cenarios: 1) SDTV + ArcadeVGA + RGB to YPrPb Neo-Geo (320x224) would run at 320x240 and at the correct frequency. It would have NATURAL scanlines. 2) LCD + regular VGA LCD are bad. The reason is: http://en.wikipedia.org/wiki/Fixed_pixel_display Fixed pixel displays are display technologies such as LCD and plasma that use an unfluctuating matrix of pixels with a set number of pixels in each row and column. With such displays, adjusting (scaling) to different aspect ratios because of different input signals requires complex processing. In contrast, the CRTs electronics architecture "paints" the screen with the required number of pixels horizontally and vertically. CRTs can be designed to more easily accommodate a wide range of inputs (VGA, XVGA, NTSC, HDTV, etc.). It means: LCD has only one resolution whereas a CRT has many. If you input something low-res at the LCD, it will have to scale it, and scaling is bad. Not only that, as you're drawing 15 khz games at 31 khz, your scanlines will be gone and you'll have to emulate them with MAME or with an external box like SLG3000. And by the way, don't dissamble a CRT monitor. They are VERY dangerous and could get you killed. |

I've been trying out MAME on my LCD with the various filters and it looks fine to me. In fact, I had a hi-res bezel around filtered Donkey Kong and it looked amazingly real. There is very little return for going with a CRT, IMO, unless you have an easily mountable one just sitting around or you REALLY know what you're doing (which I don't). Your last sentence is yet another reason I opted out of CRT. Bad enough I'm clueless . . I don't want to be clueless about something I need to handle like a land-mine. I just want to get this thing done and play arcade games. I'm happy with my choice. Paralysis by over-analysis is a hell of drug. |

That is the dumbest ever. And Fixed Pixel is no problem. The game we talk about here are in the 240x320 range. On a 1200x1600 it means all pixels are 5x5 pixels, on a fullHD 4x4. Who cares? The stunning pixel art will shine in all its blocky awesomeness. Throw in some wide gamut (which was never available in CRT) and these games shine like they have never done before. If wide gamut LCD's were standard in the eighties, they would not have used CRTs at all. It's a myth that scanlines and fuzzyness are ON PUROPSE. It's just a limit of tech at that time. The prove of this is the Atari 2600 and Colecovision. Way blockier than 480i was asking for. These consoles also had 4x4 pixel blocks! Second prove: have a kid watch an old game on the original cab and on my 27 inch PVA display. He will prefer the second. Kids are insensitive to nostalgia, and just pick the best, following the purest desires possible. They take the game for its game play and choose the best display to view it on! |
