> I foremost think people should have the freedom to bust their nut over resolutions if it makes them cum but personally, I don't see any difference visually in using S-Video to cheap CRT tv with recent mames and a pcb in a real cabinet. Slightly different scanline positions? Is Sherlock Holmes playing with a magnifying glass? It looks the same. In many cases it looks more vibrant because you have color controls on the tv and when you're in an arcade you get what you get.

> If scart can slice another frame of input lag over S-Video (can it?) then cool but mame already adds some either way so it's not 100% accurate either way you look at it.

It's 'not having to slice'. Things come out as they were determined and stay that way. There's a comprehensive explanation over at the B by MonMotha about different display standards and their color spaces.

S-vid on a CRT is like turning up the brightness and contrast all the way and it's stuck that way. Also, depending on the display adapter's scaling alrgorith (ideally it shouldn't, but....), image quality is perhaps 80%, but doesn't look shit if you're watching Peanuts or something. Terrible for video games, especially blank background games. Looks like heat waves inside the tube.

An LCD already has that kind of brightnes (and hence contrast - lack of true blacks) issue due to the backlighting. I haven't seen S-vid on one, so I can't say about the heat waves bit. Accoring to MonMotha, if it's done right, and the color space is correct, S-video can compete with component.

I haven't run MAME beyond SXGA on a decent LCD, so I can't say the possible image quality. But in my experience, PCB+CRT equals the image has a reality of its own; like they're sort of Flatland entities with a very, but perceptibly, thin depth (we're talking especially about golden age games). Pre-video-re-write MAME had more of that across games, and the scanline effects helped with that. Things are more complex now, so it doesn't come as easy; it looks to me like there's a 'light' overlay on the display image.

Most of all: in my recent Starfighter's trip I noted (and noted in my last trip), there's an inexplicable difference in how the image 'behaves' with PCB+19"CRT - the objects are the most 'real', like looking into a window rather than at a screen - which may be related to how the phosphors illunimate, versus a larger, especially newer design, CRT. Objects just seem to move faster on a newer CRT design, verus this sort of measured and fluid pace on an older one. I wish I had a decent camera to capture it. Maybe. Could lead to a revolution in game display.

Scifi frauds. SF illuminates.
