So I don't mean to undercut your guys' testing and progress - It's actually really good, thanks for it all - but I think we've come to the end of this debate now.
Let's address this:
People have always assumed CRTs are lagless. The one I used at least must have had a little because there is no LCDmonitor that is under like 9 ms according to the websites that quantify lag.
I'm going to frame everything for you:
For the game to render a frame, from input to render, the time is going to be 1-2 frames' worth, or somewhere around 25ms.
The amount of ms of lag being discussed (5-10) about must be considered relative to the amount of a ms in a single frame: 16.67ms.
CRTs, though virtually lagless (<1ms) in design and in the handling of the signal,
still apply post-processing, sometimes up to
a frame or more*.
In fact, I'd wager that most CRTs people play on can lag just as much or more as the LCDs being described here.
The very fact that you've shown that - with a proper
converter - Melee can be played as near lagless as a CRT can be, with the proper monitor, I think, signals the end of the debate, since the relative lag given by
many CRTs is roughly the same as the lag given by these newer monitors, with the given proper cables and conversion hardware.
In short, while there are still some CRTs that produce virtually lagless play, the debate between whether a monitor gives 5ms or 10ms is negligible to the bigger picture. Melee can be played on HDTVs now without lag.
The only small hurdle we might have now is a slight visual problem like the one Fizzi mentioned with the weird ghosting, as you can see in one of his screenshots.
I'm thinking a stickied thread should be made that just pithily gets to the point and describes how and where you can get the stuff to play Melee on an HDTV, while still referencing all the threads and posts that discuss the technical difficulties of defining this debate much further. I can compile a list of sources if you'd like, but I think until now, there's been bits of misinformation present in every thread or post about this topic thus far, and it seems it'd be nice if we could have a definitive say on what we know and don't know for sure. Except now, I think the "don't know" section has gotten negligibly small (minus the controller and console problem that's posed in the other thread, but for display purposes, it seems this discussion is coming to an end).
