CRT vs LCD...

Its all a matter of taste. I personally think the classics shine even better on modern LCD's. Leave all the crap OpenGL scaling turned off, and enjoy that marvellous blocky graphics to the max! Come and have a look at my wide gamut LCD with DK on it. It's fantastic! Atari 2600 games: breathtaking! My game gear games (which were shown on the crappiest of the crappiest colour LCD back then): astonishing graphics! It's like all the games get that mystical Madonna being 50 years old look. Even prettier then you remember them from the past. The game-pixel-art flourishes like it has never flourished before!

What if the current LCD was available in 1970, and computing power was like it was in 1970? Atari would have put LCD in the cabs then (off course, the image computing power of an LCD screen is way more powerful then any system made before 1990). They just bought the best technology available back then.

Whether it was intentional or not, the CRT design is the best upscaler that I know of. :)  I wish all LCDs had a decent emulation of CRT video built in. :)

Those long decays are really something out of history (B&W arcades). This is a pretty regular RBG-CRT figure:

This typical RGB phosphor looses 90% of its brightness already 1ms after it is lit. In 2ms it looks black completely. The next frame takes 17ms, so the persistence is not really helping reduction of the flickr in this case.

Here you see a really fast and a really slow one (the last one would probably give a classic Pong look):


GaryMcT:

That explains the apparent flickering.  It's weird that I see it when I first start up a game, but that I stop noticing it when I start playing.  I suppose it's one of the few things that I'm not totally anal about with audio and video. :)  Audio latency is driving me batty.  I have a high quality/low-latency audio device from doing music stuff that I'm going to try to see if I can get the Mame latency down to the lowest setting, which will probably be fine for me.  Tearing drives me nuts too.  I'm planning on trying svgalib/Linux to get the resolution and refresh rate for the games that I care about (it's a pain in the butt in Windows), but I haven't gotten around to it yet.  I've been tempted to modify Mame in Windows to be smarter about dropping frames where appropriate when vsyncing so that things don't go bad.  It knows how to drop frames if the CPU is behind, but it doesn't know how to drop frame if the GPU is behind from what I can tell.  That's the cause of the audio badness with vsync.  I don't like the cabmame solution of retiming the audio. . .I'd rather drop frames of video occasionally.

Downloading PoweDVD 9 Ultra now. It has it. Thanks.

Update: Just tried it. Wow, not quite as weird as the 120hz TVs, but still pretty weird.
