Atari Emulation of CRT Effects On LCDs
An anonymous reader writes "A group at Georgia Institute of Technology has developed a fun little open source program to emulate the CRT effects to make old Atari games look like they originally did when played on modern LCD's and digital displays. Things like color bleed, ghosting, noise, etc. are reproduced to give a more realistic appearance."
And does their program eliminate motion blur and the poor contrast of LCD to make it looks like a CRT?
No but the 21st Century did.

Because old systems counted on it. They were designed around working on low rez NTSC displays. You find that the color bleed and fringing and such helped smooth out the image and make it more natural. When you display it on a modern high resolution LCD it looks extremely blocky. So you emulate the problems with the older technology and you get a better looking picture for it.

It is beyond me why anybody would want to make something look like it did, instead of how it should look.
But this IS how it "should look". It was designed for that display. People want it to look like it originally did for the same reason that people like muscle cars, vinyl records (complete with the hiss and wow and flutter that they try so hard to eliminate), valve amplifiers. It's because sometimes the inaccuracies in equipment change the signal for the better, and people like that.

CRTs have better black levels and better colors. On the other hand, they have fussy geometry adjustments (and you can never get them as perfect as an LCD), moiré patterns, and are generally much fuzzier than LCDs.
My LCD provides a sharp, high-resolution image with low power consumption in a small package at a low price. All of those factors (sharpness, resolution, power cosumption, size, price) matter more to me than the areas where CRTs continue to lead (color reproduction, black level).
