Regardless, "phosphor lag" does not cause the pixel to smear horizontally as Tom suggested.

Phosphor lag is entrenched in FCC rules. There is no pixel to pixel black to white transition. It takes several pixels to cover a complete transition. Color to color is just as bad. Similarly, there is no true white or black. Blue, green, or red for that matter. Range is limited to 15 to 240, out of 1 to 254. I can understand why to restrict 0 and 255. CRTs are rapidly being scrapped, but we are still saddled with their legacy.At least for broadcast standards, blurred edges will be here until the FCC stops caring about CRTs.Rich
