Does anyone have any links explaining the difference in technical terms from 2048 to 1024. Trying to explain to someone but they want more info. Jr's site just talks about the 2048 having a faster latency time but was looking for more. Did a search but didn't really come up with what I was looking for. Thanks

Latency and resolution are two different things.

In short, with a digital system (2.4 or pcm) your stick throw is divided into steps.

With a 512 (the first pcm systems) there were 512 steps from full up to full down, if the stick was between those steps the servo didn't move till it got to the next one.

1024 uses an additional bit to encode the stick position so now you have 1024 steps so the "dead areas" between steps are smaller.

2048 adds yet another bit so the steps are even smaller.

thanks for the info. I meant resolution. Trying to explain to someone his 12x 2048 has nothing to do with the screen. He's thinking in terms of a TV.
