Essential

I bought an essential to use on my PS4 a while back. Plugged it in, played, and have loved it ever since. I’m finally building a PC, and starting to dive into the more technical aspects of everything. One thing I can’t seem to get a for sure answer on, is about the out-of-box settings on the Deathadder Essential. I’ve looked at numerous forums and threads, and figured this would be the best place to look. Is the Essential’s default DPI the 6400 it advertises? All I can find is that 6400 is the max. I’ve read that other models have default DPIs of 1800? I also had the same question about the polling rate. If anyone can offer some insight here I would greatly appreciate it! I do not yet have a PC to download Synapse.
