[NAME]  Happy to help!  Don't feel too bad about not knowing these things.  There are a lot of choices and the technical differences aren't always clear.  The E-Port dock will work fine with an E7470 as well.  One optional part you can look into is the "spacer" for that dock.  Essentially, the early E Series systems had the underside docking connector close to the center of the system, so that when you aligned that connector with the connector on the dock itself, the rearmost few inches of the laptop would close the gap to the main raised horizontal portion of the dock.  On the newer E Series models like yours, the underside dock connector was moved to the rear edge of the system.  The result is that when you dock newer systems on the E-Port dock, there's a gap of a few inches between the rear edge of the system and the main part of the dock.  The optional spacer bridges that gap.  The main benefit is that it makes it a bit easier to quickly position those newer systems on the dock correctly, but it's not technically required.  Here is a link to the spacer if you're in the US.  Good luck!
Hi all,   I am sorry to trouble you with this as this was probably a subject discussed so many times. I have a 5470 and was planning to get a D6000 for office use for a 49 inch ultra wide monitor.  As the native resolution of the laptop is not that high, I was reading around but I am not an expert and I got even more confused. Can someone please let me know if I connect the D6000 on USB (not C, as 5470 doesn't have one) will it output on a single connection a resolution of 5120 x 1440, and what refresh rate would that be at? Thank you in advance for your time to reply to my question. Kind regards, Axytigana
