Dell docking stations compatability with new Latitude e7440

Hi AlexRau,

Thanks for the post! The Dell / Manufacturers part numbers can differ for matching hardware on Dell.com. Variables such as region and manufacturer can affect the part numbers listed and even if two components are of the exact same hardware specifications and share the same compatibilities, the part numbers listed on Dell.com may be different from one page to the next.

In order to confirm Compatibility of the hardware prior to making a purchase, make sure to check the ‘Compatibility’ tab on the sales site, the link below for example is listed as compatible with the Latitude E7440 system.

 Thanks,

Thanks for the speedy reply. Indeed, I always check the laptop models that are listed as compatible in the seller's product description, but many sellers do not list the new e7x40 laptops whereas others do, which raises uncertainty about who is correct. Again, when I say this, I am referring to products with exactly the same features and product title but listed  with a Manufucturer P/N different from the one on Dell's website. I assume this is because most of these stations were released prior to the release of the e7x40 and only a few sellers were wise or fortunate enough to try the docking stations with the new laptop - and they figured it works. So what I'm getting at is there appears to be a lack of awareness as to which products (i.e. which M-P/N) are compatible with the e7x40. I have spoken to Dell reps twice about this, and gave them a few of the M-P/N listed in my previous post; one of them said he could see that the inventory is available but that there is no description available; another flat out denied that there was any such inventory within their system. As I dont want to waste any more time speaking to Dell on the phone, I was hoping to migrate my question to the forum so that a proper investigation can be done into the range of M-P/Ns that support the e7x40. After all, who other than Dell, should know what works and what doesn't? Not to mention the fact that I've seen in some offical demonstrations of the e7x40 mention of "...and it works with your traditional docking station", implying that possibly pre-release docking station models should work.

This means you should have functionality when using a combination of any E**** system to an E-port docking station.

Thank you, this is the essential piece of info I wanted to hear. It should mean that regardless of what the Manufacturing number is, if the product is listed as the "E-port II with USB 3.0" and has the same specifications as the one listed on Dell's website, then it should fully work with the E7x40 series laptops with USB 3.0 ports. I would guess then that even the slighly older USB 2.0-only stations should work.

Just wanted to update this post (for future reference) to confirm that docks with different p/n will work. The one I received has p/n 6TJ57.

Am I right in thinking that the e-port plus docking station is compatible with the E7440?

Keeping in mind that I'm not a Dell rep, my personal understanding is that the new 7000 series laptops are compatible with all e-port docking stations including stations that were released prior to the 7000 series release date, so Yes.

Yeah, like the previous Dell rep said any E***** laptops should be compatible with E-port docks. I dont know why Dell doesnt list the E7440 E7240. Maybe they're too lazy to update the list....?

Is there a difference between PR03X and XX6F0? My understanding that PR03X is the older version, and XX6F0 is the version with DisplayPort 1.2 which I need.

My company ordered recertified XX6F0 from Dell, but we got PR03X instead. I'm unable to get DisplayPort daisy chaining working with it. I'm very confused by this.
