No they don't. I'm talking new hybrid fruit we haven't seen yet, you thinking apples
Pretty much everyone has what Dell has, all our monitors have them, none are used. These are the last Dell 3 monitors reviewed by TFTcentral.
Dell UP2718Q - "There are also 4x USB 3.0 ports, 2 located
on the back of the screen with the video connections,
and 2 on the left hand side "
Dell Alienware AW3418DW - "There are also 4x USB 3.0 ports, 2
located on the back of the screen with the video connections and
2 on the bottom edge."
Dell U2717D - There are also 2x USB 3.0 ports
located on the underside of the screen with the video connections and 2x port
on the bottom left hand edge of the screen for easy access,
None of them have USB hub built into the
monitor ***stand*** let alone one independently powered.
Not on back or on side of the screen as described for all the dell's above ... but built into the structural vertical support arm that holds up the monitor screen:
Picture this 7 port hub model:

Now imagine it in the bottom 4 inches of that vertical rectangular part going up from the flat base sitting on your desk which allows you to adjust screen height. In this manner ...
a) when one wants to temporarily plug in and charge their wireless KB, Mouse, Headphones, cell phones, game controllers, whatever to charge the batteries ... the user don't have to blindly search for the ports . You don't plug them into the "screen", you plug them into the "stand" where you can much more easily see them. For example, when gaming and the headphones start beeping telling you 5 minutes left in battery, your are not interrupting the game play swiveling the screen to find the ports on back of the screen.
b) You don't have the issue of having the battery charging load, blow the USB header. Have had systems brought in where folks over loaded the on board USB and I even blew out the USB header on my lappie once by plugging in a laptop cooler.
I have a 7 port model like the one linked above, held upright against my monitor's vertical support with a rubber band. It's independently powered so no worries about how much load is put on it. It's also more convenient. Having ya monitor GFX card and power cables on the back is cool as it's a 1 time thing , twisting and turning the monitor to get the cables in .... but for wireless KBs, mice, headphones, phones, game controllers, ... whatever, fiddling around back is a cumbersome task.
Ideally it would be modular "plug in" thing so if it died could be easily replaced.
