The hp 1740 display has vga and dvi in ports.
The iMac has 1 USB port free.
Is there a dvi to usb cable and/or adaptor configuration available, and if so, would the usb allow enough signal to the display's dvi port to drive the small display?
forget about usb it does not carry video only pure digital serial data
use an adaptor from thunderbolt2 to dvi
I use that from my mac mini 2012 to a monitor with dvi

You need a mini display port to whatever input the external display has. For example if the display has DVI get a Mini DisplayPort to DVI adapter and connect. As stated you cannot connect using a USB cable!!!!
you can use the usb port for something though
if you can find an external usb video card that has macos driver for the macos version like this Amazon.com: StarTech USB 3.0 to HDMI/DVI External Video Card Monitor Adapter with Graphics Cards (USB32HDE) - Black: Computers & Accessories
Your 2012 has a Thunderbolt port which is identical in size to a Minidisplay port which, please do as instructed. For the 3rd and final time USB WILL NOT WORK.
You don't connect external display using a USB port. Without knowing which iMac you have (they have been made for over 20 years!!!) we cannot tell you the adapter you will need. If you are unsure, check in About this Mac which can be found by clicking the symbol in the upper left of the display. Tell use the size and model year of the iMac then we can direct you.
I did tell u in subject- old iMac (late 2012).
my iMac display is bad.
iMac works otherwise.
I connected a large external display, works fine.
if I want to connect a second small display, the hp 1740, there is only 1 USB port remaining on iMac.
is this possible using a dvi to usb cable and/or adaptor configuration, and if so, would the usb allow enough signal to the display's dvi port to drive the small display?
iMac late 2012 27" display doesn't have a mini display port, right?
If so, its occupied by something critical.
if not, then I dont suppose there is a USB to mini port adaptor?
OK thank you!
Have to get another Mac soon anyway.
Ok Ill try that. Thank you!
Have to out a backup drive to open a thunderbolt port.
OK great Tbolt port could work...
Thanks
