How To Enable Daisy-Chaining On The Dell U2414H Monitor. I’m just going to quickly show you how to enable DisplayPort 1.2 and configure daisy-chaining with the Dell U2414H monitor. This will allow us to run two monitors with only one of them plugged into the computer.
First off DisplayPort 1.2 is required to support daisy-chaining, it will not work with older versions. By default this particular monitor ships with DisplayPort 1.1a enabled, so we need to change this first. If you do not enable DisplayPort 1.2 and just plug the second monitor in, both monitors will only run in mirrored mode and show the same image.
Simply press any of the leftmost four buttons on the front of the display to bring up the options, and select the menu icon. From here go down to Display Settings and then select the right arrow button to modify them. Go down to DisplayPort 1.2 and select it with the right arrow button.
Simply change it from disabled to enabled. When you do this you’ll get a warning asking you to check that your graphics card supports DisplayPort multi-stream transport, aka daisy chaining. I’m using a 5 year old AMD 6990 graphics card and it has DisplayPort 1.2 support so it’s been around for awhile now. You’ll be advised that if it doesn’t support DisplayPort 1.2 and you enable this setting you may get a monitor with a blank screen.
If you do end up with a blank screen, just highlight either the DisplayPort or Mini DisplayPort in the Input Sources and then hold the tick button for approximately 8 seconds. You’ll now be able to disable DisplayPort 1.2 if required. We only need to enable DisplayPort 1.2 on the monitor that is connected to the graphics card, the secondary monitor does not need it enabled – my second screen still has it disabled and it’s been working fine.
I’m using the included cable that came with the monitor, a DisplayPort to Mini DisplayPort cable. First I plug the DisplayPort end of the cable into the primary monitors DisplayPort out port. The other Mini DisplayPort end goes into my secondary monitor’s Mini DisplayPort. For me the monitor was instantly recognized, however you may need to go into the display settings of your particular operating system in order to configure how it should display.
Unfortunately I don’t have any additional monitors to test setting this up with a third screen. I’ve also tried to get this to work with the Thunderbolt ports on my MacBook pro as this apparently supports DisplayPort 1.2 as well, however both of the external monitors mirror each other and act as a single display.
From my research this seems to be an operating system specific issue, people have reported that it works when they boot into Windows. I’ve got two mini DisplayPorts available so I can always just run one monitor off each. That’s all there is to it, you should now be able to enable DisplayPort 1.2 and setup daisy chaining with dual monitors.
