I would like to connect my television to my laptop using a video port in the docking station. The ports from which I can choose are depicted in the following photo:

I'm already using the top row of ports to connect two external monitors. I do not want to use the VGA port. I'd like to use one of the ports in the second row to connect my television. I'm assuming those are some form of DVI port. I'd like to find a compatible cable, but I don't know what type of port those are.

I see those connecter for monitors (and have a few in the basement). You need to get a cable with that termination on one end and then VGA on the other to connect to your TV

I'll need a cable with whatever connector is compatible with the docking station's port on one end, and HDMI on the other end.

Sorry, but to get a third external monitor from this docking station REQUIRES that you use the VGA output.

The connectors below the DVI connectors are DisplayPort.

The link given above gives a very good description of what is possible.

Yep. This is what I found on Dell's website regarding the E-Port Plus Port Replicator:

The E-Port Plus Port Replicator with USB 3.0 from Dell™ offers dual digital monitor capabilities along with legacy ports. This docking station includes a latest USB 3.0 technology enabled by Intel in Ivy Bridge. It has replaced the 2 USB 2.0 connectors with the USB 3.0. Plus, the Display Port 1.2 adds the ability to daisy chain displays (4 displays via 1 connector). Also it offers an adaptor complexity reduction. It has non-compromise station designed for enhanced usability at desk. The E-Port Plus Port Replicator has 240-Watt Power Adapter Cord. This product has been tested and validated on Dell systems. It is supported by Dell Technical Support when used with a Dell system.

Note: 'USB 3.0 functionality only works with systems that support USB 3.0 through-the-dock, otherwise that port will act as USB 2.0'


My guess is that the daisychain support to which they refer also applies to the VGA port.

Sorry CompProbSolv. I posted my last comment before I'd had a chance to read yours. I will take a look.

You could also check whether your laptop has an HDMI port. Many do. If there is such a port just connect the TV directly to the laptop's HDMI port.

Since you are already using the top row of ports, It does not looks like you will be able to use the Display port as it is indicated as Video 1 and Video 2.  

So you can use either the DVI port or the Display port for each of the output, not both.

Here are 2 more questions:
1) What kind of connectors do you have at TV side? Or TV do you have? Can you make similar photos with the connectors from TV side?
2) When you send video from laptop/docking station to TV, do you plan to have simultaneously (in the same time) the same video on TV? Mirroring or Extended? Or do you use TV one time as external screen and the other monitors another time?

Ultimately, CompProbSolv's recommendation to use a USB-to-HDMI video adapter provided the ideal solution. Prior to submitting this question, I had no idea there was such a thing.

Austin Texas was right. Using the traditional video ports on the docking station would require using the VGA port. I did not think this would be a viable solution, because I wanted to connect my television to something that supported 1080p. Apparently, VGA can!? If this is true, it's a surprise to me. My laptop has always refused to play HD content over anything connected to the VGA port.

CompProbSolv identified the port I was inquiring about as a DisplayPort. That simplified my search for the appropriate cable or adapter. I obtained a DisplayPort-to-HDMI adapter, but Antzs was correct. When I connected my television to the DisplayPort receptacle, my system could no longer "see" the monitor connected to the DVI port above it.

In response to rindi, my laptop does have an HDMI port, but I want to be able to connect to the television while the laptop is in the docking station. Removing the laptop from the docking station would disconnect it from the other two monitors – thereby defeating the purpose.

The current solution includes a 25-foot HDMI cable (which I already had) and an Insignia SuperSpeed USB(3.0)-to-HDMI video adapter which I purchased from Best Buy for $60. An insignia DisplayPort-to-HDMI solution which I elected not to use (see above), cost $25 at Best Buy.
