Dell Optiplex 7070 micro - Adding optional HDMI port - Part number ?
Hey guys
I'm looking to add a HDMI port to a 7070 Micro
Currently I have 2 x DP and I am looking to run a 3rd screen
In the manual it lists - . DisplayPort/HDMI 2.0b/VGA/USB Type-C Alt-Mode (optional)
There is a knock out blank for the port at the back of the chassis , Can anyone advise on part numbers please ?
Tech support only offer Graphics cards for the SFF models which dont fit
Any advice much appreciated
1 person also has this problem

thanks for trying , I am holding off purchase on a 7070 micro as I need a triple monitor set up
I have to be able to buy an accessory part so I can install it
Its a pity dell don't list the part numbers in the user manual for the optional parts ...

Thanks for the suggestions guys , very helpful
Its interesting that the display port looks to be the correct part but people have been complaining it doesnt fit the motherboard in the reviews?

I wonder if anyone else in the community have successfully installed this DP adaptor or the HDMI?
I have had 2 sessions with Tech support and both have tried to sell me Graphics cards meant for the SFF or tower which dont fit the micro
Reply I called my account manager and they could not find a part number.
I am positive this is a daughter board with cable and screws.
@DELL-Chris M may have better information.

Call Dell Spare Parts (USA 1-800-357-3355, Canada 1-866-440-3355) and ask for price and availability of the Dell 5 digit part number.
