DWhitley, Thank you very much for joining the Intel® NUC communities.
First of all, let me apologize for any type of inconvenience, but the thing is that when you use any type of adapter to connect the NUC to a monitor or TV, some compatibility problems might be expected, the way Intel tested the NUC was by using a straight connection. There are many different adapters that will work with the NUC but some others will not work as expected, normally we recommend to use an active adapter, on the link below, you will find a list of some adapters that were tested by Intel as compatible:
Additionally, the steps you tried are the ones we recommend to try to make it work, which are to try a BIOS update to the latest version and to install the latest graphics driver from our web site.
On the following link you will find further details about Intel® graphics and a TV connection:
I hope this information will be useful for you.
Any further questions, please let me know.
