Unfortunately , I met the same problem with HDMI port on my 9560 after upgrading the latest TB firmware "Intel_TBT3_FW_UPDATE_NVM26_0CT6J_A03_4.26.04.001.exe". Now I have to wait a reply from DELL as I cannot use my external monitor.

Hey team, I'm having this issue also. XPS 15 9550 - same firmware update as you've all applied, resulting in the onboard HDMI port inverting colours.

Appreciate a solution, Dell.

Happy to PM my service tag to a dell rep.

@Timblaktu - I have the same issue. Tried to apply it (have the TB16 dock) and it failed, but no reason was given. Although looking at the replies in this thread,  that's probably a good thing!

I am having the exact same problem.  My Precision 5510 HDMI port immediately became unusable after installing the Thunderbolt firmware update.  A huge problem.

I suppose I am lucky.  My XPS 13 9365, which is using a new firmware NVM 23 seems to be OK.

Thanks @oduis, it wasn't clear to me from the thread that the HDMI port not working for people is the laptop's HDMI out, and that the HDMI out on the TB16 dock (which is all I plan to use) works fine with the new Thunderbolt Firmware 4.26.03.001,A07. (please confirm/deny that _that_ is what you meant.)
