replace DP option board with HDMI option board

[franbasi]

I want to install an HDMI port on my Elite Desk 805 G6 SFF but, all the HDMI option boards for sale on line are NOT compatible with my Elite Desk 805 G6 SFF.  When I unboxed the PC I was surprised to find 3 DP ports and NO HDMI ports. There are 2 fixed DP ports and a removable "DP option board".  I should be able to exchange this current 

DP option board with a HDMI option board. But all the HDMI option boards for sale have a compatibility list. And my

Elite Desk 805 G6 SFF is not on any of these lists. I have been using a DP to HDMI adapter but, it works badly. flickering, stuttering, etc. The adapter is not a good alternative for a fixed HDMI port!

Please tell me where I can get a compatible HDMI option board for my Elite Desk 805 G6 SFF.

According to the spec on page 54 you need part number 13L55AA

I found one over here

 https://www.ebay.com/itm/265533781373?epid=25045303768&hash=item3dd30bf57d:g:Y-oAAOSw4aRh~Vw9

does it look like it fits?

I was unable to find that part at the 3rd party HP parts store, only eBay.

I would check with the ebay vendor first to be sure

[edit] I had similar problem with a right angle HDMI and a wall feedthrough HDMI but it turned out the cable quality was the problem.  Try a better cable first.

I ordered it on Digitech for 28 francs.
