This post concerns taking the end of the TDMS cable and soldering to an HDMI connector to it. Personally if doing something like that I don't do it directly to a standard connector but instead use a breakout board ( as it is much less fiddly) . By breakout board I mean something like this: https://elabbay.myshopify.com/collections/breadboard/products/hdmi-af-bo-v1ac-hdmi-type-a-female-socket-breakout-board-elabguy or like this: https://elabbay.myshopify.com/collections/breadboard/products/elabguy-hdmi-am-bo-v1a-hdmi-type-a-male-socket-breakout-board. If it were me I would use the 'female' type and fix that close to your motherboard and then just attach a regular HDMI cable between the connector and your TV. Oh yes and for a small charge the guy on there will presolder the actual HDMI connector to the breakout board for you so that the only connections you need to make are quite easy.

mac mini mid 2011
Has anyone had any success with this? I'm starting to mod my imac putting inside the logic board of a mac mini 2012 which has a hdmi port and not a dvi. Im ordering a hdmi breakout box to do the connections. As fas as last time I turned on my imac, a few days ago, everything worked as it should. So I know my inverter and monitor work. I dont know if the other guys in this thread had faulty monitors, inverters or maybe the type of solder they used causes issues.

So going back to the question; did any one had this type of mod wroking?

I appreciate any help possible

Yes, I have done TMDS to HDMI breakout board modifications and there is no reason I can see why you should not be successful.
The biggest challenge with these type of mods is usually the wiring and actually fitting everything into the case. Good luck!

This is pretty amazing. Seems to simplify the process quite a bit versus going from TDMS to DVI to HDMI.

I came across a cache of 800mhz /15" G4s and I've been thinking about modding one with a Raspberry Pi. This seems like the ideal solution for the video out.
