I've ordered a BIOSTAR B350GTN mini-ITX board and planned to pair it with an Athlon 200GE to upgrade my existing A4-5000 based HTPC. I just found a line in the BIOSTAR manual that says the Athlon 200GE will not support HDMI.
Googling the issue, I found some problems with early BIOS versions of several 3xx boards with this CPU and DVI out, but all seem to be resolved since via BIOS updates. However I haven't found any board with an HDMI issue, nor any threads on this except a single 370 story from January where a guy could not get any video out on either DVI or HDMI - but the thread went dead.
Does anyone have any experience with the Athlon 200GE and 3xx BIOSTAR boards? Long story, but I cannot return the motherboard, so I am really hoping that even if there was an issue, it's since been solved via updates.
