<div>I've got a strange problem which I've been beating my head against all weekend. I received my new Zotac ion (A) board this weekend - the one with the Atom 330 and the external DC power supply. I set it up no problem connected to my computer monitor (over HDMI) - everything worked - audio of HDMI included. I was happy.</div>
<div> </div>
<div>I then moved it from my office to the family room where it will serve duties driving a 42" LCD 1080p (a Dynex DX-LCD42HD-09). I have had a mac mini (using Ubuntu 9.04 and 8.10 before that) driving the TV using a DVI to HDMI cable. Everything was fine with the mac - except I wanted to use HDMI audio, and the mac couldn't play back high def h.264 and VC-1 from blu rays.</div>
<div> </div>
<div>When I connected the ION to the TV - everything went fine through the BIOS posting, and ubuntu splash - but when the picture was meant to come up at the login screen - nothing. Just a black screen.</div>
<div> </div>
<div>I reinstalled Ubuntu 9.04 from scratch. WHen it was using the vesa driver before installing the nvidia drivers- it was fine and could drive the LCD over HDMI. The minute I switched to nvidia - same thing blank screen. (remember this worked driving 1080p with my computer monitor over HDMI). I tried 8.10, I tried different versions of the nvidia driver -- even installing the nvidia .sh from the nvidia website - no dice.</div>
<div> </div>
<div>I extracted the modeline and put that into my xorg.conf. Xorg.0.log showed the modeline being validated, but same thing - blank screen. I reinserted the mac mini, and double checked the modeline the intel card in that was using. Same thing - blank screen. I tried other (lower) resolutions - same thing.</div>
<div> </div>
<div>I tried using the same DVI - HDMI cable I was using with the mac - same thing, blank screen.</div>
<div> </div>
<div>I tried using the VGA connection and the modeline I was using for my DVI connection - and get a wonderful 1920x1080 60p signal!</div>
<div> </div>
<div>So - now I'm very confused.</div>
<div> </div>
<div>The LCD TV appears to work - the mac mini drove it fine using its HDMI input</div>
<div>The board seems fine and working with the nvidia drivers - when using my computer monitor rather than the LCD TV</div>
<div>The modeline seems fine - the VGA input is happy with it</div>
<div> </div>
<div>I've been playing with every combination I can think to throw at xorg.conf and am deeply confused. Do these two products when combined with the nvidia driver just not want to speak to each other?</div>
<div> </div>
<div>Thanks for any ideas!</div>
