I can confirm that my Windows 7 based HTPC with a ATI 4890 video card displays the same issue when the UMC-1 is set to 1080P. The text looks exactly like what you are showing. I run it in pass through mode and it looks fine. |

fyi, i've not seen this, either in auto or pass thru. my umc hdmi output connects to a hdmi splitter, which drives a viewsonic 1080p monitor, and my sony vpl-vw40 projector...

I have a similar problem (v5 UMC code), and started a thread on this topic (http://emotivalounge.proboards.com/index.cgi?board=preamps&action=display&thread=10084). Sadly, the thread was shut down as some folks on it got a little heated/off topic. I was intrigued to see the offset raster (shown above), and for the previous thread, did a bunch of experimentation (including adding a EDID "preserver" inserted between the Mac Mini and the UMC-1). This experimentation is depicted in some photos taken (http://www.flickr.com/photos/tkrodgers/sets/72157623495803245/).
Marcus, I'd love to know if your experience is with the new V6 code or not. V6 was advertised to address "• Video Enhancements for DVI support." ... just curious.

I had the same jaggies while watching blu-ray when set to either auto or 1080i/p, but if I did pass through or even 720p it was perfect. I haven't tried with v6 yet gonna do that tonight. I'm not sure what happened to that thread, but it was the one where I posted pics of the "Marvel" splash screen from "The Incredible Hulk" Blu Ray. Both Lonnie and Big Dan L had commented about it, but we never came up with a solution, other than switching to pass through when watching BDs. *Edit, it may not be relevant in regards to the issues with the Macs, but here is the thread I was talking about. emotivalounge.proboards.com/index.cgi?action=display&board=preamps&thread=9542&page=1 |

If you'd like to avoid the pass-through mode:
Try turning down the "Sharpness" setting. I'd turn it all the way down. I believe the "0" default (in Auto and 1080p) is applying some sharpness processing.
Most video sharpness processing does exactly what you're seeing. It especially messes up anti-aliasing on text.

Yes, I can confirm that setting sharpness to 0 removes the artifacts. So why did they choose to set it to 50 by default? |

btw, i should have been more clear. in both v5 & v6 version of the firmware, i have not seen the first picture - bad colors and/or shifted images. i _have_ seen jaggy text when UMC video is not in pass thru mode - which isn't too surprising due to known problems with anti-aliased text & video enhancement algorithms (as loopinfool mentions).

The UMC-1 is a TV that can be bought in retail stores?

I thinks it's more like the code monkeys decided to put everything in the "middle" on reset.

The UMC-1 is a TV that can be bought in retail stores? No, but some people think "punchy" video looks "better". So, chip makers and video gear manufacturers often set their defaults so things look that way. Then, when some guy buys brand X, he tells his friends that movies look "better than ever" so his friend buys brand X, too. It's not accurate, and I don't think it looks good, but it sells product to the average consumer. Emotiva is a good company and provides enough controls to make it "right". There's still pressure to make the defaults what they are. The really bad thing about the UMC-1 defaults is that most displays also default to some processing (especially sharpening), so there's double-processing going on. That can look really bad. - LoopinFool |

So did adjusting the sharpness and reducing "torch mode" help with the mini Mac in regards to the anti-aliasing?
I never really messed around with the settings, because pass through looks so good.
