I've just gotten a 1080p vizio lcd to go with the mini and it looks fantastic. However, I'm new to the whole LCD thing (we're still SD tube tvs at the house) and was wondering something about the setup.
I'm running HDMI to the LCD. And I'm using a DVCProHD 720p24 sequence with P2 720p24 material. Nope, they didn't add pulldown on import. Part of the reason I got the mini and the LCD, because my DVCam solution won't output 24p to my old SD monitor. Anyway, so I get everything setup 720p24. The mini is outputting 720p, the seq is 720p, the material is 720p, etc. But on the LCD it looks like it's stairstepped. A smaller version of the stairstepping you see on SD video on a HD screen. It's being blown up a bit. But I thought 720p media on a 24" 1080p monitor should look fairly pristine. I suppose the Vizio is doing the upconvert on the fly to 1080p and isn't doing a very good job?
When I switch the output of the mini to 1080p it all looks great. Like I expected. Is this normal? When I watch HD cable on the Vizio some of the channels are 720p and they don't exhibit the same stairstepping as when the mini sends it a 720p signal. Also, I have to switch the mini to RGB if I use 720 or else the Vizio sees it all as green and purple.
Here are a couple closeups of the LCD stairstepping. One image is 1080p output from mini, the other is 720p, and the other is 720pRGB. If you look at the letter M the stairsteppig is pretty glaring.
Good, 1080p yuv
Ugly 720p yuv - stairstepping, green
720p rgb - stairstepping
