    I have a Vizio 1080p 37" TV which I had a dell hooked up with a cheap nvidia card (forget the chipset but it was 128mb ddr2 ram).

    VGA cable to the TV and it was fine at 1920x1080. Well the computer died and I went out and bought a brand new mac mini.

    Got it with the Mini DisplayPort VGA adapter (The $30 Apple one from the apple store).

    Video is wavy - kinda shakey. It's not consistent though and it comes and goes (but out of 10 minutes, 9 minutes of it will be this way). It's also pretty minor and I can barely notice it 6 feet away. But looking at it at the desk I notice it.

    It does it on lower resolutions and it does it on 720p until I changed the refresh to 75hz. Then it stopped. I don't remember setting the old desktop to a certain refresh but the Mini only allows 60hz at 1920x1080

    Think I have an issue? I was going to go return the Mini DisplayPort VGA adapter and get the Mini DVI Port VGA adapter. See if the quality changed. Otherwise I found a Mini DP to HDMI adapter on Monoprice I was going to give a try.

    I just can't imagine the mini will have any trouble feeding 1920x1080 with its new graphics card and perhaps it's an issue with the digital to analog conversion? I know for a fact the TV works fine because other machines work fine.

    If I get the Mini DVI converter I can try my MacBook but that only has the onboard intel (144mb shared) not sure if that does that high of a resolution

    Whatcha guys think?

    I know this might not be a good answer, but I have a 37" 1080p Vizio connected to my 2009 Mini via minidp-hdmi and it is crisp as ever. Why not use hdmi?

    That is a very good answer (and question).

    I just bought it last night (not even 24 hours ago) - Apple doesn't sell a DP->HDMI adapter so I bought what was available so i'll have to order one. I'm going to return the $30 one that doesn't work well though heh

    I suppose I could pickup a DVI->HDMI cable and use the DVI adapter the mini came with.

    Well I went to the apple store and exchanged the vga adapter for a dvi->hdmi cable.

    Weird stuff here is that it has a butt load of lower resolutions. Then it has TV resolutions 720p, 1080i, 1080p. All require Overscan to be enable and without overscan enabled the image is centered and has a few inches of black on all sides. The quality isn't as good as far as fonts go - they seem less smoothed and more jagged (The vga looked great, just had that shake).

    I dunno. I have a dvi->vga converter at my work so i'll try that on the minidvi port adapter and see what I get. But this is usable if I don't get any success with the VGA port. Just kinda annoying that my old crappy dell had none of these issues :(

    Well I turned on some smoothing in the menu of the tv and it looks great now. Starting to feel a lil bit better now.

    Just gave this thing a fresh OS X Install and it's running good so we'll see - just need to setup my itunes and i'll be happy heh
