We need to give this thread a bit of energy so with my SMART III - and theatertek 2.0.4 via VGA and DMI I have calibrated my system and found some interesting stuff out.
Here is an updated cut and past from the AVforums in the UK that I did whilst bringing it up to date. 28th Nov.
I would rate on a scale of 1-10 each source as follows.
Budget DVD player interlace: 3
Some vertical Banding, Staircase jaggies, A little screen door.
Progscan DVD player:8
Tiny amount of VB
, Some minor jaggies. No screen Door.
HTPC: VGA 10
, No Jaggies. No screen door. Superb contrast.
HTPC: HDMI 10
, No Jaggies. No screen door. Good contrast, lower than on VGA.
I have found the IRIS function basically cuts down on light hitting the screen which lowers black level. I initally set it at the minium aperture of -63, but found it does nothing between -53 and -63. So I've now opted for -53 as this ist the point light level starts to increase.
I have extensively tested the lamp modes and for me there is only the cinema lamp mode that is any use.
Full Lamp: Too noisy but brighter (and so is the black)
A1: Too noisy
A2: Less noisy but adds a little to the peak white, probably in the region of 50+ contrast ratio. Maybe a little slow to update.
Cinema Lamp: The best black level if you can lower the light and quietist.
Preferred settings pre-calibration
Low1 Colour temp
Cinema Lamp mode
Iris - 53
Basic Avia Calibration for B & White level
All picture gizmos like contrast enhancement off.
VGA mode in from TT 2.0.4
As a basis for calibration I used LOW1 (which is analogous in colour temperature to creative cinema but I don't want the other settings that come with creative cinema.)
First time around with SMART I got results of 717:1. Post SMART I got 780:1, colour tracking looked good. Gamma needed to lowered from default of 0 to - 2.
HDMI calibration: HDMI setting L2 (L1 clips level)
Now I've done the same thing with HDMI. Strangely although the picture is smoother with less VB
, the contrast ratio is lowered to 496:1 and 600:1 depending on where you clip red.
So that's where I'm at.
The one thing that confuses me - is that there exists RGB as part of the white balance and then RGB gain, RGB offset and RGB gamma as part of the advanced menu. I'm wondering what value the standard RGB offers as part if the adjustments.
