I'm anxious to try out this disk but I have to wait for the right conditions. I don't have blackout blinds in my living room where the HT is so it can go from annoyingly bright during the day to dark at night. I need to wait for a happy medium -- maybe a cloudy day -- in order to calibrate.
Aside from the video calibration have any of you gone through the audio calibration using a sound meter? Did it make a major difference? I'm pretty happy with my surround as is so I'm not sure if it's worth it to buy a sound meter.
Here are my variances on contrast (I don't own the WOW disc, merely going on what other LH90 users are reporting in the thread for my TV).
1. Built-in TV contrast pattern = 87
On medium gamma, gamma setting effects the pattern's optimal setting where the two white blocks match in intensity. MOST HD cable TV content looks quite natural on this setting and seems to be the setting my brain 'accepts' as the best compromise between TV programming with differences in contrast from the source material.
2. DVE = 97
This is probably the only pattern I would have trusted with the reverse top/bottom left to right contrast scale and I get the '97' setting on medium gamma. The 2nd to last white block is adjust to 'just' match the "whiter than white" block. The result gives me a picture quality with some nice 'pop' but sometimes I get the impression the contrast is too high or something is 'wrong' on some commercials.
However, when I set the backlight at this contrast setting when comparing a movie or show shot 'outdoors' when looking out of my window and then matching up the intensity of 'real outdoors' with my TV's reproduction of a similar daytime intensity, well, the '97' contrast appears to be the most 'real' setting ironically, even though some HD cable TV content just looks like the high intensity whites are just a bit smooshed together/clipped.
That's Ironic since the DVE contrast pattern CLEARLY shows what should be the top white output on their test pattern and I'm able to see each level of difference on the larger main blocks in the high intensity white spectrum of the test pattern.
However, when looking at the more detailed gradient line, it's very difficult to see the contrasting transition between whites in the brightest output portion of the test pattern.
So, these results have me questioning whether the test pattern's larger blocks are truly a good indicator for the proper upper dynamic range of a display and has me questioning whether it's taking into account the TV's true capability to display differences between those whites. It maybe forcing users to set their contrast too high. It's undeniable however how incredibly close to 'real life' this contrast pattern has brought my TV on the right content (good quality outdoor HD films/TV programs).
Perhaps the pattern is perfect but my TV is just 'barely' able to show a minor difference at the top output of the pattern but overall, my TV may not have as detailed an output at the top of the spectrum to give realistic detail gradient differences?
I have put pictures in the thread for my TV on page 88 of the thread (on my computer it's page 88, but may or may not be the page on yours) which I think shows a very close representation of how my TV looks on the DVE settings. The results have undeniable 'pop' but even in the pictures it seems to give the impression the contrast is set a bit higher than the TV's capability to present the differences on the brightest white outputs. Although very correct looking on daylight scenes in light 'intensity', it's just a tad short of what I would consider a 'perfect' representation of the upper white spectrum of whites. I'm STILL impressed this TV could even come close to producing what I see in 'real life' as no other TV I've ever owned could pull this off (competing with and showing off a VERY realistic daytime picture).
3. The Monster calibration disc = 94
Right inbetween the TV's built-in pattern and DVE's pattern. The result still seems to clip some of the brightest whites together although not as bad as the DVE pattern on clipped whites but it's also not matching 'true life' outdoor realism like the DVE disc's settings.
4. WOW disc. I myself don't own this, but from the settings other people have reported, it's very likely the WOW disc's contrast pattern would indicate a "low 80's" setting. I don't want to shell out $30 to $40 just to confirm this as I'm confident those reports from other user's with my LH90 model are doing things similarly to what I would do as their results from DVE & the TV patterns are similar to my settings.
So, I would like to communicate again to those people who prepare and setup these calibration patterns to please get together and try to offer some consistency on what is 'correct'.
