I tried the factory reset, and it doesn't reset those values. There is no one 'default' because it varies from set to set.

Also, due I think to the panels driving design they will not produce a full-screen bright white. I comes out grayish.

I just purchased a 55VT30 and with the help of this forum (thank you very much) I have found I need an EEPROM update. I have a tech scheduled to come out tomorrow to install the update. To confirm the tech knows what he is doing, what should I be looking for or what questions should I be asking?

I have a few questions which I feel like are noob and I apologize if they are:

1) Are the reference setting determined above (namely for the gt30) based on ambient room lighting (or a lack of it)?
2) Do the SM Offsets only effect the THX picture mode, or all picture modes?
3) Do all sets have the same starting SM Offsets, i.e., for the gt30 R-DRV is changed 6 times with the Vol - button. But was the initial value?

Many thanks for the research and sharing, D-Nice!

3 The values are all different due to panel and circuit differences. There is no common initial value. All the tv's are loosely calibrated from the factory using the same equipment so then each tv will have different initial values to match that calibration. The offsets are the button presses from what you have now. If you need to go -6 then hit down 6 times.

FYI

I've been playing around with the Spears and Muncil test disc on my 60gt30 and have discovered that in THX mode peak whites are clipped to some extent at anywhere above a contrast setting of 46. This doesn't seem to be the case in several of the other modes i.e. Game, Custom, Vivid. The clipping appears to involve about the top 6-8 steps in peak whites in the "dynamic range high" test pattern. Standard, THX, and Cinema all appear to behave similarly while Game, Custom, and Vivid appear to have a greater dynamic range available. Source is a ps3 via HDMI with all standard video range settings applied.

As you may know, in real world viewing, this loss of peak white info can cause subtle loss in high white details depending on program material.

I'm experimenting with Custom mode at this point with Low panel brightness as it seems to be adjustable to closer to how THX looks overall (at least to my eye).

The other option would be to stay in THX mode but drop the contrast setting to 46 or lower--although to me this is a little subdued.

It's notable that I'm using factory default SM settings (have not altered the SM).

Any calibrations done in custom affect THX.
like WB, color, saturation.

Dave O measured 37 fl with THX and 26fl with Custom and this is consistent with what others have measured. This increased light output may be related to the reason why THX is clipping peak whites but that is only a guess on my part.

User menu settings in Custom do not effect those in other modes AFAIK.

From experience THX works better for dark rooms and Custom For
bright rooms.
Has to do with gammas.
This difference will give better performance when
color, contrast, and brightness are optimized for a true
pic.
As always, your personal tastes will be the judge.
I find that thx allows a better pic at low light setting than Custom and custom a better pic at high light

Apparently, it's all in how it's measured.
The peak white clipping noted above is of some
concern though.
