: lg ps30 setting question
2010-02-08, 12:11 PM
I just purchased a lg ps30 1080p plasma tv at costco and I was wondering if anyone had good settings for it.
I've been playing with it for two days and just don't think I have it right.
Each TV is unique, so someone else' settings are not applicable to your TV. See the following post on the proper optimization of your TV: If you have specific questions about what a particular setting does, please feel free to post here and we'll try to answer as best we can.

That's true, and I have one of the calibration discs on the way, but I have seen people post contrast 65, color 55, etc. I thought that might be helpful.
Well, it's not really helpful if you read through the FAQ on using other people's settings:
I've optimized plenty of TVs and the identical make/model TV may have a setting of 40 in one home and 60 in another - mainly due to manufacturing tolerances, but also due to application and device connection. If the same setting is on two different TVs, it's usually just by "luck" and would certainly not apply to all the various settings.
Most times when you do find settings posted on the web, they are incorrect - for example people optimize in the wrong picture mode, or don't turn off certain harmful settings, or use the incorrect colour temperature, etc.

57 is completely correct here. Not only do parts tolerances and the equipment you connect play a role, but your viewing environment is significant to your settings. The first step you could take is getting a basic video calibration set up disc. Others have a professional come spend a few hours on the display and calibrate it correctly with measurement tools.

Every client of mine who had settings off the web - they ended up being useless. Not even close and far outside of JND (just noticeable differences).

Get a professional you wont rergret it. Mike Osadciw (The Highest Fidelity) just did mine and the difference is night and day. I sat through the entire calibration and am much more educated on why the picture looks the way it does.

While this is off topic, I do have some comments regarding this statement.
Not only do parts tolerances and the equipment you connect play a role,
Electronics manufacturing has progressed to the point where these tolerance have been reduced to a fraction of where they used to be. For Digital TV in particular, the major brand's deviations are usually mimimal. They then calibrate the TV's off the assembly line to meet whatever color and grayscale spectrum for their particular product line. If you took 10 TVs of a particular brand and model, put them in a room with the same lighting and source content, you would be at a loss to find differences between the sets visually but more importantly, meter measured differences would be mininal.
but your viewing environment is significant to your settings.
This is the single most important aspect of why settings are different. This is not a result of the first statement but stands on its own. Using the first statement to justify this one is counter productive.
I totally agree with the statement regarding using a set up disk to adjust settings as they provide material and instructions that allows more subjective settings to meet a technical definition of what "should be". Keep in mind however, that most people like certain visual attributes on a picture that have no bearing on technical specifications.

Hi there m0gr81
Those two (actually 3) comments were meant to be separate.
Image settings can be based on:
1) Parts tolerances (according to many in the industry, these TVs are made with cheap parts that have variances over the manufacturing period of the TV. TVs aren't built to military spec or else they'd cost far more than what they do.) This may result on a correct (eg.) contrast setting of "36" on one TV and "32" on another of the same model. The guy who needs it set at 32 but uses someone else's "36" setting would be pushing his TV whites into clipping, wiping out white detail. This happens and I've seen it happen on the same model.
2) Components in the system - while the TV is calibrated to a reference video generator, the components in the signal path also need tweaking to match and there is a method of doing this correctly. If they can't be, we must readjust at the TV
3) Room lighting/color - will affect how one perceives video information and is too often overlooked especially when designing rooms for front projection applications.
