UPDATE: The below calibration settings are no longer valid because it was calibrated with my inaccurate old Spyder2. I've since purchased a new X-Rite Eye-One Display LT, which has shown much more accurate result so far. Stay tuned and I'll have a the new calibrated settings posted soon.
I've recalibrated another TV, LG 32LD450, using the 75% saturation method and got great results.
See here for djams' suggestion
And here to see my result.
Purchased a 42LK450 a few days ago from Best Buy. It was the CUSY (S-IPS) model.
I just spent the last 4 hours calibrating this TV for near-perfect HDTV - REC 709 standard. I used a Spyder2 and Colorimetre HCFR software.
For those you who want to learn to do this yourself, this is the guide I used.http://www.curtpalme.com/forum/viewtopic.php?t=10457
I've attached my Colorimetre HCFR file for your reference.Near-Perfect LG 42LK450 calibration settings and profile.chc.zip
My goal was to achieve the following
Accurate luminance curve
Accurate Color Gamut
Color Temp: 6500K
White Level: 125 cd/m2
1:1 Pixel Mapping
Here's how close I got after calibrating
Very good luminance curve
Very good color gamut
Color Temp: 6500 +/- 150 from IRE 20 and up
White Level: 125.61 cd/m2
1:1 Pixel Mapping with Just Scan
Of course, none of this means anything unless I share with you the settings I used to achieve this. Before I do so, let me just tell you, movies look amazing after calibration.
Product Code: 42LK450-UB.CUSY-LH

=======Input Label: Use anything other than PC
- NOTE: Using PC as the input label locks out the Color Management System menu under expert controls, which we need to correct the color gamut.
- NOTE2: You can definitely still connect a PC via HDMI to this TV. Just don't use the "PC" input label if you care for these settings.
