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.
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
Panel Type: S-IPS
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.
Aspect Ratio: Just Scan (NOTE: Just Scan achieves 1:1 pixel mapping. If you need other aspect ratio, feel free to do so, but my H and V Sharpness settings are for 1:1 Pixel Mapping)
Energy Saving: Off
Picture Mode: isf Expert 1 or 2
H Sharpness: 28 (NOTE: Only applicable if you use Just Scan aspect ratio)
V Sharpness: 53 (NOTE: Only applicable if you use Just Scan aspect ratio)
Dynamic Contrast: Off
Noise Reduction: Off
Digital Noise Reduction: Off
Black Level: Low
Real Cinema: Off (60Hz)
Color Gamut: SMPTE
Edge Enhancer: Off
Expert Pattern: Off
Color Filter: Off
Color Temperature: Warm
Gamma: 2.4 (NOTE: LG's default 2.2 is off with other settings. I'm using 2.4 to compensate for those other settings. Final result is a gamma of 2.16)
Method: 2 Points
Red Contrast: 2
Green Contrast: -1
Blue Contrast: 6
Red Brightness: 0
Green Brightness: 0
Blue Brightness: 3
Color Management System
Red Color: -9
Red Tint: 0
Green Color: -10
Green Tint: 0
Blue Color: 0
Blue Tint: 0
Yellow Color: -10
Yellow Tint: 0
Cyan Color: 0
Cyan Tint: 2
Magenta Color: 0
Magenta Tint: -1
djams;20426777 I've attached my .chc file for your reference. This is actually my night calibration - brain misfired when naming the file...[/QUOTE said:djams, is this the same file that you posted sometime ago in our "home" group? I can't seem to be able to open this one (probably operator error). I've been using your daytime one with a few tweaks. My daytime room lighting is probably not as bright as yours so it looks fine day or night, especially with the ambient back light.

Hey Otto - this is the calibration software file. To open it you need to install the (free) Colorimeter HCFR software. This software creates the charts and graphs I've posted in the "home thread".
Edit - I've suspected that a bias light would reduce eye strain in a darker environment, unfortunately this doesn't work in my entertainment center.

Interesting. It appears that LG has changed their product coding for the S-IPS panels because I noticed that there isn't a "W" in your product code. I'm assuming you verified the panel type with a magnifying lens. I'm surprised that your Contrast is so low but it appears that you calibrated with a different set of protocols that I used so that probably accounts for the differences. It's amazing how little the CMS changes right out of the box. It just shows how good these sets are. Good job.

Otto, this is indeed an IPS panel. On the back of the TV, you can see through the cracks and see LC-420WUE labeled on the panel.
Apparently, LG has changed their product coding for the LK series.

That's great! I'm old school though so I'd still check out the pixel pattern. With all of the returns last year for the non-S-IPS panels that LG had, it's always best to be 100% sure. It's cheap and easy.
As far as calibrations go, I've found that you can get a really nice picture if you just do the basics and the CMS. However, if you can calibrate the IRE's
(100 - 0) it just gives the CMS a more balanced look. And on my 520, I've also found that using the HDMI input calibration translates well to the OTA-Cable input. That's important for me because I don't have cable or satellite and depend on OTA for my regular viewing (fortunately we get a ton of HD stations where I live). Oh, and let your tv warm up for about 10 minutes or so before calibrating. It sounds odd but a lot of us noticed that there seems to be a warm up period before you get optimal performance.
Happy calibrating and keep us informed on your progress

This thread got a lot better fast with all this new info
I haven't seen any "W" panels of the xxLK450 and it's been either "D" or "Y". Sadly, every 32 inch I've seen locally have the "D" product code, and so did my Amazon attempt. Plenty of "Y" panels for the 37 inch but that's too big for my desk
My input lag test for the 32LK450 "D" panel was 17-33 ms. My testing method isn't the most accurate (cheap digital camera shots of the TV in clone mode with a Samsung PX2370), but it was good enough for me.

Wow, your profile looked great. I didn't know you can adjust each IRE level individually. I'll definitely give that a shot tonight.
By the way, is your i1 Display 2 consistent? My spyder2 is showing its age and I can't get it to produce a consistent reading every single time. Perhaps that could explain why my curves aren't as close as yours.
Also, could you briefly describe your calibration process? I'm really new at this and could use some pointers as to the tools and strategies for this.
