CNET's HDTV picture settings forum is a resource to help you make your HDTV look its best. Here you will find the picture settings that CNET editors' use to calibrate HDTVs for their reviews. You'll also find settings that our members have posted, so you can give them a try if you own the same TV. This is a unique forum, specifically geared for HDTV picture settings only. So before you jump in to participate, please read this note from CNET senior editor David Katzmaier for all the details involving this forum. Enjoy!
Calibration report using these settings: [see below]
TV software/firmware version tested: 04.10.06
Picture settings notes: CNET is no longer publishing advanced picture settings for any TVs we review. Instead, we'll give more general recommendations to get the best picture without listing the detailed white balance or color management system (CMS) settings we may have used to calibrate the TV. As always, the settings provided are a guidepost, and if you want the most accurate picture you should get a professional calibration.
Prior to calibration my B8 review sample's ISF Dark setting delivered the most accurate image. That's a bit different from the C8 I reviewed earlier, where Technicolor Expert and ISF Dark were very similar. On the B8, Technicolor Expert showed a brighter gamma, more fit for a brighter room, compared to the superb (in terms of hitting the BT.1886 target) dark-room gamma of ISF Dark.
On the B8 there was also a shift toward a blue color temperature in default modes (ISF dark averaged 6625K vs. a 6500K target) that I didn't see on the C8. I don't consider that a significant difference, however, in part because LG supplied the C8 sample (and could have made it more accurate, or at least made sure it was, before it was sent) while CNET bought the B8 sample I reviewed.
For my SDR calibration on the B8 I used the CalMan software's AutoCal feature, which automatically calibrates grayscale, gamma and color to targets of my choosing. Afterward the TV measured almost perfectly.
Another note: Turn Energy Saving off. The default setting, Auto, capped the TV's light output a just 55 nits in my dark lab, which is less than half of my standard dark-room target of 40, and severely limits image contrast and pop.

HDR Notes: Although the CalMan software also provides an AutoCal feature for HDR I didn't use it. I don't yet calibrate for HDR in my reviews; instead I compare the TVs using the best default HDR picture setting. That setting for HDR10 on the B8 was Cinema. It was more color-accurate than Technicolor Expert overall, albeit a tad dimmer (725 nits for Cinema vs. 771 for Tech. Expert). Cinema also tracked the EOTF the best of any mode on the B8, showed a medium-accurate color checker reading and excellent coverage of the P3 gamut. I also appreciated that, just like last year, the LG OLEDs automatically detected and engaged the "HDMI Ultra HD Deep Color" setting designed for HDR sources.
