Review site Secrets of Home Theater and High Fidelity just posted an excellent review of the GV47LF. The reviewer used Datacolor Colorfacts professional calibrating equipment to calibrate the television. So any owners of the GV47LF should head on over there and check out the entire the review for tips on getting the best picture from the television. I can say their suggesting settings improved my viewing experience.

Their suggested calibrated settings for the Vizio GV47LF:

  • Red: 133
  • Green: 126
  • Blue: 106

Their suggested advanced picture adjust settings for the GV47LF:

  • DNR: Off
  • Black Level Extender: On
  • White Peak Limiter: On
  • CTI: Off
  • Flesh Tone: On
  • Dynamic Backlight: AI
  • Adaptive Luma: On

I’ve been messing around with the backlighting settings on the television, and I’ve come to the conclusion that leaving the dynamic backlight setting on AI is the best way to go, whether you’re in a well-lit room or in a dark room. I’ve found that turning off dynamic backlighting in the advanced settings and adjusting the manual backlight to a low setting (less than 40) tends to make dark scenes murky, and can turn a bright sunny scene into an overcast day. If you use the above settings and dynamic backlight on AI, you’ll get the best compromise of black levels and vivid colors that this TV has to offer. You’ll also have more peace of mind by not having to fiddle with the television anymore, knowing the settings are from a professional calibration.

*Update* I’ve been using these settings for months now, and I am still totally happy with the picture in all lighting settings. I have not touched the settings nor plan on touching them any time in the future. Again, I recommend viewing your Vizio GV47LF in dimly lit rooms–avoid total darkness.

*Update II* Please note that picture settings for each input (broadcast TV, component, HDMI, etc) must be changed while in that mode–they do not replicate across all inputs. See my post on the subject.

*Update III* My GV47LF developerd a buzz sound (out of warranty, of course) that was produced from having the dynamic backlight set to AI. I have now changed it to On (this solves the buzzing problem while maintaining the bright, vivid picture the dynamic backlight provides). I have also messed around with the other picture settings and find that reducing the brightness to 47-50 and having contrast cranked up to 90-100 helps increase the black levels.
