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!

CNET is no longer publishing detailed while balance or color management system (CMS) settings. Instead, we'll give more general recommendations to get the best picture with more basic settings. Here they are for the Vizio M65-F0.
Dark room settings: Picture mode: Calibrated Dark* Auto Brightness Control: Off Backlight: 30 Brightness: 50 Contrast: 50 Color: 50 Tint: 0 Sharpness: 0
More Picture menu: Color Temperature: Normal Black Detail: Off Xtreme Black Engine Plus: Low Reduce Judder: 0 Reduce Motion Blur: 10 Clear Action: Off Reduce Signal Noise: Off Reduce Block Noise: Off Game Low Latency: Off Film Mode: On Color Space: Auto Gamma: 2.4
Calibration notes: Before any adjustment the P65's Calibrated and Calibrated Dark modes were both highly accurate, but for my dark room I chose Dark. It was a bit brighter than my target 132 nits (40 fL) so I brought the backlight control down a bit.
For adjustments I chose the 2.4 gamma position instead of the default 2.2 for that mode since it measured closer to my gamma BT.1886 target. Color temperature of my review sample was slightly redder than ideal so I tweaked it slightly, and ended up using the 11-point system to brighten up gamma a bit (if you find it too dark, go ahead and use the 2.2 setting instead of 2.4).
Vizio offers three settings for Xtreme Black Engine Plus (local dimming). Medium measured significantly brighter than the default Low in Calibrated Dark, so for SDR I stuck with Low.
HDR Notes: As with past Vizios, Calibrated and Calibrated Dark both showed a very accurate EOTF. As mentioned in the review light output was not that much brighter than the M series, but still very good for both modes at around 860 nits, with no drop-off over time.
Color measurements were solid, with color checker was error decent and similar to the M series. Color gamut was quite a bit better at 94% of DCI-P3 (compared to the M at 82%), in the same ballpark as 2018 competitors including the TCL 6 series and the Sony X900F, which both hit around 95%.
I didn't measure Dolby Vision, just HDR10.
Unlike Samsung or LG sets, you'll have to set the TV's highest-bandwidth HDMI mode -- called Full UHD Color by Vizio -- manually. It's not required for every 4K HDR source, but will be for many.
Why is it when I try using calibrated dark I feel like there are no true colors to my picture.. I am currently using standard which has made it look better but I am in a very dark room.. please help me get my best picture for my quamtom dot.
