I have just bought the Q9FN and never having had a Samsung TV before its been somewhat a bit of a learning curve.
Anyway I have not had the set professionally calibrated (yet) but have unlocked the Cal-Day and Cal-night picture setting profiles from the service menu. They work fine but neither will switch on HDR settings when presented with HDR material from any source, TV native nor HDMI. All the default settings work just find with the same material on the same source. i.e I can see the HDR logo on the picture icon and if I go into settings can see the values have maxed out from the base SDR settings.
I have done a few soft resets but its still not working properly. The set is on f/w 1153.3. Is this a bug or is the something else I need to set on.
Calibration report using these settings:
TV software/firmware version tested: 1153
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 Q9 review sample's most accurate picture mode, as usual for Samsung, was Movie. It measured quite well, with gamma that came very close to my target and stayed flat. Color temperature was a bit blue at at about 6900K overall, compared to a target of 6500, but that's not bad -- better than my Sony Z9F sample but worse than the Vizio PQ before calibration.
For my SDR calibration of the Q9 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.
Picture settings for SDR:
Picture Mode: Movie
Picture Size settings: 16:9 Standard (Fit to Screen: Auto)
Backlight: 14 [for a dim room, for brighter rooms increase to taste]
Tint (G/R): 0
Digital Clean View: Off
Auto Motion Plus Settings: Custom (Blur Red. 10, Juffer Red. 0, LED Clear Motion Off)
Local Dimming: Standard
Contrast Enhancer: Off
HDR+ Mode: Off
Film Mode: Off [grayed out; when active Auto 1 is usually best]
Color Tone: Warm 2
White Balance: [No adjustments, see above]
Gamma BT.1886: 0
RGB Only mode: Off
Color Space: Auto
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 on the Q9 was Movie once again. It beat any of the other modes, and its default Local Dimming setting (High) was more accurate in terms of grayscale and following the EOTF.
The Q9 was relatively accurate but fell a bit short of some other high-end sets I've tested for HDR. It followed the target EOTF relatively well but didn't track it as precisely as the LG B8 OLED or the Sony Z9F LCD. It showed a plus-blue grayscale in brighter areas (worse than the Vizio PQ, similar to the other two) and color checker measured worse than any of the three. P3 gamut coverage was as good as expected, however, matching the Vizio and LG and beating the Sony (which lacks quantum dots).
