OSD Setup And Calibrating Samsung's S27B971D
The S27B971D's OSD is identical to the S27B970D. It is almost minimalist in nature, yet still powerful. You get everything you need and nothing you don’t. In fact, the only menu item missing is a wide-gamut option.
Touching the menu icon in the lower-left of the control panel brings up the first screen.
Dynamic Contrast is only enabled in the High Bright picture mode. If you turn it on, you won’t have access to the brightness or contrast sliders. As such, we recommend leaving it off.
Naturally, Brightness modulates the backlight, not the actual black level. This can be set to taste since the overall contrast ratio stays the same no matter what the output level. Contrast clips information at values above 70. Response Time is Samsung’s term for TraceFree. Setting it to Faster reduces motion blur, though in some cases also causes ghosting. HDMI Black Level should be set to Normal for all PC signals, or Low for video signals (such as those coming from a Blu-ray player).
The second sub-menu is called Color and contains a standard set of calibration controls.
To enable the RGB sliders, you need to be in the Standard or Cinema Color Mode. You can choose a preset color temp based on Kelvins, or set the option to Custom and adjust yourself. We’re happy to see the sliders start in the middle of their range. This makes dialing in the white point much easier. And 100-step resolution means a very precise calibration is possible. The gamma presets range from 1.6 to 2.7, and they measure accurately. The correct choice is 2.2.
Next up are the aspect and menu position controls.
For PC signals, there are two aspect ratio choices: Wide and Auto. Wide stretches a lower-than-native resolution signal to fill the screen, while Auto maps the source image in a 1:1 ratio. So, for example, a 1920x1080 signal would be shown windowed in the center of the screen without any scaling.
This menu also contains controls for positioning the OSD. You can place it anywhere, which is particularly convenient for viewing test patterns.
These are the remaining ergonomic features in the Setup & Reset menu:
Turning on Eco Saving reduces the monitor’s power consumption, along with its light output. Menu Transparency is an on/off option. Language offers 14 choices. PC/AV mode is designed to make the S27B971D more compatible with sources other than computers by changing the aspect ratio and color mode options. Ultimately, the best bet is to stay in PC mode and make sure the signal from your video sources (optical disc player, DVR) is in PC mode also. If you are forced to connect a video-mode only device, change the HDMI Black Level option to Low to have the correct dynamic range.
The final screen reports the horizontal and vertical refresh rates, in addition to the input resolution.
Samsung S27B971D Calibration
There are two ways to calibrate this monitor, either through the OSD or with Natural Color Expert, which is provided at no charge by Samsung. For our testing, we used the OSD. But I also ran through the procedure in NCE using an X-Rite i1Pro spectrophotometer.
I settled on Standard mode as the best starting point for my OSD-based calibration. The other modes lock out different controls and limit adjustment (sRGB mode, for instance, locks out everything, including brightness and contrast). And unfortunately, none of them are terribly accurate out of the box. In fact, this monitor takes a slight step backwards from its predecessor in that regard.
The most glaring flaw we found is that the HDMI Black Level is set to Low by default, which, as it turns out, is incorrect for PC-level signals. If you don’t change it to Normal, blacks get crushed and the overall gamma curve ends up quite far off of the 2.2 standard. Once you change this setting, flat grayscale tracking is only a few clicks away. There are no adjustments for the color gamut, but it tracks sRGB fairly well. A more notable omission is an option for Adobe RGB 1998. Any display aimed at professionals, especially at this price point, should include presets for both gamuts.
|Samsung S27B971D Calibration Settings|
|RGB||Red 51 / Green 50 / Blue 54|
|HDMI Black Level||Normal|
If you attempt to calibrate with HDMI Black Level set to Low, you will have all sorts of difficulties setting brightness and contrast correctly. Once you change it to Normal, the sliders work as they should. Contrast clips information above a setting of 70. The Sharpness slider softens the picture when set below 60. Any higher and you'll experience edge enhancement.
