I don't understand what you mean by "Smart Display".
Sorry, certainly not an industry-wide, accepted term but one that's been around since at least the Sony Artisan days.
Display electronics
and software that allows one to produce multiple calibration targets (and yes, you do need to use an instrument ideally to get them), whereby you can load all this into the panel on the fly and swap the appropriate ICC profile, done high bit (Hardware calibration LUT).
One could produce settings A and settings B for say i1Profiler. One could toggle between the two by conducting either (in this case 12 minutes) process to calibrate and produce a profile for each. With the "Smart Display" this is done on the fly, in seconds.
Best described in the SpectraView manual and the part about Multiple Calibration sets is part of the '
smarts":
The SpectraView system uses a color sensor to take color measurements of the display screen during calibration. The software analyzes these measurements and sends color adjustment commands directly to the display monitor. This means that color adjustments are made in the monitor rather than in the video graphics adapter, resulting in full use of the number of colors available on the graphics adapter and a much brighter image with the maximum possible color gamut. With SpectraView, the video graphics adapter is not used at all to make any gamma or Tone Response Curve corrections to the display, so the full color resolution and fidelity of the system is maintained.
Main Features and benefits
SpectraView provides the following features and benefits:
• Automatic calibration - SpectraView communicates with the display monitors using Display Data Channel - Command Interface (DDC/CI) which is a two-way communications link between the video
graphics adapter and display monitor using the normal video signal cable. No extra cables are necessary. All adjustments to the monitor settings are done automatically using this communications link. A USB connection between the host PC and display can also be used on MultiSync PA Series models only. It is not necessary to manually configure the monitor as all of the necessary settings are made by the software.
• High bit depth internal Look Up Tables (LUTs) - each LCD display monitor supported by SpectraView II features three internal 10, 12 or 14 bit LUTs (depending on the model). These tables allow very precise adjustments to be made to the display’s Tone Response Curve without reducing the number of displayable colors or introducing color banding artifacts.
• Multiple Calibration Sets - Different display monitor calibrations can be instantly loaded allowing quick and easy switching between different calibration settings without the need to re-calibrate the display. Each time a calibration set is loaded, the necessary monitor settings and ICC/ColorSync profiles are automatically updated.
With respect to your question about targets:
About Targets
SpectraView can also create custom Targets, which can then be exchanged with other SpectraView display users, providing identical calibrated displays.
A Target consists of up to five specifications that describe the color characteristics of the display:
• Gamma or Tone Response Curve (TRC) • White Point
• Intensity
• Contrast Ratio
• Color Gamut
The target can be one you create and share or a preset target supplied in the software. Click on one, boom, it is loaded and used and the associated profile is then 'found' and loaded into the system for ICC aware applications. And yes, calibration with an instrument must be conducted to do this.
And yes, many displays claim DDC but it's often very wonky (non technical term for, it often doesn't work well or at all). It does work fully with this kind of display system.
