for instance the spyder 4pro:
=====================
- Automated Color & Brightness Calibration
-Spyder4PRO’s simple, clear and automated process makes it straightforward to calibrate your displays to a reference condition. You can view and edit images with confidence on a display calibrated to show true-to-life colors and luminance adjusted for precise shadow/highlight detail. - Full-spectrum color sensor -Spyder4PRO’s patented 7-color sensor improves upon colorimeters that use 3-channel RGB sensors. Each Spyder4PRO unit is individually tuned in the factory to accurately handle a variety of wide-gamut and normal gamut displays with ease.
- Single sensor calibrates all your displays –
Spyder4PRO works with your laptop, multiple monitors, iPad and even iPhone. It works with LCD, LED, OLED, CRT, Retina Display, and other display technologies. You can calibrate multiple displays connected to your computer. - Improved accuracy and stability -
The fourth-generation Spyder4PRO has double-shielded color filters for an even closer match to CIE color standards and improved long term stability. Average accuracy increased by 26% and consistency between Spyder units has improved 19%. - Fast Re-calibration Assistant -The “ReCAL” feature makes it quick and easy to recalibrate your display to compensate for changes that occur over time.
- Adapts display to surrounding light -The lighting around you will affect image contrast and appearance. An additional sensor on the Spyder4Pro detects changes to surrounding light and adapts the display luminance accordingly.
although it's for use mostly through a computer,
since most tv's/monitors have inputs from computers
you can use them with those also..
