As any other monitor, curved displays can be calibrated with the Spyder X Elite / Spyder X Pro / Spyder5. Please always plug the Spyder into an USB port in the back of your computer (close to the keyboard/mouse). Please do not use USB-Hubs and/or USB-extension cords as this could result into problems with the power supply.
Check that you have turned off all screen savers and energy savers before starting the calibration. And make sure that the Spyder lays flat on the screen in the center where the color-patches are beeing displayed. Try to prevent direct bright light (e.g. sunlight, desklamp) to hit the screen.
