AOC I2757Fh And ViewSonic VX2770Smh: Two 27" IPS Monitors

Measurement And Calibration Methodology

To measure and calibrate the monitors, we used an i1Pro spectrophotometer and the latest version of SpectraCal CalMAN software (v5.0.3).

For patterns, we employ an AccuPel DVG-5000 video signal generator. This approach removes video cards and drivers from the signal chain, allowing the display to receive true reference patterns. Connections were made via HDMI.

The AccuPel DVG-5000 is capable of generating all types of video signals at any resolution and refresh rate up to 1920x1080 at 60 Hz. It can also display motion patterns to evaluate a monitor's video processing capabilities, with 3D patterns available in every format. This allows us to measure color and grayscale performance, crosstalk, and ghosting in 3D content via the 3D glasses.

Now, let's see how a £220 IPS panel stacks up to pricier screens.
