Round-ups
By published

With monitor prices creeping lower than ever, even the latest IPS-based models are now affordable. Today, we look at a pair of 27-inch, LED-lit, 1080p displays from AOC and ViewSonic. Both products recently hit the market and are selling for around $300.

Measurement And Calibration Methodology

Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

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 $300 IPS panel stacks up to pricier screens.
