About the AOC U2790PQU

AOC U2790PQU is listed in the computer monitors category. The recorded specifications include display diagonal: 68.6 cm (27"); display resolution: 3840 x 2160 pixels; panel type: IPS; maximum refresh rate: 60 Hz. This entry covers manufacturer code U2790PQU. Specifications relate to this exact source record; other editions or packages may differ.

The 68.6 cm (27") display is specified at 3840 x 2160 pixels. Consider these together: a larger screen provides more physical space, while resolution determines the number of pixels available. Neither specification establishes brightness, colour accuracy or motion quality.

The listed maximum refresh rate is 60 Hz. To use it, the source device, cable, resolution and input must all support the intended mode. Refresh rate is separate from response time and input lag.

What does the COR Score mean?

One consistent scale makes different publishers’ ratings easier to compare. The original review still tells you why a critic reached that verdict.

Scale conversion · example

8/ 104.00/ 5

An illustration of conversion, not this product’s rating.

  1. Check the match

    Identify the exact model and the version reviewed. Check the manufacturer code, configuration and supplied accessories.

  2. Compare on one scale

    Convert usable ratings to five points, count each publisher once and give each critic equal weight.

  3. Require three critics

    Show the average to two decimal places after three distinct critics. Otherwise display tbd, keeping individual reviews visible.

Find the best fit by considering the score alongside the critic count, review dates, tested version and the strengths that matter to you. Eligible model-level reviews identify the tested configuration. Reviews of different hardware are shown separately and do not enter this product’s COR Score.
