The ASUS TUF Gaming VG27AQL1A displays a good, wide color gamut for HDR content. It has excellent coverage of the commonly-used DCI P3 color space, but its coverage of the wider Rec. 2020 is a bit limited.
Note: The DCI P3 coverage is much lower than the advertised 95% coverage. This is normal and is due to the way we measure DCI P3. We measure DCI P3 by sending a Rec. 2020 signal, but unlike most reviewers, we limit the colors we’re sending to the DCI P3 primaries. This results in a lower, but arguably more accurate measurement.
