Using current technology, there are only two display types that can do any justice to HDR: OLED or zone-array LCDs. And there are currently none that can do it over the full screen area. Very few panels can reach that level however. The industry goal for peak output is 1000nits, or 1000cd/m 2. That means it must produce extremely bright whites and deep blacks. To correctly reproduce any HDR standard, a panel needs a wide native dynamic range. It’s a 27” IPS panel with Ultra HD resolution, extended color that covers both DCI-P3 and Adobe RGB, and most importantly, a 384-zone backlight. Clearly, Dell is aware of this, because today we’re testing the UltraSharp UP2718Q. It also makes do with an sRGB color gamut and QHD resolution. This axiom was proved during our review of Dell’s S2718D.While the screen supports HDR10 signals, it has neither high output nor the low black levels needed to truly display HDR.
