Dell S2719DM Display Features

Corning Iris Glass Light-Guide Plate

Edge-lit LED displays use a light-guide plate (LGP) to distribute light uniformly throughout the panel, Usually they are made up from pure PMMA resin, but such polymer LGPs can warp and expand with changes in heat and humidity. They therefore require a wider bezel, greater thickness and an air gap to account for movement and expansion.

To keep it thin and reduce the bezel size, the Dell S2719DM (Malaysia | US | UK) features the Corning Iris Glass Light-Guide Plate technology.

Because it’s made from glass, the Corning Iris Glass Light-Guide Plate is rigid. This removes the need for an air gap, and a thicker backlight, greatly reducing the thickness of the display. Its dimensional stability also ensures reliable transmission of light from the LED edge lighting.


Extra-Bright QHD Panel

The Dell S2719DM (Malaysia | US | UK) has a QHD panel with a resolution of 2560 x 1440 – a popular resolution for both gaming and work. That is nothing special, of course. What lifts it above the crowd though is its brighter panel.

Dell S2719DM BrightnessMany monitors of its class have a typical brightness of 250 to 350 nits. The Dell S2719DM (Price Check) boasts a typical brightness of 400 nits, with a peak brightness of 600 nits.

The increased brightness is not only about a brighter panel. Higher brightness is a critical aspect of the monitor’s HDR performance.


DisplayHDR 400

Many HDR-ready monitors support the open HDR10 format, but this does not mean that they are necessarily “true” HDR monitors. This is where the VESA DisplayHDR program comes in. It is a set of standards that HDR monitors should comply with, so that consumers can be guaranteed of certain levels of HDR performance.

DisplayHDR 400 logo

The Dell S2719DM (Malaysia | US | UK) is a VESA DisplayHDR 400-certified monitor, which means it has to meet or exceed these requirements :

  • Deliver true 8-bit image quality – on par with top 15% of PC displays today
  • Support global dimming for better dynamic contrast ratio
  • Have a peak luminance of 400 cd/m2 or better – up to 50% higher than typical SDR
  • Minimum requirements for color gamut and contrast exceed SDR (95% of sRGB)

The Dell S2719DM (Malaysia | US | UK) exceeds those requirements with a peak luminance of 600 cd/m2, and a colour gamut of over 99% sRGB. However, it does not support local dimming, and is thus considered to be an entry-level HDR monitor.

sRGB Colour Gamut

The Dell S2719DM (Malaysia | US | UK) supports a colour gamut of over over 99% sRGB, and 85% DCI-P3. What’s the difference between the sRGB and DCI-P3 colour spaces? Take a look.

DCI-P3 vs sRGB

Don’t get confused by the two numbers. What they basically mean is that the Dell S2719DM (Malaysia | US | UK) is essentially an sRGB monitor. It may offer an almost 100% sRGB coverage, which is better than many sRGB monitors, but you will need to look elsewhere if you need your monitor to support a wider colour gamut like Adobe RGB.


AMD FreeSync

Dell does not mention this, but the Dell S2719DM (Malaysia | US | UK) monitor supports AMD FreeSync. When used with AMD graphics cards and APUs, the monitor will dynamically adjust the refresh rate to prevent tearing and stuttering.

AMD FreeSync comparison

While the Dell S2719DM (Malaysia | US | UK) has a vertical scan range of 48 Hz to 75 Hz, it is limited to 60 Hz at its native 2560 x 1440 resolution. As long as the frame rate of your games are 48 fps or higher, FreeSync will ensure that they are tear-free.
