ViewSonic VA2719-SH: a very well calibrated basic monitor

Presentation

The VA2719-SH monitor has a 27-inch IPS panel with a Full HD definition of 1920 x 1080 px. Viewsonic announces a brightness of 300 cd / m², a contrast of 1000: 1, viewing angles of 178 ° / 178 ° and a response time of 5 ms. In terms of connectivity, you have to settle for an HDMI input and a VGA input.

This Viewsonic VA2719-SH monitor is sold for around € 150. It competes with the BenQ GW2470H equipped with a VA Full HD panel and the ViewSonic VG2448 with an IPS Full HD panel, but offering better ergonomics with the presence of height adjustment.

Ergonomics

The Viewsonic VA2719 has a sober and versatile design. The edges of the screen are made of black plastic and the covering of the screen is matt. It is covered with a 3H anti-reflective treatment which perfectly dilutes the reflections of the room.

Aesthetic originality, the circular base is entirely made of glass. Be careful though, it is a real dust magnet and it retains fingerprints very well.

In terms of orientation, the Viewsonic VA2719-SH is content with the minimum, namely the tilt adjustment between -5 ° and + 22 °. The stand is not rotatable and it is impossible to adjust the height of the screen, which is not trivial, especially for office use.

No frills either on the back of the monitor, made entirely of matt black plastic. The connection is oriented downwards, but there is no passage for cables; it will therefore have to be tricky to make them disappear. The screen is compatible with VESA 100 x 100 mm mounts. Finally, the power supply is integrated, which saves space under the desk.

The connection consists of an HDMI input, a VGA input and a headphone output. The screen does not have built-in speakers, but you can recover the sound from the HDMI input via the headphone output.

Four buttons located behind the panel allow you to access the different settings and change the source. The fifth (aligned with the others) is used for switching on / off ... and handling errors are therefore frequent. Navigating the menus and submenus is laborious. The OSD allows adjustment of brightness, contrast, gamma, color temperature, overdrive and offers some presets.

On our 140 x 60 cm desk, the 27-inch screen is fairly discreet. The 25 cm diameter foot remains fairly deep, but its circular shape allows it to be forgotten more easily. The Full HD definition on a diagonal of 27 inches is comfortable when you have a recoil of 70 to 80 cm.

By lowering the brightness to 26 to obtain a white at 150 cd / m², the Viewsonic VA2719-SH consumes 14 W, ie a relative consumption of only 70 W / m², much lower than the average of the monitors tested (100 W / m² ). At the minimum of the brightness (75 cd / m²), the monitor consumes 10 W. At the maximum (345 cd / m²), the consumption goes to 26 W.

Colors and contrast

Good surprise, the monitor delivers a very well calibrated image right out of the box. The temperature curve is perfectly stable over the entire spectrum and the average measured at 6,270 K is close to 6,500 K of the video standard. The curve is also perfectly stable, with an average value measured at 2.2 which locks onto the reference value. Finally, the average Delta E is measured at 2.6, but not many colors exceed a Delta E of 4 and, above all, the blue is not faithful (delta E close to 10).

We lowered the brightness to 26 in order to obtain a white close to 150 cd / m². This does not change the measurements. Finally, the calibration probe also has no effect on these settings. If the temperature rises slightly, the probe cannot correct the colorimetric fault visible on the blue.

The contrast ratio of 1050: 1 is average for an IPS panel. In comparison, the best IPS monitors (PLS), like the Philips 276E7, reach 1,200: 1. In all cases, we are far from the contrasts offered by monitors fitted with a VA panel, such as the Textorm TX32 or the AOC Q3279VWF which exceed a rate of 4,000: 1. In the image, this results in blacks which appear greyish. This is not problematic for office use and more generally in broad daylight; it's only really annoying in the dark and watching movies.

The average difference in backlight homogeneity is only 8% on this 27-inch panel, a very good value for a screen of this size. We did not see any light leaks in the corners or any clouding ("cloud effect") on our test model. IPS technology enables very open viewing angles.

Reactivity

The ViewSonic VA2719-SH does not use Pulse Width Modulation (PWM) to adjust the brightness. It therefore does not flicker and does not cause headaches in the most sensitive people. It also offers a blue light filter allowing software temperatures to be reduced to limit the emission of blue light. It is not compatible with AdaptiveSync, FreeSYnc and G-Sync.

We measured the remanence time at 11.5 ms with the overdrive ("response time" in French in the OSD) set to "advanced". This value limits ghosting (ghost image effect). Beyond that ("Ultra Fast" setting), a rather annoying reverse ghosting effect appears. Finally, we measured the delay in display (input lag) at 9.8 ms (at 60 Hz), a reduced value which does not cause any lag between the action with the mouse and its repercussion on the screen.

Conclusion

The Viewsonic VA2719-SH surprises with its image quality, very good right out of the box, but disappoints with its limited ergonomics. You just have to settle for the only adjustment of the tilt of the panel and two video inputs (HDMI and VGA). In the end, it will follow most people who are looking for an affordable 27-inch Full HD multimedia monitor. For better ergonomics, the ViewSonic VG2448 offers height adjustment, but it is also a little more expensive.
