ViewSonic VP2780-4K: Image Quality

The ViewSonic’s factory

settings lived up to the impressive figures provided by the calibration

report. Its average Delta E of 0.92 is fantastic – far better than the

2.53 scored by the Samsung S32D850T and even further ahead of the BenQ’s

4.3. That top-notch Delta E is paired with a colour temperature of

6,444K – better than rivals, both of which were cold, and virtually

indistinguishable from the preferred 6,500K figure.

The

ViewSonic’s factory brightness level of 402 nits is far higher than both

competitors, but that’s not necessarily a good thing – it’s a

retina-searing level of backlight and it contributes to a black point of

0.38 nits, which is far poorer than both rivals. That means blacks

aren’t as deep, and it means the ViewSonic’s contrast ratio sits at

1058:1, which is worse than both rivals, though it is still a good score

overall.

The extreme brightness level is just too high

out of the box, but it’s easily rectified. We toned down the brightness

to a more reasonable 133 nits, which saw the black level drop to 0.12

nits – virtually as good as both other screens. The contrast ratio

improved to 1,108:1, and the Delta E improved to 0.79.

That

revised contrast still doesn’t match the figures from the Samsung and

BenQ screens, but it’s still a very good result. The ViewSonic’s far

better colour accuracy makes up for the contrast figures, too, and

provides a keen balance that’s good for work.

We’ve no reason to

doubt the ViewSonic’s gamut coverage levels, either. The VP2780-4K’s

sRGB coverage level of 97.2% is on par with its rivals, and its Adobe

RGB result of 78.7% is reasonable.

The upshot is that this is an

excellent choice of monitor for those

seeking top-notch image quality straight out of the box, with no need

for manual calibration. Just drop the brightness and away you go – ideal

for the enthusiast looking to take that next step or even for pros who

know they won’t be working in AdobeRGB (i.e. image for magazine printing).

ViewSonic VP2780-4K: Screen Modes

Several of the ViewSonic’s screen modes are designed to make work easier but, as ever, quality is mixed.

The

best are the sRGB, EBU and NTSC modes – while these aren’t designed to

produce stonking results in benchmarks, they’re included to allow for

those who work with broadcasting, video editing and other specialised

fields.

The cool and warm colour modes proved inconsistent: both

returned brightness levels far beyond 350 nits, which is just far too

bright – and the cool colour mode’s revised colour temperature of 6,653K

isn’t enough to make a noticeable difference. The warm colour mode’s

temperature of 4,779K is better, but both of these options also made

Delta Es worse.

The text mode’s colour temperature is warm, at

4,766K, and the brightness sits at 374 nits – those figures combine to

produce colours that look oversaturated. The revised Delta E of 2.29

isn’t much cop, either, when compared to the ViewSonic’s previous

performance. It’s even worse in web mode, where the brightness leaps up

to 434 nits and the Delta E declines to 4.89.

More lighthearted

screen modes aren’t much better. The game mode ramps up the brightness

and has poorer Delta E and colour temperature results than the ViewSonic

managed at factory settings, with the movie mode going further in this

direction.

The ViewSonic comes with two power-saving modes that

aim to reduce the screen’s standard power consumption of 38W. The first,

Optimise mode, dropped the brightness to a still-ample 271 nits and

reduced the power consumption to 29W, and the more extreme Conserve mode saw the power consumption fall by a further nine Watts by slashing the brightness level to just 118 nits.

ViewSonic VP2780-4K: Uniformity & Input Lag

Along with its excellent colour accuracy the ViewSonic has very good screen

uniformity. Its poorest performance along the top edge came in the

right-hand corner, where the screen lost 6% of its brightness and the

colour temperature rose to around 6,600K, and along the top of the

screen the Delta E topped out at 2.19 – an isolated score that’s still

impressively low.

The middle of the screen proved similarly

successful: its poorest brightness result was a loss of 6% on the

right-hand side, and the Delta E and colour temperature barely budged. Along the bottom edge the brightness dropped by 8%, again on the right-hand side, but that’s still a good result.

The

ViewSonic’s uniformity is noticeably better than its competitors. The

Samsung’s 32in screen saw its brightness deviate by almost 13% at its

poorest points, and the BenQ lost a little more than that.

Input

lag is also impressive. The ViewSonic’s average of 9.9ms is around three

times better than its two rival screens. This is no dedicated gaming

panel but, if you indulge in some after-hours gameplay, it’s got the chops for fast-paced titles.

Should I Buy the ViewSonic VP2780-4K?

ViewSonic’s latest screen has fantastic colour accuracy and temperature, decent contrast and better uniformity than most

rivals, and it’s got just as much versatility as those competitors,

because of its good ergonomic options and reasonable connectivity.

Many

of its screen modes don’t improve on its standard settings, but that’s

not a problem unique to this screen – and, when the ViewSonic offers

such quality out of the box, only those who need its specialist modes

will likely benefit.

The result is a monitor that is a clear step

up in almost all regards compared to your average IPS 4K screen, with

fantastic image quality and features on offer. Only the very top-level,

professional screens offer more, and even then the main advantage they

have is 100% AdobeRGB coverage, which is entirely unneccessary unless

you work in print publishing.

This performance is duly reflected

in its price, which although certainly high is competitive. If you

don’t need its sharpness and accuracy, its rivals are good office

monitors, but if you work with photography, video or other demanding

applications, the ViewSonic’s extra pixels and accuracy make it worth

the outlay.

Verdict

It’s expensive, but the ViewSonic

justifies its price in several key areas. It’s got quality that trumps

rival screens in almost all departments, a high resolution and plenty of

versatility. Those doing normal office work just don’t need to spend so

much on a professional screen, but it’s worth the cash if you’re doing

colour-sensitive image or video work.
