A Review of the Viewsonic VP2780-4k 27 inch Ultra HD 4k Monitor – VP2780

by on June 25, 2015

The Viewsonic VP2780-4K is a 4K ultra HD monitor that’s definitely been designed with graphics, post production and content development professionals in mind
With a superior color accuracy and performance specs that were put together specifically for optimized content creation, graphic design or print uses, the VP2780 has plenty to offer a professional right out of the box. However, Viewsonic has taken things even further by also having a team of pros manually calibrate each display and give it its own “Color Calibration Factory Report”, thus ensuring a maximal level of even out-of-the-box performance.

At the same time, the manufacturer has also place focus on budget minded professional buyers and though the VP2780-4K is more expensive than a more run-of-the-mill TN 4K monitor for regular content viewing, it comes to market at a price that’s not all that unreasonable for what this display offers.

The Good

The Good is strong in the Viewsonic VP2780-4K and comes in the form of a number of excellent specs.

For starters, the VP2780-4K is one of the first 4K monitors on the market to support the more powerful HDMI 2.0 connectivity standard instead of the more conventional HDMI 1.4. This isn’t a screen that’s been built with 4K gamers in mind, but this feature alone is worth a good deal to this group of consumers now that some of the first video cards for gaming are emerging with HDMI 2.0 connectivity.

For starters, there is the ultra HD 4K IPS display of the monitor, its 4096 x 2160 pixels of resolution offer a lovely crystal clarity that’s unmatched when compared to HD or any lesser form of UHD such as 2K or conventional ultra HD 4K resolution. Furthermore, when you fit those 8.2 million pixels onto a 27 inch screen, the density they take on becomes solid enough to impress even more than what you’d see in a 4K TV.

In the case of the VP2780-4K you’re also getting your hands on an IPS display, which means that off-angle viewing and color rendition will be excellent in general (even if you don’t include this particular monitor’s special color enhancing features).

And speaking of color enhancement, that’s another aspect of the VP2780-4K that Viewsonic invested some extra effort in. The monitor comes with an enhanced color accuracy that leaves many other monitors in the dust on the whole. The technologies behind this include the adoption of 14-bit LUT and 3D LUT to convert image colors from the input signal to the panel and the result creates images that are much truer to life and develop a quality that comes closer to what you’d find with higher end 4K TV screens.

Furthermore, the VP2780-4K comes with 10-bit color, offering 64 times the overall color of more conventional 8-bit screens and a much more professional overall experience for graphic designers and other visual editors who can do more with the 1.07 billion colors this provides.

Finally, a whole plethora of other color and visual display features like 100% sRGB coverage, preset EBU/Gamma correction technology, and Viewsonic’s “SuperClear” IPS panel technology work to complete the picture in making the VP2780-4K one of the finest 4K ultra HD monitors in its price category.

The Bad

Because Viewsonic invested quite a lot into making the VP2780-4K a uniquely high caliber 4K monitor for its price tag of just over $1000 (now lowered to a little over $700), there really aren’t that many defects to report on for it. However, nothing is perfect and this screen is no exception.

For starters, the overall quality of the VP2780-4K is not on the level of true professional UHD monitor standards. This has to be mentioned. While, yes, the monitor offers a much better than average build, some parts of the physical setup are just held on with adhesive and the external power supply is more a feature of lower cost monitors than truly top-shelf models.

Additionally, and though this isn’t crucial, there is the annoying little fact that the VP2780-4K doesn’t come with any internal speakers to speak of, though a 3.5 mm audio socket is waiting to be used for headphones and digital audio can be piped in through two digital video connectors.

Finally, at least some users have reported that the on-screen touch menu isn’t as sensitive as it should be and buttons sometimes have to be pressed so firmly that the monitor has to actually be stabilized with the other hand.

Final Thoughts

All things considered, the Viewsonic VP2780-4K is a fantastic 4K monitor whose less than absolutely top shelf professional design is more than made up for by a truly excellent level of visual display and color rendering capacity, despite the fact that this is an IPS panel instead of an IGZO.

Budget minded visual design professionals would be making an excellent choice with this particular model without getting ripped off on quality.

As we’d already mentioned, the Viewsonic VP2780-4K offers a number of above-average features and even a couple that are distinctly unique among most 4K UHD monitors of any category. Thus:

Most notable on the VP2780-4K are its visual display and connectivity features. In both these areas, this particular monitor absolutely excels at offering quality and very robust specs.

The color accuracy calibration of the screen as well as the 10-bit color rendering combine with the IPS panel technology (which is known for delivering excellent colors) to give users a Delta E ≤2 color accuracy standard, one of the highest there is.

The connectivity specs on the VP2780 are also a major highlight that sets this particular model apart from many cheaper and more expensive models. The monitor features not only DisplayPort 1.2 and mini DisplayPort ports but also comes with two HDMI 2.0 connection ports, one of which is also MHL compatible.

Given that HDMI 2.0 for PC monitors is an extremely new feature that even video card manufacturers are only now adopting to, its inclusion in the VP2780 is a great form of future-proofing and also offers users a whole second means of achieving 4K graphics on the screen at 60Hz instead of 30Hz, in addition to DisplayPort 1.2.

Finally, the Multipicture functionality of the Viewsonic monitor is worth discussing. This feature offers support for multitasking and simultaneous display of as many as four different video sources at a resolution of Full HD 1080p resolution. It also includes both picture-in-picture functionality and picture-by-picture display splitting for increased productivity and graphics work comparison tasks. Furthermore, the screen can be split into two (vertically or horizontally), three or four screens.

Visual Specs

The 27 inch screen of the VP2780-4K offers “SuperClear” IPS display technology for wide angle viewing of on-screen content in excellent color and contrast. However, because we are talking about IPS display, there is the drawback of slightly slower response time. In this case it officially sits at 5 milliseconds. This isn’t bad and won’t be any kind of problem for professional video or graphic editing users of the VP2780 but gamers might be better off going for a cheaper TN 4K monitor that does however offer faster response times.

Furthermore, the 27 inch monitor offers a widescreen aspect ratio of 16:9 and viewing angles of up to 178 degrees horizontal and 178 degrees vertical.

As for the monitor’s resolution, the VP2780 offers a standard ultra HD 4k display resolution of 3840 x 2160 pixels. This is the more commonly found 4K of the majority of UHD TVs and PC monitors and it delivers an excellent pixel density on the VP2780's moderately sized 27-inch screen.

Finally, we move onto color and in this aspect of its overall visual specs, the VP2780-4K truly does seem to excel. The company claims that it offers full 10-bit color for a total of 1.07 billion on-screen colors. However, whether this is being achieved by a genuine use of 10-bit color or simply through 8-bit color that’s been augmented by a process called frame-rate control (which synthesis 10-bits of color) isn’t entire certain. Whichever is the case though, the monitor truly does offer an excellent picture quality with completely smooth color flow and no visible gradients to ruin the on-screen content.

As for the color gamut of the VP2780-4K, in this Viewsonic seems to have been a bit disingenuous on official specs vs. practical reality. While the VP2780-4K is supposed to offer 100% coverage of the sRGB gamut spectrum and roughly 80% of the AdobeRGB spectrum, tests done on an actual model indicate that at least that particular unit only offered 90% of sRGB coverage and 69% of the AdobeRGB gamut.

Furthermore, contrast ratio, while officially rated at 1000:1 is probably closer to 690 – 750:1 in most units sold to consumers.

However, these above deficiencies aside, the overall visual quality of the VP2780-4K’s display truly is excellent and more than competes with what even more expensive, more professional ultra HD monitors might offer.


The connectivity specs of the VP2780-4K from Viewsonic are both straightforward and superb. In fact, this is a category in which this monitor truly excels above almost all others on the market, regardless of price.

The reason why is quite simple: it’s one of the first ever 4K display monitors to offer an HDMI 2.0 connection to users between PC and screen. Thus, in addition to using DisplayPort 1.2 (which the monitor also has) to get their visual ultra HD media at a smooth, jitter-free 60Hz, users can also do the same with an HDMI 2.0 cable. Currently, only a very few PC video cards offer 2.0 connectivity (mainly the Nvidia GTX 980 series) but the fact that this level of connectivity has reached a UHD monitor is a great sign for future developments and the VP2780-4K is ready for that right out of the box.

Additionally, two other MHL ports are available, along with 4 USB 3.0 ports, a DisplayPort 1.2 connection (as mentioned already) and a mini DisplayPort socket as well.

Simply put, the VP2780-4K is probably one of the most connection-ready monitors on sale as of this review’s posting, even if you consider much more expensive UHD monitors.


Pricewise, the Viewsonic VP2780-4K is very affordable for its class even when compared side-by-side to the Samsung U28E590D. Given all the unique connectivity features, the excellent specs on its SuperClear IPS display and its overall build, the current retail price of $717.12 is more than reasonable and represents a great budget option for even professional visual arts designers and video editors.

Not so Great

As we’d already covered, some of the few deficiencies on the VP2780-4K include its slightly flimsy physical design, its lack of internal speakers and its overly insensitive on-screen touch buttons. In addition to these, specific unit tests for sRGB color gamut and Adobe RGB color gamut, as well as tests of actual contrast ratio have been shown to lag behind the formal specs claimed by Viewsonic. However, these spec deficiencies may vary from unit to unit and not be present in some units.

• Excellent connectivity
• Includes HDMI 2.0
• Very solid 10-bit color
• 16:9 aspect ratio perfecto for gaming
• Numerous display augmentation features
