Q1: ViewSonic is not a brand I am familiar with—is the ViewSonic VP2780-4K comparable to the more well-known brands in terms of quality?
A: While ViewSonic is not as well-known as Dell, LG, Sony, Samsung, or Panasonic, the ViewSonic VP2780-4K is actually a very capable and high-quality monitor that is an excellent choice for users seeking midrange Ultra HD (4K) monitors.
This 27 inch monitor is moderately priced at around $890 at full retail price, but can probably be found less expensively during deals and the holidays.
The performance of the ViewSonic is excellent in the following ways: the display has an IPS (in-plane switching) panel with 3840 x 2160 Ultra High Definition (UHD) resolution, the 10-bit color depth, and the W-LED Edge Array backlight. This is true 4K at its best.
Much like the Dell P2715Q model, it has an unassuming exterior when turned off—with a black frame and a plain stand. However, once you turn this monitor on, it is clear that ViewSonic is not an inferior product. The sharpness of the 4K content is incredible, with solid colors, and great gray-scale performance. There are also a lot of ports on this monitor, making daisy-chaining or connecting devices a snap. In fact, there are two DisplayPort inputs (one full size, one mini); one HDMI 2.0 port; two HDMI 1.4 ports—which are also compatible with MHL devices; an incredible three HDMI 3.0 ports; a headphone jack; and two additional USB 3.0 ports are on the right side of the cabinet. It’s safe to say you won’t have any connectivity issues.
Considering the price of this monitor, the Dell P2715Q is cheaper than this model and is more or less similar. However, this ViewSonic offers next-generation connectivity options through ports and inputs/outputs. It also has Dell’s 8 million plus pixels in the display for an incredible display. The ViewSonic model has an impressive 10-bit panel, which means it can display up to 1.07 billion colors. This ViewSonic also has superior color accuracy. While the Dell P2715Q has a delta E less than 3, the ViewSonic VP2780-4K offers delta E equal or less than 2. This offer brilliant color variations that are nearly limitless and colors that are nearly imperceptible from real life according to its delta E consistency.
In the end, the ViewSonic wins the recommendation, even though the Dell is somewhat more affordable and is still a world-class 4k monitor. This ViewSonic model is extremely comparable to the more well-known brands and can in fact, defeat many of them with its specs. For those who want more connectivity and insane color variations due to work or play that involves graphic designing or an appreciation of color, then the ViewSonic would be the better choice.
Q2: What are the streaming and display-sharing capabilities of this model?
A: Unfortunately, while the ViewSonic VP2780-4K has excellent picture quality, it lacks HDCP 2.2 compliance, which makes it rather useless for connecting to electronics with HDCP 2.1 or lower. High-bandwidth Digital Content Protection (HDCP) is a hardware specification created in 2001 by Intel to prevent pirates from copying media and offering it online via torrents. So, what does this have to do with connectivity and this monitor?
Well, previous versions of HDCP (2.1 and under) protected HD content (1080p) and below, but this newest version, HDCP 2.2, which this ViewSonic monitor is equipped with, is geared towards 4K copyright protection. This means that connecting your MacBook, Dell laptop using Windows, or viewing your display or streaming on the big screen from a non-HDCP 2.2 device is going to give you a blank screen. This is because the ViewSonic does not recognize the laptops as a display.
You can still use streaming sites for films, TV shows, music, and so on, but it must be done from the computer itself and not through any devices through the DisplayPorts. The display sharing has some work that needs to be done, because while in theory, all of these connection ports are great, but something as simple as a new hardware update (the HDCP 2.2) can make certain devices incompatible. ViewSonic is hopefully fixing that.
However, to the normal user, this monitor is absolutely amazing and while it has a hardware issue that could undermine some users’ ability to connect, for the mainstream users, it is not a problem.
