“The VP2780-4K offered a very good all-round screen with a robust and sturdy design and feature set. The versatile stand, wide range of connectivity options and useful extras like USB 3.0 ports and PiP/PbP were pleasing, and showed that ViewSonic continue to offer high end features from their VP series. The design of the screen is fairly industrial and perhaps lacks the wow factor of some alternative designs in the market. Maybe the stand needs a bit of a refresh in the future? However, it is solid and reliable and will no doubt suit a lot of people's taste all the same.
This is the first of their VP range to offer Ultra HD 3840 x 2160 resolution, and it does this well - offering 60Hz refresh rate support over both DisplayPort and HDMI 2.0. As ever with super high resolutions like this you need to keep in mind the support for effective scaling from your operating system and applications. You also need to consider the demands on your graphics card when it comes to multimedia uses at such a high resolution. The high pixel density on a 27" screen size provided a sharp and clear image which is the main aim of course.
In other performance areas the factory calibration provided a decent default setup with reliable gamma, white point and a strong contrast ratio. You don't have the option of wide gamut support on this model like the previous VP2772, so keep that in mind if you wanted to work with wide gamut content. The flicker free backlight and light AG coating were welcome as ever and although the response time was slightly slower than other 60Hz IPS panels it was still pretty decent, and at least free from noticeable overshoot. The display lag was also pretty low and so the screen could be a reasonable option for Ultra HD gaming on an IPS panel at the moment. There were only really a couple of minor performance negatives we felt. We would have gladly sacrificed a bit off the top end of the very high brightness adjustment range for the sake of a bit more control at the lower end in an ideal World. Also there wasn't an aspect ratio option to maintain the source aspect but fill more of the screen. You have 1:1 at least, but we would have liked this additional option. Overall though we are picking a bit and the screen impressed us with very good all-round performance and a wide selection of extras.”
