Planar Helium PCT2785 vs ViewSonic XG2700-4K

The black levels are respectively low at 0.16cd/m², which helps the contrast ratio achieve 1100:1 which is much lower than the advertised 5000:1, but still quite good.

The response time is 12ms, which isn't lightning fast, but it's still quick enough to make the system feel more responsive than cheaper monitors. While not fast enough for high-level gaming, this monitor won't make your system feel slow or unresponsive.

It really does look like a massive tablet with a kickstand - but that's not a bad thing. There's no stand visible, leaving the front looking very clean. The stand can angle anywhere from 15-70 degrees which allows for flexible use, or it can be folded in and used flat on the desk or even mounted using the VESA mounting holes.

This monitor has many peripherals built-in, and unless you use them heavily they will do the job just fine. Unless you feel the need for dedicated hardware, the built-in stereo speakers work well enough, and the webcam and mic are acceptable quality for occasional recreational use (for business calls or other uses where quality is important, you'll want to upgrade to dedicated hardware).

ViewSonic takes color accuracy seriously with this monitor, as it is comes calibrated out of the box. The monitor uses a 10-bit panel and can display 99% of the sRGB color range. On top of that, it has almost no issues with screen uniformity, color accuracy and gamut. This makes it great for editing photos, videos and other types of work that require accurate colors.

ViewSonic has equipped this monitor with very generous input options. It has three HDMI 2.0, one DisplayPort and one DisplayPort mini. It also has four USB 3.0 ports, two of which are on the right side of the monitor for easy access.

If needed, the monitor allows you to view from four inputs at once, or to show them picture-on-picture.

Its height, swivel, tilt and orientation can all be freely adjusted, and is attachable to a VESA compatible wall mount or stand.

Input lag is almost non-existent on this screen, at only 9.9ms if the “Extreme” input mode is selected. This makes this monitor among the fastest in the market. Since it uses a slower IPS panel (compared to TN panels), the pixel response time measures just 5ms, which isn’t the best, but is good for most situations.
