ViewSonic VX4380-4K with ‘4K’ IPS panel
Back in May 2016 we looked at the Philips BDM4350UC, a model which really appeals to some users due to its size, the glossy screen surface and its IPS-type panel. The ViewSonic VX4380-4K makes use of this same or a very similar panel, housing it differently and using a different set of assistive electronics (there is, after all, a lot more to a monitor than simply a panel). The monitor is large and angular, with a thin bezel all the way around the screen. This is a single-stage bezel design, there isn’t a substantial additional panel border as some models also have. The stand does not provide any ergonomic flexibility to the monitor beyond tilt, but it at least provides a reasonably sized base to support the large screen. The OSD (On Screen Display) is controlled by pressable buttons and a joystick (JOG button) at the rear of the monitor, towards the right.
The monitor features a 42.51” IPS-type panel with 3840 x 2160 (‘4K’ UHD) resolution and 60Hz refresh rate; likely the TP Vision TPT430U3EQYSHM, as seen on the BDM4350UC. The monitor has a specified 1100:1 static contrast ratio, 178°/178° (horizontal/vertical) viewing angles and a very low haze screen surface. In other words the screen is essentially glossy and gives that ‘glossy pop’ to the image with good smoothness to lighter shades, whilst also having a very mild anti-glare treatment to cut back on reflections a bit. 10-bit colour is supported by way of 8-bit + FRC dithering. The backlight is flicker-free WLED, offering good sRGB coverage but no wide gamut support. To further enhance viewing comfort, ViewSonic have also included their customisable ‘Blue Light Filter’ Low Blue Light (LBL) slider which allows users to easily cut back on blue light output from the monitor when desired. A 12ms ‘typical grey to grey response time’ is specified, which will sound rather high compared to what most manufacturers would choose to specify (such as 5ms, for the Philips). Really, though, this is just a fairer and perhaps more realistic if not slightly pessimistic figure that is being quoted so you shouldn’t worry too much about it.
The ports on the monitor include; AC power input (internal power converter), 2 HDMI 2.0 ports, DP 1.2, MiniDP 1.2, DP 1.2 output (for MST Daisy Chaining), 4 USB 3.0 ports (1 with BC 1.2 fast-charging) and a 3.5mm audio output. The monitor also includes 2 x 7W speakers for basic sound output, possibly of decent quality and volume going by the highly unscientific method of looking at the wattage. The monitor can be VESA-mounted as it features 200 x 200mm VESA holes, if you would like to do away with the included tilt-only stand and mount it in a different and perhaps more flexible way.
Further information can be found on the manufacturer’s website. The monitor is currently available in the US for around $900 with wider availability expected shortly. If there is sufficient demand and time permits, we’ll consider reviewing this model.
