It is brighter than average, and it has a contrast ratio slightly better than its rating.Īs Analyst for printers, scanners, and projectors, Tony Hoffman tests and reviews these products and provides news coverage for these categories.
The ViewSonic VG1655 has a typical screen for a portable monitor, a 15.6-inch 1080p IPS panel with rather limited color coverage, making the display more suitable for business than entertainment. Doing Small Screens Right, in the Little Details Many mobile monitors do not include speakers at all the Lepow 15.6-Inch USB-C Portable Monitor, the MSI Optix MAG161V, and the Editors' Choice Asus ZenScreen Touch are a few that do. The takeaway from this? The VG1655 is acceptable for casual video and photo viewing, but photo buffs and videophiles will prefer a mobile monitor with more robust color coverage, such as the Lenovo ThinkVision M14.Īudio from the VG1655's pair of 0.8-watt speakers is soft, but the speakers could prove useful in a pinch. In viewing our selection of test photos, the situation was similar, with slightly muted reds and greens.
This was true in both the monitor's default mode and in its Movie mode. In looking at video with the VG1655, the effects of this limited color gamut were visible in that reds, purples, and greens frequently looked a bit dull. The white boxes show where the data points would be for a monitor that covers the full sRGB space, and the circles represent our own measurements. The triangle represents the colors that comprise sRGB-essentially, all the colors that can be made by mixing different percentages of red, green, and blue. In our color-coverage testing, the VG1655 nailed just 61.1 percent of the sRGB color space (see the chromaticity chart below). I measured its contrast ratio at 1,040:1, a tad better than its 1,000:1 rating. ViewSonic rates the VG1655's maximum luminance at 250 nits (candelas per meter squared) in our testing, it came very close to that, coming in at 245 nits. I did our brightness, contrast, and color-gamut testing using a Klein K10-A colorimeter, a Murideo SIX-G signal generator, and Portrait Displays' CalMAN 5 software.
Testing the VG1655: Bright Panel, Muted Colors ViewSonic backs the VG1655 with a solid three-year warranty. Colors were only minimally affected by looking at sample images at extreme off-center angles in our testing. In all, it's much better to finagle than most mobile-monitor display schemes.Īs is typical of IPS panels, the VG1655 offers broad viewing angles (rated at 178 degrees for both vertical and horizontal). The choices change depending on where you are in the menu system. To the OSD's right is a diagram of the controller, showing what each press of the joystick will do.
That's a desktop-monitor-style selection in a portable monitor.
The six items in the main menu are Input Select (HDMI or USB Type-C), Audio Adjust (Volume and Mute), View Mode (Office, Movie, Mac, Mono, Game, and Off), Color Adjust (Contrast/Brightness, Color Temperature, Color Space, Color Range, and Gamma), Manual Image Adjust (Sharpness, Aspect Ratio, Overscan, and Blue Light Filter), and Setup Menu (with a wide range of options). While some mobile monitors include a bare-bones OSD with few options beyond changing brightness and contrast, the VG1655 has a full, neatly organized display, the rival of many desktop OSDs.
It is highly recommended to always use the most recent driver version available.
