ViewSonic VX1755 review: A portable gaming monitor with USB-C

ViewSonic includes an HDMI-to-mini-HDMI cable, a USB-C cable, and a USB-A to USB-C cable with the VX1755 as accessories. The mandatory power supply is of course included, as well as a quick start guide and as a special feature, a screen protector cover.

optics and mechanics

From the front, the ViewSonic VX1755 portable monitor is uniformly black. This part of the case is made of plastic, the surface is slightly rough, the border around the screen is only 6 mm wide on three sides – the bottom edge of the screen is 24 mm wide. On the other hand, the case back is silver colored and made of metal. The surface is matte and has a triangular pattern milled into it. The workmanship of the model feels high quality, both visually and tactilely.

The manufacturer’s logo is placed once in the center of the lower display frame on the front and once in the middle of the stand on the back of the case. In both cases, the name of the manufacturer is printed in white letters.

ViewSonic VX1755 body thickness increases from top to bottom. The case is about 9mm thick at the top edge of the screen and about 17mm thick at the bottom edge of the screen. The provided protective cover can be used on the one hand as a base so that the screen is more stable and does not slip, and on the other hand to protect the screen during transportation.

The protective cover is fixed to the top of the chassis by magnetic attraction and thus held in a fixed position.

The ViewSonic VX1755 has a built-in stand, but it can only be used to adjust the tilt of the monitor. The variable height cannot be adjusted, and the monitor cannot be placed in an upright position (axis). Threaded metal hinges ensure stability, and the base is made of metal.

The tilt of the monitor can only be adjusted using the built-in stand. The lowest tilt at which the ViewSonic VX1755 remains stable is about 15 degrees. The screen can be tilted up to 62 degrees.

There is no VESA mount or other attachment to use the optional mount solutions.

Operating noise

The ViewSonic VX1755’s electronics operate silently and cannot be heard from outside. The external power pack also stays on without any audible operating noise, even when the screen is off. Changing the brightness or other settings in the OSD had no effect on the development of noise.

However, noise development in particular can be subject to significant chain propagation, which is why this assessment should not apply equally to all devices in a chain.

The data sheet of the ViewSonic VX1755 contains comprehensive information on power consumption. According to the manufacturer, the maximum requirements are 13 watts and 10 watts on delivery. Typical power consumption should be 12 watts – but what is typical consumption? Our measurements resulted in a maximum of 10.7 watts in the handed state, i.e. without any OSD changes, and with the highest backlight brightness, which was preset to 100% on delivery. All information regarding power requirements was undermined when measurements were made.

The ViewSonic VX1755 also offers an Eco mode with ‘Standard’, ‘Save’ and ‘Enhance’ options. When “Optimize” is activated, the brightness is reduced to 115 cd / m² and the screen consumes 8.5 watts in this case. With the “Saving” option, the brightness is reduced to 80 cd / m², which results in a power consumption of 7.7 watts. A power adapter with no monitor attached will not draw any current. With 1.40 cd/W, the test subject also achieves very good efficiency.

With such low power consumption, one thing is completely missing: an integrated battery. This fact severely limits portable use, as there is not always a power source available to power the display on the go. However, it is possible to power the ViewSonic VX1755 over USB-C or USB-C 3.2 with DisplayPort from a smartphone or laptop.

links

Connections are located on the left side of the case to the ViewSonic VX1755. Mini-HDMI, USB-C 3.2, headphone output, and USB-C power port are available. According to the datasheet, photo signals can also be sent via the USB-C port. Since we didn’t have a device, we could only test it with a smartphone, but that didn’t work. The smartphone is only charged.

Services

The ViewSonic VX1755’s control buttons are located on the right side of the case. There are four switches for power and a button for power.

If one of the four buttons is pressed when the OSD is closed, an icon graphically representing the function of the button will appear next to the respective button on the screen. There is also a text description for each icon.

With the convenience of symbols and text descriptions, there is no longer a need for further explanations about which key is responsible for the function. Thus, the ViewSonic VX1755 allows direct access to pre-set picture modes, contrast, brightness and signal source controls using a dedicated button, without the need to open the OSD. Of course, these options can also be accessed via the monitor’s OSD, but it’s much more convenient that way.

Below the power button is the power indicator. The LED indicator lights up blue when the screen is on and orange when it’s in sleep mode. The playback screen can be deactivated in the OSD, but only for powering on, because the playback screen always lights up orange when idle.
