Ananta 17.3-inch Touchscreen Portable Monitor Review: Huge Screen, Small Size

Well balanced. For a portable monitor, the Ananta integrates more ports and OSD features than expected. There's not a lot to dislike about the monitor especially when compared to other portable monitors out there on Kickstarter.

Currently in its Kickstarter phase, the Ananta 17.3-inch portable monitor promises to be one of the few in its size class to offer touchscreen capabilities in a very thin form factor. The manufacturer claims it to be a "powerful" tool for artists, designers, photographers, business users and even gamers.

Additional specifications and details on the Ananta monitor can be found here.

Connectivity

There are more ports here than most other portable monitors. One USB Type-C port is dedicated for power while the other is for data and video. If connected to a PC via HDMI, the touchscreen or USB-A port on the external monitor will be disabled; users must connect to a PC or smartphone via USB-C in order to activate these specific features of the monitor.

The three buttons along the right edge for the onscreen display settings are firm with great feedback when pressed.

Accessories

The following are included in the box. Interestingly, there is no user's manual.

  • 15 W AC adapter
  • USB-A to USB-C cable
  • USB-C to USB-C cable
  • Active stylus pen (w/ AAAA battery)
  • Remote control (w/ button battery)
  • Protective case
  • Plastic stand
  • HDMI cable

Display

Display quality is excellent and comparable to many mid-range multimedia laptops. Contrast ratio is respectable at approximately 900:1, colors are deep, and response times are decent. Its main drawback is the relatively dim backlight of only 245 nits compared to 300 nits or higher on most laptop displays. Expect some glare from the glossy display if in a brightly lit room or office. It's definitely not an outdoor monitor despite the portable nature.

Another drawback is the backlight bleeding as shown by our image below. The light bleed is unfortunately noticeable when watching movies or videos with black borders.

* ... smaller is better

Color space is wide for a portable monitor. The Ananta covers sRGB in its entirety compared to 60 to 70 percent on most other portable monitors for deeper and potentially more accurate colors.

Further measurements with an X-Rite colorimeter reveal an overly cool color temperature out of the box. Calibrating the panel ourselves addresses this to improve both grayscale and colors noticeably. We recommend applying our calibrated ICM profile above or playing with the preset color settings through the OSD to get the most out of the display.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
26.8 ms ... rise ↗ and fall ↘ combined↗ 18 ms rise
↘ 8.8 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 54 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (24.4 ms).
       Response Time 50% Grey to 80% Grey
38.4 ms ... rise ↗ and fall ↘ combined↗ 20 ms rise
↘ 18.4 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 636 (maximum) ms. » 41 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (38.7 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 24510 Hz ≤ 20 % brightness setting

The display backlight flickers at 24510 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 24510 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17520 (minimum: 5 - maximum: 2500000) Hz was measured.

Emissions

Temperature

Expect surface temperatures to be around 32 C nearest the USB-C ports. This is much cooler than what we recorded on the recent C-Force C-SMART.

Speakers

Audio quality is decent considering the thin form factor and light weight. We had anticipated the volume to be too low, but we find it to be good enough for Youtube videos and gaming. Bass is poor as expected meaning these speakers should be a last resort for music and movies.

Stereo speakers face toward the rear instead of the front, so audio can seem muffled

Energy Management

Power Consumption

The monitor consumes about 4.7 W when on the lowest brightness setting and 12.6 W when on the highest brightness setting. It requires more power than what most USB-A ports can provide and so we're glad that the packaging includes an AC adapter.

It's possible to have just one USB-C cable for both power and display if your PC or smartphone supports it. However, expect brightness to be a little dimmer and battery life to drain more quickly on your laptop or smartphone.

Pros

+ thin, light and portable for a 17.3-inch touchscreen monitor
+ rigid build quality; edge-to-edge glass front
+ both HDMI and USB-C connectivity
+ easy-to-use onscreen display
+ remote control included
+ high quality IPS display
+ full sRGB coverage

Cons

- black-white and gray-gray response times could be faster
- stand doesn't grip well if angle is too shallow or wide
- speakers fire from the back instead of the front
- PWM present at lower brightness levels
- poor color temperature out of the box
- moderate uneven backlight bleeding
- no 144 Hz option

Verdict

In review: Ananta 17.3-inch Touchscreen Portable Monitor. Test unit provided by Ananta
In review: Ananta 17.3-inch Touchscreen Portable Monitor. Test unit provided by Ananta

We've tested a fair number of portable monitors thus far and most of them have been unimpressive. Many would have brightness issues, limited OSD features, limited port options, and even hardware issues like non-functioning SD card readers or unresponsive buttons. Thankfully, this Ananta monitor exhibits none of these problems to be one of the better and more reliable options. It's surprisingly lightweight considering the screen size and it still manages to integrate desirable features like touchscreen support, multiple port options, full sRGB coverage, and even stereo speakers.

We would like to see 144 Hz options, a brighter backlight, and faster response times in the future to attract a wider gaming audience. The stand is somewhat finicky and the backlight bleeding could also be improved. Repositioning the speakers to face forward instead of backward would almost certainly improve audio quality as well. Otherwise, there's not much to complain about the core features, ports, and performance of this monitor.

After graduating with a B.S. in environmental hydrodynamics from the University of California, I studied reactor physics to become licensed by the U.S. NRC to operate nuclear reactors. There's a striking level of appreciation you gain for everyday consumer electronics after working with modern nuclear reactivity systems astonishingly powered by computers from the 80s. When I'm not managing day-to-day activities and US review articles on Notebookcheck, you can catch me following the eSports scene and the latest gaming news.
