JMGO N1 Ultra 4K projector review: Project stunning 4K images on the ceiling and anywhere thanks to gimbal design

The connections can be counted on one hand, but include everything necessary for a projector: The Jmgo offers two HDMI ports, one of which supports eARC.

To the left of this is a USB-A port, which is suitable for connecting Fire Stick, Roku TV, Apple TV, etc. as well as external storage media. However, we were unable to access these in any of our tests with four different storage media. Although they are recognized, the content cannot be accessed. Instead, you are given the option to format it, in which case it can only be read on the projector (not even by the PC), and you can store apps and videos on it. The audio jack is located to the right of the HDMI ports.

It is good that the power connection has been integrated into the stand, which means that the cable does not become a problem when turning and tilting the projector. Unfortunately, the same does not apply to the HDMI, USB-A, and audio connections, which are all located at the back of the projector.

The packaging is made of Styrodur-like material and also serves as a practical carrying bag with a handle. However, the very small plastic closure makes you wonder whether you can really entrust the expensive projector to it in the long term.

In addition to the usual paperwork, a remote control (without 2x AAA batteries), the mains adapter, and a small hexagonal wrench are also included.

The manufacturer grants a standard guarantee of 1 year.

In principle, the projector can also be used without Google - even if this doesn't really make sense, at least you are not forced to do so. You connect connect to a network via WiFi. When setting up WiFi, an energy-saving tip appears with the information that WiFi can consume more energy - a bit absurd for an Android TV projector that is definitely designed for WiFi use. If you do not log in to Google Play, there is only a very limited selection of apps available.

Once registered, you have much more freedom thanks to the Play Store. Netflix is one of the few apps not included, as with many other projectors, but you can install it in other ways or add it externally. The home screen can be configured and customized as desired. Apps can be installed later if they appear in the app list.

The usual app suggestions appear in the overview on the home screen, but we didn't see Prime Video, for example. However, we quickly found what we were looking for by searching - installation and registration worked well.

The settings menu appears on the right-hand side and is quite extensive overall. Although the menu structure is mostly clear, it is confusing that there are the projector settings in the main menu and the device settings separate. These could have been combined in one menu, as it is not always logical which picture settings are in one menu or the other.

Thanks to the automatic image adjustments and optimizations, the image quality makes an excellent impression right from the start, especially the sharpness is impressive. The projector also adapts to new alignments much faster than many of its competitors. The image is realigned almost instantly and perfectly as soon as you turn or tilt the projector to change the alignment - great! The correction sometimes doesn't work for smaller changes. If the projector has to project at an angle, the sharpness naturally decreases slightly towards one of the extreme sides.

The manufacturer specifies 2,200 CVIA lumens, the equivalent of ANSI lumens for the Chinese market. In contrast to ANSI lumens, factors such as color temperature and ambient light are also included in the test conditions, but only very roughly. Depending on the source, a search will show that the figures are slightly higher than the ANSI lumen value (e.g. formovie.com) or roughly comparable (e.g. Heimkinoraum.de).

The brightness is maximized in the standard settings, which can be reduced, but there does not appear to be a dedicated eco mode in the menu. Overall, the picture is quite bright, but only in darkened rooms. In daylight, the display drops significantly, especially in dark scenes.

The coloring is set to cool in the factory setting, but changing to Standard or Vivid in the settings brings significantly more warmth to the image and makes the colors look better. Nevertheless, the projector is rather sparing with the colors overall, for our taste they could pop a little more. The saturation can of course be increased in the settings. Overall, we admire the sharpness, but subjectively there is still room for improvement in the colors.

A word about the rainbow effect: it is definitely noticeable on the JMGO N1 Ultra. Some people notice the effect more than others. In our case, we only noticed the effect when we moved our heads quickly, for example when we moved our eyes from one side of the screen to the other. We personally didn't have a problem with this, but we did notice it nonetheless. The camera captures the effect excessively under a certain shutter speed, see photo.

Officially, the projector supports a color space of 110 percent BT.2020, also known as Rec 2020. We measured that sRGB is almost completely covered, and Display-P3 and AdobeRGB are still covered by around 92 percent.

When operated on a laptop via HDMI, the color deviations are average to high, as is typical for projectors. Calibration under the standard settings for brightness and contrast does not bring any significant improvements here. You should recalibrate the brightness and contrast manually to improve the gamma value and black level. Perhaps you will then also achieve the advertised DeltaE of less than 1, but photo and video editing will probably not be done on the projector.

The projector is incredibly quiet. According to the manufacturer, the operating volume remains below 26 dB. We can confirm this for the most part. In the vast majority of cases, it doesn't get louder than around 23 dB, even after more than half an hour of YouTube use.

It only actually gets louder very briefly when we switch the projector on, where the fan volume reaches a maximum of 27 dB for a few seconds. However, as soon as the projector is fully booted up, it reduces again to a barely audible 23 dB.

The beamer heats the most at the rear, where the warm air is blown out of the interior. We measured hot spots of around 40 °C. The maximum temperature at the front is just over 30 °C, while we only measured 25 °C at the sides of the case.

When switched off, the consumption is only 0.3 W. However, it is also possible to switch the projector to standby. It is not entirely clear which functions are still active, but here the N1 Ultra consumes an average of 15 W, which is clearly too much!

When switched on, the consumption depends on the selected brightness. At full brightness, the average consumption is 128 W. If you set the brightness from 10 to 5 in the menu, the consumption drops to around 75 W.
