The projector adopts black as the main color and has a shining golden color as embellishment. Looking from the front view, we can see the NexiGo logo in a shining golden color and a big lens module at the left side panel.

There are two perforated vents on the two sides to dissipate heat and lower noise. Near the vents there are Filters, and you can clean them every month to ensure a clear image.

Looking from the top view, we can see a combination of keys and a focus slider. The interfaces are located at the back panel. The foot pad at the bottom of the NexiGo PJ40 can raise the image height of the projector.

On the whole, the design of NexiGo PJ40 follows the style of NexiGo’s overall design principle.


The top considerations of the projector’s images are image resolution and brightness. NexiGo PJ40 has native 1080P resolution and supports 4K resolution, whose projection image is crisp and sharp. As for brightness, the projector is rated at 600 ANSI lumens, which is brighter than most budget min projectors under $500 on the market. However, it is still not bright enough for daytime use. It is recommended to use at night or in dark environments. If using the projector with lights on, the viewing effect may be decreased.

NexiGo PJ40 adopts LCD display technology, which is widely seen in budget mini projectors.

In terms of image technique, the projector supports manual focus and auto vertical keystone, but the auto keystone is invalid when the 4D keystone is on.

As for image size, the projector can project at most 300 inches. It supports zoom function, allowing you to adjust the image size of the projector from 60% to 100%.


For wireless connectivity, NexiGo PJ40 supports 5G Wi-Fi and Bluetooth 5.1, enabling you to connect the projector to external devices wirelessly, for example, headphones, or speakers. The wireless Screen Mirroring function is useful as the projector has no built-in smart system.

Some users say that the IOS wireless mirroring may come across failure occasionally, and you can try to restart the projector or your iPhone as there may be a lag. Otherwise, you can update the software of the projector. In addition, please follow the steps on the iOS cast on the projector screen and ensure the projector and your iPhone are connected to the same Wi-Fi Network.
