The JMGO N5S Ultra Max brings several interesting improvements to the DLP projector market. Its biggest highlights are 4K resolution at 120Hz, VRR support, extremely low input lag, and an adjustable dual-iris system designed to improve contrast.
In this article, we take a closer look at the original video review by Captain Koala, analyzing his measurements, real-world tests, and personal impressions. Based on his findings, we’ll explore the projector’s gaming performance, image quality, contrast, rainbow-effect suppression, and installation flexibility, highlighting its main advantages and disadvantages.
JMGO N5S Ultra Max: Key Features and Specifications
The JMGO N5S Ultra Max is a flagship triple-laser DLP projector built around a 0.47-inch DMD chip. According to Captain Koala, it is the first projector using this DLP chip size to support 4K at 120Hz.

JMGO N5S Ultra Max Performance Tests
4K 120Hz Gaming and Input Lag Performance
One of the most important features of the JMGO N5S Ultra Max is its ability to display 4K content at 120Hz while supporting VRR. This is a significant improvement over previous DLP projectors, which generally offered 120Hz only at 1080p.
Captain Koala tested the projector with both PlayStation 5 and PC gaming. He explains that VRR can make gameplay smoother even when a console cannot maintain a constant 120 FPS. PC gamers can benefit even more from high refresh rates, especially when using technologies such as DLSS and frame generation.
The input lag measurements were particularly impressive:
- 13ms at 60Hz
- 5ms at 120Hz
- 3ms at 1080p 240Hz
According to the reviewer, these results put the JMGO N5S Ultra Max among the best projectors he has tested for gaming. However, there is one important detail: only the left HDMI port supports 4K 120Hz, while the second port is limited to 4K 60Hz.
Rainbow Effect Suppression: How Well Does It Work?
Another interesting improvement is the projector’s ability to reduce the rainbow effect, a common issue with single-chip DLP technology.
Captain Koala performed a high-speed motion test and compared the results with a conventional 4K 60Hz DLP projector. He found that the JMGO N5S Ultra Max produces noticeably lighter colored trails, partly thanks to its faster 4K 120Hz operation.
There is also a dedicated rainbow suppression mode that reduces the effect even further. However, the reviewer noticed visible image noise when this feature was enabled. He considers the standard performance already very good, even without the additional suppression mode.
Brightness and Contrast Measurements
The JMGO N5S Ultra Max is rated at 6,800 ISO lumens / 5,600 CVIA lumens. However, Captain Koala’s testing focuses not only on brightness output but also on how much brightness remains available at different screen sizes and iris settings.
Using his Perceptual Brightness Reference Model, he estimates that the projector can maintain around 100 nits on a screen up to 180 inches at F2.0. At F5.0, this limit drops to approximately 140 inches, while at F7.0, it is around 90 inches.
According to the reviewer, F5.0 offers the best balance, delivering approximately 8,200–8,900:1 contrast while retaining sufficient perceived brightness for a large 140-inch screen.
The JMGO N5S Ultra Max uses a triple-laser light source, providing high brightness and a wide color gamut. However, the most interesting results in Captain Koala’s testing came from its adjustable dual-iris system.
The projector offers six aperture settings, allowing users to balance brightness and contrast.
Here are the reviewer’s measured contrast results:
- F2.0: Approximately 1,600:1–2,000:1
- F3.0: Approximately 2,500:1–3,000:1
- F5.0: Approximately 8,000:1–9,000:1
- F7.0: More than 10,000:1
The F5.0 setting is particularly impressive. According to Captain Koala, it provides the best balance between brightness and contrast, maintaining sufficient perceived brightness for a screen of approximately 140 inches.
At F2.0, the projector can handle screens up to 180 inches while maintaining sufficient perceived brightness, but contrast is considerably lower. At F7.0, contrast increases further, although the substantial brightness reduction makes it more suitable for screens below 100 inches.
Based on these measurements, the reviewer considers F5.0 the sweet spot for everyday use.
Movie-Watching Experience and Image Quality
When testing movies, Captain Koala describes the overall image performance as very good, without any obvious major weaknesses.
The triple-laser light source provides a wide color gamut, while HDR dynamic tone mapping helps prevent HDR content from looking too dark. Dolby Vision support is another welcome addition.
There are, however, some familiar triple-laser limitations. The reviewer noticed slight laser speckle and some color fringing around the image when viewed at certain angles. Minor color fringing is also visible around white text when looking closely, although it is difficult to notice from a normal viewing distance.
Design, Optical Zoom and Installation Flexibility
JMGO retains its familiar rounded design with a refined exterior and wood-grain front panel. The projector also features a motorized gimbal, making it easier to adjust the projection angle.
Captain Koala particularly highlights the wide optical zoom range of 0.88–1.7:1 and extensive lens shift of ±130% vertically and ±53% horizontally. Together, these features provide considerable flexibility when positioning the projector.
Another practical detail is that all connection ports are located on the bottom. This makes ceiling projection easier because connected cables are less likely to interfere with the projection angle.
What Could Be Better
Despite its impressive performance, Captain Koala identifies several areas that could be improved in the JMGO N5S Ultra Max:
- Image Noise: The dedicated rainbow suppression mode introduces noticeable noise, although the standard mode already performs well.
- Laser Speckle: Slight speckle remains visible, which is typical of triple-laser projectors.
- Color Fringing: Minor red and green fringing can be noticed under certain viewing conditions.
- HDMI Limitations: Only one HDMI port supports 4K 120Hz.
- Keystone Correction: After moving the projector, automatic correction may require manual adjustment to restore the original image geometry.
- HDR Menu: The dynamic tone mapping option is buried several levels deep in the settings.
JMGO N5S Ultra Max: Final Verdict
Based on Captain Koala’s testing, the JMGO N5S Ultra Max is a very competitive flagship DLP projector, particularly for users who enjoy gaming on a large screen.
Its biggest achievement is combining 4K 120Hz, VRR, and extremely low input lag. The measured 5ms response at 120Hz makes it an excellent option for gaming, while the large projected image creates a more immersive experience.
The adjustable dual-iris system is another major strength. Reaching approximately 8,000–9,000:1 contrast at F5.0 while retaining enough brightness for a 140-inch screen is an impressive result for a single-chip DLP projector.
Captain Koala also appreciates its effective rainbow-effect suppression, wide optical zoom, extensive lens shift, and flexible motorized gimbal. Although there are some minor image-quality and software issues, they don’t overshadow the projector’s main strengths.
The reviewer considers its price of under 13,000 yuan ($2000) particularly competitive, given the combination of features and performance.
Overall, Captain Koala sees the JMGO N5S Ultra Max as one of the most feature-packed DLP projectors of its generation, with 4K 120Hz gaming and high contrast being its strongest selling points.
