The JMGO N1 has a manufacturer's rated brightness of 800 CVIA lumens. Wait, hold on one minute. What the heck is a CVIA lumen? CVIA stands for Color Volume Image Area, which considers a color and brightness combination when calculating a lumens rating, providing buyers with a more in-depth examination of the projector's performance. While ANSI lumens are a calculation of overall brightness, CVIA lumens incorporate a projector's color precision into the formulation.
So which measurement should you take into consideration? The answer is, "It depends." I think it is critical to consider where and how your projector will be used. In a more traditional business, education, and home theater use, I recommend looking at a projector's ANSI lumens rating to help you make a purchase decision. These traditional environments focusing on brightness will ensure you have the best chance of your projector looking its best.
Theoretically, CVIA lumens rating will help customers make a purchase decision, or that's how I understand it. Also, this is a gross oversimplification in an attempt to provide a concise explanation.
Sadly adding a CVIA lumens standard into the mix only increases an already growing number of competing brightness standards that industry experts and users must consider when making a purchase decision. However, ANSI lumens is still the global de facto standard for measuring projector brightness. In addition to ANSI, users are quoted Standard, LED, and CVIA lumens. To say it's confusing is an understatement.
For this and other reasons, we at Projector Reviews will calculate a projector's brightness rating using the ANSI lumens standard and nothing else.
To get my measurements for ANSI lumen calculation, I set the projector to STANDARD mode, the brightest picture mode, and then took three to four readings about 15-20% from the center of the screen.
The N1 measured 716 ANSI lumens.
I measured each projector's preset picture mode's brightness in both HDR and SDR. The results are in the chart below.
