In general smart projection, the trapezoidal correction function has little left and right reminder correction function. At present, the mainstream is the vertical trapezoidal correction of ±40°, and only high-end smart projectors with more than 10,000 yuan have the horizontal trapezoidal correction function. Therefore, it is very shocking to have horizontal trapezoidal correction for the polar meter Z4 aurora configuration because of the high cost. For a smart projector that sells for only 3,999 yuan, it is a sincere attempt to create a product that is very popular among users.
How to do vertical and horizontal trapezoidal correction? Just remember that "where not tune is where", the mouth is: left high right low-key left, right high left low-key right; upper width lower narrow upper tone, narrow upper narrow lower tone.

Since the horizontal correction of the Polar A4 Aurora Smart Projection needs to be implemented with software and special hardware, the Z4X cannot obtain this function through a firmware upgrade.
