How to Adjust the Aspect Ratio of the Projector? How to correct the trapezoid in the picture?

  • 1、The aspect ratio can be set after the projector is turned on and connected to the computer. Generally, the "aspect ratio" of the 85-inch infrared whiteboard can be set to 4: 3; color correction, brightness contrast, etc. can be adjusted as needed.

  • 2、Keystone correction, simply put, is whether your projected picture is a rectangle. If it is a keystone, first adjust the "Auto Keystone" to the off state, select the "Keystone Correction" above and press the left and right keys on the remote control to adjust to a satisfactory state.
