What are the dimensions of the 6iE custom background image?
6iE Smart Thermostat
The 6iE custom background screen is 3 1/2 inches diagonally. However, image scaling is not required thanks to auto-scaling when you upload your custom background.
Tips: Make sure the image you use has a 4:3 landscape aspect ratio (standard camera aspect ratio), to avoid the image being stretched when we scale it. We accept jpg, png, HEIC. Not PSD etc.
