Every e-ink panel is a little different. What looks perfect on one display might feel cramped or oversized on another.
Where to find this feature?
Navigate to Device > Edit > Device Model (only visible for BYOD devices):
Pixel Ratio (0.5–3.0)
Zooms the entire image. Like pinching to zoom on your phone.
Below 1.0 = zoomed out, more content fits
Above 1.0 = zoomed in, content is larger
UI Scale (0.5–2.0)
Adjusts text and element sizes without changing the overall image dimensions.
Below 1.0 = smaller text, tighter spacing
Above 1.0 = larger text, more breathing room
Which one should I use?
Everything looks too small → Increase Pixel Ratio
Text is hard to read → Increase UI Scale
Layout feels cramped → Increase UI Scale
Image doesn't fit the screen → Adjust Pixel Ratio
Force Refresh after update
Screens are pre-rendered images. Changing calibration settings only affects new renders.
After saving your changes, go to your plugin and hit Force Refresh to regenerate screens with your new settings. Otherwise you'll keep seeing the old cached images.
Reset to defaults
Click Reset to defaults above the calibration fields to restore the original values for your device model.
