FAQ: Automatic Keystone Correction

Is there a plan to make the keystone correction manual ? I know there is the 4-corners correction available, but this is not working in hdmi (and HDMI will be the long term usage).

What is the solution (or even hack) if the wall is not straight to have a correction with HDMI ?

This is the first time I learned that calibration is done everytime automatic keystone correction is toggled. I don’t think that’s a good behavior especially that it’s the only way to completely disable 4 corner correction and improve the performance. I toggle it quite often when I’m switching between external and internal source. I feel like the toggle has 2 inappropriate functions know - disable 4 corner and calibration.
