Yes, this is normal behavior. Any other setting would negatively impact latency and increase lag, and will directly disable GameMaestro mode to reset keystone value to “0”, set the aspect ratio to “Auto”, and return to picture mode you set before. In other words, GameMaestro mode will be disabled once the following are applied:
1. Picture mode switched to any mode other than GameMaestro
2. Aspect ratio set to auto
3. Keystone is adjusted manually
4. Auto keystone is enabled
