Gaming Lag on HDMI Input Channel

1. Lower game resolution and frame rate requirements

   • Reduce the resolution from 4K to 1080p on your device to lessen signal processing load, which can sometimes improve input lag.

2. Disable HDR output on the device

   • HDR triggers additional image processing in the projector, potentially increasing latency. Try turning off HDR in your display settings to see if it helps.

3. Turn off keystone correction

   • Keystone correction uses GPU resources for real-time image warping and resampling, adding several milliseconds to signal processing and increasing input lag. Disabling it can reduce delay.
