; Some board have i2c communication problem between FPGA and HDMI chip making OSD (and even core itself) laggy.
; This option reduces amount of i2c communication by removing SPD packet change from specific events.
; Note: SPD packets are most important if you use Direct Video mode together with external scaler which
; supports MiSTer specifically. If you don't use such scaler or don't use Direct Video mode then it's safe to set
; this option to 3
; 0 - normal SPD work (default).
; 1 - Don't send SPD in normal mode (non-Direct-Video).
; 2 - Additionally don't send new SPD upon OSD open/close
; 3 - Don't send SPD at all.
