I have two DLPDLCR2000EVM for evaluation purpose.
I have setup both with of them with different Raspberry Pi 4B.
One of them successfully mirrors Raspberry Pi screen however on the other one, despite same settings (in one I am using female to female connection which works fine, one with male to female connection is failing) I am getting following error.
Following is the setting on raspberry pi:
# Enable audio (loads snd_bcm2835)
dtparam=audio=on
# Automatically load overlays for detected cameras
camera_auto_detect=1
# Automatically load overlays for detected DSI displays
display_auto_detect=1

I am running following command in rc.local
sudo i2cset -y 22 0x1b 0x0c 0x00 0x00 0x00 0x15 i
sudo i2cset -y 22 0x1b 0x0b 0x00 0x00 0x00 0x00 i
Please help if I need to change clock frequency what should it be?
Secondly I am not able to send command to turn projector on and off.
