DLPDLCR2000EVM: DLPDLCR2000EVM with Raspberry Pi 4B not displaying Pi screen

Part Number: DLPDLCR2000EVM

Hi,

I have followed steps mentioned on following page to connect Raspberry Pi 4B with DLPDLCR2000EVM.

https://www.mickmake.com/post/build-a-pi-zero-w-pocket-projector-project/

Some of the connections that I couldn't make sense of : PROJ_ON_EXT, HOST_PRESENTZ and GPIO_INIT_DONE.

Can you please help me with how to connected Raspberry Pi 4B with EVM. 

Currently getting following output

i2cdetect -y 22

     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f

00:                         -- -- -- -- -- -- -- -- 

10: -- -- -- -- -- -- -- -- -- -- -- 1b -- -- -- -- 

20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 

30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

50: -- -- -- -- -- -- -- 57 -- -- -- -- -- -- -- -- 

60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 

70: -- -- -- -- -- -- -- --

Moreover if I try , nothing changes on the display. I keep getting the default display that projector shows on power on. 

pi@raspberrypi:~ $ i2cset -y 22 0x1b 0x0b 0x00 0x00 0x00 0x00 i

pi@raspberrypi:~ $ i2cset -y 22 0x1b 0x0c 0x00 0x00 0x00 0x1b i

I have connected 5V from Raspberry Pi to projector.
