Hello, I'm trying to setup dlp200evm with raspberry pi 4 b+. the issue I get is:
pi@raspberrypi:~ $ i2cdetect -y 2
0 1 2 3 4 5 6 7 8 9 a b c d e f

I believe it could be fixed with i2cset in combination with hdmi_timings
My config:
# Add support for software i2c on gpio pins
dtoverlay=i2c-gpio,bus=2,i2c_gpio_sda=23,i2c_gpio_scl=24,i2c_gpio_delay_us=2
# DPI Video Setup

sudo i2cset -y 2 0x1b 0x0c 0x00 0x00 0x00 0x13 i
sudo i2cset -y 2 0x1b 0x0b 0x00 0x00 0x00 0x00 i

It works with settings for 640x360 and i2cset -y 2 0x1b 0x0c 0x00 0x00 0x00 0x7 i
Also I read the manual of DLPC2607 Programmer's Guide and tried some settings with no good result.
By the way 0x13 points to 800x480, I also tried that, and 0x19 at the end gives me lines in between...
