[Help] VCP codes doesn't work properly over DP but work on HDMI

[amymor]

MSI G244PF E2
Windows 10 x64 22h2
Installed Monitor Driver

I tested these 3 fallowing tools, none of them work with DP:
winddcutil
ControlMyMonitor
ClickMonitorDDC
But if I connect HDMI everything works.
Also the ControlMyMonitor GUI doesn't show some VCP codes randomly on the DP, I think ClickMonitorDDC shows the values ​​correctly, but the change doesn't affect many values ​​randomly. Let's say I can change the brightness then after a second or two I can't change the brightness and only the contrast is available, the same thing happens for others. Let's say I can change the red and blue lvl of black but cant change the green then I can't change these 3 things related to the black lvl at all.

Examples commands for Brightness 30 Contrast 50 and Black lvl 53:
winddcutil

winddcutil.exe setvcp 1 10 30
winddcutil.exe setvcp 1 12 50
winddcutil.exe setvcp 1 6C 53
winddcutil.exe setvcp 1 6E 53
winddcutil.exe setvcp 1 70 53

ControlMyMonitor

ControlMyMonitor.exe /SetValue Primary 10 30 /SetValue Primary 12 50
ControlMyMonitor.exe /SetValue Primary 6C 53 /SetValue Primary 6E 53 /SetValue Primary 70 53

ClickMonitorDDC

ClickMonitorDDC_7_2.exe setVCP 0x10 30 setVCP 0x12 50 setVCP 0x6C 53 setVCP 0x6E 53 setVCP 0x70 53 q

I use 3 different monitors on my computer, 2 are DP and 1 is HDMI, it took me sometime but this is how I use controlmymonitor to change the brightness and contrast on all monitors, not sure if it will help you;

Day time setup:
ControlMyMonitor /SetValue "DEL428B" 10 90 /SetValue "DEL428B" 12 75 /SetValue "ACR0563" 10 95 /SetValue "ACR0563" 12 65 /SetValue "ACR056C" 10 90 /SetValue "ACR056C" 12 45

Night time setup:
ControlMyMonitor /SetValue "DEL428B" 10 15 /SetValue "DEL428B" 12 65 /SetValue "ACR0563" 10 20 /SetValue "ACR0563" 12 50 /SetValue "ACR056C" 10 20 /SetValue "ACR056C" 12 40

Not sure if this will help you. But thought I would share it.

Thanks for taking the time to reply
I used Hardwire ID like you but nothing changed.
I noticed that the documentation mentions that DDC does not work for DP cable.

Now I am using the following setup:

Although the source is set to DP, the DDC codes work as before, I think in this case the codes are sent via HDMI cable.
