[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
