Doesn't allow controlling my monitor, but GetBrightness+SetBrightness works in log

[Terrobility]

My monitor is a MSI G273QF connected over DisplayPort. I checked the probe log and this is what it says:

"Description": "MSI Optix G273QF",
"MonitorIndex": 0,
"Capability": {
  "IsHighLevelBrightnessSupported": false,
  "IsLowLevelBrightnessSupported": false,
  "IsContrastSupported": false,
  "IsPrecleared": false,
  "CapabilitiesString": null,
  "CapabilitiesReport": null,
  "CapabilitiesData": null
},
  "GetBrightness": "Success: True, Valid: True (Minimum: 0, Current: 35, Maximum: 100)",
  "SetBrightness": "Success: True, Match: True (Expected: 40, Actual: 40)"

So clearly the GetBrightness and SetBrightness is working. But because the capability is reporting as False, the app isn't allowing brightness control. Or at least that's my guess.

I tested with another DDC app and the brightness CAN be controlled (as well as contrast, color temp, etc.). So this is definitely a Monitorian issue.

Thanks for reporting.
Your monitor seems to have an issue for reporting its capabilities.
In such case, you can use preclear option

It worked, just wanted to note that the [Device Instance ID] argument must NOT be surrounded by any quotes. e.g. /preclear DISPLAY\\MSI3CA8\\5&348a04ab&0&UID4354

[emoacht]

Yes, it may or may not be surrounded by quotation marks when it is given by command-line. Quotation marks will be removed by the OS.

I'm not sure about command line but in the Monitorian hidden menu, it doesn't work when surrounded by ""

[emoacht]

No, it does not.
