MPG 341CQR QD-OLED X36: AI Care Sensor and USB power cycling issues... am I missing something?

Hi everyone,
I recently purchased an MSI MPG 341CQR QD-OLED X36 monitor. While I am absolutely loving the image quality, I am running into a few issues with its additional features, which are making the overall experience less than smooth.

Specifically:

1) AI Care Sensor (in Monitor Mode): the sensor only seems to detect my presence if I stay within a maximum of 50 cm from the screen. If I simply lean back in my chair, moving to a distance of around 70 cm - which is a perfectly natural viewing distance for a monitor of this size - the screen shuts off. This happens even in a well-lit room. Needless to say, this feature is almost unusable like this. Is my unit/sensor defective, or is this its "normal" behavior? Is this something that could potentially be fixed in a future firmware update?

2) Built-in USB Hub: I turned "Type C PD Charge" ON so that the monitor USB ports stay powered on even when the monitor goes into standby. However, all USB ports still get shut off and then back on when the monitor wakes up from an inactivity standby. This is particularly annoying because I have my mouse and keyboard connected to the monitor for the KVM functionality, causing me to temporarily lose control of them every time the screen wakes up. Is there any way to prevent this power cycling from happening? Interestingly, I noticed it doesn't happen when the monitor wakes up after being turned off by the AI Care Sensor. Again, assuming there's no current workaround, is a fix via a future firmware update likely?

Thanks in advance for any insights or suggestions!

If everything works fine within 50cm, I would think it's just the hardware limitation. Though I don't see any documentation about this.
Type C PD Charge should only affect the Type C port which allows it to charge device up to 98W, it shouldn't affect other USB port behavior.

Regarding the AI Care Sensor, if it's actually supposed to only work within ~50 cm, I'd consider it a very poor design/engineering choice, especially for a 1200$ 34" ultrawide monitor. That's why I was hoping it was something I could fix on my part (through configuration or RMA if necessary), and not a baseline hardware limitation.

As for the "Type C PD Charge" setting, that's exactly what I thought at first too—that it would only dictate whether the USB-C port keeps delivering power to charge devices while the monitor is in standby. However, through testing, I noticed that its behavior actually extends to the rest of the USB hub: when "Type C PD Charge" is set to ON, all the USB ports remain powered and active while the monitor is in standby, while if I turn it OFF, all USB ports lose power as soon as the monitor goes to sleep. So in practice, it acts as a toggle for keeping the whole USB hub alive during standby, which is why the power cycling upon wakeup is so frustrating.

Can you provide more and full details how this issue can be reproduced?

Sure.

1) AI Care Sensor
Monitor firmware version: FW.015
Monitor settings:
* AI Care Sensor > ON
* AI Care Sensor > Active Mode > Monitor Mode
* AI Care Sensor > Wake on Approach > ON
* AI Care Sensor > Wake on Approach > Timer Setting > 0
* AI Care Sensor > Lock On Leave > ON
* AI Care Sensor > Lock On Leave > Timer Setting > 0
* AI Care Sensor > Adaptive Dim > ON/OFF
* AI Brightness: OFF
* AI Light Sensor: OFF

How to reproduce the issue:
As long as I stay in front of the monitor at a distance of no more than 50 cm, the screen remains on. As soon as I lean back in my chair, moving at around 70 cm from the monitor (but still directly in front of the sensor), the monitor turns off within 10 seconds. If I move back within 50 cm, the monitor turns back on. This happens under all lighting conditions: full/dim light, artificial/natural light.
The Adaptive Dim setting doesn't affect the behavior mentioned above, but that feature appears to be quite imprecise and unreliable on its own: the screen often lowers its brightness even though I have never stopped staring directly at it, always no more than 50 cm from the screen.


2) Built-in USB Hub power cycling
Monitor firmware version: FW.015
Monitor settings:
* Type C PD Charge: ON

How to reproduce the issue:
In Windows, under Settings -> System -> Power & Sleep -> Screen, set to turn off the screen after X minutes of inactivity. After X minutes of inactivity, the monitor turns off and goes in standy as expected, leaving the devices connected to its USB-A ports (keyboard and mouse in my case) powered on. Moving the mouse or interacting with the kayboard interrupt the standby and make the monitor wake up, but doing so the monitor power cycles its USB ports, turning them off and then back on, as demonstrated but their RGB lightning going off and back on, Windows USB disconnection and reconnection sounds, and the inability to use them for a short period after the wake up.
The USB ports power cycle doesn't occur when the monitor turns off and back on due to its AI Sensor Care feature.

For the USB Hub power cycling, if you only connect one device via KVM, can you disable Autoscan, and only check your input source in KVM option?
Just to make sure the monitor doesn't try to scan through all the port which might cause the power cycling.

Good idea, unfortunately it didn't work out: it stills power cycles the USB ports...
