    Yeah it comes with 2 HDMI it would seem. Kinda sucks that theres no dual DP for 144hz... Anyway, I have only tried DP.
    btw, my K S works with 144hz via single DP 1.4 from RTX3090

    I will ask the moderators, if the CG437KS model supports the rgb feature in light sense!

    It's advertised as supporting it.

    I have been in contact with support and they said they escalated it, since then I have not heard anything.

    Yeah it worked on my 10-series too after an update, but only with ycbcr422 which means ugly text..

    Mine works single DP 144 Hz with RGB. I think K S is updated to support 144 Hz via single DP.

  • I'm also waiting for a response from the moderators.

    It has now been a week since the last response.
    Time's up, and the screen can't be returned anymore.
  • I will invite moderator @Acer-Ingrid to participate in this thread. Maybe she can tell if this monitor is capable of playing rgb in light sense program.

    Guys, there is a new version of RGB Light Sense - 1.1.7.0 ... Doesn't work for me though. Have you tried?? Do your computers at least make any sound whenever you connect your monitor via USB (the new connected device Windows sound)? Also it does not appear under connected devices list when I use the command line Get-PnpDevice -PresentOnly | Where-Object { $_.InstanceId -match '^USB' } in Windows PowerShell - see the screenshot. Could those of you having the same problem check if their computers are not recognizing the monitor via USB either? Try that command before you connect the monitor and then again after you connect it. For me no additional device appeared. Thanks

    Same. Doesn't work.

    yes my monitor is detected fine for all other tasks like USB-hub and changing monitor brightness.


    Nothing from acer support mail still.

    Guess we got broken monitors.

    In this case my monitor is broken for sure. Maybe I'm missing something but my USB-hub does not work... Which cable did you use for the connection? The USB B 3.0 right? Do you have to adjust some settings in display's OSD to get the USB to work? Thanks

    update: changed source from USB C to USB B in the OSD and now everything works. Including Light Sense :D

    Yes, the USB-B to USB-A connection is required to allow the monitor to act as a hub, and for any data connections other than video.

    Of course it is :D but I didn't know you have to change the type of connection in OSD

    What a journey we've had together my friend!!

    At first when I read that you got it working, I was sad. I thought I'd be left alone here.

    See before I tried all options of USB mode, both types of cable, all the modes in "lighting" category... etc.

    But it looks like this last light sense update fixed it. But when I tried it, I just used a couple of options and didn't try them all.

    But right now it works for me too. Here's the settings:

    • system - lighting - lighting switch - set to "Enable" (Not "PC", very weird.)
    • system - USB Port Select - "B-type"
    • system - USB 3.0 - "On"

    I wont try the other settings now because I'm scared it wont work.

  • Can you post the link of the rgb sensor you downloaded?
