Hi, I am still having this issue with my Samsung odyssey crg5 that makes a high pitched noise I have messed around with all the settings and still makes the same noise. Is there any other suggestions?

@scholten sounds to me like your monitor is experiencing a form of coil whine. Usually you can decrease this by changing the GPU settings on your monitor. i.e. brightness, color temp, etc. Also, try different inputs and see if that makes a difference. If not, open it up and see if you can determine which coil (or other component) makes that whining noise. There is a possibility of decreasing it by using some thermal pads etc. Once you know where the whine comes from, post some good images of that area with your question Adding images to an existing question
