The Model is Samsung S43BM700UM. I bought it and using it for a year, I guess it's stillunder warranty for 6 month!Likely a hardware issue.
Monitor model?
Age?
If it is still under warranty, contact Samsung.
I see, Ok i Will ask the company if they accept it or not, Thank you very muchIf you start the RMA process now it doesn't really matter what happens to it in the meantime as long as you do no intentional damage.
Not actually, I'm using the original HDMI cable that came with the package, but I have an older and I guess better HDMI cable , I would try! My GPU is RTX 3070, do you think Display port cable is better?Have you tried different video cables/ports?
