Hi Dell-Zohaib R first of all thanks for halping me second i tried most of it and it didnt help. but when i put the hertz of of the screen on 59 hertz the waves disappeared. but when i change it back to 60 hertz the waves apear and in the 59 hertz the half of the screen steal looks a little bad
Check your computer's surroundings. Move away speakers, fluorescent lights, fans, cell phones, radios and other electrical devices that can cause video to get distorted. Temporarily move electrical items away from the computer to determine whether they are producing this issue.
If the coloration disappears, put back one item at a time to determine what is causing the problem.
If the above steps don’t work, try switching to a different refresh rate other that 59-60 Hz and check if the issue remains.
If possible please attach an image of the problematic screen in your reply.
