Monitor keeps turning off and on repeatedly

So i bought a dell monitor and it worked for 7 months but one day it just started turning off and on. It just randomly turned off and then back on instantly and after that it did it repeatedly. I plugged it in other computers and with different display cables but it still did it. The monitor works for 20 minutes and after that it starts turning off and on. I got the same model new monitor from dell warranty but the problem did not stop, it kept going. I plugged it in amd and nvidia graphics cards, with vga and hdmi cables, to a laptop and to a desktop computer. I plugged in a different dell monitor to my computer and it had no problems and i plugged in a benq monitor and still no issues, but as soon as i plug my dell se2416h monitor to my computer it started turning off and on after 20 minutes. I even tried uninstalling graphics card drivers and different power cables and nothing works. I have windows 10 and i hope i will get some help, because i'm losing my mind

Best regards,

Tom
