Question Can't boot up when DVI or HDMI is plugged in to my new monitor ?

[Bluegori]

Hello, greetings from Indonesia i have some issue with my new monitor, maybe someone can help?

So yesterday i bought a new monitor its Armaggeddon xc27hd, the problem is when i connect DVI or HDMI to my GPU the PC wont boot, Processor and fan case seems to light up but the mouse and keyboard doesn't. Then i tried to remove the cable and tried to boot without it and it works, all the lights are on. Once its boot up i can plug the cable and its shows display

I can boot without any problem using the previous TV ( LG )

Spec :
Mobo : Asrock B450m Pro 4
Procie : Ryzen 5 2600
GPU : GTX 1050 TI 4GB
RAM : Corsair vengeance 2x8Gb @2666Mhz
PSU : be quiet! System Power 8 400w Bronze

Thanks in advance, cheers fellas

When you speak of the older TV, how is it tethered to your system? The only thing I see that might be preventing you from booting up might be that you're suffering from a grounding issue. How old is the PSU in your build?

sorry, what do u mean by tethered? i used HDMI for my old TV since there's no port for DVI

I bought the PSU back in 2018 but so far there's no issue with my PSU, except for this new monitor. had to remove the HDMI or DVI until it boot up then re-connect it again
