No display signal

Pc works fine, tried other display, sent it to a store to diagnose it, he called me back saying it was working perfectly.

Tried it on same displays again, same thing, no display signal.

Tried another pc, same displays, working smooth.

Build is
MSI B550 a-pro
Ryzen5 5600x
Stock cooler
Corsair 16gb X 2
A-Data nvme m.2 512gb
Samsung 750evo 250gb
Seagate barracuda 300gb
GTX 980ti
ASUS XONAR ESSENCE STX II
PSU antec 80 bronze 650W

Display is MSI optix MAG341CQ curved 34”

Im frustrated, reseated everything 3 times and nothing.

Any ideas please?

you said that you tried another PC with the same display. what is the gpu on that PC?

edit:
the only thing I can think of is that the usual port you use is probably bad or disabled, and the store person used a different port

Yeah thats the case, i used the hdmi port, the store used the same gpu but the dvi port.

The other pc has integrated gpu, i used that pcs mobo hdmi port. Didnt try the dvi port, will try it too.

damn sorry I hope your card is not going out

I’m very suspicious of video card HDMI ports. I got a brand new HDMI 2.1 cable for my PC and I got the dreaded black screen flicker. No problems with my DisplayPort.
