One of the displayports on my 7900xt stopped working after about 3 weeks of use for some reason. I eliminated the monitor being at fault, I eliminated the cables being at fault, I already tried DDU.

For some reason windows does detect the monitor being plugged in, but no signal. Any ideas?

SPECS:
OS: WINDOWS 10 22H2(just updated) problem occured before update
CPU: Ryzen 9 5900x
GPU: RED DEVIL 7900xt
Motherboard: ASUS TUF x570 WIFI PLUS
RAM:216 3600 CL16 and 28 3600CL16
PSU: RM750
Monitor: ASUS VG1A and ASUS VG275Q,

Left DP FDP DP HDMI Right

In my diagram the FDP is the broken DP, the other ones are working.

fossil dawn One of the displayports on my 7900xt stopped working after about 3 weeks of use ...

are you using more than one monitor?

fossil dawn Feb 1, 2023, 3:48 AM

#

yes, I was using more than one previously, just stopped working

#

fossil dawn yes, I was using more than one previously, just stopped working

i had a similar issue not sure if it will work but try disconnecting both monitors and then just try it with just that one port first

kjk

#

nope

#

didnt work

#

some other symptons is when I do plug in the 3rd monitor i can change the resolution but it lags the computer real bad

#

well plug into the faulty DP cable. not necessarily a third monitor

#

I only use two, I had three for testing

wild cedar Feb 1, 2023, 3:54 AM

#

so each port works just that one?

fossil dawn Feb 1, 2023, 3:54 AM

#

yeah, but I would prefer to solve the issue for peace of mind

wild cedar Feb 1, 2023, 3:55 AM

#

and you know for certain its not the port on the monitor end?

fossil dawn Feb 1, 2023, 3:55 AM

#

yeah I've tested three separate known working monitors along with two different DP cables

wild cedar Feb 1, 2023, 3:58 AM

#

is it just the standard RED DEVIL 7900xt?

fossil dawn Feb 1, 2023, 3:58 AM

#

there are multiple red devils? I beleive it is just teh standard one

wild cedar Feb 1, 2023, 3:58 AM

#

yeah theres a reddevil edition and hellhound edition

fossil dawn Feb 1, 2023, 3:59 AM

#

I believe it is the standard one

wild cedar Feb 1, 2023, 4:00 AM

#

could be a bad port...

fossil dawn Feb 1, 2023, 4:01 AM

#

HDMI is working

#

thats weird unlucky I guess

#

the port was worked for 3 weeks

wild cedar Feb 1, 2023, 4:02 AM

#

can you access bios if you have a monitor connected just to that port?

fossil dawn Feb 1, 2023, 4:02 AM

#

good point

#

ill try that

wild cedar Feb 1, 2023, 5:06 AM

#

fossil dawn ill try that

fossil dawn Feb 1, 2023, 6:58 AM

#

Nope

#

#

#
