Question Random parts of both monitors flickering with different colors?

[vikoss]

Hello, I hope everyone is staying well and safe!

It has been a few days since I've had this issue. Randoms parts of both of my monitors start flickering with random colors. At first this happened when I entered a game, then it started happening even outside a game.

I have checked the cables of the monitors both are fine.
The flickering stops when I plug out the monitor using HDMI to DP cable.

Hardware info:

Monitors: x2 DELL SE2717H/HX (1080p, 27 inch, 75 Hz)
One of the monitors is with an HDMI cable, the other is with a HDMI to DP cable; Also I've set both monitors to 60 Hz hoping that would have some effect.

CPU: Ryzen 5 1600 - stock
GPU: RX 580 Powercolor Red Dragon - stock
MOBO: ASRock X370M Pro 4
PSU: HIPRO HPA-450W
RAM: 2x8 GB T-Force RGB @ 3000 Mhz

I hope all of this info is sufficient, if not, please do let me know what else I need to provide.

I am currently using a placeholder 6 years old phone and tried taking a photo, you can find it here:

The colorful rectangle on the bottom of the photo is what happens.

Hope you're well as well!

You actually need more than 450W of power for the entire system while working with an RX580 GPU. You should be looking at a 550W unit at the very least. Also, to rule out your GPU being the issue, take the GPU onto a donor system with more power available than the GPU needs to see if the GPU is damaged(causing the artifacts).

Thank you for your reply!

I will look into upgrading the PSU.

As for the GPU, I can arrange this with a friend of mine having 700W PSU. Once the card is added there, what steps should I take to rule the GPU out? Bebchmark or? The thing is the GPU is working just fine on 1 monitor.

I just ran Heaven and below are the results. There were no issues, flickering etc during either of the tests.

This is the result of the benchmark done on single monitor:

Here's the result on 2 monitors:

Update here: did a 30 min Furmark test and no issues. The moment I pressed X to close the Furmark window, both screens flickered a couple of times.
