Question Random colorful pixels on the second monitor.

[manosgms]

Hello there.
I have a little problem for like 2 years. The problem is that sometimes there are some colorful pixels that appearing on the second monitor. They are appearing on the discord window or on the steam friend list window etc.
The problem is that its really random, like one day they will appear and the other day everything is fine. But the interesting thing is that when i move the cursor on the pixels they go away.
Do you have any ideas what is causing the problem ?

System specs:

i5 3570 + Cryorig H7
8GB Ram DDR3
ASUS H61M-F
AMD RX 480 (SAPPHIRE NITRO+)
500gb HDD
128gb SSD
Thermaltake Smart SE 530w
Windows 7 64-bit

Could be a damaged display cable, could be a problem with the monitor. I doubt It's an issue with your PC hardware though if It's fine on the main monitor. Have you tried using a different display cable for your 2nd monitor?

First of all ty for your reply.
i will try a different cable. I think that the 2nd monitor is ok. Ive done multiple tests on my pc like some benchmarks for GPU and CPU, mem tests and i did a check on my psu. everything was fine. So maybe its the cable.
Thanks again!
