Cables malfunctioning? Maybe?

[Krik00]

This is a weird one. My setup consists of 2 monitors, one connected via HDMI, one via DP. When both connected, the one with DP shows some weird horizontal lines, but when I disconnect the second one, it works just fine. I was thinking that maybe either cable is malfunction, or that they may be interfering with each other. I'm now ordering new set of cables to try out, for I don't have second cable of either type. What do you think?

What are you using as a video card?  Does the video card you are using have the "UMPH" to support two monitors?  Or are you not using a video card and using integrated graphics instead?  Just because a video card has two graphics connections for a monitor doesn't necessarily mean it can provide what it takes to get a good picture out of them.  My video card has several different types of video connections but I know it doesn't have what it takes to output a good signal on all of them at the same time.  If using integrated graphics, it would be a good bet the system does not have the "UMPH" to power two monitors.  Just something to consider.

I'm using strix 1060, and haven't heard of UMPH (except for Roblox memes xd), but it has four outputs and would be shameful if it haven't handeled it...

By "UMPH" I guess I was trying to say "strength" or "power".  But I think you got what I was trying say.  Hope that you are able to figure out what is going on and get the problem fixed.

I got another set of cables, didn't help. I tried to fix it on software side and discovered that when I set both monitors on 60Hz, the lines disappear, yet when I put one on 60 and the other on 144Hz they reappear. Thus, cables are not the issue and neither is the monitor. I was thinking maybe the GPU cannot handle such amount of Hz, but it adds up to 205Hz. I have read articles about people running 240Hz panels off 1060, so  I am really lost now. Maybe it has something to do with syncing different frequencies, I dunno. You got any idea, pal? Thanks in advance.

You didn't say what the video card or the monitors are?  Are the monitors identical?  Seems like you may have found the source of the problem since the lines go away when both monitors are set to 60hz.  If the monitors are identical and the problem disappears when both are set to 60hz, does the problem go away if both monitors are set to 144hz?  Can you set both monitors to 144hz?
