displayport cable issues

[frozensun]

So guys,I finally did manage to solve the problem with screen flickering,it was cable issdue.

But really don't get it,the old cable which is from the picture as you can see thinner is 1.2 too but even at 100 Hz I got flickering.

Damn I had to travel 70 miles just to get new cable.

This one is as you can see thicker,thicker=better,right?

Why?

And it's gold plated,does that help too,and why?

So I hooked up the cable revert from 100Hz to 144 Hz (native) and played a game,no issues with screen flickering.

Wtf?Oooh good I solve the problem,but,both cables are v 1.2. just this one is gold plated and thicker.

So I don't get it.

Under specs they only specify running 4K at 60 Hz and 2560x1600 at 120Hz which is not native rez of any 2k monitor,so I expected I can only run at 120Hz,but we will see,today one more time if it wotks at 144Hz without any issues.

So for some unknown reason both older cables (thinner ones) didn't even manage to work at 100Hz,but Delock cable is okay,why?

What pissed me off is that when you purchase these cables you don't see any specs excep cable length and sometimes version of DP.But the old one is 1.2 so it should support 144Hz at 1440p without any doubt and that worked with nVidia card but not with AMD which is a lot confusing to me.

Glad I resolved the issue.

So just want to say if you have screen flickering issues replace the cable!

Gold plating doesn't matter. Thickness means there is probably more shielding between the pairs and overall which improves signal integrity and solves your problem. 

Although that's not always something you can rely on, I've had thick HDMI cables that caused drops with 4K60 while a thin one didn't. 

 

Proper stores and brands tend to stand behind their specs, but your random small shop probably buys $2 cables on aliexpress where the manufacturer says "DP1.2" but whether it's actually compliant or not is a crapshoot.

Well there are specs on both cables one is from assman and other one from Delock both from Germany,but if anyone can tell me why thicker works on 144Hz and assman not even on 100MHz,I would be glad to oblidge.

Well reread my post for a possible explanation...

Well yeah,I do agree but then how do you explain that the same cable worked at 144Hz with nVidia card?

Probably the transmitters on the nvidia card are more powerful / have cleaner signal so that even after cable degradation it's still good enough, but not with the AMD card.
