2160p@60hz display port cable

lude1962 · 13 May 2015 at 08:29

I am on a quest to find a 3m one that works at the res and refresh in the title, anyone using one they can recommend?

I've been doing quite a bit of research on displayport cables, it seems there are very few which are compliant. The reason they don't comply is because they link pin 20 at each end. This is a power line designed to power any adaptors you have plugged in, the cable itself should not link this line since both a monitor and gfx card have power on this pin (adaptors could be at the monitor end and/or PC end).
Non-compliance may not cause any problems for some people, others (like myself) have experienced issues with it causing "displayport link failure" errors. The problem seems to affect AMD cards more than Nvidia.
There's one cable which I can actually find to buy, it's model number is HQSC-050-3.0
Note that it says it's a 19 pin cable (displayport is 20 pin), it doesn't connect pin 20 and people have confirmed this.

Here's some links to the problem:

3 Meters. I don't think that length will work at all even if you buy the best cable in the world which is Lindy Cromo like what I've got but I went for 2 meters. You could try it I guess but it's really close to spec 4k/60. You basically have to buy the Lindy Cromo from Lindy for about £25 but yeah out of the 7 different displayport plain cables I have it's the only one that doesn't ever flicker at 4k although some others only flicker some of the time. Tested on 2 different gpus and both a 4k tv and a 4k monitor to make sure my individual experience wasn't down to my specific hardware for you.

I've just ordered up the HQSC-050-3.0, will have to see how it goes.

Thanks for the info gents.

do u recommend "2m Lindy CROMO Mini DisplayPort to DisplayPort Cable" even for 1440p@144Hz ?

I'm using 295X2 and BenQ XL2730Z and I'm experiencing a problem with "black-screening"..

Yes. There is not a higher spec cable manufactured for displayport anywhere in the world. I have a few of their cables.

When ever I have had monitor display problems with the supplied cable buying a Lindy cable DVI or DP always sorts out the issues.

fat4l · 30 Jul 2015 at 15:53

ok thanks guys, already ordered it !

lets see tomorrow when it comes

Does this mean the top cable is working flawlessly, the second not at all, and the third intermittently?

This "Doesn't work with 4k resolution" according to the one Amazon review... Which leads me to believe it's DP1.1, and thus won't work with 3440x1440?

This problem's really annoying, and I still can't find a 19 pin, DP1.2 cable.

He seems to say it's working in another post though.

Also, isn't it possible to cut the 20th on the connectors so that it's unable to transmit anything?

I was led to believe that no manufacturers still had the pin-20 problem. I tested the various DP cables I have, and none of them connect pin-20. Of those, the only ones that I know the brand of are StarTech, and they work fine at 2160p@60Hz, including a 3m one.

Theoretically, but the small size of the pins mean you would need to be improbably dextrous.

Have you ever repaired bent LGA socket pins? How would it compare to that?

well, cable quality is fine...
However it doesnt solve my issue.
So ......keeping th cable, and max volts I can put to my gpu1 is +60mV.
Its prolly a gpu that is causing it butits really weird.
