Are you having problems with 4k and your Display Port cables?

[robble]

Got myself a new Samsung 4k monitor and kept having all kinds of display issues. lots of research led me to believe it was my Display port (screwed up thread title) cable. So I started trying different ones. Of course I started with cheapies and when they had issues too I started getting more expensive cables. Well to make a long story short, I tried Abbot 5 different cables with varying success but nothing that seemed to work perfectly.

enter the most expensive cable I found. but...
IT WORKS. Perfectly.

Yes, I am.

But I'm happy.

I just ordered my first 4K monitor. I'll keep this in mind if I have any issues.

Price of the cable has nothing to do with its quality. It is actually the opposite: the more expensive cables are usually longer, and therefore more prone to failure. To summarize: el-cheapo monoprice 6ft display port cable would suffice.

Looks at post count, then back to shilltastic post. It's a toss up ¯\_(ツ)_/¯

Plus the DisplayPort specification only guarantees signal quality of full bandwidth up to 3 metres for 1.2, 2 metres for 1.3 and 1.4. That is the tradeoff you have to make as bandwidth needs increase. If you're trying to run a 4K monitor at 60 Hz over 6 metres of cable then you're going to potentially have issues.

What issues?

Like unable to wake from sleep mode, screen going to half screen (vertically), and just plain old lost signal sometimes. The half screen (full picture scrunched up) was the most common happening several times a day.

If you got a cable that works for you then great. I had to try several before I found one that worked 100% of the time.

I've had issues with displayport cables and my HP Envy 34C (3440x1440). Tried multiple cables. The fix has always been flipping the cable around (PC to monitor = Monitor to PC).
