Display port not working properly

[sandals100]

So I purchased a new monitor and am now using Display port instead of HDMI (which my old monitor was using). The problem I am facing now is that if I turn my monitor off and then turn it back on it looses the signal of the Display port and keeps saying 'not connected' (or something along those lines).. Does anyone know a fix for this? I have a Benq GW2765HT and a GTX 760. I have my computer set in high performance so there isnt any power saving features for it activated AFAIK.

Also I am on DP 1.2

Usually this is a result of a DisplayPort cable which is not VESA-compliant and has the 20th pin connected, which leads to handshake/signal negotiation issues.

According to Wikipedia, the 20th pin is for power. This is all I found, so it may or may not be correct. http://en.wikipedia.org/wiki/DisplayPort#Overview

That's correct, it's the 3.3V power. Apparently it's not normally supposed to be connected, and when it is it feeds 3.3V power back into the graphics card which creates problems.

Here is VESA's official comment on the issue:

"Recently VESA has experienced quite a few complaints regarding troublesome DisplayPort operation that ended up being caused by improperly made DisplayPort cables. These “bad” DisplayPort cables are generally limited to non-DisplayPort certified cables, or off-brand cables. To further investigate this trend in the DisplayPort cable market, VESA purchased a number of non-certified, off-brand cables and found that an alarmingly high number of these were configured improperly and would likely not support all system configurations. None of these cables would have passed the DisplayPort certification test, moreover some of these cables could potentially damage a PC, laptop, or monitor. We have not seen problems with the cables supplied by major computer brands, or major computer accessory brands, nor have we seen any problems with any of the cables that have been DisplayPort certified."

From what Glenwing posted, it looks like you need to buy another cable. Preferrably one that is DisplayPort certified.

Well, you can try covering up Pin 20 with electrical tape (it's the pin closest to the angled corner) but you'll need some pretty fine taping skills. Other than that, yeah you'll need a different cable.

Ok, what I'll try n do it go to the shop and see if they are willing to swap if for me. If not I'll get a new one.

I also have experienced this problem, except the cable came with the monitor itself... Kind of a bummer to know I paid so much for it and yet Asus can't include proper cables. I guess this explains things though, thanks!
