Displayport causing nVidia driver crashes ?

[T3X4S]

I know it sounds weird, but I think I have figured out what the problem is, but now I need to figure out if its my monitor or video card.

I found other posts on nVidia forums with people experiencing the same exact thing.

When my computer goes to sleep, or I turn the monitor off - it causes an nVidia crash.  My monitor is an Asus PB278Q connected to a 760GTX via DisplayPort.

Most of the time what happens is when I go to sit back down at the computer, it is unresponsive to wiggling mouse, or hitting keys on keyboard. The monitor gives me a steady blue light showing a live connection to the computer, but no image.  The only thing I can do is to reboot the system.

Every once in a while, I will be able to get to a desktop and will get a popup saying nVidia driver crashed and recovered.


My question is, has anyone heard of anything like this ?  It seemed kinda far-fetched, but when I saw others experiencing the same thing - I knew I was on to something.


Basically, I need to determine if it is (A) my DisplayPort cable (B) My monitor's DisplayPort, or © My video card's DisplayPort.

The only spare cable I have right now is an HDMI which I will use to begin my process of elimination tomorrow, but thought I would post in case someone knows a little about this issue.


As Always, Thanks for any Input -

Test monitor by hooking it to your laptop.

 

Did you reseat the video card ?

 

Reinstall video drivers ?

 

Reinstall chipset drivers ?

 

I would swap out the video card for another, if possible.

Well it appears to be the DisplayPort on the video card.

I swapped it for HDMI - and no problems.  The crash I was experiencing when streaming video to my TV has not happened either.

I did a clean install of video drivers, and that did nothing.  But as soon as I unplugged DisplayPort and used HDMI  -- all is back to normal.

The surprising thing about all of this is it stopped the streaming crash.  I use serviio to stream video to my TV & it was crashing - I thought it was a bandwidth issue because I noticed how crappy the Verizon Fios router is - but it was the nVidia driver crashing on my desktop which would cause serviio to stop working properly.

So all is fixed and perfect again - all because I moved to HDMI

Now, is there any negative to using HDMI over DisplayPort ?
