Hi,
I'm having issues with setting the on board setting to overclock on the x27.
It always seems to enable fine initially.  However when I run World of Warcraft, I get intermittent black screens and lose audio for a few seconds (up to 10 seconds).  It happens soon after I start the game, when I change the volume, or when I alt-tab back to the desktop.  I think it might be playable but it shouldn't behave this way.  It doesn't matter what frequency I choose on NVIDIA control panel (e.g. I like 98Hz), I get black outs as long as the overclock is set to on.  I don't get black screens like this when overclock is set to off.  I am using the displayport cable that came with the x27, which says it's rated for 8K.   I am running an MSI GTX 1080 Ti Seahawk (I have 2 in SLI).  I have upgraded the NVIDIA firmware to support HDR displayport 1.3 and 1.4.  Do they sell a better cable than the one that comes with the monitor?  Would that fix my problem?  Could it be my graphics card or the monitor itself?
Regards,
Dan
