Running current drivers (536.40) and have switched ports (problem exists on all video output ports on the card), switched cables (current cable is brand new out of the package displayport 1.4) and even switched monitors... the problem persists. The "problem" is that every now and then the monitor will go black for several seconds before recovering, and at least once a day the monitor will go black as if it went into sleep mode but will not wake. Only way to recover the monitor image is to unplug its cable and re-plug it, then the picture returns.Video dropout on GeForce is probably a shoddy DisplayPort cable, especially if it's variable refresh rate. There was also a hotfix driver released recently to address intermittent display blanking on DisplayPort Adative-Sync panels.
It's probably not the card. GeForce just isn't very good at standards-based display compatibility.
Try 539.06. Also make sure you're buying cables that are specifically certified and listed on the VESA DisplayPort website. These cables sustain an insanely high data rate over (electrically speaking) very long lengths, and most non-cert cables can't hack it.Running current drivers (536.40) and have switched ports (problem exists on all video output ports on the card), switched cables (current cable is brand new out of the package displayport 1.4) and even switched monitors... the problem persists.
