Update on Video Drivers?

So Brian, any update on the latest video drivers? Current Set up: Dock A01 Venue 7130 Bios A11 Video Driver: 3496 (also tried 3412 with same results below) HDMI output to ASUS VS228 with HDMI to HDMI Cable DP output to ASUS VS228 with active adapter from star tech DP to VGA and VGA Cable The HDMI connection works just fine I get the DP to project to the 2nd monitor as well, but it starts flickering very badly after a minute or so. If we can get this flickering to stop we would have a good set up!
