Dual Monitor "ping pong"
ASUS P8Z77-V LX has an on board INTEL HD 4000 Video that has VGA, DP, DVI-D, HDMI, so I thought we need another monitor on this thing.
I hooked up various combinations and it flash screens on boot up but once booted would not recognize a second monitor.
It had the "Generic windows driver" installed, so I got the latest one from ASUS and it seems to be installed.
....however, this is where it gets really weird ....
Both monitors display stuff, but original monitor goes black and then active every 4 seconds and the computer beeps every time it does it.
If I drag something into the original monitor it goes back to the other one in 4 seconds.
If I look at the control panel it displays that 1 display is present and then 2 are present and then back to 1. The identify feature works as well.
Its like my PC has gone blonde (it can't seem to figure out what it is.)
If I remove the cable to the added monitor I can revert to the initial 1 monitor system that works OK. If I plug in the second monitor it reverts to the ping pong mode.
This looks like a driver issue, but maybe its a bios thing. I'm out of ideas.
