Hey guys,
Now that I bought 3 new monitors due to the blackscreen issue I have a new problem
ok
GA-Z77X-UP5 TH with a i7 3770k ivy.
Can't figure this one out.... I have been reading extensively the MOBO manual and forums. I know about lots of issues and I thought I bought the right things to not have these problems.
I can only get 2 of three monitors on at one time with HD4000
I specifically built this machine with THIS MOBO to use WITHOUT a video card since intel and gigabyte were HERALDING this so loudly. I am NOT getting a ded. video card--DO NOT TELL ME TO I NEED ONE. 
you can see the mobo will support 3 monitors:
GIGABYTE - Motherboard - Socket 1155 - GA-Z77X-UP5 TH (rev. 1.0)
ALL MONITORS ARE THE SAME
ALL OF MY ADAPTERS WORK PERFECTLY from monoprice TB>DVI I had all 3 monitors visible at some point when switching them around so I know for a fact the adapters are not the issue.
Here is the setup.....
monitor 1: thunderbolt port #1 out > TB/DVI adapter > DVI monitor input
monitor 2: thunderbolt port #2 out > TB/DVI adapter > DVI monitor input
monitor 3: HDMI out > HDMI/DVI Adapter > DVI monitor input
ONCE AGAIN ****ALL OF MY ADAPTERS WORK PERFECTLY*****
windows Graphics sees all 3 and I can switch between them, but all 3 will not work at same time.
Intel graphics only shows 2 monitors....
windows graphics sees the 3rd monitor but I cannot extend the desktop to it.
I have the latest driver and latest BIOS
What is the deal?
