The AMD graphic card I am referring to is just the card I had before I had this cpu+mobo combo. I was just trying to point out that the TV is not the problem here..
If I use extended mode everything is perfect. It's just clone. And I got a longer cable for my mouse and can confirm that it's not just full screen video. It's always there. A browser window that I move around with the mouse for example.
I have tested the DQ87PG board from my side using a processor with HD 4600 and I was not able to replicate the issue. I tested on clone, extended and single display but everything was working fine for me. You can check the files attached which are the dxdiag and the graphics report.
At this point, I recommend you updating the bios on your computer and installing the monitor drivers.
I have a DH87RL (-402) Mainboard and a i5-4670.
I am using the HD4600 to connect a TV via HDMI and a projector via DVI-HDMI (both FullHD).
I can reproduce the tearing when i use the screen duplicate function in Win 8.1. Latest Intel drivers and bios are installed. Vsync enabled and working in extended or single screen mode.
Very annoying indeed.
I have this issue with only ONE monitor. It's pervasive- windows explorer, flash videos, mp4, avi, mkv, when scrolling a web page....
Almost always a rectangle of tearing in the bottom-left portion of the screen. This is ridiculous.
Intel HD 4600; Haswell i5; z87
Windows 7 Pro sp1 on 160GB SSD
... What gives here? Why must this be so difficult?

If it is happening on the built in display, then
You should check your windows aero settings on win7 and win 8.
Like start menu + aero and select the lower item ...For example I was on the classic theme which does not support aero. For me switching aero on fixed the tearing 100% with one screen. For cloned screen, I haven't tested. But I will keep this idea to select the tv as primary.
Thanks everyone for good ideas and sharing experience.
I personally have been testing the Intel® DZ87KLT-75K board using an i7-4770K and I have not been able to reproduce any screen tearing issue so far.
I recommend you to update the bios and graphics drivers to the latest provided by Intel®. Besides updating these drivers, Installing the monitor drivers and testing different cables are good steps to take.
I have replicated the issue in our lab. It is also being tracked in this thread, https://communities.intel.com/message/222400#222400 .
What I am seeing is a horizontal "tearing" particularly during high action scenes.. However, I only see it when I make the TV the secondary display in Clone Mode. I do not see it when I make the TV the primary display or in Extended Mode. I never see the issue occur on the 24" LCD display, only on the 50" LCD TV. I am continuing to investigate.
I'd be interested in knowing whether the RedFlicker.exe program from Image tearing demo with HD 4600 + Windows 8.1 also replicates the issue in your lab. The symptom is seeing any red on the display; correct operation should show only blue.
This issue has been determined to be expected behavior when in "Clone" or Duplicate" mode while displaying content on two displays. Please see Microsoft Knowledge Base article http://support.microsoft.com/kb/972194
The behavior can also be seen on some non-Intel graphics chipsets as well.
Please see the KB article for workarounds for the issue.
