Thank you for joining the Intel communities.
Please uninstall your driver and then reinstall it, you can download the latest Beta driver for this Intel® graphics here:
Once you uninstall the driver restart your system and then reinstall the driver from the link provided above.
What are the games that you are playing?
For the display port, do you have another cable that you can try?
I have tested I available drivers including final and beta versions. Even the the old driver provided by ASUS website.
I have tested Graphic driver with one game that as you can see it is Civilization V. all drivers had serious problems in running it but the latest beta version was a little better.
In term of DisplayPort problem i have to say yes i do have another cable and it is original monitor cable and it has the same issue. Even the latest beta version does not help much.
In this case Civilization V is an older game and your system is newer technology, I recommend contacting the gaming developers or through their forums to get a patch to make it work better with this system.
About the displayport, please access the Intel® HD Graphics Control Panel, select display and set the resolution you want, in this case I suggest using the highest resolution and apply the changes.
Try again and see how it goes.
Also I will appreciate if you can reply with the Dxdiag file.
In the "Run" window, type "dxdiag" and click OK. A "DirectX Diagnostic Tool" window should pop up. In the window that has now appeared choose "Save all information" After you've saved the file, please attach it to your thread.
About the game I brought it up for you to see the problem. There are some problems like this in other apps like android simulators like Nox app player or Bluestacks as I mentioned it in first post.
About the DisplayPort I have visited intel graphic control panel several times but everything is fine and it is set to highest resolution (3440x1440) but problem occurs when I turn off the display (Not standby) and turn it on again. It start to recognizing the display and it recognize the display resolution wrongly but it corrects it itself after a few seconds.
I am using LG 34UC97 monitor if it helps.

Try getting a monitor .INF file from your monitor manufacturer website or contact them.
A monitor driver supplies configuration information (an .INF file) used by the operating system to implement the plug and play (PnP) features of the monitor. This configuration information includes supported refresh rates, screen resolution, and color quality settings.
Here is the website for your monitor:
Here is the Civilization V minimum and recommended system requirements posted.

I have contacted LG to get the .INF file.
Do I have to attach it here or what?
About the game as I mentioned before the problem is not just the game and other apps have the the same issue.(By the way my PC has the minimum requirement for Civilization V)
Did you get a patch from the game developers to run the game with this graphics version?
If yes, you will need to wait for a new graphics driver in order to solve problems like this.
If you get the INF file just go ahead and install it in your system.
The game is not important. forget it . please fix other apps like android simulators.
I have got the .INF file and installed it but it does not help and the problem still persist.
Something is wrong with intel graphic driver.
What about the Displayport? It is much more annoying that other problems.
I was doing a lab today to reproduce this issue but I do not have this problem, I tested it with the resolution 3440 x 1440, tested with 3840 x 2160 at 60Hz refresh rate but I did not experience this problem.
I suggest trying different cables, others than the ones you have, update the BIOS and all the drivers in your system as well as Windows update.
