I didn't have this problem on my old 23" 1080p monitor. Now I get a kernel panic, and it seems to be randomly. I can recreate the problem when launching a specific game, which is graphically more intensive. The rest of the times, it will at some random point cause my system to reboot.
System specs, i7 4790k, asus strix GTX 970, asus sabertooth z97 mk2, El Capitan 10.11.3 (15D21), monitor is ACER x34.
One of the kernel panic logs:
In other logs last loaded kexts vary, altho often it is com.apple.filesystems.msdosfs. Cpu # vary. Kernel Extensions in backtrace are same.

Possible causes of the problem and fixes done:
1) Virtual box kexts have known to cause trouble.
- Removed virtual box, and uninstalled kexts.
2) HWMonitor GPU and CPU sensor kexts have caused random errors in similar cases.
- Removed HWmonitor and uninstalled kexts.
3) USB hubs sometimes has caused problems to me in the past.
- USB hub is not attached, kernel panic still occurs.
4) USB microphones have known to cause problems in similar systems.
- USB mic is not attached, kernel panic still occurs.
4) Problem occurs with Display Port and HDMI.
- Tested both Display port and HDMI. Can cause kernel panic loading a specific intensive game. Haven't tested with DVI.
5) G-Sync technology is causing it.
- Have anyone else experienced problems with adaptive sync technology in their monitors? It's the only possible explanation I have left. But it shouldn't affect the system stability from my understanding.
