m15 R1, screen problem

Question

Hello.I am the owner of Alienware m15i7 8750, gtx 1070 max q, 16 gb ram.Installed Display - 4k AUO34EB, XWHYC_B156ZANWhen the laptop is running on battery power, everything is working correctly. The problem manifests itself immediately if I connect power cable. External displays connecting with HDMI works without problems.Problems in contrast areas, faces when I made any activity on the screen. On static frames this is not visible. For example - https://www.youtube.com/watch?v=Fuz36dkfIaU&list=UUfcs3_jSWXSwpF0E-06uDOw&index=1 Thank you.
