Hello everyone! My laptop has problem when it's displaying solid yellow/orange/red colour at about 25% of the screen. It will be flashing /flickering black in that situation. I ussually have issues when displaying table with yellow highlight and I confirmed this with paint app to colour my sreen with solid yellow/orange/red color. The only relief is to hide/delete the yellow colour. Tilting, changing lid angle wont relief the flicker. After flickering, laptop screen display will be wavy for about 20 secs. Please help me! Thank you

Note:
Display driver has been updated to the latest version.
