Is your model name G713IC?
I'm sorry I don't see the horizontal white stripes in your screenshots.
If it only be seen on the screen of your G713 laptop, could you please help to change to blue wallpaper and then take a photo about the horizontal white stripes?
For bluetooth issue, have you tried different bluetooth device, but all of them get the error?
