First, I'd like to comment that this is my first post. This is also my first time using Linux. Any suggestions or advice that you give, please explain it in Barney style. Hopefully one day I'll be in a position to help others with their problems.

My computer is a HP 6815nr.

The specs:

I followed all the steps to make a Kali Linux flash drive. Everything seems to work except the display.

Here's what I observed.
Right after Grub loader auto selects the 1st option. Text is displayed on the screen. At first, the text is normal, but then as the screen clears and it goes through a series of checks, the text appears to have a double effect. I see double of text, with some of the original overlapping the doubled portion.

After the text is gone and the desktop is shown. Again the same problem, except this time everything seems off centered and doubled. Even the wallpaper logo is distorted. Any help would be greatly appreciated!
