Hyperpixel 4 unusable display


#1

Ive just got around to install my HYPERPIXEL 4 display on my raspeberry pi3 b+ and have not been able to achieve a satisfactory display. I am wanting to use it to display data from my weather station.
The text is very blurred and broken and there are lines that appear on the screen horizontally when i am move the cursor. I have looked through the forums and read advice on similar issues and have checked correct seating and psu etc. I am using an official pi 3 psu.

Any help would be appreciated.
