Picture on screen is wider on the left

I have a Grandview tab tensioned screen and whilst the image from the projector fits the screen exactly the left hand side of the image looks slightly wider than the right.If I feed a 4x3 image you can clearly see that the black bar on the left is slightly wider by about 2 inches than the right.Screen is 106 diagonal.
Sony projector mounted on unit app 5 metres from screen.
How can I correct this?

The video looks helpful. Will try this this evening.Looks as though by turning the projector to the right or left I will have put matters right.
Thank you.

Is there any test material on line that I could use to ensure that the projector is in line with the screen or is it simply trial and error?
Would it make things easier to have a smaller image on the screen?

I find a slightly smaller image helps so none is projected onto the black border frame whilst you’re trying to get it square. Once the top and bottom and right and left sides are parallel use zoom and lens shift to fill the screen.
