Bought this screen for our new projector. Problem is the screen area isn’t 16:9. Width is as advertised but the height is 10cm to short making it 16:8. contacted PBTech for a replacement and got no where. After months and months of chasing we’ve given up and thrown the ‘ling large’ box out. Will live with the image projecting onto the black area top and bottom. Apart from the screen dimensions being wrong the screen works fine.
