Hi,
It depends on how you qualify an improvement in performance.
There are three things you can check:
- Screen fabric planarity -> to minimise distortion in the projected image
- contrast
- brightness
What doesn't work is spending more on the electrical version of your manual screen for example.
What does work is:
-> Going for a better build (which would improve planarity)
-> Going for a higher gain fabric (which would increase brightness of the image)
-> Going for a high contrast fabric (which would improve black levels)
If you want to focus on brightness for example, going from a 1.0 gain fabric to a 1.2 or 1.3 gain fabric would improve performance by 20 or 30% respectively. But, that's only the brightness side of things.
I would check with a reseller close to you to see different models and the performance difference.
Good luck,
Otto
