Optoma EX525ST

Hi All,

If anyone is running an Optoma EX525ST projector could you please let me know how you have it set up: distance from screen, size of image, resolution etc.
I have currently a single projector set up but am not happy with the quality of image being produced, I can forgive the 'grid' effect but the quality of image is very disappointing, AI planes appear very 'blocky' and text in some places appear very blurred even though I have played with all settings.

Responses much appreciated
Thanks
Mike
