I just upgraded from the Hd27 to the Hd70. The Hd70 is currently being shipped. I have a Greywolf 92" (version 1) from before and now the Hd70 is coming with a 92" matte white (1.0 gain). I will be ceiling mounting the Hd70 (about 7.5 foot ceilings). Just wondering if the Greywolf is going to be a problem (brightness issues) due to the ceiling mount (I know that table mount is preferred). Opinions of using the greywolf ceiling mounted vs a matte white screen would be appreciated. Thanks in advance.
