The hotspotting occurs much more severely when both the projector lens and your head is at or below the bottom of the screen. The hotspotting is not noticeable during complex bright+dark scenes, but is very clearly noticeable during medium bright scenes and very bright scenes.
There is less hotspotting if I stand up on the sofa, so that the projector light reflects off the screen at a more comfortable angle (ie, like a mirror reflection).
The hotspotting doesn't bother me all that much - I'm just at temporarily a very bad situation:
- Only 8 feet viewing distance
- I'm sitting to the side, not in front (because projector is immediately behind sofa at head level)
- Not sitting at opposite angle of lens (ideally, it should be lens at top edge of screen, my eyes at the bottom edge of screen - for a more efficient reflection of light to my eyes, as proven by standing up on the sofa for my head to be at the top level, while the lens are at the bottom level)
Also, the screen snaps was manually drilled nd positioned so there are some slight imperfections (they will be adjusted this weekend). I didn't buy this screen new, and I think it was a Draper reject that I've resurrected https://www.avsforum.com/ubb/smile.gif
But at the price, I really can't complain as it took me only 2.5 additional hours to fix the screen frame...
Once the projector gets installed on the cieling, the hotspotting will greatly dissappear. The hotspotting I talk about here, is that one end of the screen is noticeably dimmer than the opposite end especially while I watch a bright movie like Prince Of Egypt.
Either way - the image is definitely
more three dimensional. Laurence is also right - the increased contrast also helps reveals source defects more clearly (ie compression and grain artifacts in a movie such as 'Carrie').
The M2500 also let me literally double my screen surface area for 16:9 movies, while having a brighter image at the same time as reducing my projector's contrast.
All note: I like what I see when I stand immediately behind the pedestral mounted projector that's sitting behind my sofa - that's close to where my head position will be when my sofa will be moved back once the projector is on the cieling.
I'm just saying, be wary if your only permanent seating position is with your nose pressed against the screen (ie less than 10 feet) while at the same time sitting to the side of screen center. https://www.avsforum.com/ubb/smile.gif
The screen does indeed looks amazing when you sit in or near the center at a seating position of about 10 feet or greater. (as I can see, when standing behind the projector currently in its floormount mode)
You won't run into the assembly problems I did, if you buy a new Draper Cineperm. I took the risk with a returned (and unknowingly defective) screen someone offered to me at a "price" I couldn't resist. https://www.avsforum.com/ubb/smile.gif
Most people don't have problems with new Cineperm's and AVSCIENCE will exchange the rare defective screen.
