Sorry to hijack the thread, but thought that perhaps Neowulf can comment on the Masking mechanism of the Monoprice screen. I submitted a question in another thread but didn't get any responses yet.
I bought a 120" Monoprice multiformat screen but having problems with the lower masking panel, it's not retracting into the drum. Monoprice sent me a replacement and the second one has the same problem. Wondering if it's to do with my assembling skills or there's a more systematic problem.
Would appreciate any thoughts on this, thoughts I'd ask the group before calling monoprice again.
