I have the monoprice mount. It comes with a 3" tube and a 6" tube. Thats all you get for vertical adjustment other than the tilt.
1st post, 1st projector. Just got it delivered yesterday from visual apex. Monoprice: mount, flat HDMI cables, powered 4x1 switch, powered 1x2 splitter. I have an 88" BOC over wood frame screen that I painted with Sherwin Williams Gray Screen.
I have nothing to compare it to. All I can say is its awesome to me. I have it in my living room with lots of ambient light. Looks fine to me. I can see how the gray screen helps.
For inputs I have:
Dish VIP622 HD DVR
Pioneer BDP-51FD Blu-ray
I have HDMI issues. I believe its related to the splitter as I had the other stuff before. I am randomly dropping my handshake to the projector and the 42" sony I have connected with the splitter.
I also see the rainbows if I flick my eyes across the screen quickly. Under normal viewing I see nothing. I have to try to see them.
