I hesitated with a Full HD model, but that had not the 3D option. Because I was afraid the volume of ventilation, arc en ciel effects and the fact that it is not Full HD precisely. The reason prevailed over passion (especially the budget), so I finally acquired the unit which is almost half the price of the 1080p model I had selected. For the noise level is almost inaudible in more than one meter away. The arc en ciel effects are present but strangely there must be an addictive effect and with time we are actually more attention. For the 720p, I plan on a screen of 2.30 m wide and as we can not see the pixels HD show was at the rendezvous. The investment is the tricky part if you do not wish to use the keystone correction option. And there's no 3D glasses supplied with the camera (any model DLP Link compatible). Finally Acer has 2 almost identical references (much to handle for the search engines) and the H5360 H5360BD the only difference between these two references is the version of the HDMI 1.3 and 1.4a for H5360 for H5360BD. Careful not to be deceived when purchasing only the second is for connecting directly to a 3D bluray player.
