The Acer H5380BD 3D projector can be operated only with the remote control. The image quality of the 3D projector I feel as well. What has me personally very disturbed, is the annoying hum of the fan. I'm not sure if I just had bad luck with my copy, or whether this Acer projector basically has a pesky fan. I have now for the BenQ TH681 (camp = 1638 & creative = 19454 & creativeASIN = B00HR2PII8 & Linkcode = as2 & tag = bravo05-21) decided. The is a bit expensive, but the image is razor sharp, the colors come across well and above all: no annoying whirring more!
