Summary: Projects well, though it's really more appropriate for a large room and screen than a small conference room. The HDMI seems to be a better choice than the VGA connection if you can use it. Also this model doesn't zoom very well, more of a software zoom than hardware. The little rubber cable that links the lens cover to the lens came off almost immediately and couldn't be reattached by any means I was able to use, weird little fishhook arrangement.
Summary: We are using this in a large boardroom for online training and demonstrations. It has a good picture on our 8 ft screen. Runs quiet, so it does not interfere with handsfree telephone conversations.
