Question: I want to connect my PS3 to my monitor using your box? Please help.
Answer: We do suggest using AT-HD620 as it is a scaler converter box which will be able to display your HDMI sources
at the highest resolutions up to 2560x1440. However if you do decide to go with DP400, you can use our converter
without additional devices at only 720p. Make sure to set 720p prior connecting it to the DP400. Even Though DP400 is
able to pass-though very high resolutions, the Xbox or PS3 users will only be able to view 720p because iMac 27” doesn’t
accept 1080i or 1080p.

Answer: The iSight operates through the usb of the 24” LED Display, Please plug in the USB from the monitor to your
