Frequently Asked Questions

Question: Does this monitor mount support 27" monitors in (landscape landscape landscape) orientation as well as in (portrait portrait portrait) orientation? If so, what clearance remains from the desktop to the bottom of the monitor, when in either orientation? (I ask because I have a center channel speaker that's ~7 inches tall, and would prefer to have the monitors sit above the speaker when in portrait or landscape mode.) Answer: This mount does support 27” monitors in landscape x3 or portrait x3 orientation. The height to the monitor bracket is 18.29” (middle of mounted monitor). If your monitors dimensions are 27” wide, there will be clearance of 4.79” below the monitors in portrait orientation.
