What is 4K or Ultra HD (UHD) and what does it mean to me?
4K resolution is 3840x2160, or 4x the resolution of 1080p. A display that can support 4K resolution has an extremely large pixel canvas and can show a tremendous amount of data. Many display technology manufacturers are now producing 4K products (monitors, projectors, video walls, etc.). Just about any computer can be a 4K source with the correct graphics card and supporting hardware.

How far can a HDMI cable be run?
There is no exact science or answer to this question. There are a number of factors that need to be evaluated such as the strength of the signal leaving the source device, the quality of the particular cable (gauge), the resolution of the video being carried, and whether the cable is an active or passive version. The best advice is to use high-quality cables for passive runs up to 30 feet. Beyond 30 feet, use either active HDMI cables or twisted pair/fiber extenders.
What does the term Bring Your Own Device (BYOD) mean?
It is the increasing trend toward employee/student/client-owned devices within an organization. Smartphones are the most common example but many people also take their own tablets, laptops and USB drives into the communication space. The issue with most audio/visual enviornments is that they cannot accept a seeminly infinite number of proprietary connectors and adapters needed to connect. Wireless presentation products are becoming increasingly more popular to support these devices.
