Gefen ToolBox HD Scaler Solves Integration Issues
May 13, 2011
New high-definition 1080p scaler from Gefen improves multi-display system performance with switchable digital audio inputs.
Gefen has a new solution for integrating audio/video systems using displays with different native resolutions. The Gefen ToolBox HD 1080p Scaler will automatically scale up or down any high-definition signal to meet the maximum resolution supported by the connected HDTV display.
When used in an installation with more than one display in the room, such as in digital signage or home theater, it allows 1080p resolutions to be viewed on displays with 1080p full HD capability, while scaling the lower-resolution display to its maximum resolution.
For example, when sending a hi-def signal to four displays, one display may support 720p maximum resolution, while the other three displays support 1080p full HD. Previously, installers would have to set the source to 720p, the lowest common resolution among all four displays, to ensure a seamless distribution. But when the HD 1080p Scaler is connected to the 720p display, it will accept a 1080p input and downscale it to 720p, while all other displays receive 1080p full HD.
In a home entertainment scenario, you might have a 720p projector and 1080p display both connected to the same audio/video source. In this case, the HD 1080p Scaler can be connected to the projector to automatically downscale the signal to 720p, while the display will receive a full HD signal.
All video resolutions can also be manually scaled up or down to accommodate any type or size display using HDMI.
Three switchable digital audio inputs and outputs support coax, optical and HDMI devices. You can input coax or optical audio and bypass the HDMI audio or output it as HDMI audio; you can input HDMI audio and output it as coax, optical and HDMI. All three audio outputs are live. Users select their audio using the menu button, RS-232 or IR remote.
