Scale one HDMI source down or up to 1080p Full HD

The GefenToolBox High Definition 1080p Scaler allows you to scale one HDMI input to one HDMI output with up to 1080p Full HD and Deep Color. This unit can vastly improve the quality of the image by outputting the video to the native resolution of the display, bypassing the display's internal scaler. Video can be manually scaled up and down in all resolutions up to 1080p Full HD.

This product can also be used to downscale, making it ideal for distributing a Hi-Def signal to multiple displays that do not support the same maximum resolutions in an HDMI distribution system, while still showing maximum resolution on the higher-definition displays. It can also be used for DVI signals with appropriate adapters.

The GefenToolBox High Definition 1080p Scaler is conveniently wall-mountable so it can be easily installed behind the display. This Scaler offers RS-232 control and is field-upgradeable.

How It Works

Use the included HDMI cable to connect the source to the High Definition 1080p Scaler. Connect the display to the Scaler using an HDMI cable. Connect an optical and / or coax audio cable from the source to the Scaler. Another set of optical and / or coax audio cables can be connected to an A/V receiver or amplifier. Connect the 5V DC locking power supply to the Scaler and connect the power cord to an available electrical outlet. Select the audio input by using the On-Screen Display with the front panel buttons or the included IR remote control.
