Using a standard HDMI cable to transmit high definition audio/video at a long distance will result in digital degradation. X-EQ can correct digital error and provide 8dB input equalization to compensate for cable transmission loss. It will eliminate digital noise (sparkles) to ensure you receive a perfect HDTV picture after long cable transmission. Connect the long cable from the source to the X-EQ and place the X-EQ close to the display device. Supports HDTV Resolutions up to 1080p Supports PC Resolutions up to UXGA/165MHz.
