The HDEXT50M is one input over one output HDMI extender designed to carry DVI/ HDMI signals over distances beyond the capability of standard HDMI/ DVI cable. It extends video and audio over a single CAT5e/6 cable up to 165ft. The extender provides auto-adjustment, buffering and signal equalization to maintain pixel-perfect resolution up to HD 1080p/60 depending on the RJ-45 run. To attain full HD 1080p the distance has to be shorter than 100ft. Ideal for relocating your source such as a Blu-ray player or a satellite box to a remotely located display.
